How Does The Planet3 Speed Derestriction Device Work?

PLANET3 is an easily installed and reversible way to derestrict your e-bike. It uses a purely mechanical design utilizing a patent pending planetary gear set which makes it undetectable to the bike’s electronic gizmos and gives you full control over the choice of speed at which you want to ride your bike.

No more pushing through pudding after hitting the speed limit, virtually no maintenance, and no worries. Just you and your e-bike – the way it was meant to be!

PLANET3 is a planetary gear set which reduces the rotation speed of the magnet used by the wheel speed sensor three times. For every three full rotations of the rear wheel, the magnet completes just one full rotation – effectively making the bike think it’s doing 1/3 the speed it is actually doing, thus increasing the pedal assist speed limit by a factor of 3.

For the Specialized models sold on EU/UK market this translates into a speed limit increase from 25 to 75 km/h (15.5 to 47 mph), while the US and Canada models limit is raised from 20 to 60 mph.
