BAFANG: World Leader in EBIKE Motors

BAFANG is probably the largest global manufacturer of electric motors at the moment for all types of bikes. Now, the brand offers several motorizations. They are highly appreciated by cyclists seeking a high-performance solution. Over time, BAFANG motors have become even more reliable, torque-rich, and always quiet. Today, the range is very comprehensive. It offers all possible combinations of motorization.

EBIKE BAFANG: Type of Bike

BAFANG eMTB Kit: Electric Motor for EBIKE MTB

BAFANG eROAD Kit: Electric Motor for Road EBIKE

The eRoad motor provides support to road cyclists in all possible situations. The motor significantly reduces the effort of climbing and against strong headwinds or crosswinds. Pedal assistance can be likened to an additional tailwind during training. Of course, the assistance level can always be individually adjusted via the control interface. Starting and accelerating out of curves are also much more powerful on an eRoad bike.

It is always possible to ride without assistance. The eRoad bike then operates like any other racing bike. It is always possible to carry additional batteries to replace those that have been used. In this way, you can significantly increase the autonomy of your eRoad bike for longer routes and other long-distance circuits.

Motors specially developed for road electric bikes are generally lighter than conventional electric bike motors. With the battery, this translates to an additional weight of about 4 kg. Besides weight, you must also pay attention to design. The more compact it is, the lower the aerodynamic effect. The M800 drivetrain system sets excellence benchmarks for these two criteria.

BAFANG eCity Kit: Electric Motor for City EBIKE

For eCity city bikes, there are motors for the front wheel, rear wheel, and mid-drive. Personal preferences are the main factor in the purchasing process. Front-wheel drive has the advantage of offering very low weight. ECity bikes powered by a rear-wheel motor provide a rather sporty riding experience. They often offer the possibility to recover energy during braking (regeneration). The advantage of a mid-drive pedal motor lies in the fact that the center of gravity is low. This perfectly balances the eCity bike. The riding experience is harmonious.

It is preferable to secure the battery with a lock. This feature is particularly useful in the city. It allows you to save time during multiple stops. The lock prevents you from having to remove the battery each time. Some batteries are completely and permanently integrated into the frame. They cannot be easily removed or replaced. This last point plays a key role during electric charging phases. You must choose: move the battery to a power outlet or have a sufficiently long power extension to reach the bike.

BAFANG eTour Kit: Electric Motor for Tourism EBIKE

Thanks to the powerful support of a tourism motor, you can carry much more load and baggage in the panniers. However, be careful not to exceed the total weight of your eTouring bike.

Heavy loads require more motor power. This naturally reduces the battery life. In this case, you can increase autonomy by carrying one or two additional batteries with you. Additional batteries are available from your retailer.

On long routes, we recommend riding with the lowest possible assistance level. Riding economically significantly increases battery autonomy. If you have ambitious daily goals during your journey, it is worthwhile to consider purchasing multiple batteries that you will recharge each evening. You can obtain additional batteries from your authorized retailer.

The Development of BAFANG EBIKES

Over the past fifteen years, sales of electric-assist bicycles (E-bikes) have experienced continuous growth. This has significantly strengthened the ecological role of bicycles as an alternative mode of transport to cars in daily life. This trend is particularly relevant when talking about the electrification of high-quality traditional bikes. These bikes, by nature, are extremely durable and offer the possibility of unlimited repairs. Their components are standardized and independent of the survival of any specific brand or manufacturer.

Constructors’ Planned Obsolescence of EBIKEs

With the rise of electric-assist bicycles, we now observe the emergence of integrated motor systems within the frame. Unfortunately, these motors are often installed with a mounting interface specific to each brand. These systems have a limited lifespan compared to the rest of the bike, including electronic components, belts, and joints. The overall longevity of the bike depends on these elements.

After several years, it is highly likely that the repair shop will offer you a very high maintenance quote to replace the motor and its battery. In many cases, the bike will unfortunately be discarded, even if all other components are still functioning perfectly.

