>>1545057They're common problems, but they need specific tools and some bike knowledge to fix.
>click from cranksetprobably a dying bottom bracket, you need a new one, plus the tool to extract/install it, plus the tool to extract/install the cranks, plus grease. Also there's no guarantee that this is the actual issue; a click coming from the crankset could be like 20 different things.
>click from rear wheel axle (hub)dry hub/pitted bearings. you need flat spanners to remove the cones, new cones, new bearings (and grease). If it's too bad, maybe new hubs (which would mean rebuilding the wheel)
>rear wheel bentyou need a spoke wrench, and more importantly, to know what the fuck you're doing.
The last two issues could also be solved by just buying a complete new rear wheel.
All of these issues fall into the "general maintenance" category, which any bike shop could provide for you. The problem is, thanks to corona, prices and demand have skyrocketed, so depending on where you live this could be rather pricy. See if you can find a shop willing to work on your bike for a decent price, otherwise just save up for a new, better one.
You could also just go for it and buy all the tools and parts you need, it'll be hard and somewhat pricy, but they're tools that you're gonna have to buy eventually anyway, and tools last forever.
It's your call.
