I took my Kong Fu out on the Rad toy ride but the bottom bracket kept seizing up, it looks like it may have a bit missing? it looks like the main part on the left side screws on then its got a big nut on it but wondering if it should have two, one to lock it in place?
Will try and get a picture up later

Is it a one piece crank?
If so it sounds like the locking nut is missing :daumenhoch:
-
Not a 1 piece crank
-
doesn't look right that ,can you pull the crank arm off n get some pics , chains on backwards too :daumenhoch:
-
I will see if I can get the arm off tomorrow, the part behind the arm seems to have a thread and tightens when its ridden, how could I change chain round on half link? should there be one pin that's loose?
-
chain will split like a normal chain with a link splitter , check the side plates on the links after though to make sure they're not deformed or cracked round the hole,this where half links will fail :nuts: if you haven't got any spare links leave it as is should be ok , tis suposed to be run the other way round though
-
dump the half link chain. its been found out they stretch like mad. en vogue use traditional chains again now.
-
Bring it round Paul I will repair that for you.

Thanks Darren :daumenhoch:
shall I drop it off at the weekend?
