SAMEBIKE CY20 Folding Electric Bike

The SAMEBIKE CY20 is a folding electric bike designed around a compact commuter-friendly format. Its foldable high-carbon-steel frame, adjustable handlebar and 20 × 2.35-inch tyres make it suitable for riders looking for easier storage and a practical setup for regular journeys.

Power comes from a 250W rated motor, paired with five pedal-assistance levels. The manufacturer specifies a top assisted speed of 15.5 mph, giving the CY20 a straightforward electric-assistance setup for commuting and general everyday riding.

A 36V 13Ah battery supplies the electrical system. The manufacturer states a maximum range of 56 miles, converted from the published 90 km specification, providing a useful headline figure for comparing the CY20 with other electric bikes.

Real-world range will vary according to rider weight, assistance level, gradients, road surface, tyre pressure, temperature, stopping frequency and riding style. Higher assistance levels, frequent starts and hills can reduce the distance achieved from a single charge.

The CY20 uses 20 × 2.35-inch tyres together with front-fork suspension. A Shimano 7-speed drivetrain gives the rider additional gearing options, while the folding frame helps reduce the space required when storing or transporting the bicycle.

Mechanical disc brakes provide braking at the front and rear, while the bike also includes an LCD display, USB charging port and detachable throttle according to the supplier specification. Charging time is listed as 4–6 hours, with a bike weight of 28 kg and a maximum payload of 150 kg. Folded dimensions are approximately 84.5 × 53 × 69 cm.

Overall, the SAMEBIKE CY20 combines a 250W rated motor, 36V 13Ah battery, 15.5 mph top assisted speed and 56-mile manufacturer range with folding capability, front suspension and Shimano 7-speed gearing. Its compact wheel format and adjustable setup make it a practical option for everyday electric-bike use.
