your bms is protecting your battery you should set your battery cutoff at 63v. I never start a ride with 70ish volts i always start with a full charge around 83.5v or close to full on my 72v 36ah battery and I get around 35+ miles on a charge. when I heard you say 70v I was like your battery is almost dead. yout gotta take sag into the equation
i have a electro and co 5000w kit rsf650 on 48v and i plan to go to 72v and it will feel like a whole new monster compared to the fact that the only other ebike i have had before the rsf650 is a mx350. also i got the bike used with the kit and battery so i haven't experienced it stock
I just got a used rsf 650 stock and it’s great but I plan on getting the 72v 6000w kit I’m excited about it and was wondering if you got yours and if it’s easy to wheelie?
@@Edboi1313 i didnt get the 72v battery because some stuff broke on the bike and on my computer so i cant afford it anymore. But if i come to a stop the 48v one wheelies amazing jf you keep on balance point drcent
60v is absolute LOWEST you should run a 72v batt, any lower ans you risk damaging the cells. Im pretty sure it's safety cutoff for programmed into the bms to cut off at 3v per cell. 72v is 50%, you said you started the ride at 69v, which was about 40% lol
Your absolutely right ! Never go below 60v on a 72v battery ,, but if the Bms is bypassed the cut off is no longer active . the pack will just drain unless the cells damage
Thats it i was on a off road trail and my whole front tire got submerged in a sink hole i didnt know was that deep and got stuck in mud and i had to pull it out then my tensioner bent and the chain kept popping and i slipped trying to pull my bike out
If you like working on bikes, the razor has a huge modding community behind it, so you can really make the bike whatever you want. Meanwhile the burromax is almost perfect out of the box (it would be THE perfect bike with 72v power). That said, made some poor choices with how I built my razor (don’t trust the Facebook groups). Just remember: The lighter the bike, the more fun it is to ride
@@CringeMoto thanks i appreciate the feedback on these bikes i do like to wrench on stuff and i’ll keep in mind to try to keep it light as possible if i get ah Razor . thx🫡☝🏽
@@eliasbrown2010 it wasn’t a kit, I pieced it together from multiple vendors. Motor $130 (Aliexpress), Fardriver $150 (HotPaxx), Battery $600 (Amorge), Throttle $35 (Electro and Co), Forks $100 (Amazon), Rear Shock $100 (Amazon/Fox). I’d recommend HotPaxx if your looking for something plug and play, their prices are better than anyone else.
They’re all about the same. The mx500 and mx650 have the exact same frame. SX500 frame is slightly different and comes with 10” wheels front and rear, instead of the 12” front wheel.
so are the cops allowing these to be ridden in your area? they sure wouldnt tolerate them here and i live in a shit hole town lol 3 hours from boston ma.
Big city police don’t seem to care. As long as you obey traffic rules and are courteous to pedestrians you’ll be fine. Although that’s another reason to go with more of a “sleeper” build. Keep it looking like a kids toy
@@CringeMoto the fact that my razor still had the stock plastics and stickers on it is the only reason I didn't get in trouble. I ripped it down a hill in the bike lane and I just didn't see a cop about to pull out of a parking lot. he pulled me over and then when he walked up he said, wait is this one of those electric razor things? I said, yeah you can get it at walmart and he said, alright just keep it on the sidewalk and don't go too fast and he let me go. After that I swapped the suspension and realized I can't pull that excuse anymore so I got it registered as a moped, it's got a plate now👌

no its the BMS in the battery turning off at low voltage . you should carey and charger or rope to tire to his bike and pull

60v is 0% and that’s awful for your battery. I’d say no lower than 62.4 which is 10%
You got nice pretty clean road and trackd has nough respect and funs😅😊raza
The bms cut off activated and shut down ! Why ur only seeing 4v
Hey you said your set up but what was your brothers considering it was a considerably cheaper build to go with?

Bro, we need a mop, some time you’re in Georgetown at Wolf Ranch
Do you like the 72v Razor or you prefer the Tt1600r ?

Did you figure out what was causing the voltage drain ? Seems kinda odd
I'm running a 280mm on my razor
We always have a tow strap with us haha
Definitely need to add one to the tool bag
@@CringeMoto Yeah it has saved us a few times sad to say lol .. The Ride of shame back going past the people you went by before is the hard part 😆
I was the 400th sub ❣
Hey what’s the kit you used for cuz I haven’t found any like yours
Also how much was the kit?
@@eliasbrown2010 it wasn’t a kit, I pieced it together from multiple vendors.

@@CringeMotois the reason your chain fell because your running the stock chain and sprocket?
@@Huckeys2 it’s because I removed the plastic chain guard that goes around the rear sprocket. Since I put that back on I haven’t had any issues.
@@CringeMoto do you have an upgraded chain and sprocket or stock?
What bag is that on your handlebars?
@@kauaigrown it’s the large handlebar bag from Burromax
What mods did your brother have on his pit bike and what kind of bike is it?
mx500 with shrimp depot 60v battery, fardriver 72300 controller, Kurt minto front fork lift kit, and crf50 plastics
Do you have the 72v 30ah battery
72v 36ah
Hey what brakes do you have?
51mm "DJ-Motor" twin piston pitbike brake from Amazon on the rear. Front brake is a 43mm pitbike brake from "Goofit" also on Amazon.
Ok jezza
so is the razor mx650 one of the better razor bikes to get?
They’re all about the same. The mx500 and mx650 have the exact same frame. SX500 frame is slightly different and comes with 10” wheels front and rear, instead of the 12” front wheel.
@@CringeMotowhere did you buy your sx500 from?
@@Huckeys2 Facebook marketplace for $200
Why not just buy a surron? 🤷🏻♂️
$5,000 vs $1,200. And you can’t fit a Surron in the back of your car
