Steve got a new bike yesterday and just had to try it out today, despite the weather conditions. I don't blame him though.
My back tire didn't want to go where my front tire was going and I dunked my bike deep into the mud. You can't really tell from the picture and I didnt' want to step back in the puddle to prove the depth, but it was DEEP! I burried my handle bar right over the kill switch in thick, sticky mud. It still worked though. However, I don't need it to kill my bike. I do a good job of that without even trying.
Signs of a fun ride! (In case you don't ride and you're wondering; NO, they are NOT water proof!)
