Cruzbike heavy duty rack modifications

Here’s the rack.

A customer called me the other day about getting some Radical Design panniers. He had made some modifications to the Cruzbike Heavy Duty rack on his Quest 20. Talking to him, I became very curious about the mods because it sounded like he was solving a problem I too had observed: no place to anchor pannier bags on the side of the heavy duty rack and no way to ensure the Rad. Design bags wouldn’t touch the rear wheel.

His name is Tor Matson (no relation to me, as far as I know). Here are his notes and photos. He’s happy to make the rack for others if you wish.

Hey Robert, here you go…  Here’s my rack, and a shot of my plush air shock, to boot…

This little aluminum rod bit is what makes it all happen; it’s relieved to fit the CB HD rack. Does require drilling and tapping of the rack. I could make these bits if there’s interest…

Here’s the kludge bit. Having the quick-release option is nice, as you can just slide the rack out of the tube, but the hose clamps aren’t so nice. Could TIG some aluminum tube onto the CB rack for a cleaner look, or fab up a better tube-and-clamp system. This is a beta test mule, function only!

Slipped some tubing over the pannier rack, and got a really secure mount. Solid and rattle-free!

I asked him if I could post the photos and his contact info. in case anyone else wants to order one.
Here was his reply:

Bueno! Post it if you like; I could make those pieces if anybody wants one, but I’m happy to just share the idea; it’s pretty simple to fab and is kind of a custom fit thing anyway, but happy to help if I can… If there’s demand, I could make a batch, not totally sure about the tolerances between racks… Mine took a bit of fitting to be perfect…
Cheers,
Tor Matson
Email him at “maryselapierre [AT] gmail”
You’ll need to add the extension, etc. to that e-mail address.

Have fun and ride like the wind,
Robert

Fairing on a Cruzbike. No, for the front; yes, for the rear. But wouldn’t you rather have an aero helmet?

From a customer:

Any recommendations

Hi James,

Your weekly mileage is fantastic!  Great job!

Fairing on a Cruzbike.

Fairing: front

I advise NOT using a front fairing on a Cruzbike.  (Front fairings work better on traditional, non-Cruzbike recumbents and trikes.)

Although I’ve read a few posts and have seen one photo on-line of people using front fairings on their Cruzbikes, I believe a front fairing is dangerous on a Cruzbike for two reasons: 1) front fairings are heavy and that weight is likely to negatively effect steering; and 2) front fairing are sail-like and they catch wind from your back, therefore wind gusts will cause the front wheel to turn in unexpected ways on a Cruzbike.

I’d also mention that, generally speaking, small front fairings — which would impact steering less — give very little aerodynamic benefit (a customer and I once did a series of tests to measure it).  The main benefit of the small front fairing is to keep your feet warm during the winter.  (And they do this well.)

Large front fairings (like the one from HP Velotechnik) — which would impact steering more — help keep you drier in the rain and warm in the winter (and for this, they are GREAT), and will give more aerodynamic benefit than a small fairing, but I haven’t measured this.  At any rate, it’s hardly worth the downside (on a Cruzbike).

So, I don’t recommend a front fairing on a Cruzbike.  However, you may be able to find posts on the Cruzbike forums of riders using a front fairing on a CB with success.  Also, while there have been rumors that John Tolhurst, the Cruzbike designer, once toyed with designs for a front fairing, it hasn’t been introduced.

Instead of using a front fairing, I suggest you experiment with a steeper recline of the seat.  This will give a significant and comparatively safe aerodynamic advantage.

Fairing: rear

A REAR fairing (a.k.a., tail box, tail sock, etc.) gives significant aerodynamic advantage without as much effect on steering.  (My customer and I measured this as well.)  TerraCycle sells a “Tail Sok” but you’re on your own in terms of figuring out how to attach it to a Quest (or any other Cruzbike).  If you figure it out, please tell me, because I like the TC Tail Sok!
http://t-cycle.com/tailsoks-c-10/?zenid=agq74v3s2s8enu193ef9pu8u85

An inexpensive and practical alternative to the rear fairing is an aerodynamic bag on the seat back or rack, such as those from Radical Design or Ortlieb.  This doesn’t give as much benefit as a rear fairing, but I’ve measured a benefit.

