About Circle PLANET3

Your e-bike too slow for you? Ride it how you want it.

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 reduces the rotation speed of the magnet used by the wheel speed sensor up to three times.

This effectively makes the bike think it's going up to three times slower than it actually is, so it keeps assisting you up to a higher speed. The mechanical nature 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 maintanace and no worries. Just you and your e-bike - the way it was meant to be.
