Quick Summary
The VARUN S20-2 Pro is a versatile folding fat-tyre electric bike designed for commuting, leisure riding and mixed terrain. Featuring a strong aluminium-alloy folding frame, 20″ × 4.0″ fat tyres, full suspension and a 250W brushless motor, it combines everyday practicality with comfortable, confident performance.
Smooth Power Delivery
Equipped with a 250W brushless motor producing up to 55Nm of torque, the S20-2 Pro delivers smooth assistance for everyday riding and hillier routes. It comes factory-limited to 25 km/h (15.5 mph) and features a 5-level pedal-assist system with a cadence sensor, alongside Shimano 7-speed gearing for greater control over different terrain.
Comfort & Control
The 20″ × 4.0″ fat tyres provide excellent stability and cushioning across roads, tracks and uneven surfaces, while the full-suspension system uses front and rear suspension to improve ride comfort. Dual mechanical disc brakes provide dependable stopping performance, and the upgraded integrated mag wheels reduce the need for spoke maintenance.
Smart Battery System
Powered by a removable 48V 13Ah lithium-ion battery, the S20-2 Pro offers a manufacturer-stated range of approximately 70–120 km (43–75 miles), depending on assistance level, rider weight, terrain, weather and riding conditions. Charging takes approximately 4–5 hours, and the removable design allows the battery to be charged separately from the bike.
Tech You Can Trust
The upgraded colour LCD display provides essential riding information and supports app connectivity, NFC unlocking and Bluetooth locking. The bike also features an adaptive LED headlight and rear light for improved visibility, along with an IP65 water-resistance rating for added protection during everyday use.
Built for Everyday Use
Built around a durable aluminium-alloy folding frame, the S20-2 Pro supports a maximum total load of up to 150 kg (330 lbs). Its reinforced rear rack can support up to 50 kg, making it useful for carrying luggage and everyday essentials. The folding design also makes the bike more convenient for transport and compact storage.
Optional Throttle Support
The S20-2 Pro does not come with a throttle as standard. VARUN offers compatible thumb-throttle and twist-throttle options separately. Riders should always check local regulations before using a throttle or changing the bike's factory speed settings on public roads.
