Trek Fuel EXe all models
Description
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 e-bike 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 the Trek Fuel EXe a dual planet configuration is mandatory to avoid errors during low speed pedaling. Dual planet configuration brings the ratio of the PLANET3 down to 1,5:1 (halves it) making your speed limit 1,5 times higher than stock (~38 km/h for the EU/UK and 30 mph for US spec e-bikes) but bringing the rear wheel rotation speed closer to the “realistic” range which the motor expects because of the firmware protections implemented in the TQ motor.
Contents
1 x PLANET3 device consisting of sun gear, ring gear, two planet gears (with an N52 magnets) and external, position-checking magnets.
3 x M5x10 ISO 14580 bolt with pre-applied Loctite 268
