Hello, I’m asking about how I can get my Razor MX650 to get up to 26-28 MPH. I’ve looked into 60v but I don’t want to cut pieces and I don’t have the right tools for that. I just want to be able to at least hit 26 MPH without spending over $200. I still want it to be able to last a long time while riding too, but I still want to get to 26. I’ve looked everywhere for an answer but I can’t seem to find something that I can afford. If I get 3 new 12v 12ah batteries and a 13 tooth sprocket can that get me to my goal? I’ve also seen there are ways to increase the speed by 3-5 MPH, but I want to find a way to go 9+ MPH faster for a relatively cheap price. I also looked into getting a new 12v 12ah batteries and a 13t sprocket but I’m pretty sure it’ll just increase the max speed I currently have now by only 3 MPH. I just want to find a way that could make it go at least 9-10 MPH faster.

Re: Razor MX650 Speed Upgrade.

The monetary balance doesnt meet the criteria of your goals which are pretty steep on both accounts....$200.00 will just get you the batteries and maybe half of a descent controller..

Best setup would be to get a 36v brushless motor and overvolt it to 48v with a 48v 2kw controller and it will boost the motors speed by 750rpm's the most then you can add the larger front sprocket to gain close to the rest of the speed to get closer to your goals but without spending atleast $600 youll never meet them either............

What you need to do is do a 48 volt controller and throttle and four new batteries. But your batteries need to be 12 volt 15 amp hour. ( upgrades batteries because you are upgrading your whole system which will drain the batteries quicker) It'll be about a $140 for those batteries and about 40 to $50 for the controller and throttle. That should net you 6-7 miles per hour faster. Then you could change the front sprocket for a few more, but when you do that then you're going to start heating up the motor and lose low and grunt. There's always a trade-off. You would probably be happy just doing the 48 volt kit. At least for a while.
