Car hit the bike, the front of the car depression and bicycle twist is not, why?
Now the car front and rear bumpers are plastic. On the one hand can make the car lighter to achieve energy conservation effect, on the one hand after the collision will collapse to absorb energy.
Car flat head rotten is safe design, people are in a soft landing.
Bike wheels can withstand a lot of force in the longitudinal force so a fat ride on the bike on the wheels will not be deformed and can cross it flat!
