This is a pre-assembled gear drive for ease of use and possibility to ride as soon as possible!

Comes with pre-set gear meshing and initial angle (15 deg, front side).
Angle can be changed before putting this setup on the deck, (6 total positions).

Angle adjustment is not thread locked. It is not necessary, but recommended to use a bit of thread locker after setting up wanted angle.

Every other drive train screw is initially thread locked.

All bearings are pressed in using a thermal press method, not press-fit, especially not foot press-fit.
All bearings are pressed into Aluminium.

Bearing differences:

  • Straight cut gear drives use groove ball bearings.
  • Helical gear drives use angular contact ball bearings to sustain the axial loads.


Gear types and materials:

  • Wheel gear is machined from plastic (harder than POM, equivalent to aluminium hardness).
  • Wheel core adapter is aluminium.
  • For straight-cut gears: motor gear is aluminium.
  • For helical gears: motor gear is steel.

Motor fitment:

  • For FatBoy 240 hangers maximum motor size is 6355-6374!
  • For FatBoy 260 hangers maximum motor size is 6355-6384!
  • For FatBoy 275 hangers maximum motor size is 6355-6396!

Using Maytech motors or other motors with axle length <=25mm doesn't require cutting off the motor shaft!

  • Add thread lock (Loctite 648) on the motor shaft, insert the key into the keyway slot
