Noise when cycling

[aravind123]

I’m not sure how to explain my issue but I’ll give it a go.. So for some reason when I am outside pedalling and if I put quite a bit of force whilst pedalling there comes a I think somewhat squeaky noise which I believe to be coming from the back wheel. However when I put it on a bicycle stand and I start pedalling there is zero noise, it only happens when I am outside pedalling. Does anyone know why this is and how to solve it. Thanks a lot.

Could be the bottom bracket or even the wheel or pedal for that matter that only reacts under load.

Bottom bracket, loose pedal or freewheel/hub would be my guess. Bike and BB type? Freehub or freewheel?

Has the back wheel any rubber seals on the hub. These can squeak when /if they get a bit dry. Smear / squirt some oil, even a quick splash of WD on the seals, see if that solves it.

What age is the back wheel?

Check your cycling shoes are not touching the crank arms as you pedal