The easiest and cheapest way to improve your aerodynamics is with a time trial aerodynamic helmet which you’ve bought on sale.
http://www.racycles.com/apparel/performance-gear/helmets-aero

In a conversation, Maria Parker recommended using more aerodynamic clothing, such as a lycra race kit (a.k.a., roadie clothing, spandex, etc.).

I believe an aerodynamic wheelset helps a lot, but these can be expensive.

On that note, another inexpensive option is to look at the tires you’re using.  Schwalbe makes excellent race tires, that are also durable, and are available in 26″ sizes.  This isn’t to improve aerodynamics but to decrease rolling resistance.

If there’s a reader out there who has had a different experience, or would like to share a solution they have tested with great success, please post a note.

All best,
Robert

Radical Design bags and panniers for Cruzbike recumbent bikes, no rack required

A Radical Design customer* in England shows how he attaches Banana Racers on a Vendetta, giving the bike 25 liters of carrying capacity without a rack. (*I don't know his/her name but I'd really love to credit the photo and creativity to him/her.)

To carry luggage on a Cruzbike

I strongly recommend the bags made by Radical Design (“RD”) (sold in the USA by New York City Recumbent Supply) because they are lightweight, high quality and many models don’t require racks.
Radical Design bags are also an inexpensive solution because the rider needs only buy the pannier bags and not a rack plus bags. That quality also lowers the overall weight of the luggage system (bags alone are lighter than bags plus rack).  RD bags may be layered for maximum carrying capacity because they’re made of flexible Cordura(R) nylon and many of the bags don’t require racks.

Radical Design bags work well on Cruzbikes but it’s not always obvious how to mount them to the bike. I maintain this post as a running entry, updating it when I have new information.  Be sure to check back from time to time.

Also, this blog post has good information about attaching panniers to a Quest. Similar strategies apply for the Silvio and Vendetta.

 

Cruzbike Quest 20 with Radical Design Banana Racer below seat and Solo Aero on back of seat, totaling 37 liters of carrying capacity.

Note: Solo Racer in both wide and narrow sizes fit equally well, though imperfectly, at top of seat on Sofrider, Quests and Silvio. The wide fits outside the seat cushion and may sag a bit. The narrow fits under the seat cushion and rides a bit high. Both work.

Radical Design bags for Cruzbikes

Solo Aero

Available in “wide” and “narrow” depending on seat width. Solo Aero wide (12 liters capacity).  5 colors available. Requires removal of the Quest 20 or 26’s rack. “Wide” and “narrow” both have 12 liters capacity. Manufacturer’s info.


Universal Racer

Universal Racer (10 liters capacity). 5 colors available.

Solo Racer works too (size wide for bottom of seat, size narrow for top of seat).”Wide,” “narrow” and “universal” all have 10 liters capacity. Manufacturer’s Info.


Banana Racer

Possibly my favorite Radical Design bag: the Banana Racer (25 liters capacity). 5 colors available. Manufacturer’s info.


Which bags fit which Cruzbikes

Silvio 2.0 and 1.5
Solo Racer, narrow, at top of seat, under seat cushion.

Reader question: Ortlieb Recumbent Backpack or Radical Design Rack Bag?

Dear Robert,

I have an HP Velotechnik Speedmachine, using one Ortlieb Classic Plus.  In time it made the rack bend and it touches the rear triangle when the suspension works.  Wanted to move to a rack bag- more aero and balanced.

Read your article about the Ortlieb Recumbent Backpack, but the Radical fits me more IF its convenient to fit to the rack. So how is it compare in that area?

Thanks a lot,
Aero and Balanced

Speedmachine mit Untenlenker
HP Velotechnik Speed Machine

Dear Aero and Balanced,

Congratulations on your good taste as demonstrated by owning a Speed Machine. Before we talk about bags, I need to say that I’m surprised that the rack of your Speed Machine has become bent on one side to the point that it touches the rear swing arm when the suspension is compressed. Have you overloaded the rack? Have you been carrying cinder blocks in your saddle bags? Or sand? Is your rack broken? Is your bike broken?

