I ride for miles and battery never seems to go down. Took only a few minutes to learn how to use. It's built very sturdy and I'm having fun. I also bought a little air horn to honk so people move out of my way....
This is a good unit but you need to be aware that the manual is NOT current. There is a sequence in which you need to use the charger or your $500.00 battery will only last about 18 months. First plug it into the unit, THEN plug it into power. If you do not follow this order than you will have a rather large expense in 18 months replacing the battery.
