Yesterday - I slung my leg over the seat, and when my ass hit the pillow, I could tell something was wrong. Sure enough, the back tire was flat. Today, I got the back end off the ground, and sure enough, I found a screw stuck right smack in the middle....that extended service card got one more hit before expiration lol. The bad news is, that rear drive belt has seen its better days, and the warranty won't cover that. Win some, lose some I guess.
