looking for a type or maybe just experience from someone who has to work through this issue.

i saw a bike at my local co-op that has had me kicking around the idea of building a bike for a nephew with only his left hand. kinda foot forward, aluminum frame (cruiser style though, so not the lightest, but hopefully not too much wrass'lin) 24" 'cause he's not real tall. in my mind it just seems like something he could ride comfortably.

a lock is the one thing i can' mentally work out. maybe for him, and those of you who deal with this, it may be something more easily worked through from the experience of only having one hand to work with. more precisely, he lost his right arm a few inches past the elbow, so i guess he could hold an end in the crook of his elbow? i don't know. i guess i could just ask him these things, but i'm really not around him much or see him very often.

ok... switched to rambling. any insight appreciated. thanks.
