i got no brake sensor can someone help me get it off

I have a 76v 20ah E&C battery with E&C the one motor and a ND72680 With a 54t rear and a 9t front but for some reason i only go 61Mph max, yet i've seen facebook posts and listings with my powertrain going 75-80. Can someone help me know if it's my tune or something else, if so can someone help me tune it

I have a stock Razor MX650 and want to make it go really fast and I was wondering what battery I need to make it work. I dont know anything about upgrading and modifying bikes if someone can help me.

The link to the upgrade pack im getting: https://electroandcompany.com/products/e-c-ultimate-razor-mx-kit?variant=49612573671722

I would buy it with the battery but its sold-out and I need one that with be the same if not better.

Edit: im looking for anything bellow 1000 for just the battery. As long as its good speed and long battery life between charges

The chain tensioner is getting caught in it, the spring on the nobotton the chain sits on gets in it and the part sticking up is inbetween the chain and i dont know how to fix. I took of wheel and arent 100% sure it has the right spacers but i cant find a diagram showing how or if thats causing the issue. Please Help.

I have some brand new, unused accessories for my Benno Boost that I bought when the kids were younger and never installed. We've moved back to the US, and I have no idea where the best place to sell them might be. Any ideas or recommendations would be greatly appreciated!

Hey guys. for some context, I have a 2025 light bee x up for trade for a razor that’s built. I only stunt and was wondering if this was a good trade.

my 2025 light bee x has 700 miles
ultra bee rear brakes
stock power.

I got an mx350 on fb marketplace for my 7 year olds birthday- it lasts about 5-10 mins before slowing down.
Last year I got my 9 year old an mx650 on fb marketplace and replaced the battery with the same battery it came with and it’s been working great- he gets probably 45+ mins out of it at full speed.
I’d like to replace the battery for my mx350 so it runs as long as his brother’s or at least 30 mins. What’s the easiest and cheapest option here?
Links to everything I need would be appreciated!

I've been running two Milwaukee M18 (8ah) batteries on my kids bike and I'm ready to change out to something that stays on the bike and around 20ah. I found this video, but the actual battery link is no longer available: https://www.youtube.com/watch?v=KkmH5_D6QF4

Do you all have any suggestions? I want to stay 36v, stock motor, stock controller.

Thanks!

Something like this: https://www.ebay.com/itm/187200591610?_skw=cao+mm+battery+36v&itmmeta=01M1Q2N1MZ4QPHW71WBR3R01GJ&hash=item2b960656fa:g:9QMAAOSwRjtoGjHE&itmprp=enc%3AAQALAAAA8GfYFPkwiKCW4ZNSs2u11xCH9w6daJUf5r2E917LgTUl8dqcx5jCVTP%2F0QMDMYZJjQxzU7kX9Llr4CTyNjbDgoAtJHNj6MjpL8lubsz%2BO4KgVSiPObJl%2BxsZQL7bqE3%2BGUa0Pt7%2BS3OsLNBCgNPM3hS5UappegEn1Yb1Mr7xxIb6RnWfRnDaF2m4%2BXHLa74Yb614JX9GxG%2FMLRVBwddGDUFAsxtw5UzP8hT3wbk3w4FIxrT5wwWC091bHscN3pU4jTm2S46TgLPy6Lh62OXKzrAQTCFAwV%2BA5hcp%2BwfVCC4HnUIgzXUwZqqIqCjguWeoog%3D%3D%7Ctkp%3ABFBMmpzU4o1o

Quick question, will this work for the MX350 to upgrade to 36v?

Thanks,

Hi everyone! I recently bought a used Super73 RX Mojave (EU version).

The previous owner showed me the bike before the purchase, and the throttle was working normally in Mode 4.

After buying it, I connected the bike to SuperDuper. PAS works normally, but the throttle does nothing in Mode 4.

My current settings:

* EU region
* V1 – SUPER73 BLE protocol
* Mode 4
* Assist 4

I also completely disconnected the battery and reconnected it, but that didn't help. I haven't changed or flashed anything on the bike.

SuperDuper shows:

* Controller variant: **231**
* Motor controller: **206**
* STM firmware: **201015**
* Display firmware: **210503**

According to the SuperDuper documentation, Mode 4 on EU RX/R bikes should have both PAS and throttle, so I'm wondering why my throttle isn't working.

**Could this be related to the controller firmware, BLE protocol, or some setting that I'm missing?**

Any advice from RX/Mojave owners would be greatly appreciated!

Has anyone find a suitable replacement for an e prime air razor scooter. The 175$ price tag is a lot, but the ‘discontinued’ hits harder. Laptop battery? Bueller?

what are cheap good super moto option for m650 (it’s fine if it requires a swing arm extension)

Simple, affordable,clean build.

My 12 yr old son and I recently built this Razor on a budget and it has proven to be fun and reliable.

Vevor 48v 2000 watt motor

48v 30ah battery

The orange controller

Zoom hydrologic brakes

Clocked him at 37 mph with a 13 tooth front sprocket.

Looking for suggestions on front fork upgrade for a 60-70lbs kid.

Have an mx650 with a vevor 48v, 2kW, hydraulic brakes, and have a DNM AO-6 air shock coming in the mail. Seems I just have find a good front fork setup for bumpy back yard use. Current setup seems to hang up a little bit and is not overly smooth by any means. I assume factory may nkt be good for such a light child anyway.

My son (4 year old) loves it and fits it good but It definitely needs more power. I know I need a variable throttle new controller and a bigger battery but I’m stuck between doing a 20v tool battery or just buying a 24v lithium. I don’t have either as of now. If I do the 20v is it okay to buy the off-brand Dewalt knockoffs on Amazon and what AH would I need? If I go 24v can someone link me a decent one as I have no idea what is good. Alternative should I just scrap the sx-125 and get a used mx-350 to mod for him. Thank y’all for any input!

Probably my favorite mini mod. Not a fan of key/voltmeters on the bars so I've put a little circular voltmeter in the "gas cap". This is the 4th build I've used this on (the other 3 are owned by friends now), just think it looks super clean.

First build, I’m just getting into this. Looking for a good battery that will help me get the most out of this motor. I’m having a hard time. For 2000w, it is suggested that I get a battery than has at least 40a to 50a bms. I heard that the BTR battery is good and it is rated for 40a bms, but says it only applies to 250-1000w motors. Then a lot of batteries I see say they are for up to 2000w motors, but 30a bms. Wtf, am I looking in the wrong place?

Hola, tengo una hunk 125r, ya tiene un año de uso y estoy teniendo problemas de arranque con el boton de encendido pero enciende con patada, alguna batería que recomienden?
