Simple 50 Cent Cruise Control For Bikes With a Twist Throttle

[6zfshdb]

Do you get wrist cramps from holding your half grip twist throttle? Thumb adapters help but eventually transfer the cramp from your wrist to your thumb.
Instead, get one of these 50 cent plastic clamps at your local hardware store.



Place it over the joint between the twist throttle and half grip. Twist the throttle to the speed you want and the clamp will hold that position.



When not in use, move the clamp to your handlebar.



Obviously, this isn't a true cruise control since it won't automatically compensate for speed gain or loss due to grade changes. It is also not recommended for ebikes without brake lever motor cutout switches.

Looks like there might be room between the right end of the twist throttle and the grip. Folks from the motorcycle world have also used appropriately sized o-rings which create enough friction between the 2 parts to hold the throttle open where desired. O-ring can be rolled out of the groove when 'throttle lock' is not wanted.

Thanks for the suggestion.

I used to use the O ring trick on my old BSA Firebird. The problem with using it on the ebike is the tube on the twist throttle is so thin that the O ring can't generate enough friction to overcome the force of the spring. It's also a bit difficult to roll it out of the way.

I also used Ranger bands (thick butyl rubber bands) on the BSA.

Placing the band over the joint provides plenty of holding force and just folds over on itself to release. The available sizes are limited though and I can't find one that fits the ebike without being too tight or too loose.

An ordinary rubber band doubled up works to some degree but is difficult to get out of the groove when not needed.

I don't use the throttle that much on the bike so it isn't as high a priority as it would be on a motorcycle. The spring clamp idea works in a pinch but is far from perfect.

Thanks again for your reply.

A friend used to stick a tooth pick between the grip and control switch on his motorcycle for cruise control.

I just purchased a thumb throttle from 1859 Northwest. It works perfectly, making it easy to use the throttle on my Rad Rover Step Thru with or without gloves. It attaches securely to the throttle - doesn't slip or fall off - and allows precise movement. Exceptional service from the company! Great product and service to Canada.

I also use the 1859 Northwest thumb throttle and it's definitely a useful product. It doesn't provide cruise control though. For that, I now use this gadget:

The two products work well with each other. The cruise control clamp fits nicely between the thumb throttle and the throttle body with no loss of function on either. At $16, it's a bit more expensive than the 50 cent clamp mentioned in the first post but a lot more convenient.
