E-Bikes

What are e-Bikes?

Electric bicycles, or e-Bikes, provide riders with a speed boost through an electric motor of 750 watts or less. Support from these motors helps riders bike greater distances, up steeper inclines, and with heavier loads–making it easier for everyone to get around, especially people who may need more support due to age, ability level, and more.

Types of e-Bikes

e-Bikes are generally classified based on their maximum speed and how they give you power. Depending on the type of e-Bike you use, different rules apply. Other electric modes of transportation, like low power scooters and electric motorcycles, have their own rules and restrictions.
