A 3.8:1 planetary gear hub. This will bring the drive ratio to 16.72:1 for the 44 tooth gear, or 19:1 for the 50 tooth gear (https://www.thingiverse.com/thing:2736589)
You will need to print 8 planet gears and bearing retainers, and 2 of everything else except the mount and mirrored mount. This replaces the fender mounts and rear rims, and can be installed without removing anything else.
Assembly is simple. Bearings are pressed into the ring (2 each) and planet (1 each) gears. The outter rims are attached to the ring gears with m3 screws (you can do this after mounting the tires to make getting them on easier). The planet gears and carrier attach to the mount with m2 screws and the bearing retainers. The mount and fenders are attached normally, and the wheel is held on with the normal hubcaps.
Needed Hardware:
12 12x8x3.5 MR128 ball bearings
16 M3x12mm socket cap screws
8 M2x8mm socket cap screws
