Ride up to 20 MPH with the 250-watt brushless geared hub drive pedal assist motor that gives you a boost while you pedal. Choose from several levels of assistance or use the throttle instead.

Charge Up & Ride

Go 45* miles on a single charge, depending on conditions with the 360-watt hour internal downtube battery with 21700 cells. Recharge in 5 hours with a standard household outlet and included charging cable. *Varies based on terrain, pedal usage and assist level.

Light the Way

Integrated LED lights on the battery add to the sleek, modern look while helping others to see you on low light rides. Head and taillights are also included for improved see and be-seen visibility.

Take it With You

The rear rack offers plenty of cargo space for backpacks or picnic baskets, while under-seat storage compartment is great for your keys, wallet, and other small items.