The contemporary design of the Speed Machine and its rack are such that it’s hard for me to imagine how they could come into contact. Though, I suppose if you actually bent the rack, and twisted it sideways, and bottomed-out the suspension, you could make the two come into contact (while voiding your warranty).

Keep in mind that racks (and the bikes on which they are mounted) have payloads and intended usage. If you exceed that payload, or use the thing for something other than that for which it is designed, you may break or bend the thing, whether it’s a rack or bike or shock or wheel or whatever. The rear rack of the Speed Machine has a maximum payload of 55 lbs. (not kg, but lbs.). The max. payload of a Speed Machine is 286 lbs. (not kg.), including you and whatever bricks and cinder blocks you’re carrying. Bending of the rack (or whatever) shouldn’t occur as long as you don’t overload (and thereby damage) the rack (or whatever). At least, this is true for HP Velotechnik’s machines. For other manufacturers, this may not necessarily be the case.

[Later.] To satisfy my curiosity — could it be true that the HPV SpM’s rear rack can touch the swing arm? — I went over to the shop’s demo Speed Machine here, which has a rear rack that has been (properly) installed and which rack (and bike) is neither bent nor broken. I sat on the rack, all 165 lbs. (not kg.) of me in order to bottom out the shock and see if the rack can touch the frame or swing arm. It doesn’t. It doesn’t come anywhere close. Nor does it jiggle. Nor does the rack bend when I sit my ass on it. If you have a Speed Machine (or any HP Velotechnik) where the rear rack contacts the frame or swing arm, then you have a damaged machine or rack. Was your bike assembled incorrectly? Was it in an accident? Did your cousin run over it with his car and not tell you?

Rackbag Extended
Radical Design, Rackbag Extended

RECUMBENT BACKPACK
Ortlieb Recumbent Backpack

As for the Radical Design Rack Bag versus the Ortlieb Recumbent Backpack, they are both great, durable bags and I’ve used both for hundreds of miles. They are equally easy to mount and un-mount to the rack-top. The RD bag has a nice capacity (30 liters), is lightweight (720 grams), and is water resistant (waterproof fabric, but no waterproof zipper or seams). The Ortlieb is almost half the size (17 liters) and is comparatively heavy due to the excellent waterproofing (980 grams) — it’s so waterproof it’s nearly a dry bag — and the backpack straps are a cool thing; the Ort. also has nice pockets for organizing and a port for the hose from a water/drinking bladder. Both will give you some aerodynamic benefit. The rack on the Speed Machine is short compared to that on touring bikes like the Street Machine or Grasshopper, but my experience has been that both bags fit fine.

In summary, I’d make my decision based on capacity and whether I was riding/living in a wet climate.

All best,
Your Recumbent Bikologist.

Panniers and bags for Cruzbike Quest 26″ and 20″

To carry luggage on a Cruzbike, I strongly recommend — and personally use — the bags made by Radical Design (“RD”) (sold in the USA by me, at New York City Recumbent Supply).  RD bags may be layered for maximum carrying capacity because they’re made of flexible Cordura(R) nylon and you don’t need a rack for many of the bags which saves weight and cost.  It’s a very smart product designed by a very smart Dutch guy.

Radical Design panniers on a Quest 26

I only sell bikes and products that I actually use and I can assure you that the RD side panniers in the medium, small and “banana” sizes will all work on a Quest 26, without requiring a rack.  The Solo Racer seat back bags work perfectly too.

Radical Design Side Panniers

Radical Design’s large, medium, small and banana side panniers fit your Quest 26 or 20.  Get them in the “hard shell” or “universal” width.  There are several approaches to making them work, depending on whether you have a rack installed or not, but I’m most fond of not using a rack when I mount side panniers on a Cruzbike, whether it’s a Quest, Silvio or Vendetta.

 

Q 26 with large panniers.

Here are some great photos of a Cruzbike Quest 26 with Radical Design Side Panniers, size medium.

Thanks to friend/customer, Abram Clark, in San Francisco, for showing how he mounts the RD Medium Side Panniers on a Q 26.  He and I put our heads together to figure this out, but he’s the one that made it real.  Very cool.  It also shows the brilliance of the Radical Design philosophy, that by giving riders a wide range of options, we can attach these high quality bags to a wide range of frame shapes.

