VARUN S20-2 PRO Folding Electric Bike | 250W EAPC Specification | 624Wh Battery | Full Suspension | NFC Display

Discover the VARUN S20-2 PRO Folding Electric Bike, featuring a 250W brushless motor, removable 48V 13Ah lithium-ion battery, 20 x 4.0-inch fat tyres and a folding aluminium alloy frame. Designed for recreational cycling and outdoor exploration on suitable surfaces, the S20-2 PRO combines full suspension, Shimano 7-speed gearing and a smart colour display with NFC unlocking.

The manufacturer-listed 250W brushless motor produces 55Nm of torque. A cadence sensor detects pedalling activity, while five selectable pedal-assist levels allow riders to adjust electrical support. The standard European configuration is advertised with assistance limited to 25km/h (15.5mph).

The removable 48V 13Ah battery provides 624Wh of nominal energy capacity. VARUN advertises a pedal-assisted range of approximately 70–120km, depending on operating conditions. Actual range varies with assistance level, rider weight, terrain, temperature, tyre pressure, and battery condition. The manufacturer lists an estimated charging time of 4–5 hours.

The S20-2 PRO features full suspension, combining a lockable front suspension fork with a rear shock absorber. This arrangement helps reduce vibration and absorb impacts on appropriate uneven surfaces. Its 20 x 4.0-inch fat tyres provide a wide contact patch and additional cushioning when correctly inflated.

The Shimano 7-speed drivetrain provides mechanical gear selection for varying gradients, while front and rear mechanical disc brakes offer controlled stopping performance when correctly adjusted and maintained. The aluminium alloy frame supports a manufacturer-listed maximum combined load of 150kg.

An upgraded colour LCD supports NFC unlocking, Bluetooth, and compatible phone-app functions. The manufacturer also lists integrated mag-style wheels, LED front and rear lights, and a heavy-duty rear rack with a maximum rated load of 50kg, subject to the bicycle's overall load limit.

The S20-2 PRO is offered in Black, Orange and White. Optional thumb and twist throttle accessories are advertised separately and should not be assumed to be included with the standard European configuration.

Off-Road Compliance Notice

UK EAPC Classification: VARUN advertises the standard European S20-2 PRO as a 250W electrically assisted pedal bicycle with assistance limited to 25km/h (15.5mph). The manufacturer lists CE certification to EN 15194 and separately advertises UKCA certification.

UK Electrically Assisted Pedal Cycle classification requires maximum continuous rated motor power not exceeding 250W, electric assistance that cuts off at 25km/h, functioning pedals, and compliance with all other applicable requirements. The supplied bicycle must match the manufacturer's approved configuration and supporting documentation.

Factory Speed Settings: VARUN advertises adjustable assistance-speed settings. Changing the factory restriction may invalidate EAPC classification, even if the motor is advertised as 250W.

Optional Throttle Accessories: The manufacturer offers optional thumb and twist throttles. Throttle installation and operation must be assessed against applicable UK requirements. Do not assume a modified configuration retains standard EAPC status.

Higher-Power or Non-Conforming Configurations: A configuration exceeding 250W maximum continuous rated motor output, or otherwise failing EAPC requirements, must not be assumed to be permitted on public roads or other publicly accessible areas. Additional approval, registration, insurance or licensing requirements may apply.

Private Land Use Where Required: Where a configuration is not legally authorised for public use, operation should be restricted to suitable private land with the landowner's permission or other locations where the configuration is legally permitted.

Recreational Access: Even an EAPC-compliant bicycle may be used only where cycling is permitted. Follow local access rules, manufacturer instructions, and recommended safety precautions.
