TROUBLESHOOTING
CHAIN IS LOOSE OR POPS OFF THE GEARS
The rear wheel might have become loose, allowing the wheel to slide forward and making the chain loose.
REAR FREEWHEEL SPROCKET IS MAKING NOISE
If the rear freewheel is starting to make noise when riding then you need to lube the freewheel. WD40 is okay but you should use a
bike lubricant for the freewheel. If you let this get worse the freewheel will eventually fail due to drying out and it could seize.
FRONT FORK FEELS LOOSE WHEN STOPPING
While this is rare it can be very strange when you come to a stop and the bike feels like there is some play in the front-end. This
means you need to tighten down the top fork nut right behind the handlebars. For good measure make sure all the parts are
secure and there is no loose hardware.
