I think if you have a cycling event and you allow assisted bikes you have to figure out where to draw the line. There are e-bikes that can go 40 mph, should they be allowed? How about small motorcycles? Electric motorcycles?
I'm all for charity rides getting participation and money and all but I wonder if allowing motors is a good idea. I know, there are idiots on regular bikes but the motor gives squids the power to attain speeds they might not be capable of otherwise.
