Razor MX650 clutch on rea axle won't drive

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.
