Yes Sir, you had stills often showing details of your wiring… that’s just one of a thousand examples of how effective your process of explaining is.

[@maxlewin7807]

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.

[@BRichSolution]

In burbs electric is must as gas will annoy neighbors

[@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.

[@Bucky15690]

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.

Love your videos. I already over-volted my son's MX650 to a 48V 20Ah lithium linked in another of your videos. Also installed lights thanks to your help. Considering getting him this motor and controller for Christmas. Any issues running the 1800W motor with the ebay battery rated for 1200W? The 35A 20Ah I got is rated for 1500W, but still under the wattage of this motor. Thanks again for sharing all this great content!

[@BRichSolution]

No issues running 48v with 1800w motor kit. I believe the battery bms states 30amp but its more like 40A as i see no degrade in performance until voltage drops below 45V so that tells me 1800w / 45V = 40Amps

[@GG6502kw]

Just asking is the heat on the battery and cables needed or optional? And also the yellow box is not available on Amazon. Any substitutions for it?

Heat gun melts the solder and waterproof seals the connection you can also use lever connectors if you don’t want use solder/seal connectors. Here is updated link to junction box amzn.to/4c4rvRI

What does the new sprocket do? Right now I’m going 28mph with stock sprocket. Also thanks for the video it inspired me to build my mx500 build

[@BRichSolution]

13T make the bike less jumpy at the start and gets you 20% faster speed. Did you wire 3 speed is high? With stock sprockets you should be over 30mph; sounds like you’re in medium speed and high gear you’d be over 30 mph. See video at 4:28

This is the best tutorial! Unfortunately, I haven’t been able To get setup to work after trying the 3 speed throttle. It worked with the throttle that came with just but won’t with three speed. I tried to plug back in regular throttle and now it won’t work either. Any help would be greatly appreciated. Ordered everything from the video link.

Does the elock port have a switch or jumper wire? You can used just the single speed throttle and wire the 3 speed in high

[@rocksolid1829]

@@BRichSolution the elock has a switch. I tried switching back to the single speed throttle but it’s not working anymore. I did originally when I tested before trying the three speed. After I couldn’t get the three speed to work, I tried going back to the single now nothing will work. Is it possible I shorted something out our ruined the controller/motor? Thanks btw! Just a dad trying to spend quality time with my boys. I have limited electric skills but wanting to learn and teach them along the way

I got it to work! Originally I was usi the quick connects before I committed to crimping. I decided to start over and do overthibg the video said. After putting the connectors on it worked! Thanks again man

Isn't the rear disc brake 140mm? When you upgrade them to 160mm does the brake set accommodate for that? Thanks!

[@BRichSolution]

When you upgrade to hydraulic brakes the stock 3mm thick rotors will not fit and you need 2mm thick rotors that are 160mm diameter. See parts list www.amazon.com/shop/brich/list/2A0OX01IQELT4?ref_=cm_sw_r_apin_aipsflist_aipsfbrich_HACDTVEAKMBVKX6M3P5T

I just got the same kit but my battery hasn’t came yet so I got a question. Is the stock throttle just plug and play and if not what do I have to do to make it work?

[@BRichSolution]

The throttle than comes with the 2000w motor kit is plug and play. The stock razor throttle is not

[@949viggo]

@@BRichSolution Thank you!

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

My son has mx125 with upgraded makita 18v power tool battery. It goes a little faster and longer playtime for him. Also looking to get a used mx650 wanted to upgrade just the battery into lithium for longer riding time as well but also keep same motor and controller. My question is 48v 20ah a good idea for it or bad? Thanks in advance if you ever or not reply. Awesome builds!

[@BRichSolution]

20ah battery option is a great idea the bike will run for a long time

Where do u get the jumper wires to make the 3 speed work

[@BRichSolution]

The jumper wire was spare piece of wire i had laying around. You can always cut off the connector and wire together the 2 wires needed for high gear

[@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

Do you just leave the charger on until it’s fully charge when it gets hot?

[@BRichSolution]

I use a $10 timer when charging to ensure i don’t over charge. Charge for 1-4 hour increments. See video kzbin.info/www/bejne/f6TaiGN7mcuSj7s

Thank you so much this helped me a lot

[@BRichSolution]

Glad it helped!

We have a throttle with a volt meter we aren't doing 3 speed so it's just throttle and volt meter. We have a Red, Green, and Black wire on the throttle all in one clip and then a yellow and blue wire each in heat clips. What is the coloring for the wires into the controller you used?

[@BRichSolution]

Blue and yellow wires go to indicator harness on the controller. 3 throttle wires go to the throttle harness on controller

[@magnifisis4859]

Will the 20 ah battery work in the build shown in the video?

[@BRichSolution]

Yes the 20ah battery will work and provide longer rider times

[@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

[@holdenfitzgerald4212]

Did the motor hall center have a red wire cut. Mine does, it’s looks like it’s on purpose but i don’t know. Thanks

[@BRichSolution]

It did not

[@tinyking4114]

do you mind explaining how the display shows the voltage? I get that you splice it but where does that connector hook up to?

[@BRichSolution]

Voltage display you can splice to any connector on the controller outputting 48V like the indicator harness or splice into charge red wire on charge port
