Paul W.

“I wasn't sure which ebike I wanted, but the guy at Ebike Generation helped me understand each of the models, the different frame designs, and how the different batteries. I ended up choosing the Jetty, and I'm real pleased with it so far. I think I want to get a second battery, because i don't want to wait for it to recharge every time. But that's so minor. Thanks again.”

FREQUENTLY ASKED QUESTIONS

Need more info? You can find it here.

How do ebikes work?

Ebikes work by combining a traditional bicycle design with an electric motor and battery. When the rider pedals, a sensor detects the motion and activates the motor, which provides additional power. Riders can adjust the assistance level from low boost to high support for hills or long distances.

Can you pedal an ebike without the motor?

Yes! Ebikes can be pedaled like regular bikes. You can turn off the motor completely or use any pedal assist level depending on how much help you want.

How far can an ebike travel on a single charge?

Most ebikes can travel between 25 and 70 miles on one charge, depending on battery size, terrain, weight, and assist level.

Are there different types of ebikes available?

Yes. Popular types include mountain ebikes, city/commuter ebikes, folding ebikes, cargo ebikes, and more. Each is designed for different riding styles and terrains.

Do I need a license to ride an ebike?

In most regions, ebikes that meet speed and motor power limits are treated like regular bicycles and do not require a license. Check your local ebike laws to be sure.

How do you maintain an ebike?

Maintaining an ebike is similar to caring for a regular bike: keep the battery charged, check tire pressure, lubricate the chain, test brakes, and inspect electrical connections regularly.
