If the gear shifts on your FITFIU FITNESS Bicycle aren't working correctly, it could be due to sticking, stretched, or damaged derailleur cables (lubricate, tighten, or replace them), front or rear derailleur not adjusted properly (adjust derailleurs), or indexed shifting not adjusted properly (adjust indexing).
What to do if the chain is slipping on my FITFIU FITNESS Vintage Bicycle?
If the chain on your FITFIU FITNESS Bicycle is slipping, it may be due to excessively worn or chipped chain ring or freewheel sprocket teeth (replace chain ring, sprockets, and chain), a worn or stretched chain (replace chain), or a stiff link in the chain (lubricate or replace link). If it is because of a non-compatible chain/chain ring/ freewheel, seek advice at a bicycle shop.

Constant clicking noises when pedaling your FITFIU FITNESS Bicycle could be caused by a stiff chain link (lubricate or adjust it), a loose pedal axle/bearings (adjust the bearings/axle nut), a loose bottom bracket axle/bearings (adjust the bottom bracket), a bent bottom bracket or pedal axle (replace the bottom bracket axle or pedals), or a loose crank set (tighten the crank bolts).
What to do if the chain keeps jumping off the freewheel sprocket or chain ring on my FITFIU FITNESS Bicycle?
If the chain on your FITFIU FITNESS Bicycle keeps jumping off, check if the chain ring is out of true (re-true or replace it), if the chain ring is loose (tighten the mounting bolts), if the chain ring teeth are bent or broken (repair or replace the chain ring/set), or if the rear or front derailleur side-to-side (adjust derailleur travel).
Why is there a grinding noise when pedalling my FITFIU FITNESS Vintage?
A grinding noise when pedaling your FITFIU FITNESS Bicycle can be due to pedal bearings being too tight (adjust them), bottom bracket bearings being too tight (adjust them), the chain fouling derailleurs (adjust the chain line), or derailleur jockey wheels being dirty or binding (clean and lubricate the jockey wheels).
