SAMEBIKE M20 Retro Fat Tyre Electric Bike

The SAMEBIKE M20 is a retro-style electric bike built around a 20-inch wheel format and high-carbon-steel frame. Its 20 × 4.0-inch tyres, long saddle profile and non-folding design give it a distinctive layout suited to commuting, everyday journeys and mixed-surface riding.

A 250W rated motor provides electric assistance through five pedal-assistance levels. The bike has a top assisted speed of 15.5 mph, while Shimano 7-speed gearing allows riders to adjust mechanical gearing to suit different gradients and riding conditions.

The removable 48V 18Ah battery provides a maximum range of 87 miles, with approximately 43 miles available in pure electric mode depending on riding conditions and assistance level.

Actual riding range can vary depending on rider weight, assistance level, gradients, road surface, tyre pressure, temperature, stopping frequency and riding style. Higher assistance settings, frequent acceleration and more demanding routes can reduce the distance achieved from a single charge.

The M20 uses 20 × 4.0-inch tyres together with front-fork and rear suspension. This dual-suspension configuration helps manage surface irregularities while the wider tyre profile provides a larger contact area for everyday and mixed-surface riding.

Hydraulic disc brakes are fitted alongside a colour LCD display, Shimano 7-speed drivetrain, USB charging port and thumb throttle. Charging time is 4–6 hours, the bike weighs approximately 40.5 kg and supports a maximum payload of 150 kg. Overall dimensions are approximately 170 × 67 × 112 cm.

With its 250W rated motor, 48V 18Ah removable battery, 15.5 mph top assisted speed and 87-mile range, the SAMEBIKE M20 combines a retro 20-inch format with wide tyres, dual suspension, hydraulic disc brakes and Shimano 7-speed gearing for regular everyday riding.
