I have to say I am very impressed. Some other guy made a guide to adding a 50cc without welding anything and it was a clean build - but prob spent way more than you guys. Plus this just shows skill. Very cool.

[@IdahoEagle77]

A 50cc engine will cost you about $45. I highly doubt it cost more. I can do a gas build with a $170 200cc engine and hit 50mph for what It cost to build this electric bike in this video.

[@Funkyguitarcovers]

@@IdahoEagle77 motorcycles aren’t even worth it because the car drivers treat you like 💩 and cut you off. that’s how I ended up with my broken leg 🦴 i’m about four weeks away from healing, which means I’ll be able to start riding again. Now do you honestly think after all this I went through that I’m just gonna hop myself on another moped or a motorcycle ??😒 hell no !! I’m gonna stay my ass out the way in the bike lane on one of these nice powerful electric bikes or Surron and ride dat whoe on the sidewalk if anything 😂😊🏍️

[@IdahoEagle77]

@ Yes, other drivers can be careless, and I’ve known people who lost their lives on motorcycles because of careless drivers. However, Sur-Rons and other electric bikes can be just as dangerous. There are countless stories across the U.S. showing that riding an electric bike in a bike lane can be even riskier. On top of that, the significant EMF emitted by the battery between your legs while it powers the motor is dangerous to your health. Studies suggest that even carrying a phone in your pocket can lead to groin hernias and testicular cancer. I’m not taking that risk by getting on an electric bike for any sort of length of time-I’ve already developed two hernias because of magnetic fields. Many others in the IT industry I’ve worked with have faced similar issues.

I have a 3kw motor, same vevor kit. I'm using overboard batteries and xt60 adapters to splice everything together. I'll eventually buy a solder kit and actually wire the batteries correctly. This all is going on a mx650. I'll be drilling holes in the frame because of those screws. I'm kinda new to all this, so I hope I don't mess anything up.

[@BRichSolution]

I would not drill holes in the frame especially with 72V / 3000W; recess the 2 screws in the motor see video 8:00 mark

[@TURBOMOOSE]

Sounds familiar..... is this who I think it is lmao??

[@TURBOMOOSE]

As B rich mentioned, unscrew the bolt, recess the screw head on the plate and repeat for the other two just in case you need to play with fitment. The screws will then sit flush and you can cut, grind or leave (if you have clearance) the extended screw ends off the opposite end.

If you use the 20ah version of the battery how far do you think it will go before it’s dead?

My bike is all strapped up and I don’t know how to turn it on. I am wondering if it is because the other piece that’s connected to the on off switch inside the SX 500 cover has nothing to connect to it or if I made an internal mistake wiring or if running the battery T connector straight to the controller like you showed in your test was a mistake when I used to do a different way like your other videos with the MX 500/650 the T connector from the battery and the initial wires that include the fuse.

Great video! Did you have to tap new threads to mount the new motor? I can't quite tell what you did from the video. I've head that the spacing is wider on newer motors. I've also heard that the 1000W or greater motors don't have recessed bolts.

[@BRichSolution]

New rotors bolts same thread as stock threads. No drill or tap required…bolts right on. As for the motor 2 screws need to be recessed as show in my video. If you buy more expensive kits the bolts will be recessed

[@lynngeorge1762]

@B Rich. I’m using the links you provided and when I go to eBay for the 48v lithium battery it makes you select for type of motor it will be used for, the only selection available is for the

[@BRichSolution]

1200w battery is sufficient 48v with 30A discharge

[@lynngeorge1762]

Thanks for the quick response! If I just start with the upgraded battery first, do you recommend anything else since I have the bike apart? Like the heat shrink or anything?

[@lynngeorge1762]

I finally got everything in to upgrade to the 48v lithium batteries you had linked using the stock controller and motor. Which video of yours is the best to use showing the steps to install this please? Thanks

[@austinhoover7696]

Do you need to buy any thing extra for the brakes Like do you need a new disk

[@BRichSolution]

Yes new rotors to fit new brakes. Links in description

[@evananderson2918]

If I use the throttle with the key start, I wouldn’t need the “jumper cable” to start the system while doing the bench test correct?

[@evananderson2918]

Because I would simply just turn the key and the system would turn on right?

[@BRichSolution]

No, connect the key wires to elock port on controller and no need to factory on/off switch. Make sure to wire 3 speed permanently in high so top speed is 33

[@OliverMunsell]

Hi, I have a question what if have some wires that dont go anywhere. do I leave them or use something.

[@BRichSolution]

Yes leave the empty harness empty or put some electrical tape over them to prevent moisture

[@OliverMunsell]

Ok, thank you@@BRichSolution

[@stevusbeefus]

used this guide to build mine and it works great, thx man

[@BRichSolution]

Glad I could help others out as that was my intention

[@jingostanklong1265]

How long did this take to build?

[@stevusbeefus]

@@jingostanklong1265 about 6 hours to strip it and install the new motor, controller, and battery (along with the throttle), and probably spent another like 12 hours installing brakes, plastics, rotor disks, keyswitch, etc

[@jamesobrien6855]

I wrapped the whole battery up in that foam and wrapped it up good with duct tape. So basically it is covered all the way around with 1/2 of that foam that came in the box and completely wrapped and sealed in duct tape. What do you think? Could it possibly get to hot and maybe catch fire or blow up? Thanks.

