Re: Hailong 03 down tube battery - how to attach it appropriately?

You could also use these if the tube diameter is max 5cm. But rivnuts might be better option, and cheaper unless you need to pay for the work. In addition, for offroad I recommend using straps, I have these . Even with the base fixed with three bolts on a flat-top down tube, the plastic bends a bit ...

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

SW102 OSF ver 1.1 How do I reset the trip? The readings keep accumulating. They don't reset on system OFF/ON so there must be some button sequence I'm missing. You can do that from the menu, under "Trip memory" if I remember correctly. Press up+down+power at the same time to access the me...

Re: Tongsheng TSDZ2 full thrust in OFF mode

Ah okay, anyway the wiring diagram does not help much here. Apparently speed reading works so connection from controller (inside the motor housing, meaning the electronic system that drive the motor) to display works, but it sounds like the information from display to controller does not work, or wo...

Re: Tongsheng TSDZ2 full thrust in OFF mode

I'm not familiar with this specific problem, but it sounds like the controller goes to sort of "default mode" which can be achieved without a display by connecting two wires (red and blue) in the cable between the display and the motor: https://github.com/OpenSource-EBike-firmware/TSDZ2_wi...

Re: What happens when bike battery cables are wrongly connected? (using TSDZ2)

By the way, have you checked the voltage from the battery leads? If the battery gets short-circuited it might trigger the BMS protection and shut down. Also check the continuity from the battery wires on the controller side. I've fried two TSDZ2 controllers and both didn't show any external damage b...

Hi guys, Everything is going well, but I'm having problems to extract the round module, one of the screws sits very hard and its head is damaged( see picture).

Re: Durable 10 speed cassette and chain?

I've noticed that even with a rather low power (750W) mid-drive the smallest cogs (11t and 13t) wear out really quickly. If you don't need huge range in the cassette, it would be better to stick to bigger cogs. Other option is to buy a bunch of cheap 11t and 13t cogs and replace them as necessary ra...

I have similar problem with my motor, although the power drop happens irregularly and returns to normal after a few seconds. Also the power only goes partially down, current draw being around 0.5 to 1.5 A. Seems to mostly happen when I'm pedaling hard uphill, but sometimes also when driving steadily...

What would you suggest to do in this case? What if I don't mount the wedge at all? If I understand correctly it should prevent the motor from going to the upper left. In my case the motor is already leaning against the frame opening at the bottom. Do you think it would be strong enough to hold the ...

Make sure your battery cutoff voltage is set correctly.

That is a very strange issue. If you already changed the motor controller, I would say the issue is with the hall sensors or motor itself. I don't think the display would be the source of that issue. Also some current goes to the coils as the resistance to turning the motor by hand is increased whe...

I think it depends on what kind of biking you are going to do.

For single track mounta...

It depends on how much current the light draws, TSDZ2 light output can provide only about 500mA and some people have reported the controller failing when using too powerful lamp. Usually rear lights don't use so much power though. With a voltage converter you need to take into account the loss of th...
