Battery, range and storage

The supplier estimates 80–90 km with pedal assistance and specifies 8–9 hours for charging. Its approximate net weight is 43.18 kg, making lifting and storage access important parts of the decision.

Before you choose

Check the supplied motor edition and load limit with ortlux before purchase. The seat shape does not establish passenger capacity. Plan parking and storage around the actual dimensions rather than the wheel diameter alone.

Dimensions & weight

Manufacturer net weight: 43.18 kg
Maximum load: 90 kgCheck the manufacturer’s definition of total permitted load before carrying a rider and luggage. Passenger use is not implied.

Weight basis: Manufacturer net weight. Battery inclusion is not separately stated; packaged weight is excluded.

Range context: Manufacturer pedal-assist range estimate; not an ortlux road test. Rider mass, assistance level, terrain, temperature and tyre pressure affect the distance.

Configuration notes: Current W77 product page: 90 kg rider/cargo limit. Earlier source material differs. The battery is labelled 48 V / 18 Ah but also 648 Wh; 864 Wh is calculated from V × Ah. Confirm the supplied version before ordering. The supplier specification lists a 500 W motor, while the earlier web specification lists 250 W. The motor rating of the supplied edition requires confirmation; neither figure establishes public-road approval.

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.
