The Kahuna is one of our best-selling hardtails. People love its simplicity and practicality. We brought that ethos to the El Kahuna and built a bike that was multipurpose-capable of riding the local singletrack for hours on end, and still have enough battery to go get the groceries on the way home. Its Shimano pedal-assist motor is powered by a semi-integrated battery and its 100mm fork provides just the right amount of suspension to absorb smaller hits on the trail. 29" wheels with 2.25" tires make this bike comfortable across all kinds of terrain. The El Kahuna the perfect all-rounder.
