now to be honest and i alway am, its a 75 year old guy. he rides a 36v 250 rear folding bike. he keeped asking me to get him a spair bike. i found him one road once, 24v 250w front wheel. he loved it but now want me to change it to a 36v rear as its not got enough power and he doesn't fell safe with the front wheel. to be honest it will be a pain as the rear wheel has a drum brake so i'll have to make and fit i rear break.
but now he's come today and asked could i build a one fro his friend again folding 20 inch rear. as he would rather i got a good quality bike and put the kit on for him (batteries arnt an issue) problem is the only kits i can find is china, the price is ok but its the wait. ive had a few kits from electricbikeconversions, but for some reason there numbers not working.
so i though someone may now of some kits out there but has to be rear wheel.
