Who says you have to compromise? The ENGWE O20 Boost refuses to choose between comfort, power, and portability — delivering all three in one genuinely versatile folding e-bike. Comfortable enough for the daily commute, powerful enough for city slopes and longer weekend rides, and portable enough to fold into your hallway or your car boot. One bike, built for riders who want more.

Boost power that moves you

At the heart of the O20 Boost is a UK-legal 250W hub motor with a Boost function, delivering a punchy 75 N·m of torque — strong enough for quick, confident acceleration and easy climbing. Cruise through the city with noticeably less effort, take on slopes without breaking stride, and arrive fresh even after a longer commute. It's everyday power that genuinely changes how your ride feels.

Natural assistance from a torque sensor

A responsive torque sensor reads your pedalling force in real time and delivers smooth, natural support that adapts to your effort — never jerky, never lagging. The result is intuitive, proportional power that feels like an extension of your own legs, whether you're pulling away at the lights or settling into a steady cruise.

Go farther, charge less: 720Wh LG battery

Range anxiety, banished. The O20 Boost is powered by a high-capacity 720Wh battery built with 21700 LG cells and a smart BMS (Battery Management System) for advanced protection and longevity. ENGWE quotes up to 140 km of range, with real-world tested figures of 141 km in the lowest assist level, 108 km in mid-assist, and 80 km in the highest — so even hard-charging riders get genuinely usable distance between charges.

3.5-hour fast charging

Less waiting, more riding. The included 4A fast charger powers the battery up in around 3.5 hours — and the system even supports 8A charging with an optional charger for an even quicker turnaround. Spend your time riding, not waiting at the wall.

Next-level riding comfort

This is where the O20 Boost stands apart from typical folders. A hydraulic front suspension fork with 50mm of travel and adjustable lockout absorbs bumps and uneven roads — ENGWE claims up to a 70% reduction in impact — then locks out for efficiency on smooth tarmac. Paired with wide 20" × 2.125" anti-puncture urban hybrid tyres, it delivers extra stability and cushioning for a genuinely smooth, planted ride wherever you go.

Reliable Shimano gearing

Beyond the electric assist, a proper Shimano Altus 8-speed drivetrain gives you smooth, reliable mechanical gears for tackling different terrains and speeds — a real bike at its core, not just a motor and a battery.

Fold fast, park with ease

Designed for real life, the O20 Boost features a one-hand folding design for easy storage and transport, plus a foldable stem and pedals to make the package even more compact. A clever twin-leg centre kickstand keeps it stable and secure when parked. Compact enough to fit two bikes in a car boot — perfect for couples riding together, or simply slotting into your everyday life.

Smart, secure, and beautifully equipped

A bright, mid-mounted 3.5" colour LCD display (ENGWE-designed, with Bluetooth) keeps all your ride data clear at a glance, and connects to the ENGWE App for app control. For security, a built-in hidden slot houses a "Find My"-compatible tracker (iOS and Android), giving you extra anti-theft peace of mind. Hydraulic dual-piston disc brakes with 160mm rotors front and rear deliver strong, consistent stopping in all conditions, while K-Mark certified, road-legal front and rear lights keep you visible and legal after dark.

City or beyond — all in one

Effortless for daily commuting, capable for weekend adventures, and portable enough to take anywhere — the ENGWE O20 Boost is the folding e-bike without limits. More comfort, more power, more capability. No compromise.
