SpeedBox 1.0 UNLOCKS the speed of your E-Bike!
The SpeedBox 1.0 system works by "fooling" the speed sensor on the bike to think that the bike is going slower than it actually is, unlocking the pedal assist power ABOVE the speeds that the original setup is limited to. For example, on a bike with 15mph pedal assist power cutoff, the SpeedBox 1.0 DOUBLES that to 30mph power cutoff! The only price you pay for this is the speedometer on the bike is no longer accurate at speeds above the original power cutoff setting. But believe us, it's MORE than worth it to have pedal assist power available at higher speeds, it's a whole new world allowing you to travel farther and faster!
Install is very easy and the unit is very small and is completely invisible on the bike when installed as it sits inside the crank housing cover on the bike. It's also completely removable at any point with no modifications to the bike required. You can install and un-install as many times as you'd like. The system can be DISABLED while still installed simply by turning on the headlight on the bike.
