The infamous QS138 to this day has little to no competition in the electric power sports market. With its v-shaped embedded magnets and finned body that provide excellent heat dissipation, Its is hard to beat. The QS138 70H is well known around the world for its ability to produce power in a small form factor. A tried and true motor that packs a hefty punch for its size and weight. This is the sleekest version of the qs138 and is always an excellent choice.
