Previous owner purchased from Mal (aka pacemaker, aka gatekeeper). This bike has served its purpose for me and it's looking for a new owner to take it home. This heavy beast comes with original battery pack wired by Mal (just stating where batteries come from). New black battery pack and a new black battery terminal was added not wired to setup (as a backup), Battery upkeep charged every month to ensure quality. I installed new throttle (tag/pas becomes on/off switch), 2 new sets of keys with locks (1 set for blue battery & 1 set for black battery). Back rack switch not connected. Engage controller by pressing red button to turn on. Charger included.
