Engwe O20 Boost Folding Electric Bike
The Engwe O20 Boost is a compact folding electric bike built to remove the usual trade-off between portability and real riding performance. A 250W 48V hub motor with Boost Function delivers 75Nm of torque, driven by a torque sensor that reads your pedalling effort for natural, EU-legal pedal assist up to 25 km/h. A 720Wh (48V 15Ah) LG-cell battery gives up to 140 km of range, a 50mm hydraulic fork and 20" anti-puncture tyres smooth out city roads, and the 6061 aluminium step-through frame folds one-handed in seconds. Fully road-legal in Ireland and Cycle to Work scheme eligible — available now from Inner City Scooters, Dublin.
A Folding E-Bike Without Limits
Full-size comfort. Foldable freedom. Traditional bikes give you comfort and power; folding bikes give you convenience and portability. The O20 Boost is built to give you both at once.
Comfort, Power and Range in a Folding Design
Front suspension, 75Nm of torque and a 720Wh battery in a compact frame that still fits your hallway, your lift and your car boot.
Who Says You Have to Compromise?
Most folding bikes ask you to give something up — range, comfort or power. The O20 Boost was designed to keep all three.
City or Beyond — All In One
City Ride
Effortless for daily commuting, with front suspension taking the sting out of Dublin kerbs, cobbles and broken tarmac.
Weekend Ride
Capable for longer weekend rides — high torque and a long-range battery handle hills, headwinds and gravel paths.
Everyday Use
Portable enough to fit into your everyday life and your boot, thanks to the one-handed folding design.
Next-Level Riding Comfort
50mm Suspension — Bumps Cut by up to 70%
A hydraulic front fork with adjustable lockout absorbs kerbs, cobbles and broken tarmac. Lock it out for smooth tarmac and get every watt into forward motion. 20" x 2.125" anti-puncture urban hybrid tyres add extra stability and cushioning.
75Nm Power That Moves You
Boost Mode, 75Nm Torque, 250W Motor
Strong torque for quick acceleration and easy climbing, so you cruise through the city with less effort and stay fresh even on longer commutes — all within the EU-legal 250W rated / 25 km/h limits.
How Boost Mode works
- Mode Boost — a short surge of extra torque on demand
- Torque 75Nm peak, for hill starts and pulling away at lights
- Motor 250W rated 48V rear hub, EU pedelec compliant
- Sensor Torque sensor reads how hard you pedal, not just that you are pedalling
- Assist 5 levels, selectable from the colour display
- Cut-off Assistance stops at 25 km/h, as required in Ireland and the EU
Go Farther, Charge Less
720Wh LG Battery, Up to 140 km
A 48V 15Ah (720Wh) pack built from 21700 LG cells with BMS protection. Engwe's own testing returned 141 km on PAS 1, 108 km on PAS 3 and 80 km on PAS 5.
3.5h Fast Charging — Less Waiting
The included 54.6V 4A fast charger refills the battery in about 3.5 hours. 8A charging is supported with the optional charger for an even quicker turnaround.
Fold Fast, Park With Ease
One-Handed Fold, Twin-Leg Kickstand
Folding is quick and easy — ready in seconds with one hand, down to 88 x 52.5 x 85 cm. A centre-mounted twin-leg kickstand keeps it stable and upright when parked.
4 + 2, Made for More
Perfect for couples riding together and easy to take along in the car — compact enough to fit two folded bikes in the boot, built for both daily use and weekend getaways.
