clean your garage and you will have it. or try bike shops.

If your bicycle doesn't have mechanical gears, the issue might be related to the freewheel or cassette, depending on your bike's specific setup.

Standard WD40 is just a 'quick fix' as it isn't an actual oil unless the can is clearly labelled as "Bike All Condition Lubricant". It'll be best to buy a proper light oil like 3in1, 151 Super oil or an actual chain lube. This 'clickey' noise. Is it random and happening every so often or is it a constant, regular click that changes with the speed your pedalling at? Check for slack in the chain. as you wiggle the chain up and down there should only be about a centimetre of movement in the chain. If it's too slack or too tight it can make strange noises. Check the axle bolts and nuts to make sure they're not loose. Check the wheel is mounted straight. If it's turned left or right the chain will 'skip' as it's slightly missing the cog teeth on the wheel. Use the frame at the rear end of the wheel as reference and measure how far the side of the wheel is from the frame on both sides. It should be about the same both sides.
