More info


World No. 1 in the manufacture of bicycle motors since 2006, the reputation of the Bafang brand is well established. Reliable, silent and terribly efficient products. OZO has been an official Bafang distributor since 2010.

The engineers at Bafang designed this engine to make it as reliable as possible, but also easy to install and maintain.

To get your idea of ​​the installation, we invite you to watch the assembly tutorial. 

Some of our customers have traveled more than 100,000Km with this engine.

We recommend this kit mainly to women for its flexibility of use but also to all cyclists under 80Kg who wish to have the widest possible range of use.

The BBS02 750W 48V crankset motor offers a torque of 160N.m which places it ahead of all other 750W crankset motors on the market.

This torque will be able to climb up to 110N.m with the "short transmission" option that we offer in the MTB / Cargo version of this kit and the optimized mapping.

In addition to being more efficient than its competitors, it is also quieter thanks to its integrated vector-controlled controller.

The Bafang 750W middle motor kit can be installed on 90% of traditional bikes without modification to the existing frame.

Another advantage and not the least, this engine has been developed in order to keep a traditional bicycle transmission, you can ride as on a standard bike with a 44 teeth or 46 teeth chainring and not a small 22 teeth as on some brands.

For mountain bikers or pilots over 80Kg note that we offer an optimized MTB version of this engine in which the maximum torque rises to 160N.m.



The Bafang BBS02 middle motor is installed in place of the original crankset.

Designed as a single unit, it integrates the motor, the controller and the pedal sensor.

Installation is easy and does not require any modification to the frame.

All the screws required for installation are supplied as standard.


All connectors are waterproof and have visual keying. You can't go wrong when plugging in.

A single cable goes up from the engine to the handlebars to connect the various accessories:

2 Red connectors for brake cuts

1 Green connector for the control screen on the handlebars (display)

1 yellow connector for the accelerator (optional)


Il faudra alimenter votre Kit moteur pédalier BBS02 avec une batterie 48V. Toutes les batteries 48V de notre catalogue sont compatibles avec ce moteur.

Le choix de la capacité de la batterie devra se faire en fonction de l'autonomie que vous souhaitez. Par exemple, une batterie 500Wh, vous offrira environ 50Km d'autonomie sans forcer sur le vélo et jusqu'à 100Km en fonction de votre effort. Une batterie de 1000Wh, vous donnera le double d'autonomie.

Le deuxième critère à prendre en compte pour le choix de la batterie sera de savoir où vous voulez installer la batterie sur votre vélo.

Check the dimensions of the battery by going directly to the article sheet of the battery concerned in order to confirm that it can be installed on your frame.

We offer these batteries in 4 versions:


- 840Wh




The above autonomies are mentioned for information only. This is an average distance that a cyclist of 75Kg can cover with a city bike or VTC or Road on a hilly course. For the above range calculation, we take a consumption base of 7Wh / km. The actual range that you will get will depend on various factors such as your weight, tire pressure, the difference in level of the course ... If you want to know more about the estimation of the range on an electric bike, OZO put to a complete article entitled "How to estimate the autonomy of your electric bike".


Black and white vertical display, entry level: Black and white display, it combines all the main functions. The original mount is intended for installation on the handlebars, but we offer an optional stem mount for the MTB. 9 assistance modes. 

Compact color display: Its compact format makes it perfect for committed mountain biking. It sits on the left of the handlebars so you cannot use it if you have the derailleur lever on the left of the handlebars. 9 assistance modes.

Vertical color display: With this display, you access what is best on the eBike market. This model displays more parameters and it has an auto-adaptive backlight and a USB port for charging a smartphone or GPS while riding. 9 assistance modes fully configurable by the user: You are free to configure the 9 modes so that your assistance best adapts to your needs.


The accelerator offers the possibility of controlling the engine without pedaling.

In the form of a thumb trigger, the throttle can be installed on the right or left of the handlebars.

Note, however, that the accelerator is not approved for driving on a road open to traffic.

He finds his interest on a mountain bike to help with hill starts and obstacle passages.

The brake cut-off is an additional safety device which cuts off the power supply to the motor during braking. This is particularly very practical during delicate maneuvers in town in particular.

The brake cut-off comes in different forms:

The brake handles that replace your original handles.

The cable sensor which is installed on the brake cable and which keeps the original handles (ideal for road bikes with pressure cookers).

The magnetic sensor to be reserved for bicycles equipped with hydraulic brakes.

The derailleur sensor cuts off power to the crank motor during gear change, thus preventing premature deterioration of your transmission.

We strongly recommend it for mountain biking in which the speeds are often changed "on the fly" by two or three.

OZO has selected the best electric bicycle tires on the market for you. German manufacture Schwalbe tires have a thick anti-puncture protection and a very resistant rubber.

Their lifespan is of the order of 10,000 km.

You will find all the tires in the tires section

The battery is delivered with a 2A charger as standard.

If you want to halve the charging time, you can opt for the 36V 4A charger.

Adapter for 4-hole or 5-hole table top.

Allows the mounting of conventional transmission chainrings to the MTB standard 4 holes (4x104 BCD) or 5 holes Campagnolo (5x135) or Shimano (5x130 or 5x110).

Also offers the possibility of making a double plate assembly.

The Bafang motor is assisted by the pedal. It is the chain of your bike that will transmit all the power of the engine. It is advisable to install a reinforced chain in order to prevent the chain from breaking.

You will find reinforced chains for crank motors in the reinforced chains section.

The only specific tool you will need for installing the Bafang crank motor is the torque wrench.

Note that this tightening wrench is also used to unscrew the outer bearings of the Shimano Hollowtech bottom brackets.

Disassembling the original crankset from your bike may also require more standard tools such as a crank remover or a square axle bottom bracket remover.

You can buy all the item here HERE.

Factory mapping will be fine for urban use, but some will find it lacking in dynamism.

At OZO, we have developed an optimized mapping allowing to reduce the response times to the activation and to the stop of pedaling and to draw the full potential of the pedal motor to such an extent that the customers having compared the two mappings ask us why we do not only offer ours because the difference in performance is so obvious.

For specific projects, we can optionally create custom maps in order to configure the response times, the acceleration curve, the torque and the speed on the various assistance modes, the operation of the accelerator, etc.


The BBS02 crankset motor is designed to be installed on BSA standard frames, i.e. with an internal case diameter of 33.5mm (Measure A) and a length of 68mm to 73mm (Measure B)

There are two types of mounting for bottom bracket bearings, those with internal bearings and those with external bearings. In both cases, measurements are always taken at the frame level as illustrated opposite.

The measurement A corresponds to the internal diameter of the case, it is taken inside the tube edge to edge. The standard is 33.5mm. If you have more, you will need to take the appropriate adapter.

Measurement B corresponds to the length of the frame box, this is done between the two ends of the frame tube. You must have between 68mm and 73mm. If you have more (83mm, 92mm, 100mm ...) you will have to choose the BBSHD crankset motor.

To be sure that your measurement is correct, we invite you to watch the video "How to measure the bottom bracket of your bike?"
