Ebrake compatibility? (Bafang/Tongsheng/Other brand)

[mittkonto]

Hi there!

Lurker for awhile and soon to order part for my first build!

Simple(?) question; Are ebrakes interchangeable between Bafang/Tongsheng/Other-brands?

(About to click "order" on a Tektro Auriga E-comp E-bike Hydraulic Disc Brake Set, for my TSDZ2.)

Depends.

Some brake levers use a switch, and have two wires.

Some use a hall sensor, and have three wires.

If the controller needs a two wire connection, use the first one.

If the controller needs a three wire connection, use the second.

Note there are two types of the first one. One of them is NO, Normally Open, and it closes th switch wen youpull the lever. The other s NC, NORmally Closed, and it opens the swithc when yopull the lever. Most controllers use the first version.


Some controllers also have the ability to read an analog signal (like a throttle, potentiometer, etc) to provide braking that is not just on/off, but is proportional, and use a second connector for that that has three wires, but use a two wire connection for the switch that engages the mode first. The second connector isn't usually rquired, and when not attached defaults to on/off braking mode.

It seems, according to a googletranslated amazon.de review:

Unfortunately, the brake did not help me because I was looking for something that outputs a brake lever proportional signal. That does not make it, there is only an "on", or "off". Exactly two contacts.
Since the description says otherwise and the brake is otherwise processed super and brakes well, yet all 5 stars.
If you are looking for a "brake light switch", or just want to switch off the engine support when braking, you will find exactly what you are looking for.

Thank the gods for good ol' German precision reviews.

I suppose, it's not a hallsensor and aught be a magnetic switch, which should be no problem according to the tsdz2 wiki.

Worst case scenario, "some assembly required".

Sounds, about right?