BAFANG EBIKE Motor Independence

By using a motor that can be mounted on a standard bike without any specific adaptation, whether replacing the crankshaft or a wheel hub, the context becomes completely different. Indeed, BAFANG allows the bike as a whole to remain entirely independent of its motorization. Thus, when the motor and its battery reach the end of their life, they can be easily replaced with another equivalent system. This approach offers an ideal solution to combat planned obsolescence.

Autonomy of a BAFANG EBIKE

Battery capacity is expressed in Watt-hours (Wh). The motor consumption is expressed in Watts (W). For example, if an EBIKE motor has a maximum power of 500 Watts and you have a fully charged 500 Wh battery, you could theoretically run your motor at full power for 1 hour. Battery capacity in Wh (500 Wh) / Motor power consumption in W (500W) = 500/500 = 1 hour.

Battery capacity is not always given in Wh. However, voltage and amperage are generally always mentioned. To find the battery capacity in Watt-hours, simply multiply the voltage by the amperage. For example, if your battery is 48 Volts and 10 Ah, its theoretical capacity will be 48 V x 10 Ah = 480 Wh.

In Practice …

In practice, battery autonomy varies greatly depending on a large number of parameters. If stops are frequent, assistance will consume much more with each restart. In the city, it is preferable to consider that the battery is much more strained. The weight of the bike/cyclist combination and the elevation gain are significant factors. Rolling resistance (nature of the ground, tire pressure and width) and weather conditions (temperatures) are also factors that will affect capacity.

Torque and Power of a BAFANG EBIKE

If a constant torque is delivered at startup, it causes the power curve to rise.

The more force I apply to the motor’s rotation axis relative to electrical energy, the faster it will spin and the motor will gain power.

Conversely, when the torque decreases because I reduce the force on the motor’s rotation axis, the power curve drops while the rotational speed continues to increase.

Torque is thus the “acceleration force”.

Power is the resultant that combines this force and the rotational speed of the motor.

Torque

Motor torque is the force of the rotational movement of your motor. It is the torque of a motor that propels the bike forward. It translates the force of the wheels on the ground and, consequently, the acceleration force. Torque is expressed in Newton-meters (N/m). It corresponds to the degree of effort provided to progress. With high torque, your bike will accelerate more smoothly.

Torque mainly depends on the mechanical reduction ratio of the motor gears. The higher the reduction, the greater the motor torque. An EBIKE with high torque will be efficient and will accelerate strongly uphill. At each start, its speed will be lower and limited. The best torque values currently range between 60 and 80 N/m.

Power

EBIKE manufacturers are increasingly announcing a maximum electrical power in Watts (W) and/or a capacity in Watt-hours (Wh). This allows them to characterize and differentiate their products. For EBIKEs approved to circulate on public roads, French regulations limit the maximum speed to 25 km/h. Above 25 km/h, it is no longer an electric-assist bicycle but a moped. The regulations are completely different (Helmet, insurance, license plate are mandatory for circulating on public roads).

Calculating Electric Power

Electric power is expressed in Watts (W). As mentioned earlier, it is obtained by multiplying the nominal battery voltage (24, 36, or sometimes 48 Volts) by the current in Amperes (A) regulated by the controller. For example, a 36V battery coupled with a 20A controller will provide a theoretical maximum electric power of 720W. The instantaneous electric power (W) depends on the effort requested. It is possible that only 250W on flat terrain is sufficient. Zero Watt downhill, if you decide to ride freely.

Temperature of Operation

It should be noted that a 250W motor can easily absorb power up to 3 times its nominal power. This represents about 750W. In practice, it is clear that the motor is never a limiting factor for the electric bike’s power. This regulation role falls to the controller to limit the electric power sent to the motor. In other words, the controller is there to regulate the electric power. It protects the motor from excessive overheating that could lead to its destruction.
