When I'm not bicycling, I'm a Linux SysAdmin. I'm on the board of my local bicycle advocacy group.

Bikes are my primary transportation. A 2009 Surly Long Haul Trucker, set up as a commuter and a 2012 Trek Ion CX. I also take the bus, but do not own a car.

comment Why are brake lights not common?
FYI, the magnic light has a bit of a "brake light" functionality, since it draws power from the rim moving past, it mounts on the brake, and it is pulled closer to the rim when you brake; so it flares brighter as you're braking. (but turns off once you're stopped)

What do you want to mount on this bike? Racks? Fenders?

comment How do I stop punctures for good?
The unfortunate reality is that there is no good way to stop all punctures for good. Even the very toughest tire/belt/tube combo is going to go flat if you hit a self-tapping metal screw, sharp nail, or most other strong sharp things longer than the protective layers of your tire.

comment How do I stop punctures for good?
A foam tube or other airless tire or tube will be flat-proof. It will also have a high risk of allowing the tire to pull off the rim when cornering, give a harsh ride (just one small spot absorbing bumps instead of the whole tire), have increased risk of rim damage, have worse traction, higher rolling resistance, higher weight, be amazingly difficult to install, and may actually be illegal where you live. They're an outdated technology, obsoleted over 100 years ago. More here: livestrong.com/article/222689-airless-bicycle-tires-review

comment What is the hazard turn signal?
I often see the 45-degree point used to signal a merge...

comment What is the hazard turn signal?
Yes, this matches my experience. Normal stop signal for "might need to suddenly stop", point with wiggly fingers for scattered hazard (glass, gravel), or just point for a more concentrated hazard (a branch, crack, etc).

comment Why don't road bikes have disc brakes?
It's probably time to update this answer. There's been an increase in less race-focused high-end road bikes ("endurance") and road-ish bikes (cyclocross, "gravel grinder", etc) with some of those getting disc brakes.
