    Alright alright alright... it's in and functional! Mx500 with 48v 20ah lithium ion battery pack is now sporting a 48v 1800w brushless motor and speed controller! Buuuuut.... it's acting weird. I got it on high setting (tried all 3) and upon hard acceleration it almost acts like a car with a...

    So out of nowhere my 48v 20ah lithium ion battery pack started tripping the bms board at anything over half throttle. I swapped the motor for a different motor, still does it. I swapped speed controllers for another speed controller... still does it. Tried both new parts together, still does it...

    Ive decided i want to start salvaging razor electric bikes that need work, buying them second hand from people who dont know how to fix them or just dont want to for cheap and upgrading them to resell to kids and adults for about what they sell for in stock condition in good shape.

    Alright so I vividly remember when power was sent through the relay at the twist of the throttle there was two clicks in sequence, first one happens right as you twist the throttle and the second happening after passing roughly 1/4 throttle. This tells me there's sort of a built in low/high on...

    Alright so I got a mx500 with 3 12v 18ah batteries that ended up with a short in the stock motor. I went ahead and ordered an 800w 36v replacement motor already and will be running it off my bridge modded mx500 speed controller. With that said I'm curious what range you can play in when it...

    My 9 year old cousin has a Electric blue razor. He’s a maniac and wants it to go faster, I told him it’s possible with the right guidance. Can someone suggest parts and leave step-by-step instructions on how to upgrade it? I’d greatly appreciate it.

    Hi I am wondering how to make my Razor Electric mini chopper go around 25-30MPH (without converting it to a petrol engine) Do I need to buy a different motor, more batteries, a different speed controller? (What do I need to buy to achieve 25-30MPH) I will be very grateful for any help Thank You
