Not one, but both wheels today 
500 odd miles on the bike since getting it a few months back and today 7.5km into my 11km ride home I noticed the back end suddenly feeling very loose as I went round a tight corner, hopped off and sure enough the back tire was very low on pressure, oh well just a few km left to walk home, about a km and a half later the front was flat too, assuming I did both at the same time and simply a lack of weight on the front stopped it from going down as quickly as the rear, blooming annoying though.
I was made up by the fact that out of the four cyclists that passed me while walking two of them quite happily offered to help and fix it on the spot, bloody marvellous
New tubes and a repair kit ordered, will get it sorted by the weekend I hope. How much grief is it going to be getting the tube done on a real hub motor bike? I guess I'll need to disconnect the motor to remove the wheel fully?
Do you all carry spare kit with you when riding or just deal with the fallout when it happens? I guess at some point I'd just decided that wherever I am in my ride I'm at most 5.5km from either my place or my mothers where I leave it locked up in her garage when I go for a swim so it's no massive issue to walk however far is needed.
