A fair criticism. I'm working on it. If all your bikes run 700c wheels, I've already got that worked out. I can move my dynamo front wheel from bike to bike. I'm working on making the lights detachable, too.

One really cool option is to attach the headlight to the front wheel, but that's quite tricky and not necessarily going to work on just any bike. Sheldon managed it.
