I got a 1800w kit off Amazon with motor, controller and throttle. I reused stock sprocket off the old motor. I also pulled the screws out and counter sunk the case so that the screws go in flush with a dremel and about 15 sanding wheels. Then put the bolts back in and chopped them flush with dremel cut off wheel. I am running 48v lithium batteries and reused stock charging port with a new charger from amazon. It has a lot torque off the line. I also swapped in mountain bike hydrallic brakes I had laying around. Next mod is rear shock. Thanks for all the info on the suspension upgrades.
Thanks for taking the time to make these videos. Not wanting to mod my frame in anyway I turned to modding the motor case. Real easy to do just pull the case apart, countersink the bolt holes then slap it in. No mods to bike frame...
I've been wanting to do this to a RSF650 for a while now but I know I wouldn't be able to ride it around my town.... So I'm going w/ a Razor Mx650 w/ the 60v 2k kit but I'm adding a 3 speed switch that way I can tow my son around in his bike trailer but also rip it around when I'm alone.
Ive seen alot of comments asking if it will fit there bike. electricscooterparts.com has kits that will fit MX350 and MX400. They also have kits that will fit MX500, MX650, and SX500.
so i have been doing a lot of research and I think this kit that you showcase here is my best option for the price, I'm just struggling to figure out what amperage battery to get to go with this kit. what did you use if you don't mind me asking?
Merci pour la vidéo, jai exactement le même setup de moteur sur une moto style mini baja, ca roule sur le stand la roue en l'air mais des que je le met au sol avec du poids le moteur na aucune puissance et donne un son de de moteur qui aime pas ca du-tout et de plus les fils du moteur deviens chaud en quelque sec mais pas sur le bench test , sur le bench test ou la moto sur le stand tout roule a merveille. Donc pansant que cest le moteur ou le contrôleur qui es défectueux , jai acheter le même model en 48v 2000w et meme chose, vous avez eu se problème ?
Regarding the starting torque ("torqy-ness"), couldn't you use a "speed switch" with the controller's "low, medium, high" circuit to change the effective starting torque?
Hey would you be interested on doing an exact build for mx650, I’ve had it parked in my backyard for 4 years. It would be a nice project to get started on before summer.
You should have just took some steel bar stock and made a little adapter for the Mount. Then just use spacers and washers to flush it up to the adapter and install it to the factory mount. That way if you ever need to go back to the original you can. I know the chain alignment is a concern but the riser adapter would have shored up that slack in the chain too.
Wow thanks for this. Am doing a conversion of an old moped to electric. That moped probably weighs 150lbs max without me riding it. Was wondering if realistically I could use a similar conversion kit of the same power to get it to cruise around 25mph and go for about 30miles with a 48v 20ah lithium battery? Thank you. Would appreciate any help you could give.
I would say 48v 20ah probably good for 20 miles .. not sure about 30. My MX650 is 75 lb. I think the moped conversion could work, just not sure how much fab you will have to do.
@@TimArmbruster Thanks for the reply. Alright, i can start with 20 miles, I'm good with that. Already did the planning and math for the fab work, will probably make a compilation video, to help other's out when I'm done. Thing is though, at 75lbs, my moped is way heavier than your bike, but i will be running it on relatively flat terrain, maximum of 1.5% grade maybe. Im hoping it'll be enough. Just doing it as an around-town cruiser, and to showcase the technology here in my hometown. Thanks again for the help.
Hey Tim. Thanks for posting all of your Razor videos. Are you happy with 1800 watt kit from electric scooter? It seems a bit more expensive than piecing the parts together from Amazon or Ebay. I do like the idea that they mark and test everything before hand. What are your thoughts? Worth the extra dollars?
Thank you. For me, I was happy. Lota of other people have success with eBay kits but I haven't tried them so hard for me to compare. For me the price was worth it for peace of mind and support. Installing was very simple once I figured out what to do.
@@TimArmbruster Thanks for responding. Do you have any suggestions for a replacement fork that will work with the stock front tire. I saw this mod on www.pocketbikeplanet.com/threads/mx650-mods.31100/page-102#post-912367 but I feel like I'm missing something because the bearing size seems wrong.
Would this work on a sx500 bike from Razor? Just wondering because I’m looking to put one of these on mine instead of buying a whole new bike. Implus it would be a lot less expensive.
