Sprinta 858 Air Bike

Sprinta 858 runs a 24 kg flywheel on a belt drive — quiet enough to hold a conversation over, heavy enough that the pedal stroke stays round.

Pedals take standard 9/16″ threads, so clipless pedals go straight on. Maximum user weight 130 kg; the frame is tested well beyond that.

Powder-Coated Steel, with a belt drive that needs no tensioning between services. Q-factor is 170 mm, close enough to a road bike that it does not retrain your hips. Nothing about it is glued shut, so a worn bushing stays a ten-minute job.

Care

Check the pedal threads monthly — a loose pedal ruins a crank in one ride.
