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) battery with LG cells gives a range of up to 140 km, a 50mm travel front 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 Bike-to-Work scheme eligible. Available from Inner City Scooters in Dublin, Ireland.
A Folding E-Bike Without Limits
Why Should You Have to Compromise?
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 — full-size ride quality in a frame that folds away.
Comfort, Power and Range in a Folding Design
Front suspension, high torque and a long-range battery come together in a compact frame that still fits your hallway, your lift and your car boot.
City or Beyond — All in One
Comfortable, Powerful, Portable
Comfortable enough for the daily commute thanks to front suspension. Powerful enough for city slopes, hills and longer rides with high torque and a long-range battery. Portable enough to fold down and fit into everyday life.
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, while 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 / 25 km/h limits.
Go Farther, Charge Less
720Wh LG Battery, Up to 140 km
Powered by a 48V 15Ah (720Wh) battery built from 21700 LG cells with BMS protection — tested at 141 km on PAS 1, 108 km on PAS 3 and 80 km on PAS 5 for worry-free daily riding.
3.5h Fast Charging, Less Waiting
The included 54.6V 4A fast charger powers the battery back up in just 3.5 hours. More riding, less downtime — and 8A charging is supported with the optional charger for an even quicker turnaround.
Fold Fast, Park with Ease
One-Handed Fold, Twin-Leg Kickstand
Quick, easy folding ready in seconds with one hand, folding down to 88 x 52.5 x 85cm. 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.

FAQ about the Engwe O20 Boost
Is the Engwe O20 Boost road-legal in Ireland?
Yes. With a 250W motor, torque-sensor pedal-assist and assistance cutting off at 25 km/h, the O20 Boost meets the EU pedelec (EPAC) standard and is treated like a bicycle in Ireland — no tax, insurance or licence required — when ridden in pedal-assist. It also carries K-Mark certified lights for legal night riding. Always wear a helmet and use lights after dark.
Is the O20 Boost eligible for the Bike-to-Work scheme?
Yes. As a road-legal pedelec, the O20 Boost is eligible for Ireland's Cycle to Work / Bike-to-Work scheme, letting you save through your employer (tax-free, repaid from gross salary). Ask your employer to set up the purchase with us and we will provide the invoice you need.
What is the real-world range?
The O20 Boost is rated up to 140 km, tested at 141 km on the lowest assist (PAS 1), 108 km on PAS 3 and 80 km on the highest assist (PAS 5). In real-world Irish riding — hills, rider weight, weather and assist level — expect roughly 60–110 km per charge.
How long does it take to charge?
The 720Wh battery charges in about 3.5 hours with the included 54.6V 4A fast charger. It also supports 8A charging with the optional charger for an even quicker turnaround.

How much does it weigh and does it really fold?
It weighs 26.5 kg and folds one-handed in seconds down to 88 x 52.5 x 85 cm — compact enough for a car boot, hallway or lift, and easy to fit two in the boot for trips away.