This is how the bags look when mounted.  Check out where he can have the center of gravity when he loads them.  Yeah.

 

Abram invented a similar solution for his large RD side panniers on his Cruzbike Sofrider, tying them off to the rack. I saw that and hypothesized that something like this, shown here, would work. Then Abram made it happen. I’d experiment with using bungee cord instead of rope, to allow for the suspension of the rear swing arm, but I think rope is the more durable and longer term solution. Also, bungee cord is impossible to tie in the manner shown here so you’d be forced to use those terrible bungee hooks. Rope is probably best.

 

 

I like how he tied it off to the seat support.

 

Over the seat back.

 

Over the frame and under the seat, to Grandmother’s house we go.

 

Beautiful.

Size small Side Panniers on the Quest 26.  And, will my laptop fit?

A customer writes:

I have a Quest 26 (559) with standard rear rack and need a bag for it.

I plan to transport [my laptop] in a case that measure 14″ x 10″ x 1″. I would also want room for a change of clothes and a lunch and if possible a hydration bladder.

Thanks so much for your help!

Hi R—,

Regarding: Radical Design Side Pannier size small mounted on Quest 26 (559) with standard rear rack.

Attached please find photos showing:

IMG_0163

 

How the side pannier (small) attaches. It lays on top of the seat and on top of Quest rear rack. You can remove it with one hand at the end of your ride. If you prefer, you could put the straps under the seat cushions. You could more firmly attach the rear-most strap to the rear rack with a bungee cord or velcro straps; sometimes this is desirable, but not always necessary.

 

IMG_0166

This is one way to attach the bungee cord from the rear swing arm to the rack. There are many ways to do this. If you don’t feel you need the stretching capability of a bungee cord and you know some knots, thin, lightweight climbing rope could be used instead. An old inner tube could be used also, tied to each side of the swing arm and up and over the rack. The essential requirement is to keep the bag from swinging against the tire.

 

IMG_0168

 

Photo showing my laptop in the bag.

 

IMG_0169

My laptop measures 9.5″ x 13.5″ x 1.5″. It’s a bit smaller than your case, but fits with a lot of room to spare for your clothes, lunch and water bladder.

 

In this set up, I’d put the water bladder in a side pannier and use it to counter-balance the weight of the laptop plus lunch. There are also mesh pockets on the panniers for water bottles.

The Solo Aero seat back bag from Rad. Des. is too small for your laptop.  A smaller laptop would fit.

Happy to help. I like the Radical Design and Cruzbike products a lot and enjoy seeing people using them.

All best,
Robert

 

 

How to attach the Banana Racers on the Quest 26 or 20

The rear strap is attached to the seat brace with a girth hitch. The hitch doesn’t need to be directly in the center, but for those who insist on symmetry, you can remove the seat post and place the straps around the post.  I pull the straps connecting the left and right bags tight so as to bring the bags close to the frame.

 

The front strap can go either on top of the seat or underneath the seat and on top of the frame.  The straps are buckled in the configuration for a “hard shell seat.”
The middle strap goes over the seat. Notice I added a horizontal strip of velcro to the bottom of the seat back. This helps secure the seat cushion when hanging the Solo Racer bags because their fabric sling goes between the cushion and the hard seat back.

Choosing and mounting Radical Design bags for a fully-loaded tour, without any racks

In 2012, I was preparing for a 12-day trip through the Adirondacks and Vermont.  I put together this configuration on a Quest 20.  This could work for a Sofrider and a Q 26 although I feel the rear wheel of the Q26 comes too close to the bottom of the Solo Aero.

For this solution on the Q 20, I removed the rack.  I also removed the water bottle cages; I would use a water reservoir instead. (I would do the same for a Q 26.)

I installed:
– Radical Designs (RD) Solo Aero (wide), behind the seat at the top (where the rack would have been).
– RD Solo Racer (wide), behind the seat in the location where the water bottle cages are.
– RD Banana Racer, underneath the seat.

This provided 47 liters carrying capacity, most of it within the slip stream.  That’s enough capacity for a tour if you pack moderately light and would ordinarily ride with two rear panniers.

