On the USA version, the differences are:
– no snake seal
– no chain guard
– slightly different bolts
– Isoflow cranks
– different rear hub (cheaper)
Additional savings comes from reduced customs duty and shipping.
The other main difference is that if riders want most of the upgrades and special options listed on the HP Velotechnik website, such as light systems, custom colors, upgraded brakes, etc., then we have to build up from the European model.
The price confusion is more psychological. I use the German model as my demo because I like to show the top of the line features. Riders shouldn’t worry too much about the difference in price. Just buy the trike you want. After several years, you won’t think about the difference in price, but you will notice whether or not you own the right trike for your purposes.
