Yeah, I think I'll change it back.
I'd still have 9 PAS modes.
And I think that it starts up in PAS 1 anyway?

The same sort of thing was happening back in the 70's with gas powered Mopeds.
They too were "just bicycles" but people were getting hurt.
IIRC in Canada, you just needed to be 16 and wear a helmet?
Same as ebikes now.
(I'm not sure about a speed limit?)

I've had the bike take off on it's own twice so far. Both times it was because of an open in the throttle ground circuit. Luckily, I was able to grab the brake before it got loose. I now keep my hand on the brake until I turn off the power button as a precaution. I'm trying to think of a "dead man" control of some sort.

The bike I was referring to went to a 70 y.o. non-rider, unfamiliar with throttles. It raised its front hooves and bucked up as he was walking it, hence the thumb push in not down throttle. He can ghost pedal it for a few days until the PickUp tires arrive with the new throttle. The half-twist was too scary for him. It is temporarily disconnected.

How about saddle down pressure? No one on the bike, it doesn't have power.

That would help, but it wouldn't prevent the bike from taking off unexpectedly at a stop while I'm still seated. Such a switch would also be difficult to rig on my saddles, which I change frequently.
I'm thinking of something more sophisticated, like a proximity switch.

Probably wouldn't be that hard to implement with a micro switch on a suspension seat post.

It's that damn Hal sensor circuitry !!
I built a "proper" throttle using a potentiometer with a resistor before and after the potentiometer.
When I disconnected the ground from the circuit, I registered a throttle fault because +5 V was sent down the signal wire.
With a Hal sensor throttle +4.1 V is sent down the signal wire with the ground disconnected.
I don't know how to build it, but I Know it's possible to redesign the Hal sensor circuit to go to +5 V when ground is lost.
A mid-drive throttle (with the connector plugs reversed) puts out +4.1 V at zero throttle, and +1.2 V at full throttle, so when it loses ground, the throttle goes to zero, or registers a fault and shuts down.
Being as the resistors before and after the potentiometer are roughly the same, simply swapping the positive and negative going to the throttle, switches the throttle from mid-drive to hub-drive, or vice versa.

Or add a second momentary contact push button on the opposite grip that needs to be held to operate the throttle.
Seems like overkill to me since I've not had any issues.

They're starting to use something similar on jet skis now to replace the old wrist strap & lanyard. Too many runaways from operators not using them.I think that this proximity switch has a two foot proximity, approximately.

I don't know what you're talking about ???
Does he have one of these throttles,..
Or a throttle like my half-twist throttle with an on/off switch?
Or does he have something else??

It is like this. It feels much more natural to sustain
It is easier than pushing and holding the thumb down.

So the lever hangs down underneath the handlebar grip ??
Can you post a picture of it installed?
I'm having a hard time picturing it in operation.

EDIT:
I think I found it,..
It says 65° rotation angle.
Does it actually have a 65° active "sweep angle" from the start of power to maximum power?
My throttle is only has an active "sweep angle" between the two lines with huge "dead spots" before and after the active area of the sweep.
Almost half the sweep angle is dead leaving me with a pretty twitchy throttle response.
2mm of "pointer" movement has about a 5 kph speed difference.
The throttle doesn't end up being very granular at all.
(I am used to it though.)
