The AM
Toughbox is very similar to the
AM Single speed.
Main differences I noticed are the alignment of the shaft (centered on toughbox), polycarbonate plate to mount motors to, and no nylon washers on the inside.
Same 12.75:1 ratio as the AM Single (and banebot last year), Can use 2 cims per gear box (hardware for 1 per gearbox included, must order more for 2), and all the hardware seems to be almost identical to the AM Single.
The Toughbox is roughly 2.5 lbs (our scale) compared to the 3.1 from the AM single.
