The VOLTREX KAHUNA is a full-sized fat-tyre electric bike built for riders who want more room, greater stability and a confident ride across a range of surfaces.
With large 26 × 4-inch tyres, KAHUNA delivers a planted feel on sealed paths, gravel and rougher terrain. Adjustable front suspension helps absorb bumps, while the larger frame and upright riding position provide a comfortable fit for taller riders or anyone who prefers a more substantial bike.
A 250W BAFANG rear hub motor provides smooth pedal assistance up to 25km/h, with 6km/h walk/start assist for low-speed manoeuvring. The integrated 15Ah removable battery keeps the frame clean and balanced while providing up to 55km of range depending on riding conditions.
KAHUNA also includes a wide comfort saddle, front and rear mudguards, a large LED headlight and heavy-duty rear rack for carrying additional gear.
