Thank you, B

A 36v battery pack would add some pep to its step. Could use a a/b battery selector switch to go from stock battery to the 36v battery or just wire in the 36v battery and call it done. Look into frame mount batteries and see if it will fit on the frame to your liking or conversely pick up a rear rack battery pack.
