Speedbox 3.1 Tuning Kit for Specialized eBikes

Does exactly what it says it does. Takes less than two minutes to install. Certain places that we ride at 20 mph just doesn’t cut it. Bike easily goes close to 30 mph now. This is the second unit I’ve bought for my personal bikes, have not had any issues and a couple of my buddies and my brother all have installed them and they work just as they should. Five STARZ all the way.

What a great bit of kit , certainly speeds things up easy to fit simple to use recommended

This product works great. Only had a few rides on it, but works perfect.