In the above photo, a Banana Racer, Solo Aero, and Solo Racer combine to provide 47 liters of carrying capacity, most of it within the slip stream, on a Cruzbike Quest 20 (451 rims). An RD Universal Racer could have been used instead of the Solo Racer.

How does this compare to traditional panniers?  For context, Ortlieb Back Roller Classic rear panniers — the gold standard for touring panniers — provide 40 liters of capacity in the left and right panniers combined.  This Radical Design setup will be lighter than a rear bag Ortlieb setup because the RD bags are lighter and don’t require a rear rack AND because the Radical Design panniers do not use heavy waterproof materials  For waterproofing your “dry-or-die” gear, put it into plastic bags or dry bags.  (For the record I like Ortlieb panniers. I simply can’t find a good way to mount standard Ortliebs on the Quest. Ortlieb’s waterproof “racktop bag/recumbent backpack” mounts fine on a Quest with the heavy duty rack.)

For those who are staying in hotels or B and Bs, you may prefer going with the 37 liters of capacity provided by the Solo Aero and the Banana Racer, as shown here.

 

These are the bags I was using.

Solo Aero wide (12 liters capacity).
Requires removal of the Quest 20 or 26’s rack.

 

 

Universal Racer (10 liters capacity).
Solo Racer works too (size wide for bottom of seat, size narrow or wide for top of seat)
Fits Quest, Silvio, Vendetta.

 

 

Banana Racer (25 liters capacity).
Fits Quest, Silvio, Vendetta.

If you use the Quest rack to help support the panniers, read this.

If you use a rear rack to help support the panniers, there are a few concerns: (1) making sure the sharp rails of the rack do not cut the nylon webbing on the pannier bags.  (Put a section of inner tube around the sharp rails.) (2) Ensuring the weight on the rack doesn’t exceed the Quest’s standard rack rating of about 22 lbs.  You can do this with Radical Design panniers by carefully organizing your luggage so the heaviest weight falls to the front, hanging off the seat or frame. If you know you’re packing heavy, get the Quest’s optional heavy duty rack which has a payload rating of 50 lbs. (3) Keeping the bags from rubbing against the tire.

If you’re using a rack, keep them from rubbing against the rear wheel by using elastic cord (like bungee cords) or rope between the rack and the rear swing arm.  Camping rope, like para-cord will work and so will cheap plastic clothesline.  However, I’m comfortable with my knots.  Others may not be.

Another solution is to install side pannier rails on your rack, like those from Topeak (not available from NYC Recumbent Supply or Cruzbike) although I’m less fond of this solution because it adds weight and cost.

 

RD “Banana” (Side Pannier) size small on the Q 20 heavy duty rack. Sits very close to the wheel.  You can use a bungee cord or rope to keep the bag off the tire.  Or, move the bag forward on the bike, so the front straps hang from the frame, beneath the seat.

 

RD Banana (Side Pannier) size medium on the Q 20 heavy duty rack.  It can touch the wheel but it also hangs outside of the frame, which helps it stay away from the wheel.  Still, you’ll want something to keep the bag off the tire.  Move the front straps under the seat and the bag will hang entirely between the wheels on the Q26.

Have fun and stay healthy,
Robert

What I’m riding in town these days.

This is a Cruzbike Sofrider loaded with groceries, including kale and swiss chard.

For the past few months I’ve been riding a Cruzbike Sofrider around town as my city “beater.”  The Sofrider is a capable commuter and touring bike, but it’s not immediately obvious how properly to attach luggage.

 

Rack.
I’m using an Old Man Mountain Sherpa rack, here shown with standard Axiom rear panniers packed with groceries.  The Sherpa is a well-made, versatile and strong rack that you can install in the manner intended by the manufacturer, which is what we want to do for best results.  I’ve attached the rack’s vertical struts to threaded bolt holes just forward of the rear dropouts.  The forward “horizontal” supports attach to the rear caliper brake bolts.  This is a secure fitting and allows for a decent real world payload.  It is easier to install a seatpost-mounted rack, like the Topeak models, but their typical payload ratings of 20 lbs. isn’t enough for (my) grocery shopping.  For those concerned about weight, be aware that the 32-ounce Sherpa is not lightweight.  Also, note that the rack is rated for a payload of 40 lbs.  My belief is that the rack will support a heavier payload for a short time, but for a longer trip I’d stay below the 40 lbs. payload rating. (Errata: I had  originally written in this post that the luggage is fully suspended when using the Sherpa rack, but the luggage is not suspended since the rack is attached directly to the rear wheel.  If one were to use a seatpost-mounted rack, then the luggage would be suspended.)

