How can I install brake inhibitors?

[ClintBX]

Hi ESFMs,

For a long time I haven't bothered with having brake inhibitors set up within my levers. I used to have them in a previous ebike as it came stock with the conversion kit but since setting up my current ebike, I couldn't use that kind of brake lever because my gear lever is integrated with the brake levers and they just fit the bike really well.

Buuut.... After experiencing some phantom throttles at inappropriate moments the other day, I realized how important it is to have that cut off.

I've been looking for tutorials on how to set one up on my current lever but all it shows are how and where to attach magnets and nothing about where on the controller to connect it.

How do I go about setting this up? What do I need?

Also, I want to add that I'm not using a cycle analyst or any kind of display setup.

The switches within the brake lever are a simple on-off switch that are normally off, also known as normally open (NO). When the switch closes, the motor will turn off immediately, and regen, if the controller is equipped for it and enabled, is engaged.

Many thumb and twist throttles have a switch housing built into them. Some have a switch located in a spot pretty easily reached with your thumb (without letting go of the handlebar). That switch can be "repurposed" as a kill switch by installing a momentary, normally open push switch (like a door bell button). All you would need to do then is take the same 2 wires that would normally lead to your brake handle, and install them on your new switch. Makes no difference which wire goes where.

Here's the switch I used on the last bike I did - where I couldn't swap the brake levers.

Depending on your controller and how you desire wire it, your brake or motor kill safety can be actuated by...

1) Brake sensor wire being shorted to ground. (Low state). 5 or 3 vdc supply.
2) 12 vdc power conducted to the 12vdc Brake input (High state).
3) Or even a 5 vdc variable output to an analog input.(analog)

If you supply some controller specifics, we could be more accurate.

As most people IMO tend to hit the breaks under panic situations , I would highly recommend brake switches on both brakes as the primary motor cutout. Especially important if you allow other riders on your bike... just sayin. With the added kill switch mentioned above as a secondary feature, say if you want to regen without touching the brakes.

So - it sounds like you got another conversion kit but didn't use the ebrakes that came with it. Or you bought a kit without ebrakes.

Your new ebrake conversion will hook up to the original two wires if you left the ebrakes off, otherwise you need to post a link to the kit or a picture of your controller wiring to be able to figure out where to connect the ebrakes.

Another option is to use TripWire switches which are a bit pricey but do not require any fabrication skills. See: http://www.ebikes.ca/catalogsearch/result/?q=tripwire and video here: http://www.ebikes.ca/learn/videos.html
