Great! Thanks!!
Anyone happen to know why the motor/rear tire on a Razor 350 will not run/turn when the motor/tire is at a dead stop but if I advance the tire or motor spindle (while the motor or rear tire is standing still) the motor/tire will actually turn/run when I twist the throttle(!?)
@@__WJK__ I am making a guess, but I would think it might also be because of a weak battery. Because when you first engage the throttle, the motor draws more power. This might drop the voltage below the required amount needed to run the controller. But when you roll the tire a little, it helps it get started and does not draw as much power. I would monitor the voltage while engaging the throttle to see how much it drops. A second guess might be dead spots on the motor itself, but I think this is less likely.
J F - Thx! I’ll check the voltage drop.
Porque prende la moto pero no gira la llanta ni prende el motor
Omg thank u soooo much, I'm a 12 year old and I managed to use this tutorial to fix my dirt bike!!! Thx!!!
Cool Man! Glad you got it!
That’s crazy that means your 15 nos
Now*
Now your 15
U are 16 know
Thanks for the info brother!!! Picked one up for free off a friend and couldn't figure out even with 13V fully charged batteries. Makes sense the current is only pushing just over 1 amp rather then 7.5a the batteries are rated for!! Appreciate it!!
Thank you sir. This is what I was experiencing with my sons pocket rocket. Your a God sent. Now I know. Time for a new battery. God bless and thanks for making this video.
Good Deal!
Thanks !!! 🤗 My daughters Razor is doing the same thing !!! Time to get new improved batteries !!! 👍
More than welcome!
Thank you my son's was doing the same thing. I suspected the batteries as he turned the bike on sometime this winter or before and left it on so I figured he froze and ruined the batteries.
I checked everything, thank you so much. After I charged the batteries.. I bought two controlled but the same... something that simple...wow
how did you remove the ferrings/ Seat?
First. Thanks for the starting point. Same issue on my kids. Did what was suggested EXCEPT I did not have voltage drop! Dang. Checked connector to motor from electric controller NO VOLTAGE. Bad controller **it was clicking**, right. Easy. Amazon 2 weeks later. Installed. SAME problem!! Still no voltage out of NEW controller to motor??!?! Luckily I have second one. I played with components to find that the problem was the "ON/OFF SWITCH!!! Really?? Picked one up at auti parts store for 7 bucks.(make sure you install correctly or you will need fuses) Done. Ride like new again.
I didnt cover how to check a switch but should have. This video is almost 3 years old and maybe I should update with how to check all the components. Glad you were able to figure it out and get it running.
I have question
how do you charge the batteries? or switch them out? do you have a video for that?
Mines run but it don't run fast what's the problem brother
Joe Montez the motor
I don't know what to say about these lil razors. I just replaced my old batteries with 2 new batteries and it still clicking
Get it figured out?! I done samething. New batteries,charged them then installed them. Still just a click.
@@joseboyd4563 the controller has relays inside it. It could be the controller as failed. Check your voltages.
Hi. I have a bike with the same issue. Do you work on the bikes? I’m in Dayton Ohio and I would like to get this repaired for my son.
Just buy new batteries or try jumping them from other batteries
This exact thing was happening on my sons mx350 (powered on, single click when turning throttle, no motion). I pulled the fuse (which looked like it could have been slightly dislodged), checked it, and reinstalled it. At that point I turned the bike on and the throttle worked. I either got extremely lucky that the fuse just needed re-seated OR the fuse wasn’t the issue at all and instead there is a loose wire that I accidentally tampered with during dis-assembly and I’ll soon experience a non-mobile bike again. I’m leaning towards the latter as I wouldn’t have thought the power would have even turned on if the fuse was not seated right.
just replaced my batteries and my son enjoyed his dirt bike for a wk now it work ,the back is fine when turned on it runs but the back tires won't moved ,any ideas pls
So I just replaced the batteries because they weren't holding charge and everything was working great. However it seemed like the break was rubbing or sticking. So I loosened the brake, added a washer to the rear tire, and lubricated the chain and sprocket. Then everything was working great but I realized when I tried the brake that I had forgotten to tighten it back up. So once I did that the clicking began. After watching this video I checked the voltage with the load on it and like I suspected it still has 25vdc. I know the clicking and brake scenario are totally unrelated and coincidental. Do you know what else it could be causing the clicking? Could it be the motor?
Am experiencing the same problems, but I’m not getting the clicking. I replaced the throttle, still no clicking and problem persists. Any advisement on what it may be? Everything I read, says that the throttle needs to be clicking or else the throttle is bad. The throttle replacement, a simple plug-and-play, and I just put a new one on and still experiencing dead bike no clicking.
Did you ever find a solution?
No, I bought a new controller off Amazon for $25, haven’t installed but plan to this weekend. If that doesn’t work I may replace the motor for $36 from Amazon then it goes to recycling if still doesnt work. If I’m successful I’ll update here.