Seatback bag.
I’m using a Radical Designs Solo Aero on the back of my seat.  You can buy it from New York City Recumbent Supply.  This is an excellent, well-made, capacious bag of 12 liters volume.  That’s about half a good-sized daypack.  It quickly slides down over the seatback and comes off just as fast.  With the carrying strap it’s easy to manage.  Reflective tape on the back.  Comes in five pretty colors.  I love it.

Wearing a lock.
Another detail that makes the Sofrider good for a city bike is that there is a hole in the frame where you can string a lock.  While riding, I loop a chain-style lock two-times through the frame and under the seat.  The lock hangs a bit loose and sometimes makes noise, but it hangs out of the way of the wheels and contributes its weight in a useful place — right under the seat.

Where are the fenders…
I haven’t gotten around to adding fenders and I’ve suffered for it.  I need to add them soon.  The last rain was cold and wet and dirty.

Sherpa installation.
On the Sofrider, I want to keep the weight forward of the rear wheel as much as possible so the front wheel doesn’t lose traction on the hills.  So, I’ve mounted the rack backwards, with the rear of the rack turned to the front, to bring the carrying rails as far forward as possible.  Then, I mounted the vertical supports such that the curve of the vertical adapter moves the rack forward of the rear axle.  I have also used the fender mounting holes in front of the axle.  This is not so much to move the rack forward as it is to allow me to use my front wheel Pitlocks on the non-drive (rear) wheel.  The installation would be stronger if I attached the vertical supports to an extra long quick release through the axle, but I much prefer to keep the wheel locked.  So, I guess I’m living on the edge a bit.  If I had done this for a customer, as opposed to for myself, I’d have used extra long Pitlock skewers through the axle and mounted the rack’s vertical supports on those extra long skewers, because that is really the right way to do it.  Notice that the mounting rails on the Sherpa come well forward of the rear axle.  It’s easy to load the panniers so the weight is forward of the rear axle.  When the rack is installed like this, the front drive wheel maintains a good grip on the street even with heavily loaded panniers.

Have fun and stay healthy,

Robert

Silvio. Wow, that was cool.

Today (yesterday, really) I finished building the shop’s new Cruzbike Silvio demo bike.  After my last demo appointment ended and I finally had time — after 10pm, after dark — I put on a pair of bright Busch and Mueller lights on the Silvio and took it for a 10-mile spin through Prospect Park and local streets.

Wow.  What a feeling.  I test a lot of cool bikes, but I haven’t had a speed-thrill like that since the first time I rode a (standard frame) time trial bike.  The current demo machine is the stock Silvio with SRAM Rival components and Cruzbike-brand aero wheels.  They’re nice components and nice wheels but nothing out of this world in terms of cost.  However, there is something very special about the frame and overall concept and design.  (And, of course, I did a wonderful job with the build.)

I look forward to putting in some real miles on this bike to see what it can do in the daylight, but, so far, it looks like a champion.

– – –

A couple weeks later: I’ve put in about 120 miles on the Silvio over three rides.  It’s fast, nuff said.  I’m able to stick pretty well with the kitted athletes in P. Park on the flats and rollers, keeping between 20-25 mph.  Maintaining 15 mph up the hill is not a problem.  This can not be attributed to my strength; the team cyclists are much better riders than I am.  I stay away from the pace line and in the wind so as not to cause problems for the others but I work to maintain a consistent distance to get the benefit of being paced.  Being in the wind as I am, my ability to keep up is meaningful.  I fall behind the faster riders when we hit the hill but I’m generally able to catch up once we crest.  The S. is proving to be a good bike for maintaining pacing with road cyclists, so definitely a great option for the rider who wants to move to a bent but doesn’t want to change friends.

