I think that the laws limiting top speed should be changed. Most any car is capable of 90+ mph speeds, but the speed is limited by the posted limits. Should we limit the maximum speed of cars to 65mph with gearing?
Maybe a motorized bike should be defined like this: "A motorized bicycle is a bicycle frame with a gasoline engine or electric motor attached. If an internal combustion engine is used, the piston displacement shall not exceed 50cc. If an electric motor is used, maximum output is limited to 1.5 kW. The system shall not require the operator to shift gears. The pedals must remain operational. The maximum speed a motorized bicycle is to be driven is 25 mph regardless of posted speed limits. Motorized bicycles must adhere to the same traffic laws as mopeds/motorcycles. No license or registration is required to operate a motorized bicycle. The minimum age to operate a motorized bicycle is 14. Any operator under the age of 17 is required to wear a bicycle helmet."
Here in NJ, it looks like a motorized bicycle is considered a moped and must be registered/insured. That's hogwash. It's these laws that killed the moped in the first place. Mopeds were a very common sight in the 70's and early 80's here in NJ. Don't see them much anymore because by the time you can ride a moped, it isn't long before you get your drivers license. Add to that the perception that mopeds are dangerous, and you have sales going down the toilet. (at least as a way for a young adult to get around)
