Tip 50: Ride after your lights fail

Darkness is a primal fear of any animal who a) does not sit at the top of the food chain like a hungry Californian sits at the business end of a sushi train; b) is not nocturnal, eyeless, a mole or deep-sea creature.
When the double-As in your LEDs fail, you will be forced to confront that fear.
Ride on? Risking bunyip attack, accidental cross-country sections and the insouciant violence of those big, blind, mole-like creatures, the cars?
Or abandon all hope, dismount, and transform into a humble pedestrian?

BONUS TIP: There are those who do not fear the dark, do not shrink or cower, but use it for their own nefarious purposes - bike ninjas!

Tip 38: Make a show of obeying the law

You're gonna stop at a light? Own it. 

Acceptable flourishes include the super-slow stop, the look-around, the impeccable posture, and the excessively careful acceleration. Don't waste this chance to show the world cyclists are citizens, upright and true.

BONUS TIP: *Tsk*ing at anyone else you see bombing that intersection is acceptable, but yelling has greater effect.  

Tip 12: Mount your bell and lights on the bottom of your handlebars

Global overpopulation is the inevitable endgame of this species, Homo Sapiens Sapiens.  A species so wise it invented redundancy.  Real estate grows scarcer, and it seems ever less likely the innovation-bots at a thousand Googles could save us from the impending Malthusian crush. 
You can help.  There's real estate out there just waiting to be claimed.  Take your bell, your light and your trip computer, and flip 'em.
Magic.  All that space you never knew you had, right there on the most crowded part of your bike.  Sprawl all over that newly exposed bar tape like a new suburb consuming subdivided farmland. Luxuriate a liitle.
You can even try out new hand positions.  Narrow accentuates the cleavage, while the off-symmetrical tweaks those neck muscles ruined playing too much angry birds. 

BONUS TIP: Plant your hands extra wide and feel the rushing air dry your armpits before you arrive in the office.
