A big bike ride coming up in the future, and the bike starts to play up right at the start of the ride. Were this in Scotland, I may have just sacked off the ride entirely, but I'd driven 3 hours to get here, and if I had to climb the Eeb in heavy unassisted mode, I was damn well getting my money's worth. Thankfully, there were spurts of assistance, and eventually it just started to work again (after I'd climbed over half way up the one side).