The S’s front end (with SRAM Rival) is a lot lighter than the front on the Quest (and Sofrider), partly thanks to lighter drive-/front-end components.  Result is it doesn’t have as much of that “veering” quality that the less expensive CB’s have.  I miss the Quest’s e-ring though and the simple handlebars (I’m still a touring/commuting rider at heart).  I’m still trying to figure out a handlebar position that I like.  The Silvio accepts a Radical Design (RD) seatback bag and RD’s Banana Racer so it does in fact have some carrying capacity; that’s pretty cool.  (I have the RD bags for sale and in stock, by the way.)  There are braze-ons for a rear rack but I haven’t yet figured out (or heard) which one fits.  It feels odd to ride a “day tripper” with skinny tires, no fenders, no rack, no light system; I’ve grown accustomed to touring/commuting machines as my ride of choice.  But speed is fun, I must say, and there’s nothing like knocking out a quick 35 miles as a pre-breakfast ride.  Too bad the cold temps are closing in on us.  I’m just starting to have fun.

Radical Design recumbent bags. Now available here.

I’m very pleased that the first Radical Design bags arrived.  I had high hopes because they also make HP Velotechnik’s excellent panniers, but they’ve more than exceeded expectations.  Wow.  Designed very practically for recumbent riders, the bags are light, attractive, aerodynamic, well-made, and highly adjustable to fit nearly any bent.  Made in the Netherlands, for real.

Radical Design’s Banana small side panniers with 40(!) liters capacity.
Depending on your seat, a rear rack may not be required
for carrying groceries or minimal touring gear.



Radical Design’s bags are unique in that many do not require racks (but some do).  Some slip onto seat backs (no tools required), some simply hang from the seat, and others, especially the larger sizes, while they do require a rear rack, do not require an underseat rack, reducing weight as well as overall cost.  In addition, several of the designs are easily mounted on bikes that do not easily accept racks, like Cruzbikes (CB Quests come with a rack).

The panniers are streamline-shaped and are either tucked under or behind the seat, or partly in the slipstream.  I’ve done day-rides with the large panniers and prefer them over standard frame touring panniers which tend to feel like you’re dragging bricks through the wind.  While I continue to be a fan of waterproof Ortlieb panniers, Radical Design offers a larger suite of products designed specifically for recumbents, greatly increasing the options for bent riders who need to carry stuff.

Radical Design’s Solo Aero 12 liter seatback bag.
That’s a fabric bottle holder on the side.

There is an enormous variety of bag sizes, styles, and carrying capacity, from small, medium, large, and extra-large.  There are small bags for day riders, medium bags for commuters, and their large panniers for touring have as much capacity (70 liters) as an expedition backpack.  Seat back bags come in several different designs to fit nearly every recumbent seat, whether narrow or wide, mesh or hardshell.

Radical Design’s 30 liter Rackbag Extended weighs only 720 grams.
Serves as a soft-shell tail box for improved 
aerodynamics.

They also make attractive and roomy rack-top bags.  Unlike the rack bags designed for standard frame bikes, which are generally of small capacity, Rad D’s rack bags take advantage of the fact that they sit in the slipstream, where large doesn’t matter (if they’re light).  In fact, large can be better: these rackbags serve as a  soft-shell tail box, improving the bike’s aerodynamics and speed while providing ample low-weight storage.

Here’s an interesting comparison.  Radical Design’s Rackbag Extended, versus the excellent and rightly popular waterproof Ortlieb Recumbent Backpack-Rackbag, versus Topeak’s MTX TrunkBag DX:

Bag / Capacity / Bag Weight
Radical Design’s Rackbag Extended / 30 liter capacity / 720 grams
Ortlieb Recumbent Backpack-Rackbag / 18 liter / 980 gms
Topeak MTX TrunkBag DX / 12.3 liter / 1020 gms

There are people who pay huge bucks to save that much weight on their bike and get this kind of aerodynamic improvement.

For those who prioritize color and style, the bags come in five attractive colors: “dusty” yellow, tomato red, blue (royal blue?), “dusty” Dutch orange and then flat New York black.  (New Yorkers, listen, you no longer  have to choose between black and black!)  All bags have good reflective strips.  Water-resistant, but not water proof, making them lighter in weight, but if you’re riding through a lake, put your laptop and sleeping bag in a dry bag.

Have fun and stay healthy,
Robert
