ebike tuning Planet3 for ROCKY MOUNTAIN Instinct/Altitude PowerPlay A30/A50
Planet3 is a non-invasive tuning device that is easy to install and to remove since it is installed into the ebike rear wheel.
Thanks for its planetary mechanical gearing system approach the magnet travel 3 x time slower than normal allowing the engine to be derestricted for speeds up to 75 or 96 km/h.
Easy to install and to remove. Virtually no maintenance is required.
PLANET3 is a planetary gear set which reduces the rotation speed of the magnet. 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 of the speed it is actually doing and thus it increase the pedal assist speed limit by a factor of 3.

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.For Rocky Mountain bikes a dual planet configuration is mandatory as it helps reduce torque sensor activation delay that was experienced by some users with a single planet configuration. This means half the speed increase (~42 km/h with a dual planet compared to ~84 km/h with a single) but almost no delay in technical climbing when ratcheting your pedals. Users are welcome to try both a single and a dual planet configuration, but the product ships as a dual by default!
