Super bad ass!! Great build. I just had a son and my mind is brainstorming all of these cool projects. Your son’s MX350 looks dope. Looks like he thinks your an awesome dad, too
your welcome dude! how do you dial the speed down? i just got one for my son and been thinking of ways to limit the top end speed to about 8mph to start him off... any suggestions would be great thanks... HAZEYDAZE : )
@@HAZEYDAZE I installed a TDPro speed controller with a proper throttle, then you can get a 5ohm potentiometer and wire it between the throttle signal wire and the throttle input on the speed controller. It limits the maximum output voltage from the throttle, and effectively limits top speed.
I’ve been searching instructional videos for people that have done your project! This is by far the BEST on UA-cam I’ve come across!!! Vinyl wrapping is actually something I’m also looking into! Even thinking about vinyl wrapping my KTM now lol My thought is to use Lithium ion 20 V drill batteries, mostly because I already have them and would not be an additional cost. would this be the same as what you did with the hover board battery? The wheels on the used bike I just picked up for US$50 also have surface rust just like this one. I’ve started trying to polish it out but I actually like your idea to paint black. Looks better and will potentially use up less elbow grease. One thing I have not been able to wrap my head around is the necessity of upgrading the razors computer to an aftermarket instead of just hardwiring the batteries in. What’s the deal with that? Thanks man
Hey bud, thanks for the reply! Would love to put more detail in about wiring them but would make it an hour long haha. I was surprised how manageable the wrapping was, however next time I'd love to use a temp controlled heat gun so I don't overheat sections. Drill batteries are good, but a 20v one will have a peak voltage of about 21v while a stock 24v lead acid battery from a razor will have a peak voltage around 29v, so changing to 20v lithium will give you less power. The only benefits would be lithium is lighter and quicker to charge. You could potentially run a pair of 20v batteries in series for 40v though The reason for the controller is that the hand throttle can't handle the full current of the motor, so the controller outputs the high current. Also a half decent controller like mine lets you modulate the speed rather than on/off like the standard mx350 one :) hope that helps!
Because the razor controller is 24v and amp limited if your upgrading to 36v you need more voltage for speed and amperage for torque. Also it dosent work with variable throttle. And you can't teach kids about throttle control with a throttle that is just an on off switch.
@@carinaserna6720 The signal wire from the throttle is wired into the middle contact (the wiper) on the potentiometer, and the throttle signal input on the controller can be wired to either one of the outer pins on the potentiometer.

Hey bud, you need a second Battery wired up in parallel. I've done that on mine, I got an xt60 double adaptor off eBay so I could connect two in parallel and I have twice the run time. Make sure you don't get a double adaptor that puts the batteries in series or itl double the voltage tho!
@@dantejimenez2679 Here is the item I purchased, which was stocked in Australia. You'll find similar on Aliexpress or Amazon. www.ebay.com.au/itm/122643045960
Hard to say without seeing your whole setup, but the throttles are often direct plug into the speed controller if you bought them as a combo. the throttle has 5v supply, a signal wire and a negative(ground) wire. You should be able to match them up to the associated wires on the speed controller. is there documentation where you bought the throttle and controller?
Hi good job, After a year, is the motor still ok ? Beacuse this is a standard 24v 350W motor right ? Also the link to the controler is not the right one ^^.
Motor is still going great about 2 years in :) yes it's 24v, and I believe they're actually only 250w despite the model name. I'll check the controller link, thanks :)
Hey so I did this paint job exactly the same you did but now it’s not working when I put it back together,and it was working perfectly fine before,do you have any idea of what the problem would be?
@@NathanielPino Hey mate, too many things that could be off, get a multimeter and check where you have power. I think the power switches are unreliable
I used a 5kOhm potentiometer from an electronics store. Wired the signal out of the throttle into one of the outer pins, then wired the middle pin to the throttle input on the controller. Which outer pin you connect to will determine whether speed increases when you turn clockwise or counterclockwise :)
Check out the Modified Razors group on Facebook, theres a lot of smart folk in there :) One guy has turned one into a bobber, and I think there's been a couple more projects similar. There's also an Indian branded Razor cafe racer available in the US!
Nah you'll need a 36v lithium charger, so I bought a hoverboard charger too, and you may need a charger connector too. I had an adaptor to go from the smaller hoverboard plug to the larger mx350 socket so didn't need to change the charge port
@@jeffyboye9739 yeah the charger I'd bought had a short lead that adapted from gx16-3 (the mx350 socket) to gx12-3 (the hoverboard plug) if you're lucky you may find the same :)
Firstly well done with the blacked out version! Thinking about doing this myself for my daughter and had a couple of questions... 1. What Ah is your lithium battery and how long is the ride on that size battery? 2. Do you run it at a full 36v and does that heat the Razor motor up much given it only 24V? 3. Did you mount the potentiometer somewhere? 4. Where did you get the cool green readout! Thanks for any answers! Cheers!
Cheers Mark! 1. It's just a 4.4Ah hoverboard battery 2. It runs at the full 36v and I've not had any problems with it overheating. It'll bog down with me riding it, but keeps going! 3. Potentiometer is hidden next to the voltmeter so the kids can't play with it 4. The voltmeter I just got off eBay. I think search 36v 48v battery monitor :) it's programmable to the battery type and voltage :)
Just off eBay, this is the particular one I bought, then a hoverboard charger, charge port, hoverboard battery and an XT60 connector. www.ebay.com.au/itm/36V-800w-Brush-Controller-and-Throttle-Grip-For-electric-Scooter-ATV-Go-Kart-AU-/122643045960?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=705-154756-20017-0
So we did 36v 800w controller. Got to 28 at first with my kid. Only 23 with me. Swapped in a 90 rear for more Torques and a front rim break for safety hits around 22 23 with either of us and Champs hills for him
Do you know the run time on it with this setup. I am really interested in the proportional speed control that the controller and throttle have to offer.
I haven't actually been able to do a test yet! We don't get to take it out all that often, but talking theoreticals, 250W motor overvolted will peak at around 425W. 36v 4.4Ah battery is about 160Wh, so 160/425 gives you around 0.35 hours run time if you were at peak output the whole time. That may or may not be helpful haha!
Hey there! The Hoverboard batteries dont have a dedicated charging circuit, only through the XT60 connector, so you use the Charge input on the Controller, which connects to the battery connector on the controller.
Thanks for the reply. Are you also talking about using two batteries. I will buy two. Thanks for inspiring us. I even painted the motorcycle the same color, only for the matte color on the plastics, I used rust oleum universal color flat soft iron.
i got the tdpro 36v and im trying to wire everything up with the stock batteries till i can get the 36v lithium batteries i got some questions you think you could answer?
@@conroe_au so i wired up everything motor-battery-throttle-brake- and the power lock is just jumped. 25v going in and nothing coming out the throttle end motor end or any other wires
@@seabassgt7998 Hard to know without seeing your parts and how you wired it up, but have you tried all combinations of power lock and brake switch on and off? does the motor work when wired direct to the battery, bypassing the controller?

I'm on the stock motor and still haven't had any trouble! I've not ever checked motor temp, but it's never ridden like the motor was overheating, even with approx 90kg on it. Doesn't have much guts on grass or up hill with an adult on it though