[@BRichSolution]

I left some of the ends open to vent and breath a little

[@Ronzerss]

What are all of the tools you need to assemble it all together?

[@BRichSolution]

Metric hex keys for removing plastics and motor Screw drivers Wire strippers Hacksaw for cutting motor bracket Drill and bits to sink motor screws Heat gun or solder to connect wires

[@Ronzerss]

@@BRichSolutionThanks a lot bro 🙏

[@hibby5793]

Great vid, I was planning to try this out and follow your video but was wondering if you could just use a standard drill bit to recess the screw holes or do you need a special one.

[@BRichSolution]

Yes, standard drill bit it what i used. The aluminum drills out very easy.

[@Razor.racing]

What size drill bit did you use and what happens when you recess it , is it just making the hole deeper ?

[@lukez3501]

Can u just use electric tape for connecting controller too battery

[@BRichSolution]

No, do NOT use electrical tape or wire nuts as there is too much amps. At least use a butt connectors

[@grahamemerick4548]

Are the wires that go into the e lock the 2 large wires that come out of the on off switch?

[@BRichSolution]

Yes

[@Bingus2445]

Where does the single yellow wire go that comes with the throttle? Is it important?

[@BRichSolution]

Single yellow wire is for the voltmeter. Not needed but nice to have so you know battery level. Wire the yellow to orange on the controllers indicator harness

[@JosephYuma-o2i]

I know I keep asking you more questions. But I’m not getting any power now. Ride it yesterday and then it just stopped working.

[@BRichSolution]

Whats the voltage on the battery? Controller will not work unless 41V. Could be a wire short

[@Orvontix]

would it be fine to add the upgrades to a mototec? just the performance upgrades i have the 48v pro version

[@BRichSolution]

Yes you can add this to mototec 48v but you may want to upgrade the batteries if mototec don’t last long

[@DHandyFamily]

So no detail or info on what drill bit you used to recess the screws on the motor?

[@BRichSolution]

What ever bit is larger than head of screw. I believe it was 1/4” bit

[@DHandyFamily]

@@BRichSolution it was 5/16th thanks

[@cooperhigginson3255]

My bike has worked great but recently there is like a short in my bike and I don’t know where it would be do you know any possible places where the shirt would be?

[@BRichSolution]

What connectors did you use? Take battery cover off twist the throttle in dark garage and you will see blue spark

[@samgriffin1763]

Is getting the 20ah battery a good idea or should I just stick with the normal one?

[@BRichSolution]

If you can afford it get 20Ah

[@steezben319]

If you are still responding to comments on this build... if I use the stock motor sprocket and use the stock chain it will be snappy (good for wheelies, 32mph according to you) will it still be a comfortable ride when not doing wheelies? I just don't want it to be so snappy it throw's someone off the back... thank you for the help and this great tutorial.

[@BRichSolution]

It will not throw the person off you’ll be good

[@gavingg4761]

Is wiring the 3 speed throttle a pain thats the only thing i dont think i can figure out and the step down bit 😂

[@BRichSolution]

you can use the single speed throttle and wire the 3 speed harness to remain in high mode. As for step down transformer is not need if you use this headlight and taillight can handle up to 60V amzn.to/45xq5Lz

[@brandonandkrissy10]

My drive sprocket is on the other side. So my motor would need to be placed in the other side. That means it will go in reverse on throttle. How do I change that on the control box?

[@BRichSolution]

Controller has reverse option

[@brandonandkrissy10]

@@BRichSolution but reverse only gives 40% power

[@ivanherrera7171]

Excuse my ignorance it they haven’t thought me this in school, why is it important to read the voltage and how do you read it ?

[@BRichSolution]

voltage is import as you know how long battery will last. 48V fully charged is 54V and will cut power at 41V

[@_Razonster]

And also how did you connect the on/off switch to the side panels you didn’t show that in the video or do you just unplug the battery

[@BRichSolution]

See video at 28:57 for connecting on/off switch

[@Luke_btz]

How do u drill and resess the screws on the kotor

[@BRichSolution]

Use drill bit a little bigger then head of screw and drill aluminum 1/8 inch deep to recess the head like video shows

[@zitera4190]

I have a question, if I do not have enough money can I just buy the motor and install that then install the other stuff later on?

[@BRichSolution]

Opposite. Install 48v battery with stock motor and controller. kzbin.info/www/bejne/r6iaqGOsf9eKmas Then upgrade to 1800w or 2000w motor later.

[@roccocanniff3092]

how do i get the original black connectors off the 3 speed, do i cut them? i’m confused

[@BRichSolution]

Pull wires out of black connectors or cut the wires

[@calebstuart5424]

How did you splice the yellow throttle wire to the red wire going to the step down converter?

[@BRichSolution]

Used a butt connector: one side was + from indicator harness from controller the other end of butt connector put both wires (yellow from throttle and step down transformer wire) in connector

How do you do the Elock part? I know you mentioned it at the end of the video, but you never showed us how to do it.

[@BRichSolution]

collect the 2 wires coming out of on/off switch on the razor to 2 wires on the elock port. If the switch turns on when it off then reverse the wires.
