Me and my buddy made a small ramp and we did like 10 or 15 jumps then we hear this loud bang noise or something come from rear wheel. Now the wheel wont spin but the chain sprocket for the wheel will. Plz help me fix this.

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.
SOURCE: how do i adjust the
The chain tensioner is on the right side of the bike a few inches or so in front of the tire on the rear swing arm all you do is adjust it up to tighten and down to loosen it.
