Although the entire group weighs only 4.4kg a few years ago, the idea that the electric assisted road bike was almost out of reach has shocked many cyclists by this idea! But now, Bafang, a well-known manufacturer of electric vehicle components and complete electric drive systems in China, announced the launch of the mini mid-drive motor, which is specially used for road vehicles, Gravels and mountain bikes. This is precisely due to the new car type "Gravel bike" on the market and the age of the road vehicle group, which prompted Bafang to develop this new driving system - M800 mini mid-motor drive system.
The entire group weighs only 4.4kg
Bafang believes that the appearance design of this new mini motor has created novel and iconic design opportunities for brands around the world that are developing "Electric Road Race" bicycles, including bicycles with gravel road and off-road concepts. One of the main advantages of the new drive is its light weight, with a total weight of less than 2.3 kg, but its output power can reach 200W and its maximum torque is 55Nm. The electronic components and the 200Wh down-tube battery add only 2 kg, and the entire system weighs less than 4.4 kg, including the monitor and speed handle.
is equipped with a dual torque speed sensor
functionality is the key. The system is equipped with a dual torque and speed sensing device, which is quieter and more stable in use. The motor has compatibility with single and double gear discs (drum sizes 44T or 34/50T), which can easily set the speed limit to the EU-specified speed of 25km and its maximum speed is 45km, so the system can also be used for high-speed electric assist bicycles. The pedaling assistance degree is controlled using 1 or 2 Satellite shifter pods, divided into 5 steps, and can be placed separately on the downward handle. The 2.2-inch TFT color display offers up to 10 sets of settings.
electric road vehicle will quickly exceed the legal motor-assisted speed threshold specified by the EU by 25km, and the drive system will be adjusted to its optimal state when the user starts and accelerates as well as short sprints and steep climbs. For the United States and elsewhere, the speed limit sets
to speeds of 32km or 45km per hour. But regardless of the actual speed limit, the most important thing is that when the speed limit is reached, the drive unit runs almost without resistance. Therefore, when the cyclist exceeds the speed limit, the pedaling force will not be affected. This is usually when the rider pedals at a speed of 20km to 30km.
M800 The battery pack has a capacity of 200Wh, and it may make a little sound on the side at the beginning. However, since power is consumed only when climbing hills and starting or accelerating within the speed limit range, the battery capacity is enough to ride long distances, and the range can reach 50 to 90km, or even longer.
This development also clearly shows the design method used by Bafang and electric road vehicle industry for electric road vehicles: motor assistance is only suitable for long-distance or steep climbs, and there is less continuous assistance for "general" riding situations. Bafang believes that the performance-oriented electric bicycle consumer group has gradually increased, which has led many brands to actively launch corresponding models, especially for the rapidly growing E-Gravel and E-MTB types.
