Okay I know this a bike forum but I'm going to run this by you guys because I cant find a "trike" specific forum that's dedicated to the details like Johnny.
I recently perched a used HP Velotechnic S-Pedelec. I have put on about 250 miles, riding between 12-26 miles at a time.
I live in MN with rolling farm land and sometimes use the assist on 1-2 (out of 5) in town or really steep stuff around rivers. I use the regeneration when on long down hill stretch's, my battery seems to be holding at about 60-80%. Now I'm 62 not 22 so I'm not after speed, I average about 12 mph.
I'm impressed with the regeneration of this unit, this is the Go Swiss Drive that is no longer supported by anyone, but it works just fine, the reverse is something I don't need and I think was for people with special needs.
Sooo my question is, if I upgrade to mid-drive can I use the hub for regeneration of the mid-drive?
The hub is a 36 volt, so would I be limited to 36v or could bump that up to 48volts?
If this is too impractical I may switch out the hub to my Greenspeed tandem, then reverse would be nice sometimes.
PS. the HP Bottom bracket (top bracket on a trike) measures 60mm, do the kits come with spacers?
