The APEX + Bixpy K-1 Power Motor Kit allows any BOTE APEX-compatible watercraft to be outfitted with the awesome power of the Bixpy K-1 Motor. The K-1 Motor is roughly 20% shorter in length than its predecessor, the J-2 Motor, yet offers the same massive output the J-2 motors provided in a quieter, more sleek, and more rugged aluminum housing.
