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.
