This is good. I thought that the magnet needs to touch the sensor, but in this instance my brake levers won't give a lot of a gap when pulled. I've still yet to fit my recently bought kit, but this was concerning me. Now I understand to put the magnet right at the point where *(!)* doesn't show up on the display, which gives plenty of space between magnet and sensor when lever is pulled. Thanks for this. This might be the only video that shows this 👍🏻
I made a mistake thinking the glue would hold.. If the magnet falls off on a remote ride, you are stuck.. I lightly sanded the lever, cleaned it with alcohol, then use hot glue to stick it in place (checked that everything was in the right position) then i took a piece of shrink wrap to go over the lever and magnet. That insures that if the glue fails, i will still have use of the motor.
I never would have thought to look on the display to figure out the best distance for the magnet. I have the default Bafang brake levers with the motor cutoff built-in (on Avid BB7 brakes) and I just hate those levers, so long, so spongy and cheap feeling. I've had a set of Shimano XTR levers (BL-M950) for years and when using those levers in the past on my BB7 it makes a massive difference to the braking power, almost like going from cable to hydraulics. Gluing JB Weld to £100 retro XTR levers... urgh, but it's not like I'd ever sell them.
What if your not using a cycle analyst, can I hook that up straight to my controller? Which wired would I need to connect it to? And hope does it work? How does the absence of the magnetic create the cutout that tells the motor to stop?
Without a cycle analyst it would be difficult to tell when the brake is engaged. the wire to connect it to would be identified in the controller manual. the brake sensor has a copper wire circle that can tell when it is in a magnetic field and it can use this property to act as a switch
I'd prefer to just but these OEM, but none of the best brands make them so I'll stay cable until they do. Jeeze we can put a man on the moon, but 2 years later still can't buy Shimano hydraulic lever with factory sensors.. SMH
Finding dedicated hydraulic e-brakes. Tektro has had them for a while (cheap option, cross compatibility?), maybe others (again cross-compatibility if the calipers and co. don't do it for ya?).
i noticed something totally un-related to the topic. You have your brake levers where you get the most stopping force;...on the top portion of the handlebars. That makes a lot of sense. Your body weight will do more than the pulling strength of your fingers in a situation where there is an accident waiting to happen...you need all the braking force possible.

This made it really simple to wrap my head around how these work, thanks!
This video needs more love, couldn't work out where to put the sensor and magnet until I saw this!
Glad it was helpful!

If you were to disconnect the sensor from the electric system that would allow you to continue using the motor...
i had this issue too during a ride. I disconnected the yellow cable and I fixed the issue. No right brake sensor for the ride, but not a bid deal.

Very useful. Good to know the glues you use too. Thank you.
Glad it was helpful!
what sensor brand do you use?
Is the sensor not confused by all the other metal things nearby?
The sensor detects the magnet, not metal!
Great video! Thank you this worked perfectly
this really helped me, thank you!
Why didn’t you use the same glue for the magnet as you used for the sensor?
what type of sensor is this. where do they sell it and is it a transistor based or mechanical..!! thank you
Could the magnet be glued inside the handle?

in the magnetic field, or its absence, the reed switch is triggered

Would the work on hope technology brakes?
They should!
Can i know what this sensor called ? Where can i purchase it ?
E-brake sensor for ebike
I'd prefer to just but these OEM, but none of the best brands make them so I'll stay cable until they do. Jeeze we can put a man on the moon, but 2 years later still can't buy Shimano hydraulic lever with factory sensors.. SMH
Is there a better way of doing this. instead of bojing it up ?

Link to sensors please
Why not drill an M2/M3 hole and attach that magnet with a screw?
This is NOT a hydraulic brake sensor, this is a magnetic sensor, hydraulic would be inline
Its a makeshift sensor design work without buying inline...
THX !

Smart. It was set that way so it’s easy to install the brake sensors and you’re not trying to fight gravity.
Thanks
My bike thinks its braking and it wont give power
move the magnet closer
