You get a Shimano 7-speed drivetrain, mechanical dual disc brakes, and full suspension for a controlled ride. The removable 48V 13Ah battery, central LCD display, front and rear lights, and app and NFC support make it a practical choice for daily use. It folds down to 90 x 80 cm, weighs 31 kg, and can carry up to 150 kg, suiting riders from 5'2" to 6'1".

Your VARUN S20-2 PRO arrives 90% pre-assembled, so you can be on the road in no time. The box includes the e-bike, a charger, a tool kit and a user manual to help you finish the setup and keep your bike in top condition.

Fits riders from 5ft 2in to 6ft 1in
The adjustable saddle height ranges from 31.5 to 39.4 inches, while the frame height adjusts between 47.2 and 53.1 inches, so you can find a comfortable riding position whether you're commuting through London or exploring country lanes.

Unlock with NFC – no keys needed
Enjoy keyless convenience with NFC unlocking – just tap your smart card to start riding. The bike also offers three riding modes to suit your journey: pedal assist gives you a 50% power boost, pure pedal mode lets you ride unassisted, and walk mode helps you push the bike at 3.7 mph.
For even more flexibility, an optional throttle adds two extra modes: full electric mode powers you along without pedalling, and cruise control maintains a steady speed in electric mode once set.

Smart app control and real-time data
Stay connected on every ride with the intelligent app, which lets you monitor your speed, battery level, and distance in real time. The IP65-rated display is protected against rain and wind, so you can ride confidently in typical British weather.