@@user-wd4cz4uo3x hey, thanks for the reply. Yes, let me know how it goes!
What if it doesn’t even click it turns on but it does nothing when moving the throttle?
Did you find a solution?
My zr350 turns on but when I hit the throttle i only hear 1 click n nothing happens.. is there any advice you can give, I don't have a voltage meter so I can't test the power outages
Thanks a lot for the video!!!
Mine starts well. Shows full charge. However it doesn’t go uphill - just picks speed heading down - any thoughts ?
My son's bike still runs but when he turns the throttle the idler pulley on the chains clicks up and down. Do you know what would be causing this?
Hi i bought two new batteries for my sons mx350 razor and they needed charged and so i plugged in my charger to charge them and the charger is reading green as if they were charged and there not. Any suggestions. Thanx
@jerrylroberts mine is doing the same, did you fix it?
Thanks but what if my light on the switch doesnt even turn on?
My nephew have one that rev's but the back wheel won't move unless you hold it up you now the problem to that?
Sounds like the batteries to me. There is not enough amperage left in the batteries to move any weight.
@@Fentertainment ooooh ok cool, yo get a new battery or charge it up?
*My chain spins but rear wheel doesn't spin? Had rear sprocket apart and couldn't figure it out, seems to not be engaging or something?*
thanks for the info!!!
Thank you I have same issue- just no torture to go anywhere
I have a different version of the mx 350 it clicks batteries are good just put in a new control module could it be the throttle?
Thank you so much man 👍
Thank you so much now I can fix my little brothers bike 😊
any idea on this issue? everything on the bike works well except the back wheel wont spin when the bike is sitting on the ground. When I raise the back wheel and rev it, it spins just fine with normal power. any suggestions or fixes would be appreciated
My daughters shuts off when going through grass. Any suggestions there?
Thx u so much I got a mx350 it’s clicks but don’t run I’m guessing I need to get new batteries
I remember when I first rode mine ❤❤❤❤ i hope it works I haven’t watched yet
I have similar hpr350. Got 1 screw near handlebars and 2 under seat by back wheel. Dang seat wont come off. Wont slide forward or back either.
Any suggestions for Hyper 350 with stuck throttle? When I turn the switch on, the bike is running wide-open without even touching the throttle.
Thanks this is a help.
What did your voltage drop do when you turned the throttle?
I have an answer for that...cause the throttle has to have juice..the same way your Starter in your car ..if it doesn't have enough juice the car wont start and same as the razor..the throttle takes a lot of juice to send to the battery.so if the batteries aren't good then the throttle wont crank the razor
were do i get parts i need some stuff
Mine doesn't click but when I plugged it up and waited a while it read that the battery was fully charged. I turned it on but nothing happened nor did the lights on the throttle turn on either. What could be the issue ?
The wire are disconnected in your motor,I had the same problem
mannyd39 k
The problem we are having is that when my son rides the safety shutoff engages. Even when he is in control and upright... Any thoughts
I’m trying to fix my little brother’s rsf350 it turns on but no click when turning the throttle. And I left it charging all night and the charger was green the whole time. Any help would be amazing!
You said that you checked the motor with 12 V? Does the system change from 24 to 12 v, or will that motor rum on different voltages? Thanks, great vi!
The motor will turn over on 12v to test. The controller needs a certain amount of voltage in order to operate. But bypassing the controller to test the motor on 12v is fine, it should turn over on 12volts.
@@Fentertainment i got you, thanks!
I have same issue but a use my makita batteries. I have 20 batteries and all click. What then?
Will it be good to replace the old battery with a cars
Mine has grease in the throttle doesn’t click but switch turns on motor works battery is pumping great power so
It’s a mx125 so if there’s no clicking it’s a go throw on the throttle?
My neighbors daughter payed her bike down while riding it and then after the wreck it started clicking and he replaced the batteries and still clicks. About to replace the controller and throttle to see if that will work. If we replace the controller and that doesn’t fix it, what do you recommend?
What if it clicks after installing new batteries? I have a pocket mod kids scooter
You just earned a subscriber my dude
You had mention individually charging the batteries? How? With what?
You could do it with a 12v charger to get the batteries up enough to put it on the regular charger. However you would need to remove the batteries to charge the individually.
I just replaced the batteries on one that was gifted to me and it's still doing nothing. What should I test or replace next, ya think? Controller or motor shot maybe?
Did you ever find an answer? Mine is doing the same
What if it clicks and also moves just a little .?? Charged it for awhile .
I checked battery voltage which was 24.2 volts. Turned switch on and it was still 24.2V. Had clicking sound but motor didn't run. Any ideas what may be the problem? How do I check the motor to see if it's good? Thanks.
What kind of battery do I need to buy to replace
what if I just get a new battery will that fix it?
