When was the last time you bought a bike? They have shock absorbers now.
I can see it now, "The federal govt. has announce a new program by BHO. We will now pay up to $100 to refit every bike with shock absorbers. This $200 million dollar program will create at least 12 new jobs."
Considering the amount of traction a bicycle tire has on gravel, I hope that they also have side air bags!
