Hmmm - interesting! The 0 at the beginning of the message is a return code - and a return code of 0 normally means success.
Do you have access to myphpadmin to go and look at the structure of the bikes table and tell us (or better still post a screen shot) what the table structure is, perhaps before and after you get this error.
Also, are you on the latest GitHub - if not can you update and retest.
Thx.

P.S. It could be something about having multiple lists pointing to a single table - which I think means multiple elements pointing to the id field. If some of them are not internalid elements, then I could see there being changes made to the column definition when you edit them.
