    my sons razor mini chopper, had the same problem. I loosened the nuts on either side of the axle. Loosened an equal amount, now clutch engages. Adjusted tightness until just right. It goes really fast now. Luckily I tried this; I was one click away from ordering a wheel, axle & assembly.

Hello,

Thanks for using FixYa.

The pawls inside the free-hub (or freewheel) are gunked up (technical term here...). There is a ratchet mechanism that allows for coasting (when it disengages) and engages, when you apply force to the wheel. Try applying some lube to the inside might free this up.

I hope this helps. Thanks and good day.

It is the rear freewheel assembly causing the problem. if is fixable, but you have to be good with tools, the bicycle shop and the electric bike shop both said they couldn't fix it, but is is doable. 1. you need a special bmx tool that fits that back wheel, your local bike shop should have it in stock. 2. you need to remove the freewheel sprocket and disgard it along with the the bearings (make sure to unscrew the razor chain sprocket from the freewheel assembly and secure it for reuse). 3. either purchase a new freewheel sprocket for bmx wheel or remove one from a old bike (again you will a special tool for that). 4. screw the razor chair sprocket onto the new BMX sprocket (it goes on with the same 4 original screws, right over the sprockets. 5. Screw the freewheel back onto the rim now. tada its fixed.

Chain is turning but the rear wheel is not moving


What??? RLtoFixYa doesn't know what they are talking about. Your problem is a faulty/broke "one way roller clutch" which is threaded onto the rear wheel. I've already replaced 2 on my son's MX500.....

The chain on the MX500 dirt bike is slipping over the sproket on the back wheel. I've read the posts where the sproket turns but the wheel does not, that is not my issue. I'm thinking I just need to...


Is there a chain adjustment on this bike? It must be very loose to slip over the sprocket. See if there are two bolts that act as jacks to move the rear wheel back away from the drive sprocket. Loosen the locking nuts on each bolt, and tighten both equally until there is only 1/2 inch of play in the middle of the chain, then repost.

My son just bought a 26" Huffy Jolt mountain bike. The rear sprockets spin freely when the pedals are cranked either forward or backward - - that is, there is no coupling to the rear wheel. What can I...


The plastic is to stop the chain from touching the spokes, it cannot cause this problem, either the chain is not on a sprocket correctly or the rear cluster(sprockets) is not working.
Some spray lube may help, but if it is new, take it back to the shop.

How do you get the tire of the rear rim of the razor mx500 electric dirt bike???


i would suggest taking the chain off of the sprocket(cog), then loosening the nuts. then using tire-levers from a bike shop to carefully leve-off the tire. this should work....i have experience with bicycles....i race them! good luck!!!

Chain & Sprocket turn, but Rear Wheel Not engaging/spinning


The problem is witht he flywheel on the rear wheel assembly. I had mine fixed by a professional last night (at a bike store). Razor uses a very cheap spring that is designed to fail and then to top that off did not use enough bearings as well (12 bearings short out of the factory). My son had also sprayed WD-40 all around the back axle (trying to make it faster). This is bad because, the bearings are packed in grease and WD-40 is a de-greaser. Never get WD-40 anywhere near your back axle!!! Anyway, the flywheel was way easier to remove than I thought. It is threaded onto the rim's axle shaft and just screws off. Once you get the flywheel, off you have to take it apart, fabricate a new spring (my son's new spring came from an old 10 speed's tensioning spring), reset the 3 pawls, repack the bearings, put the flywheel back together, and screw it back onto the wheel. I will post a YouTube video on this later. Hopefully this is enough info to get you started.
