Hills Are A BEAST

All premium ebike manufacturers *should* be able to tick the box for battery range (it’s like all car companies putting airbags in cars), but that’s not the only factor…

Imagine finding a promising eBike. You get it home, charge up the battery, and head out...

Then like thousands of other riders out there, you discover the hills (and wind) aren’t any easier if the motor’s underpowered.

What good is an eBike if it can’t power up hills and over most terrain?

This Changes Everything

Previous generations of eBikes drew far too much inspiration from non-motorized bicycles. But an eBike isn't a bicycle with a missing motor. It's a whole new category.

And hill-climbing power didn’t exist — much less our Walk Assist Mode (useful when you have to hop off to climb ramps/stairs/obstacles vs. carrying your ebike).

But that’s all changed…And it’s where we got our head start 9 years ago. Seldom straightforward, but every prototype got us closer to optimum power (and fun).

That means more pedal assist power — most models feature 5 levels to balance range with battery usage so that you can top any hill or cruise through any headwind...

Shouldn’t Be A Complicated IKEA Project

A premium product should provide a premium setup experience.

Our bikes can be ready to ride in under 15 minutes after unboxing – ZERO technical expertise necessary!

Watch this video to see an example of the quick setup (using the Juggernaut Ultra Duo 3, but the process is essentially the same for every bike).

Then make your plans to explore the outdoors and conquer those hills.

With speed. With control. With comfort.
