Give up the number 2 and 3 shavers.
Bald is beautiful!
Captain Jean Luc Picard fought the whole Romulan Star Empire with no hair! Then he fought off all the bad guy mutants with his left over time!
Kojak put murders in jail without a single hair on his head!
Mr Clean...heck that guy will clean your whole home!
The Rock wouldn't look nearly as menacing with a full head of hair. Look here...he looks rediculous.

I did the 'high and tight' haircut when I was in the Marines. Eventually there was only enough left for the high...but no the tight...so eventually you have to just accept it, shave it, and own it!
Power to the baldies!!! Hair is for the weak!!!
As for biking bald...I do recommend a helmet liner. Otherwise you get lines in your head where your helmet sits...and you can also get weird sunburns in the exact pattern of the openings in the top of your helmet. That is not a good look on anyone.
