direct swap comes with a 72v batery and a 72v battery charger as well as a 16t sprocket kit. This package adds 20%. More power to your 60v machine. Riders are reporting close to 50 mph and a much stronger and longer power band allowing more corner spreed and drive off of larger jumps and up to 20% longer run times. You can still use your 60v battery and hot swap on the fly for all day fun
