Hello everybody,
my friend quadriplegic owns handbike attachment for his wheelchair, I think it is some older version of this thing...(it attaches on his everyday wheelchair)
It has strange uncommon electric motor and lead batteries...i think they are 24V. It has 7 gears but are not visible (probably hidden under that big disc). It can run with throttle only or with some kind of PAS. Front wheel is 20 inch.
Here are two pics of it (sorry for bad quality)
Batteries died and now he is looking for some options to update his handbike.
He is looking for about 25 kph top speed and he will not climb long steep hills just short modest climbs. Total weight of him + wheelchair + handbike is about 125 kg. He will mostly be ridding on PAS but would like to have option to simply switch to throttle only (is this possible?). We need to solve gears too...it has 135mm dropouts.
Battery:
He likes a battery from BMSB 36V 14.5Ah with integrated 18A controller with a rack (it also adds some weight on front wheel)

Motor: which motor would be most suitable? For 25 kph in 20 inch wheel we need about 260-270 rpm, right?
- Q100H 260 rpm with 7 speed freewhell
- Q128C 201 rpm(I read here it is actually 260 rpm...can anybody confirm this?) with 8 speed cassette
- Q128C 328 rpm (top speed of around 30 kph can be a little dangerous for quadriplegic in a wheelchair)
- Bafang CST 36V 350W 270 rpm with 8 speed cassette
We like Q128C the most but would really like to have 260 rpm.
What do you guys think?
Thanks
