Many suppliers are probably going out of business because many states are outlawing motorized bikes. What was originally an idea to make it easy to get around without using a car/truck has gone completely wacko. 9 out of 10 MB riders are breaking the law, many in several different ways at the same time. Reckless riding, and especially speeding are giving legislators a lot of ammunition to justify getting rid of motorized bike laws. Car drivers, pedestrians, and pedal bike riders all consider them a nuisance, and in many cases downright dangerous. I canceled my plans to build a new bike because I keep hearing bad news about MB riders and laws in the news. We have a very strong anti MB lobby, and they will eventually win. And things like gt6 pro racing kits are to blame. MB laws do not allow racing bikes. Riders flaunt the law with impunity. What was intended as a low cost means of transportation has gotten completely out of control.
