COSWHEEL Y20L Folding Electric City Bike 250W – Review and Comparison

The COSWHEEL Y20L is a folding electric bike with an open frame, specially designed for effortless urban commutes and daily journeys. Thanks to its 250W brushless rear motor and 75 Nm torque sensor, it offers smooth and natural pedal assistance, suitable for all cyclists, including older people and those with reduced mobility. Its removable 48V 15Ah battery (720 Wh) provides an exceptional range of up to 150 km per charge (in pedal-assist + throttle mode), ideal for long commutes or city travel.

The Y20L stands out with its hydroformed 6061-T6 aluminium alloy frame with triple variable thickness, both lightweight and durable, and its folding design (frame and handlebars) for easy transport and storage. Weighing 36 kg (with battery), it remains manageable despite its robustness. Its lockable front suspension (80 mm travel) effectively absorbs shocks, while its front and rear 160 mm stainless steel disc brakes ensure powerful and progressive braking in all conditions.

For comfort, the Y20L features height-adjustable handlebars (106 to 116 cm) and adjustable saddle height (82 to 101 cm), making it suitable for cyclists 155 to 200 cm tall. Its Chaoyang 20 x 3-inch off-road tyres offer good grip and quiet rolling, even on poor roads. The bike also has a Shimano 7-speed derailleur to handle all gradients, and a thumb throttle for intuitive riding.

For added convenience, the Y20L includes free accessories: a front basket, hanging bag, saddle and footrests, making it ideal for deliveries, shopping or family rides. Its easy-to-read LCD display shows all essential information (speed, battery level, assistance level), and its front and rear LED lights ensure optimal visibility, day and night.

Who is this bike for?

This model is particularly suited for:

• Urban and suburban commuting
• Daily journeys (shopping, deliveries, rides)
• Cyclists looking for a practical, easy-to-store folding bike
• Older people and those with reduced mobility, thanks to its torque sensor and smooth assistance
• Users needing to carry loads (up to 150 kg)
• Lovers of elegant bikes with modern design and careful finishes

Performance and range

The COSWHEEL Y20L is compliant with EU regulations: it is limited to 25 km/h and requires no licence. Its 250W motor and torque sensor provide assistance proportional to effort, making pedalling more natural and less tiring, even uphill (up to 30°).

Manufacturer-stated range:

• Up to 150 km per charge (in pedal assist + throttle mode)

In real-world conditions, range depends on many factors:

• Rider weight and load carried
• Assistance mode used (3 levels available)
• Terrain type (flat, uphill, urban)
• Frequency of accelerations

The 48V 15Ah battery (18650 lithium cells) recharges in 7.5 hours with the included 54.6V 2A charger. It is removable and lockable for optimal security.

Comparison and positioning

The COSWHEEL Y20L positions itself as a premium folding electric bike, ideal for urban cyclists seeking comfort, versatility and range. It rivals models like the TENWAYS CGO600 or ENGWE EP-2 Pro, but stands out with its torque sensor, folding frame and exceptional range (150 km).

Unlike many folding bikes on the market, the Y20L is 100% EU compliant (25 km/h, 250W), making it a safe choice for city use without compliance risk. Its open-frame design and included accessories make it particularly practical for daily commuting.

It's an excellent compromise between a traditional city bike and a folding bike, with the added benefit of ultra-smooth pedal assistance thanks to the torque sensor.
