LCE930 in testing https://www.instagram.com/reel/CpPJzuTsJQx/?utm_source=ig_web_copy_link

There are two versions of M820, one is 36V, the other is 43V, the same motor, but the voltage is different.

Bafang said BESST can be use for all bafang's motor

I consulted Bafang Company, whether it is possible to use a 36V M820 motor with a 43V BT F014 battery, but they did not answer me positively.

yes, M820 have 36V, but the main battery is BT F014 410wh, it's 43V, that's the problem, To keep the main battery and the motor consistent, it is best to use 43V,

size L can not be loading in mid-March , the early time is mid-April, confirm with carol please,

Not sure yet, our biggest difficulty is that the Bafang battery is 43V, so the motor is also 43V, which requires the backup battery to be 43V, but, the battery manufacturer said they only supply battery 36V. the battery box only can put 10*2 cell, 36V*10AH， not 12*2 cells, 43*10ah,

The auxiliary battery is not connected to the main battery, but used separately, and the auxiliary battery is directly connected to the motor, and only one of the two batteries can be used at a time.

The tube wall without openings has a better structure, In terms of the overall rigidity of the frame, the dispersion and absorption of vibration, and the support of weight, etc.

1. Because the motor and battery are relatively light, so need keep the center of gravity at a reasonable position. 2. Ensure the pedaling frequency of the motor in assist mode. 3. In the case of no electricity, it can be used as an ordinary MTB bicycle for uphill traffic. 4.The BB height of...

This is the size of the box of range-extending battery, the battery manufacturer give me that. It can only be installed with a 10*2 cell arrangement, 36V*10AH. What we want to try is a 12*2 arrangement, that is, 43V*10AH. and some problem is till no solved

you are right, The biggest problem now is that the main battery is Bafang BT F014, 43V, so the motor also uses M820 43v, and the range-extending battery is 36V, the battery manufacturer is still thinking about it,

The box for range extension batteries, 36V* 10ah， the supplier of te box only supply box, no cells and battery protection board, wire connector, etc.

it's all-mountain, The main feature of the ultra-light EMTB is its all-terrain ability and multi-style play. It is not a dedicated enduo bike. Therefore, although it can jump, it is not recommended to be used exclusively for downhill and jumping.

yes, we have size S/ M/ L,

No, Bafang have no supply the battery on bottle cage, we discuss it with a company who can supply 360wh battery, with 20 pcs Samsung or LG 21700cell, about USD$200/set

Now we are still communicating with Bafang Company, we want to get an ideal price, and Bafang Company also wants to get our frame, so we need to wait for the completed test of Bafang Company in March.

A rough calculation of the weight after spraying the transparent paint is 2950±45g/Medium，In fact, the weight of the frame could be reduced by 500g if more control was used in the weight control, but doing so would cause some parts of the frame to be weak, so we strengthened these weak points...

front travel 150-160mm, rear thravel 150mm, the leverage curves need later, We need to wait for the complete vehicle test of Bafang Company. They chose our frame and used it to assemble their products as exhibits in March. Their engineers made some small suggestions for our frame.

Size L can only be placed in the third batch of orders now. Around the end of April, the first two batches (early April) are full.
