This is my first EV and basicly built as a experiment.
The mini bike has been a great place to start.I learned how to fry a controller,how to smoke a motor and how to do some ev math. The 25 mph top speed is fine for the side streets and on shuch a small bike it feels like your flying. Idealy I like the idea of a electric scooter (vespa kind of thing) with a top speed of 40-45 mph with a range around 15-20 miles. Next comes a custom built frame with real suspenion, bigger motor and bigger batteries.
