Personally, I think leg-assisted motor bikes will cause the downfall of Western society and should be strongly opposed on all fronts. They make you fat and lazy, or if you are already fat and lazy, allow you to do something you really shouldn't be doing. They promote lawlessness by encouraging scofflaws to use public infrastructure in a way that is prohibited (or at least wasn't the original plan). And they are just plain creepy. I mean, who can ride along at 25 mph, not breaking a sweat, pretending to be pedaling and smiling all at the same time? Not even Lance all doped up could do that. Folks, we (the real cyclists) need to stand up and fight this scourge on all levels.
