Who would have thought this could become an actual problem in a cycling event like the Tour De France? I wonder how exactly people can put a motor in their bicycle when the frames are so lightweight and think. In the article they have said that it was reported at least 7 cyclists last year were using bikes with some sort of motor component in them. Check out the article. Is this really a thing?
