xtrajack,

I was unable to use a modification for the thumb throttle developed by a member on the ebikeforum.com site. http://www.ebikeforum.com/electric-b...throttles.html I have the Currie conversion kit installed on my 21-speed mountain bike and my thumb throttle is different from the ones used on the Izip and Ezip bikes, plus I have grip shifters on both sides of my handlebars since I have a 21-speed bike. My solution since I couldn't use the ebikeforum.com mod was to use a large O-ring that's zip-tied, not an elegant mod but it works. The O-ring is placed behind the thumb throttle and large enough that I can pull it over the thumb throttle and keep it in place. I only use it when going on long distances on roads that have shoulders and minimal stop signs or lights, like my 9-mile trip to the closest town--I ride in a wide shoulder and have no stop signs or lights until I get into town. This isn't an elegant solution and I wouldn't recommend that someone use a cruise control if they ride their bike in a congested area or an area where they're on the road rather than a shoulder. I've attached two photos, one blurry that shows the O-ring on the throttle and one that shows it when not in use (you see it behind the throttle). I'll see if I can come with a better solution at some point. You may not have any problems using the modification described on ebikeforum.com. Good luck.
