Bafang BBS02B 500W mid-drive kit pre-fitted for wide 100mm fat-bike bottom brackets, with full throttle. For off-road / private land use only — not road-legal in the UK.
This VOLTARC-assembled kit pairs the proven Bafang BBS02B 48V 500W mid-drive motor with a 100mm bottom-bracket spacer set, making it a direct fit for fat bikes and wide-BB frames where the standard 68/73mm unit will not seat correctly. It delivers 100Nm through your drivetrain for confident climbing across sand, snow and loose trails, with both pedal-assist and a full hand/thumb throttle. Includes the BBS02B motor, 100mm spacer kit, lockring spanner, chainring, motor-cut-off brake levers, gear sensor, colour display, PAS sensor and full wiring loom. For off-road / private land use only — not road-legal in the UK. Its 500W rating and full throttle exceed the UK EAPC limits, so use is restricted to private land or off-road with permission.
This machine is fitted with a full twist-grip throttle and is not compliant with UK EAPC (Electrically Assisted Pedal Cycle) regulations. It must only be used on private land or a closed circuit with the landowner’s permission. Using it on a public road, cycle path or other public place would require type approval, registration, tax, insurance and a relevant licence.
Riders are responsible for using appropriate protective equipment and complying with local rules.

No. EAPC (Electrically Assisted Pedal Cycle) e-bikes are legal on UK roads without a licence, insurance, or registration, provided the motor assists only while pedalling and is limited to 250 W / 15.5 mph.
Range depends on the battery size, rider weight, terrain, and assist level. Check the specific product specification for its stated range; typical figures are 40–120 miles per charge.
Most batteries charge in 3–6 hours from flat using the supplied charger. Fast-charge options (where available) can halve this time.
Yes. Our bikes carry an IP rating (see spec tab) and are designed for UK weather. Avoid submerging the battery or motor. Dry and lightly oil the drivetrain after wet rides.
