This is a Tuking electric bike for adults that is available in white or black. There are two riding modes where you can choose electric power mode or pedal mode. This means that even if the battery has run out you can still ride it. The battery can last for 35-45km though so you get a decent ride and the 250w brushless motor is powerful but not too noisy. It is also comfortable to ride as the pneumatic tyres are shock proof and are non-slip so the front and rear disc brakes are efficient and safe. It can easily be adapted to different road conditions.
