Battery, range and storage

The supplier estimates 80–100 km in pedal-assist mode and specifies 7–8 hours for charging. These figures describe the documented configuration; actual range varies with temperature, route and rider load. The frame is not folding.

Before you choose

Check your storage space and lifting needs against the approximately 39 kg manufacturer net weight. A long saddle does not establish passenger permission: check the vehicle instructions and the applicable load definition.

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.
