New: Take Part in the May Giveaway for a Change to Win the Thruster 27.5 Retrograde BMX Cruiser Bike


This has broken loose. What is missing?

This is a cheap and rusty old bike, but it's one my son has really enjoyed.  I can't figure out what broke off that would make the crank area loose.  If anyone could identify what broke or what part fell off or what the issue could be, I'd be most appreciative.  Thanks!

Guessing. But I think the bearings on the non-drive side (side without the chain) disintegrated.

If so you need at least a new set of bearings. Most likely would need to replace the whole bottom bracket (bearing and cup assembly.) This would not be expensive or very complicated. Don't really need any special tools. But there are some tricks and tips you need to know, especially as a couple parts on this have reversed threads. Google "replace one-piece bottom bracket" and you should find more info.

Agreed; you are probably going to need something like these:

and some grease, I use boat trailer wheel bearing grease, low cost, water resistant. lasts a LONG time.
