Don't get me wrong though! I think the QT50 is the best of the best. There is no other moped/scooter that was so well thought out! Every detail has been thought of and corrected. I could go on and on about the superior design of this moped but you would never realize it until you took one apart or sized it up against a competitor. The simple fact it uses a drive shaft with a ring gear similar to a BMW motor bike is reason enough. This bike goes thru dirt, muck and grime and is totally sealed. Period. This drivetrain has been in use for over 20 years and is still the top competitor in PeeWee racing. If you thought that was funny your an IDIOT. This is a serious machine/setup and can run with the best of them! The only downfall is brakes and this is the worst problem on all mopeds/scooters.
