My electric scooter uses regeneration for braking. If you take your hand off the throttle it stops right now - I'm surprised it does'nt have a seat belt... The controller also limits coasting speed to 5 mph. I can take the bus to the shopping center, circa 3 miles, 700 foot elevation gain (GPS), then coast back, arriving home with an apparently fully charged battery.
