Little green is right make him walk for a while who should make you keep paying for new velkes so someone can make you pay $250.00 dollars when he breaks it let him walk for a while.He will probably be a little faster if he burns some of that off and he will be happy you made him do that after he burns that off.
How did he break it? I've had a single wheel velke on my machine for years now. The only problem I had with it was the plate got ripped apart from constant stopping and starting. I don't see how you can break one otherwise? And the plate is pretty easily replaced.
