Thanks hadn't spotted that - it really should be on the front page. So it seems when he first put this kick-starter up he really had overlooked the obvious (despite having no brakes himself) or hoped everyone else would overlook it, until potential backers pointed out that it wasn't going to fly.

Now he has a bigger problem - his new system appears to work by wedging into the spokes where they converge at the rim, so he will need to supply the correct radius of strip for every size rim on the market.
