Review on Yosoo 3 Gears Speed Switch Bike Grips Cover: LED Display Screen & Accelerator Handle for Electric Bicycle by Aaron Moore

TERRIBLE. The other day I finally managed to install it on my drift trike and as I was riding like the third time the throttle fell apart and the tune in my hand slipped off the steering wheel lost control flew away and has roll over three times. Fortunately, I was only traveling at 18 miles per hour at the time. I found the internal spring and reassembled it and it works but I can't trust it anymore. If you're using it for light slow cruising it might be fine, but not for anything else.
