Apr 10	comment	How can I determine whether rust has made my bike unsafe? I guessed as much on the catastrophic failure point, but it's good to get some confirmation.

Mar 7	comment	Folding bike vs mountain bike I commuted this way for several months. After the first couple of weeks, I could reliably get the bike unfolded and going in less time than it would've taken to reach the station's bike racks - let alone unlock the bike and check that it's no worse for having been left outside. In city riding conditions, I was rarely doing more than 20 or 25km/h anyway, so I'm sceptical that a full size bike would have offered much.
Mar 7	comment	Folding bike vs mountain bike +1, great answer. One possible thing to add as an advantage is that the low frame and wheels tend to make falling off a non-issue: you can safely slide yourself off the seat and not worry about hitting delicate bits on a top tube or wheel during an emergency stop. Came in handy a couple of times on icy roads!
Feb 27	comment	What subtle factors affect performance in unsubtle ways? Good question! Regarding the wind, drag is proportionate to the square of the difference between your speed and the wind. Tail winds don't help much because as you bike faster, that distance gets small very quickly. Also why doubling head wind speeds actually quadruples the apparent effects.

Oct 23	comment	How do you shift your weight when leaning on a turn? @BenediktBauer Fair point!
Oct 23	comment	How do you shift your weight when leaning on a turn? +1 for never break + turn. Really good answer!
Oct 23	comment	How do you shift your weight when leaning on a turn? @BenediktBauer As mikezs says above, it's the airbreaking that's going to change things, and at 75kmph, even a small increase in your drag profile is going to have a major effect!
Oct 4	comment	Is it safe to Cycle with an Umbrella? Thanks for your view on the safety, but I really must disagree on the point about getting wet. It most certainly does keep you dry. That's why people around here are doing it. My attempts have verified this as well.

Oct 1	comment	Is it safe to Cycle with an Umbrella? @Unsliced fair enough. My earlier comment was a hasty and surprised reaction. This is a real question. I really want to know the answer, and I believe it does have one. So, when I returned to discover it was downvoted (without explanation?) and people had left comments suggesting it was a nutty idea, or something only a clown would do, I was rather upset. The reason for wanting an umbrella is that, keeping an umbrella in one's pack 24/7 is easy and unencumbering. In contrast, keeping a raincoat and hat around just in case is not feasible.
Oct 1	comment	Is it safe to Cycle with an Umbrella? @GordonM Rereading your answer, I feel I should apologize. The comments below the question primed me to look at your response as being yet more unhelpful mockery. You have offered a useful opinion, and although I think some of your points are questionable, I am grateful for your efforts.
