Pedal gear makes snapping noise

If the wheels spin free then I would look at the bottom bracket. All of the force you use for pedaling relies on the bearings in the bottom bracket being good. Are the pedals hard to turn by hand? Do the pedals themselves spin freely? If the wheels turn, this really only leaves these two rotating points as possible suspects.

not knowing if this is a single speed or multispeed bike, this could be several different things and a proper analysis by a mechanic at your local bike shop is what is needed.
It could be that the chain is too tight, it could be the derailleurs are out of adjustment and the chain is skipping between gears or rubbing on the derailleurs. It could be a bottom bracket out of adjustment and the bearings are loose and making the noise. It could be a loose bottom bracket shell in an aluminum frame make creaking noises.

does it make the "clicking" noise when coasting, pedaling or both? If it is only when pedaling, check to make sure the cranks are not rubbing on a chain guard or hitting the frame, if not then the chain is probably too tight and it is the gear cog teeth meshing with the tight chain. Loosen the rear axle nuts and slide the rear wheel forward slightly, this should take care of it. If the noise happens while coasting then one of the wheels could be rubbing on the frame intermittently, or the hub bearings could be too tight (also making it difficult for small legs to pedal) and the bearings are crushed and flattening making the "clicking" noise as they are being ground up.

Hills are not meant to be climbed at a fast pace. The lower gears make it easier for you to convert your pedal movement to tire rotation so this is why you seem to be not going anywhere. Try a higher gear so that easier pedals make less tire movement allowing you to climb hills with ease. Practise on flat ground till you get used to the gearing then always remember to have the right gear selected before you encounter the hill or your climb will be just as tough.

Your gears work like this: The bigger the chain ring on the front where your pedals attach makes for faster speed and is accompanied by harder pedalling. The bigger the chain ring on the back where it is attached to the wheel makes for easier pedalling and less speed. Remember to never use the opposite rings. Eg. Do not use the largering on front with the large ring on back. You will over stress your chain and could break.

Try this, leave the front chain on the middle ring and only use the rear drailleur and get use to the range this set of rings has before you change what front ring you are using.

Happy biking and I hope this helps.

Raise the seat to a height where when your pedal is at the bittem of a stroke there is about a 20-25 degree bend in your leg. Also pedal with the pedal's axl on the ball of your foot. If you can change speeds, the smaller the cog in the FRONT the easier it is and the smaller the cog in the BACK the harder it is to pedal. If you still can't get it right, take it to your local bike shop for tips and adjustments. Don't be afraid to ask for help from a bike shop. Bike people love to help others with biking stuff.

Do you mean the rear derailleur?


It almost sounds like rear wheel isn't 'freewheeling' properly. The gears on the rear wheel should be able to remain motionless (with the pedals) when you coast. Does it do the same thing if you just walk the bike or does it make the pedals rotate as you go? If that is the case you could seriously damage the derailleur if it isn't resolved.

Catastrophic lack of lube in it hub or freewheel body will make it seem to be in a fixed relationship with the wheel. A bike shop would have the proper expertise and tools to lube it properly.

First have the linkage from the clutch pedal checked out then if no result have someone check out your clutch it may be worn out.

Be advised the left pedal is left-threaded. Get yourself a nice Park brand pedal wrench.

What fixing nut?

How to:

Before stripping the gearbox be sure it isnt just the gearshift pedal rotating slightly on its shaft. The splines on the shaft will ruin the pedal if its not tightened correctly.
Otherwise it could be the gear selector mechanism. The spring on the shift claw or detent arm may be broken.
Check it out by rotating the rear wheel whilst the bike is turned off & on its main stand, then select each gear by hand with the pedal.

Good Luck
Hope this helps.

Hi! No worries about the lingo!
What you are referring to is the free-wheel hub.  This is the rear hub which allows you to have load when you pedal forward, and then move freely when you pedal backwards.
I had a similar experience with a trike and what was needed was to pull the inside of the hub and replace a small spring that looked kind-a like a safety pin.  This is what makes the clicking noise when you pedal backwards or move the bike forward without pedaling.
Not all repair shops are willing to make this repair, and to be honest, I ended up having to go back several times to get the same part repaired, until I gave up and purchased a new hub. If you like to bike a lot and go far, this would be the best course of action.
Good luck!
