This Bike Is Not Road Legal. Private Land Use Only.
This bike cannot be ridden on public roads, pavements, or cycle paths in the UK. Its motor output and assisted top speed exceed the legal limits set by the UK Electrically Assisted Pedal Cycle (EAPC) regulations, which cap electric bikes at 250W motor power and 15.5 mph (25 km/h). Because this bike exceeds both thresholds, it is classified as a motor vehicle and would require registration, insurance, and a valid licence to use on public roads. This bike is designed exclusively for use on private land such as farms, estates, and off-road tracks where road traffic law does not apply.
See UK LegislationCompact e-bike for city life
The Varun S20-1 is built for riders who want a nimble, easy-to-store electric bike that handles daily commutes and weekend rides with confidence. Its 20-inch wheels make it agile in traffic and simple to tuck away in a hallway or car boot. With a 500W motor and fat tyres, it delivers a smooth, stable ride on UK streets and light trails.
Powerful motor with hill-climbing torque
Climb steep hills without breaking a sweat thanks to the 500W motor and 80 Nm of torque. The motor responds smoothly to your pedalling, delivering full power from 70 rpm and holding it past 100 rpm, so you keep momentum on long climbs. It runs quietly, letting you enjoy the ride without motor whine.
Long-range battery for extended rides
The 48V 13Ah battery gives you up to 35 miles of pure electric range, so you can cover most commutes and errands on a single charge. Recharge in 4–6 hours with the fast charger, and use regenerative braking to recover a little energy on descents. The battery is removable for convenient charging at home or work.
Comfortable ride with fat tyres and suspension
20-inch by 4-inch fat tyres soak up bumps and provide excellent grip on wet or uneven roads. The unique suspension front fork smooths out potholes and kerbs, reducing fatigue on longer rides. The aluminium frame keeps the bike responsive while supporting riders up to 331 lbs.
Confident stopping power in all weather
Dual disc brakes give you reliable, controlled stopping even in rain or on steep descents. Regenerative braking helps slow you down while feeding a small amount of energy back into the battery. The IP65 waterproof rating means you can ride through puddles without worrying about the electrics.
Clear display and simple controls
The LCD display shows your speed, battery level, and assist mode at a glance, so you always know how far you can go. Controls are within easy reach, letting you switch assist levels without taking your eyes off the road. A headlight and mechanical horn are included for safer riding in traffic and low light.
Easy assembly and everyday practicality
The Varun S20-1 arrives 95% assembled, so you can be riding within minutes of unboxing. The step-through frame makes mounting easy, and the 7-speed Shimano transmission gives you the right gear for any situation. Available in black or grey, it fits riders from 150 cm to 180 cm tall.
