Hi
Get in touch with the National Association of Disabled Bikers.
www.nabd.co.uk these guys will get you back on a bike in no time. They have designed adaptations for all sort of disabillities. Most of the adaptations are provided free through a grant scheme. Both my legs are fecked (from birth) and I have ridden for 27 years. I found out about the NABD last year joined (£20.00) applied for a grant a received a Kliktronic gear shifter plus a cheque to pay a local dealer to fit it. my riding has never been so good, I think so anyway ( I used to take my foot off and kick the lever down and hook my foot under the lever and lift my leg to change gear) I still need to lift my left leg on to the foot peg but now I have a push button system for the gears) if its your right leg get a thumb brake for the rear brake if its your left get a kliktronic. There is one lady member that lost both legs and rides a Hornet she has these staberlizers that come down as she slows down. The NABD also give grants towards the building of trikes.
