You are missing nothing. It is simply that the motor is drawing far more than 20 amps. Remember that every motor draw stall current when you first apply power to the motor. When you couple the motor to a mechanism that adds a load to the motor, the stall current (or near to that amount) will flow for long enough to blow the fuse. The 20 amp fuse in the Spike is designed to protect the contacts of the relays inside the Spike. Your only choice is to reduce the load on the motor or swap the Spike for a speed controller.