My fuse is good, the switch light turns on but their is no clicking when I throttle up
My boys got one where the throttle won’t work all the time. When it works, it works but when it doesn’t, there’s not even a click. I’m thinking a short or a bad relay. Going to tear it down this weekend to troubleshoot. Any tips?
Its been 7 years since I made this video and I cant remember exactly. Is the throttle like a throttle or is it basically a on off momentary switch? If its just a momentary switch you could disconnect the connector and test it with a dmm set on continuity. Give it a bunch of pull backs and if the audible beep keeps going then you might be able to rule out the throttle switch. If it cuts out then it could be the throttle switch. If that makes sense.
I thought you were about to solve my problem! 😪.. so I’m having same exact issue… BUT .. batteries are brand new .. both charged 100% and both putting out over 13amps each .. according my battery meter … so why could be my issue? Bad controller? I haven’t tested the motor like you said you did .. I don’t know how
What is a supply hornus?
My son's razor doesn't click but the battery won't charge. I replaced the batteries and bought a new charging cord but it still won't work... any thoughts on this?
Also, my batteries are good, 27.2V when turned on. Bike won’t go, no clicking and throttle is fine. Any ideas?
Do you know anywhere I could get a new seat
Where can i find a motor?
So my son's electric dirt bike says its has full battery but when he rides it it goes slow. What do you think it is. ( my 5 yr old is riding it and 10 yr old)
The only true way of knowing the battery is fully charged is to test the batteries in the bike while the bike is on. However to me it sounds like the batteries are starting to go dead.
So I charged the battery and it says green. I hold back up and it runs fast but when my 5 yr old tries to ride it it goes very slow. So u think its the battery??
Pr200 battery hookup
I replace my sons batteries in his hyper electric dirt bike and it’s still not coming on. The charger is a little lose feeling but it charged it before.
I just changed the batteries for my son mx350 razor bike and it still would not go
You have to test all parts to make sure the batteries are the culprit.
having the same issue.. changed the batteries.. and get nothing what could it be?
HELP! I had the same problem. I bought a new motor thinking it was that. Then came accross this and replaced the 2 batteries . Then it still didn’t run. I replaced the esc to. EVERYTGING REPLACED NOTHING WORKS STILL MAKES CLICKING NOISE
Same here :(
Same here
Turns out my MX350 charging plug fits in the bike 3 different ways. Only 1 of the ways turns the charger RED. Once I figured out which way actually charges it, I marked it with a silver sharpie. Silver side up. Batteries don’t charge the other two ways. GLTA
thanks! mine was a blown fuse
How do you charge it
What if there no or clicker. I don't even think the power light comes on
Should replaceable the battery? If so whe,re would I get on
what does it mean if there is no clicking
My kids bike charges & we use it for few min & while he's riding it'll click & stop going. Then he presses that red reset button & it works again. What is that? A safety thing? WTH
My mx 350 clicks, but doesn’t run when the throttled is turned, with the charger on, but when I disconnect the charger, it doesn’t click when I turn the trottle.
Can I do this on a mx650
My son has had his for 2 weeks and it's doing this. I'm going to check the fuse but that's lame
Thanks so much
Do you think it is a bad idea to replace the old batteries with a car battery
These batteries are 12v each to make 24v plus these are sla so they will not spill like a regular battery.
It’s not a bad idea. Just make sure it’s AGM or another type of battery that won’t leak or spill. Remember- our kids are on it. Battery acid is not fun.
Mine won't charge or turn on what do I do
Thanks so much!!!!!!!!!!!!!!!!
When I turn my bike on it goes very slow what’s the problem ?
What happens if nothings haopens5
Can you do this for the mx650
I'm pretty sure you can. I believe all of the razor products are like this. My neighbor had a crazy cart that did the same thing.
I charged the battery 8 hours but my kid can rider 5 minutes only moving very slow I bought 2 new batteries same problem
Where are you located
Thanks dude
I Have new batteries and it still doesn’t work still clicks
Have you done a full test of the battery voltage before turning the bike on, Also after its on and while pulling the throttle. I would check all 3 of those and check the fuse between the batteries. You could have a bad on/off switch or throttle switch or controller. There is not much to these and a few simple tests would clearly show whats wrong with one.
I have one that just don't charge up with new battery
I need help fixing it for my son
Nice video!
Mine doesn’t run
Just changed the batteries and it is clicking, no movement otherwise
What if my batteries are new?
Hell yeah bro . Thank you sir
That's what my son's was doing now it's not even charging. Help?
My sons doesn’t click :( it doesn’t start even after switching to on and charging
That might be the fuse
what do you do if the controller is burnt
replace controller.
Fentertainment I did and it still won't run
My son has 3 of these and all 3 of his is doing the same thing and i cant even find batteries anywhere to replace them
I placed links in the description on where to find the batteries for cheap.
@@Fentertainment looks like they’re no longer avail on Amazon :(
Maybe it's time for the gas conversion
Mine was clicking and it was my throttle
