Hello,
Does anyone know where to connect a safety kill switch on Zero bikes ?
-
You don't already have one on your handlebars? Or a key? ???
-
I am talking about the kind of device you attach to yourself with a string to shut down the bike if you are ejected from it. See below :
-
That's to shut off a gas engine so it won't keep running, pumping fuel, heating up, catching fire while your on the ground.
Electrics don't do that.
If your hand is off the throttle the back wheel slows and stops pretty quick. The throttle disable will keep the throttle safe if you need to pick it up, or just key it off.

Bike Jacking.... so i think the request is still valid for electric or gasoline.
After an accident it takes a special passerby to not lift an electric bike by the handlebars and add a twist of throttle - which would be uncomfortable to anyone pinned (unconscious) underneath.
As a point of "special" I thought it was nice in the Gizmag LS-218 video when nearly tipped over - the owner approached, hit the kill switch, then helped tip up the bike. Very few Non-Electric riders would lead with the kill switch like that.
For ease I'd clip into the Kickstand circuit. It is closed when the kickstand is UP, so a kill switch resulting in an open circuit could tie in there quite well.
-
Exactly, the purpose is to avoid a bike jacking.
Thank you for this solution ctrlburn, I did not thought about it.
Most of the device I find on the web are "normally open" circuits.
Do you know if the handlebar kill switch is a normally open circuit as well so it would be possible to connect it in parallel ?
-
The handlebar switch is closed to run so a series connection would be required (I'm pretty sure, it has 5V to switch, not ground). Also the kickstand switch is a three wire hall effect sensor, not so simple to connect another switch there.
The rear wheel will spin for a long time in the air if it was already revved, and the throttle can dig into the ground and stick on, just like a gas bike. But the inability to tell that the the bike is on and ready to run but silent is unique to electric.

I haven't been to a drag strip in years but when I was racing ( Long Long ago in a galaxy far far away ) a "dead man's switch" was necessary to pass tech.
A wire or string was attached to rider's wrist and to an on off switch on the bike. If the bike and rider were separated, power to the engine would be disrupted.
For bikes that were raced often, a permanent connection was made. For a one off or seldom used bike I could sometimes slide a soda can pop top in between
the switch and the housing. A small hole could also be drilled into the switch so that a piece of string or wire could be fed through.
While it is true that the bike will slow naturally once throttle is released, I am sure that everyone has seen videos of a riderless motorcycle continuing on for a while.

First my response was to the OP's word "ejected" even though the title says bike jacked. A Zero that doesn't have the throttle regen down to 0% will stop pretty quick. A throttle disable won't effect that motion one bit. Hitting your throttle kill switch in a safe area will show it won't "stop" the bike.
These switches are good for jet ski's and most any watercraft as you want to be as close to the boat as possible if you hit the water.
As for a bike jacking, well if someone(s) removed you from your bike it's because they want to "make a better life for themselves" and if they can't get away they may feel "disrespected" and share their inner pain with your outer body.
If your not ready to shoot them, best to let them have it and let your insurance buy you a new one.
But make your own call.
-
It is only in USA that people have guns. I would rather fight or run as long as the thief doesn't left with my bike.
You can't just call your insurance and get a refund, you need proofs.
-
I see.
Well I hope it works out for you.
Enjoy your bike.
-
I have bought the switch for my seadoo and it had three poles- common, normally open and normally closed, that was many years ago but you should be able to find one like that, I think that they are called a dead man's switch (not even going to touch the gun debate part of that! I'm Canadian)
-
Thanks Ndm, I need to find one of those
-
I know that they have a big red button on the tail for the Race Zeros so that you just slap it and it stops "running"
I would imagine that a switch could be tied into that circuit.
-
This discussion takes us back to the need to authenticate the rider. Tesla Model 3 car will be using a phone activation and an RFID tag; Would the same process be useful on a motorbike?
-

Actually that sounds like a Single Pole Double Throw (SPDT) switch.
-
Interesting. We can imagine an option in the zero application shutting down the bike if the Bluetooth connection is lost
-
The phone thing is a good Idea as a backup. Maybe a keypad in addition
to the key. I work Valet in Vegas. We had a guest drive his Tesla in having
left the house with only his phone. Once in the parking garage, there was
no signal so car was stuck in the middle of the driveway.
There have been articles in the paper about people using their
phones to start and drive their Tesla and ending up where they have
no cell service. They then have to find a way to get back to where the
key is, or if they have someone with them, to someplace that they
have signal and "start" the car so that the person with it can drive
it to them. The Model 3 ( STILL haven't gotten my configuration page )
comes with a "valet" key.
-
When I lowsided some guy came up and grabbed the throttle to lift it and highsided it onto the other side. Grrr.
-
where they have
no cell service.
OT - I know that a machine shop is working on a satellite antenna that is embedded in the roof of the car for a self driving car from a major manufacturer.
I've been thinking about other things that they could use that for, I bet the car could be a hotspot on whatever networks (Bluetooth, WiFi) they want for passenger verification with a phone even away from cell networks, assuming a smartphone of some sort with a encrypted key that was downloaded when they hired the car.
-
I would be very interested to know what they plan to do in the reported scenario, underground/multilevel parking garages. where there is no possibility of any signal even thru mesh networks of other cars. I would assume some sort of encrypted key would not require any network attachment, as long as the car has the key, which should be no problem for the owner, only renters.
That fact also makes me wonder what tesla is doing if the car could be stranded ... this is the first time I've heard of such a thing...

Hello,
Does anyone know where to connect a safety kill switch on Zero bikes ?
Wouldn't a twist on the keyless ignition concept (twist is that there isn't even a button, just the proximity detection which triggers a relay) in combination with the regular key be the solution for bike jacking?
While this still won't make any difference if you lowside, want to pick up the bike and forgot to hit the kill switch (happened to me) ... but it's perfect for a bike jacking.
The thief is able to take off with the bike but it will stall 20m down the road. You're out of range of most of the aggression of the thief towards you and when he finally tucked tail you can pick up the bike where he left it for dead.
some other posts from this forum containing the same concept:
