My bike fell over while it was on the mini workstand the other day, and it turns out that the saddle landed on the trike's power level switch thinger, creating a hole. It is of course a discontinued BG saddle, so I expect the replacement process to be painful and quite probably expensive. I already know one current model that doesn't really work (I've got that on the Brompton, as it's fine for short rides).
Also, the chain replacement that caused it to be on the workstand in the first place has now shown up a worn middle chainring, so I need a new one of those too.
