Hopefully the biker wont give up riding. I met a guy this weekend who outfitted his bike (GSXR1000)for about $3000 to function for him. He was paralyzed from the waist down in a motorcycle accident.
He had what looked like training wheels on his bike which stabalized it when it was at a stop, but would go up and out of the way with a switch. his handlebars were outfitted with push buttons for shifting (co2 enabled), and his legs were strapped onto the side of the bike. anything can be done!
glad the cop got his, we will see how long he lasts in jail.
