Greetings to all:
I am interested in buying, building or modify a bike for my 2 1/2 year old son who has spinal muscular atrophy. At this point I just want something he can sit on with some upper body support (chair type) and for him to pedal with very low resistance.
Longer term I want sensors in the pedals to detect level of effort and relay the detected effort to a small motor to assist with propulsion.
My son is intellectually fully functional. He has weak legs, trunk and arms. He is being provided physical and occupational therapy. We are encouraged to keep him active without exhausting him.
