The new Bafang M420 mid-drive drive system with a power of 250W and a maximum torque of 80 Nm, it provides smooth support up to the EU 25 km/h limit. It can be combined with an integrated InTube battery or various down tube and rack type batteries. The M420 is best suited for manufacturers developing hybrid city or touring electric bikes with a mid-drive system, as it can better handle the rigours of urban riding.

Mid-drive motor Bafang M420 (3,6 kg) is equipped with a torque sensor, which allows the control unit to determine how much energy it should feed to the motor based on how hard is the rider pedalling. It differs from its predecessor in the axis of the fixation. The software remains the same. The motor also supports a gear sensor. The redesigned displays come with Bluetooth and USB-out functionality.

Also, Bafang has debuted 450Wh and 600Wh F-Series InTube batteries that can be inserted from the top or underside of the frame downtube. There will be also a semi-integrated battery pack available with a maximum capacity of 1000Wh. The 450Wh battery is the first battery to become available from the new Bafang battery assembly factory in Suzhou. Bafang batteries use Panasonic / Samsung cells 18650.

Bafang has been one of the largest manufacturers of electric bike components in the world for over 10 years. In Europe, its electric motors have become the standard. In the last five years, it has focused heavily on the production of mid-drive motors. In 2014, Bafang introduced an integrated central drive with the codename MAX, which later evolved into the name MaxDrive. MaxDrive has found its use in many types of 250W / 36V e-bikes. Bafang also manufactures the hub (front and rear) motors; this makes it a long-term leader in the world market.