Yes, the kit is compatible with SX500. Here is the list of kits from electricscooterparts.com cart.electricscooterparts.com/SearchResults.asp?search=mx500+mx650+sx500+modification+kit
Can you give me an update for using the stock chain and stock sprockets? Are they holding? I am doing this built but I don’t want to use their bigger chain and sprocket
So at 48v, what is your top speed? My 48v SLAs on the stock 650 motor is doing 25mph. If I do this (minus the rear sprocket) I hope I get a noticeable speed gain. Great video man!! A1
Good Question. I need to do a speed test and I will get back to you. My gut instinct is that it is not a lot faster than 25mph, but you could change the sprockets to get it much faster. The setup with the kit is very torque-y, and I think a smaller back sprocket would work fine. I like to ride them on dirt tracks, so I've found I like the torque-y-ness vs. top speed.
Hello Brian, I'm not sure I understand the question. If you are asking if the stock brake calipers fit on the mountain bike; no they do not. It is a completely new front brake caliper, rotor, level, cable, etc.
Hi i would like to put the RM80 front fork on my MX650 for more height since i have a 12in shock in the rear. Would this work out and would it be a direct fit or alot of mofications? Thanks to anyone who can answer
Doubtful that would work without cutting and welding. Here is a video of what I did to upgrade forks. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-V6NH6DDAPv0.html . My method can get a bit pricey, but produces a legitimate performing shock if you want to jump it or ride on a track. There are others who have purchased longer springs and bolts to modify the height, but it won't produce a shock that performs as well. It does raise the height, however, if that is what you are looking for.
If I were to purchase 48v lipo and use it with stock sx500 36v motor and system how long would it last before blowing the controller and motor? If I can get a few rides out of it before they blow I may do that then get the 1800 watt 48v kit.. ?
I'm not sure about that, but I do know that people overvolt them successfully. I think I would buy an overvolt kit off of eBay. I think they are about $50. At least then you would have a controller that is designed to handle 48v. I suspect the motor would be ok.
so with the stock sprocket and chain what was your average top speed??? i recently bought a razor RSF650 and i want to upgrade it for sure, just doing research...
MX650 Rear Tire Change and Fresh Look! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oW36kI0CWYM.html Tips for replacing the Razor MX650 or MX500 rear tire, which is a royal pain. I'm also painting the back rim and adding some spoke protectors for a fresh look.
Hello, I did a bit of research and you are right! The sprockets that come with the kit have an 11 tooth front sprocket and 72 tooth rear sprocket. The stock sprockets are 11 tooth front and 80 tooth rear. So, I substantially slowed it down when I switched to the old sprockets! I'll order a new larger front sprocket to compensate.
Just ordered a 12 tooth and a 14 tooth front sprocket to try. The 12 tooth should make it very close to the kit ratio, and the 14 tooth I ordered just for fun. I'll do a speed test on all of them and post a video.
Range should be approximately 20 miles. Tough to say because I ride it mostly on dirt tracks. Speed is between 23/24 mph and 27/28 mph (vs 16/17 mph on a stock mx650) depending on what gear ratio I am using. I will post a video on the speed.

@@TimArmbruster reason why I asked is because I have a 1000w 48v uberscoot n im changing to lithium 48v 20ah n wanted to know can I put same 30amp fuse that came with my lead acid batteries the lithium does have a built in 30amp fuse and BMS..is it necessary to install fuse on positive wire on lithium
@@TimArmbruster hello again I have a question.. a voltmeter with positive n negative how would I install on my scooter do I connect positive n nagative to lithium battery then from there connect battery to speed controller with volt meter connect to battery by the way the volt meter only has 2 wires red and black my battery is 48v voltmeter works from 12v-60v
@@loyaltyovermoney5942 I connected the voltmeter in parallel with the controller. In other words, wire the voltmeter positive and negative directly to the battery positive and negative, with a separate fuse wired in between one side. The controller will also be wired directly to the battery, also with a separate fuse. That is how I did it.
I did a video of Replacing Brake Pads and using Disk Brake Quiet to Eliminate the Brake Squeaking ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dmmRDYZjCJk.html
So this kit is marketed as being able to install it without frame modifications but clearly requires them? How on Earth could they miss that when making the kid or are they just shitty greedy manufacturers?
