Battery, range and storage

The supplier estimates 130–140 km with pedal assistance and a charging time of 6–8 hours. The torque sensor responds to pedal effort, but range still depends on assistance level, rider load, hills and temperature.

Why this brand is here.

ONESPORT’s range includes step-through city bicycles, folding models and fat-tyre configurations. OT05 and OT05 Pro focus on torque-sensing city riding; OT12 uses a simpler cadence-based system; OT16 models fold for storage, while OT08 variants use wider tyres. OT02 takes a smaller-wheel, single-speed approach.

ONESPORT covers step-through city bikes, folding formats and fat-tyre models. Start with storage space, rider fit and battery configuration. A folding hinge alone does not make a bike easy to carry; check the complete-bike weight before choosing it for stairs.
