Thumb throttle CRUISE CONTROL no cost in 2 seconds

Bike me · Mar 5, 2021

1. Turn bike on
2. Hold brake lever to engage motor cutoff switch in order to prevent bike jumping forward
3. Push thumb throttle to position wanted
4. Insert cable tie at extreme angle to find the channel, insert all the way till it stops
5. Let go of brake and you're off! ZOOM!!!
6. Use brake to reduce speed or to stop
7. DO NOT FORGET THAT YOU HAVE THE THROTTLE ON when you finish your ride or whenever you let your hand off the brake
8. Remove cable tie until next time you need cruise control
9. If you forget to remove the cable tie when you get home, don't worry - the cruise control rig will not operate until you do the procedure again with bike turned on

There's no "Hi Ho Silver, Away!" early morning accident. That's nice. Be aware, though, that when you're out riding, any time you let off the brake...zoom!

I used a cable tie 5mm wide to fit the channel.

Be hard to do while riding the bicycle at the speed that you want.

Why not just buy a cheap controller or kit that already has cruise control.
Operation is that you just dont move the throttle (for a set amount of time) while your riding and it sets itself until you hit the throttle or press the brakes.
That method is much more safe.

I have an easier one;
I took the inner plastic sleeve out of my left-hand, half-twist throttle and while it still "snaps" back, it doesn't do it quite as fast and freely. My grip is a Richie foam (nice!) that fits snug, but can be rotated if I twist it. If I rotate and apply a little inward pressure it will move up against the end of the throttle and hold it in place. To release, all I have to do is touch the throttle and it snaps closed.
It's actually easier than taking my hand off the grip to switch the cruise on.

markz, thank you for your interest and input.

Indeed. So you don't do that.

You might kill yourself trying.You set the throttle for what you estimate it needs to be for a certain top speed on flat road, before you take off.

That's more sophisticated and safer, but not worth expense and especially not worth any trouble to install because the mod works perfectly on my basic bike. Of course, in city it's only for emergency like injury and with frozen hands, in order to get home. On highway or country road, it would be great to use if you're tired of pedaling and just need to get where you're going.
Since my bike only goes up to 32 km/hr, full throttle is fine, and braking cuts off the motor.
It wouldn't be ideal for all bikes but for a basic and heavy bike like mine, it's fine.
One cable tie onboard and you're set for getting home in emergency.

Nice.

I forgot to add that you'd need to hook up the cruise wires on the controller if it has cruise. I find I didnt like it, because it would go on cruise when I didnt want it to.

You could find a way to hook up a silder switch - like those you find for the dining room table that dims the light.

Hey, thank you! Clever ways to do it.

I hooked it to an unused switch on some handlebar control I had - honestly, I forget, which is easy because I never for a moment had any desire to turn the cruise control off. I don't think it was the horn button, because that would be momentary ... hm.

Tape works well to for cruise control.

I just jam the grip tight up against the throttle on half twist throttles, creates enough friction to hold it there. No pas on my bikes, so none of those issues.

Many large motorcycles have a similar feature on the throttle, You twist the cap on the handlebar end, and it puts the pressure on the throttle, holding it there for highway cruise.

Yeah, A popular MC throttle locking device back in the '70's/80's was called the Twist Assist. I think it was the first.
Before that, I used get a really thick O-ring from the hydraulic parts store and roll it w/my palm into the crack between the grip and the throttle/handle bar switch housing.

Elastic band, freebie if you hit up your local office supply store (Staples) photo copy area. Probably take you 1 second to install.

Drop bars and throttles don't work well together. So it is always a cruise throttle. Throttle is the CA aux pot with a 1K resistor.

It'd be easy to use the same as a thumb throttle on a flat bar bike if the rider always uses a cruise throttle. It'd take some getting used to.

For safety mine has front and rear inline brake switches and PAS ring. No PAS, just pedal first. With a 12 pole ring and higher cadence settings the cut-off is very snappy. On startup the throttle has to be zeroed before it will do anything.

On my motorcycles I use a heavy duty O-ring. I'd do something similar with a thumb throttle.
