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. The 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 BAFANG rear hub motor provides smooth assistance, while the integrated removable battery keeps the frame clean and balanced. KAHUNA also includes a wide comfort saddle, front and rear mudguards, a large LED headlight and a heavy-duty rear rack for carrying additional gear.
