Creacking and cracking noises

Hi, all,

I ride a 2024 Ridley Fenix Slic with Sram Rival AXS.

For the past few weeks, it has been making lots of creaking and cracking noises which seem to come from the bottom bracket (not fully sure tho).

Yesterday the bike became unrideable as the cranks just stopped spinning even when forcefully pedaling. It felt as if they were stuck. I stopped and pedaled a bit with my hands and after a while the problem went away.

The thing is, I was at the bike shop a few days back and they told me my rear hub is dead but i could still ride. They serviced the BB.

I had ridden the bike for 2k kilometers and mostly in bad weather due to Winter. I havent cleaned the inside of the bike.

What could be the problem? does it just need cleaning? I am attaching a few videos so you can see and hear what I mean. Any info would be really appreciated!

Thank you 😃
