Kākau Go! is an homage to the islands that make up Polynesia, the birthplace of surf. The Matte Ember frame, reminiscent of lava rock that can be found throughout the islands, is complimented by a tribal pattern inspired by the traditional tattoo art form, known as Kākau. A wood grain underlay throughout represents the Koa tree and wood used for early surfboards. Custom grips, saddle and bell complete this awesome e-bike.
- Features a step-over frame with our patented Flat Foot Technology® for ultimate comfort and control.
- Reach a top-assisted speed of 20 mph with support from the rear hub motor.
- Monitor your level of power support and battery charge easily with the LED controller.
- Custom embossed saddle, grips and matching bell make this e-bike as unique as you.
