All bikes come with a battery that you can easily charge with any standard 110v outlet. On this model, the battery is removable with a key, making it easy to charge both at home and in-between rides.

*Battery range estimates depend on conditions such as rider weight, speed, temperature, wind, tire pressure, terrain, incline, etc. Mileage may vary. All bikes are subject to minor cosmetic changes. We only ship within the Continental US and final shipping costs will be calculated at checkout.
