[determined]

Well I finaly built my first motorized bike but II have to admit im a little nervous about the whole thing .It runs good enough but the quality of some of the parts are cheap so im trying to do everything I can think of in order to make it safer.

Fixed geared bicycle? A true fixie pedals always moves in the direction of the rear wheel. A single speed uses a freewheel design which allows it to coast without the pedals moving.
