Why are you writing all this in this thread? Don't you like golden bicycles?

My first version of the M510 motor is still running today. A friend bought it from me and he is very pleased with it. There were no problems with the M510 engine. It works very quietly and smoothly. How many engines do you know of the first version with big problems?

You're talking about the power reserve. What kind of bafang engine do you compare with bosch?

Maybe the first version of the M560 motor has increased consumption.

This is a subjective test for the same power and acceleration.

The test was carried out on a 5A 48V battery. The average speed in the ascents was 8km h. If I could discharge the battery on the M560 to 39V. I think I would have driven 20km. But it's still a big difference.

Cef49 (M560) - 22kg, Cef50 (M820) - 18,5kg, e10, M600 - 25kg. I'm tired of the noise of the M820 and M560 engines. Therefore, I decided to assemble the E82 with the M510 engine. I used to have an M510 v1.0 engine and it was very quiet. Do you think the CEF50 frame weighing 2.7 kg is a good...

All companies started with heavy bikes. I hope that soon we will see a bike with an M560 motor weighing 20kg :-) And it will be very quiet, like the M510 motor

Perhaps it is very heavy for the m510. 25 kg is a lot

The frame is designed for a 170mm fork. When installing 190mm, the geometry of the frame will change. Ask the seller if they can provide an adjustable cane creek steering column.

Ride on the M820 43V and M560 (500W) 48V motor. The battery is 48V 5A. Both motors are set to 5 acceleration. M820 40% - 250W. M560 - 25% - 250W. The route is the same. The speed is about the same too. The battery on the M820 is discharged to 39V, the firmware is 43V. The battery on the M560...

Can you weigh the battery cover and mount? I was sent photos, I think that the frame without fastening and this heavy lid will weigh 3.3 kg. I have a light battery in a carbon case. I'd rather make a new lightweight battery cover. I also want to buy this frame for the m510, but if it weighs no...

I do not know who sells this part. This detail is easy to make yourself.

This is not the best version of the display. It does not connect to bafang go+. There is a newer version of the C030 with bluetooth and a larger screen. But it is necessary to make a large hole for it. Or you can print such a detail on a 3d printer and make small holes in the frame for the wires

Beautiful stickers. Where did you buy them? What is the name of this gray color? To make dengfu understand me

I've been angry at Dengfu many times. But they have a good frame for the M510, M560. And I continue to communicate with them. I hope that someday they will learn how to make light frames. Although if you throw all the extra parts out of the frame and even replace the heavy battery cover with...

My m820 motor produces 650W of power on a 43V firmware and a 48V battery

Of course you're right, this is physics. But if you throw away all these metal fasteners, then the frame should weigh 3100-3200g. Why do we need them if we can make a carbon battery lighter than the factory 700g. When I was making a cutout in the CEF50 frame weighing 2650, I was advised by an...

How many years must it take for these frames to start being made without mistakes. After reading the forum, we understand that any Chinese brand makes mistakes and we fix them. Why can't you make a 3kg frame with a removable battery for the M510, M560 motor. As we can see, the CEF50 frame has a...
