-The Next Web
A great ebike for getting around, especially if you live in a mountain town!
find your perfect fit
One of the benefits of an ebike is that you don’t need to focus on getting the exact-right size to maximize pedaling efficiency - the motor is plenty efficient for you!
- Stellar Series models come in two sizes that should comfortably fit most people. You'll still want to choose the one that’s best for you!
- Utility Family models all have a lower stepover and fit most riders between 4'9" and 6'4"
We recommend you compare your inseam measurement, taken wearing shoes you are likely to ride in, to the stand-over height of our various models. As long as you've got around 1" of clearance over the top tube you'll likely be good to go! If you're on the cusp between sizes we generally recommend sizing up. Don't hesitate to reach out if you've got any sizing questions!
