I notice the description for this area of Bike Forum says, "This area is for discussion among those of us in the cycling world that are coming back from traumatic circumstances..."
I think that description should be expanded to include ALL people with disabilities. Moving on...
My son is 12 and has autism. And he loves bikes. But until recently he could not/would not ride a two-wheeler on his own. A couple weeks ago we bought him a new bike. It's a bike unlike any other that we, as his parents, had seen. It's the Jamis Hudson. What makes this particular bike just right for my son? Two things;
1. It has a single brake lever that controls both front and rear brakes, putting most of the stopping power into the rear. That means there's no danger of him pulling the wrong lever and flying over the handlebars.
2. The shifting all takes place in the rear hub. That drastically simplifies shifting. Most bikes, as you know, have to be moving and you have to be pedaling when you shift gears. Not with the Jamis Hudson.
Just thought I'd share that. :-)
