Step-through comfort with compact storage
The ENGWE O20 Boost combines a low step-through frame with 20-inch urban tyres and a folding design for storage between rides. A torque sensor controls its 250W hub motor, while the Boost function provides up to 75 Nm for extra support when pedalling uphill.
Its removable 720Wh LG-cell battery pairs with a 4A charger, while Shimano Altus eight-speed gearing lets you adjust your pedalling to the route. A 50mm suspension fork, hydraulic disc brakes, lights, mudguards and a rear rack provide a practical setup for daily journeys.
