Well the ones I saw, the throttle worked as normal...unless you rolled back on the throttle and the end at the same time, then it locked. He disengaged it by just rolling the end foward or the throttle and the end at the same time. I know they're pricey, but doesn't look bad at all and when I take it to work, its 32 miles one way and about 27 miles of it is open highway. Living in PA, there is a lot of wide open straight roads without a red light in sight, so I would get my use out of it! Maybe if there are enough people that want to get these, maybe we could contact the site owner if he'd do a group buy.
