Hi to all. I own 5 Whizzers and just purchased my 6th, a Whizzer Ambassador II. I was wondering if anyone has one of these and, if so, have they had a problem with the belt cover vibrating so much that it winds up cracking [it's made out of chromed plastic] and breaking into 2 pieces? I'm on my second one and I know that it will happen again because the front half of it isn't supported at all to the bike. Thanks for any feedback.
