This Voilamart front hub kit puts a 500W peak brushless motor in the front wheel, making it easy to fit to bikes with derailleur gearing at the rear since nothing changes at the back wheel. With 48V power and a full twist throttle, it delivers brisk throttle-on-demand acceleration. Because it exceeds 250W and has a hand throttle, this kit is not within EAPC limits. For off-road / private land use only – not road-legal in the UK. Do not ride on public roads, cycle paths or bridleways. Supplied with the front motor wheel, LCD display, brake cut-off levers, controller, twist throttle and wiring. Choose your wheel size at order. Note: front hub kits are best on frames with strong, undamaged forks.

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.
