Bike needs a bigger motor for an MX bike but I will burn this one out before doing the upgrade. Bike has room under the seat for another 4 packs of 5.8ah lithium. Needs a motor and controller that can run at 90 volts and 600 amps peak. That kind of power would bring the performance closer to an MX bike.

Still, its a fun ride to be checking the acreage in stealth mode.
