Onesport OT12 review
Onesport OT12 review based on published specifications: 36V 13Ah battery, weight definitions, regional motor claims and practical ownership checks.
Product evidence checked 7 October 2026
Our assessment
The OT12 gives unusually useful weight definitions: 27.8kg without accessories, 34kg with them, and a 120kg permissible total including the bike. Using the equipped figure leaves only 86kg for rider and luggage, subject to the manufacturer’s final definition.

What stands out
- Published battery information: 36V 13Ah
- Model-specific source and weight evidence: Net weight: 27.8 kg (excluding all accessories) Full weight: 34 kg (including all accessories) Permissible Max. Weight: 120 kg (including the bike's own weight)
Limitations and unknowns
- Catalogue range and performance have not been independently measured.
- The supplied regional configuration and proprietary spare-parts support need written confirmation.
Battery and range: what the figures mean
The Onesport OT12 battery is listed as 36V 13Ah. Multiplying nominal voltage by amp-hours gives approximately 468Wh of stored energy; this is a calculation from the catalogue, not a usable-capacity measurement. Reserve energy for cold conditions, hills and an ageing pack rather than designing a journey around the headline maximum.
Weight, storage and equipment
The published Onesport OT12 weight entry is Net weight: 27.8 kg (excluding all accessories) Full weight: 34 kg (including all accessories) Permissible Max. Weight: 120 kg (including the bike's own weight). Read the definition carefully: a shipping figure, accessory-excluded net weight and complete-bike weight answer different questions. For practical ownership, check the mass you will actually lift with the battery, rack and daily equipment installed, and try that lift before deciding on upstairs storage.
The Onesport OT12 lists 27.5*1.65 pneumatic rode tyre tyres. Check replacement availability using the tyre’s ETRTO marking rather than a nominal inch size alone. The published frame or fork entry is Steel; this identifies equipment, but does not demonstrate damping quality, steering behaviour or braking distance.
Regional specification and British road use
The Onesport OT12 catalogue needs to be checked against the exact supplied regional version. For ordinary EAPC treatment in Great Britain, the continuous rated motor output must not exceed 250W and assistance must cut off at 15.5mph, alongside the other pedal-cycle requirements. Obtain the motor marking, controller specification and throttle documentation; a peak-power number alone does not decide the category.
Support and the checks before ordering
For the Onesport OT12, obtain a model-specific replacement-battery quote, the charger part number and an identified warranty contact before ordering. Confirm whether the seller supplies spare displays, controllers and motor connectors for this exact generation. Ordinary cycle components may be serviceable locally while proprietary electrical parts still depend on the original supplier.
