350W Pedal Assistance

Torque sensing with four levels of support.

352.8Wh Removable Battery

Electric Support That Follows Your Effort

A torque sensor responds to your pedaling, supported by a 350W rated rear hub motor with 500W listed peak output and 45Nm maximum torque. Four assistance levels let you choose the support for your route. This configuration has no throttle.

Shimano ACERA eight-speed shifting gives you mechanical gears alongside electric assistance. The listed default assisted speed is 20 mph, with a 28 mph unlock option; confirm the supplied settings and where they may be used.

Charge the Battery. Keep Your Routine.

A removable Samsung 36V 9.8Ah battery provides 352.8Wh of nominal energy. The battery sits within the downtube and can be removed for charging. Listed charging time is approximately 2.5 hours with the supplied 36V 4A charger. No external range extender is listed.

The stated range of up to 81 miles was tested with a 180 lb rider in ECO mode on flat roads using pedal assistance. Your distance will vary with terrain, speed, temperature, rider load and assist level. Plan a reserve for the return journey.

A Distinctive Carbon Frame, Sized for You

The sculpted carbon-fiber frame and rigid carbon fork form a full-size step-over commuter bike. Choose Matte Black or Cream, then select Small, Medium or Large using the fit measurements below. The frame does not fold and does not use suspension.

A 720mm handlebar, ergonomic locking grips and stem-height settings of 0, 15 or 30mm help refine your riding position. Confirm included accessories for the selected configuration.
