I figured it was time to post the mx build in it's performance completion. What began life as a stock mx500 to a mx800 to an overvolted 48v mx800 with a 20ah lithium ion pack is finally a brushless 48v 1800w beast with an 88 tooth rear sprocket swap, LED headlight and taillight for night riding and poor visibility usage. With the rear sprocket swap (came off a razor pocket mod scooter) it pulls ridiculous wheelies and accelerates hard while still topping out around 30mph. All that's left to do now is cosmetic upgrades and suspension work!
