Description
The COSWHEEL Y20L Step-Thru Foldable Electric Bike combines practical commuter design with powerful performance for riders of all experience levels. Featuring a torque sensor system that delivers smooth, proportional power assistance as you pedal, this e-bike makes every ride more efficient, comfortable, and responsive than traditional sensor systems.
Powered by a 48 V brushless motor with up to 1200 W peak output (750 W rated) and 50 N·m torque, the Y20L reaches speeds up to 28 mph (45 km/h) and tackles inclines up to 30° with confidence. A removable 15 Ah lithium-ion battery delivers up to 52 miles (84 km) of range on combined throttle and pedal assist, so you can enjoy longer rides without worrying about recharging.
The step-thru frame design improves accessibility and comfort, while adjustable seat height and foldable frame and handlebars make storage and transport simple. At only 28 kg (≈62 lb), the Y20L is lightweight yet robust, ideal for daily commuting, errands, and recreational rides alike.
