As mentioned earlier, CARVON in-house hub motors are being upgraded. We now offer V2.5 with 85Kv on both our Single and Dual hubs. This means more torque, better take-off and more climbing power. The big motor pictured above is the 85Kv motor. The smaller motor is for our future V3, and it will have 116Kv. They are meant to maintain the awesome speed that CARVON hub motors are known for, but in a different configuration. We will reveal more about the V3 soon. In the meantime, check out the new CARVON V2.5 in our Store. Thanks!
