Features

Hop On With Ease

Getting on and off your bike has never been easier, thanks to an accessible step through frame shape that also allows for a more comfortable, upright riding position.

Easy Access to Controls

The handlebar-mounted button pod controls everything, from the throttle, to the lights, to walk mode, pedal assistance, and more – all right at your fingertips.

On- or Off-Bike Charging

This ebike’s integrated battery can be charged both on and off the bike. LG 21700 cells enhance the battery capacity so it can store more energy and offer up to 52 miles of range when fully charged.

Off-Road Ready

Heavy-duty 26x4.0 fat tires offer stable, comfortable, and smooth rides on any terrain.

Quiet, Consistent, Confident Braking

Tektro mechanical disc brakes with upgraded semi-metallic pads & 180mm ebike-specific rotors offer reliable stopping power in any weather, so you can brake confidently.

Stay Seen, Stay Safe

Integrated front and rear lights with brake indicator illuminate your path and help improve your visibility while riding in low light.

Tackle Inclines or Cruise Flats

With a robust, versatile Shimano 7-speed drivetrain.
