Review on Enhance Your Riding Experience with Go Cruise GC-A1BK GO CRUISE 2 Universal Throttle Control System in Sleek Black by Oren Perry

Having two hands free to adjust or stretch is great on long rides. Just notice the difference between Cruise Control and Throttle Lock. It doesn't record your speed in miles per hour, instead it keeps the throttle in one position. Even if you don't realize it, you're constantly making hundreds of minor throttle adjustments while driving. On a flat road, you can block and continue at the same speed. When you go uphill, you slow down, or when you go downhill, you speed up. You also need to turn the throttle down. It's not just "unlock". You twist the throttle, push the throttle so it hits the brake lever, and that push holds the throttle in that position (after the tension is set properly). To "unlock" you have to turn down. All in all, it's great for long trips. or cold trips. where you can let go and put your hand inside the motor to generate heat.
