QS138 90H 72V IPM PMSM Mid Drive Motor Kit

The "4kW" 90H model of the qs138 family is the most powerful of the bunch. Sporting a longer overall length means a longer rotor which in turn means more torque. This motor is well suited for larger power sports applications or high duty cycle situations like Karting that require that extra torque and endurance the 90h can deliver. 

That's not the only new addition to the party! The Votol EM-150/2 brings all the performance of the original EM-150 but in a smaller form factor. This Combo is great for any medium-sized motorcycle on or off-road and is capable of up to 16kW Peak.

If you're looking for more power take a look at the all new EM-200/2 Controller that brings the power up to an astonishing 20kW Peak! This Combo is ideal for larger wheel motorcycles and Karts that need big bike power but in a form factor that will fit into the space constraints of your project.

If you're looking for more power take a look at the all-new EM-260 Controller that brings the power up to an astonishing 28kW! This Combo is ideal for Competitive large wheel motorcycles or Karts that require massive power and thermal capacity to nab a spot on the podium.
