Professional software developer for multithreaded, low-latency, time critical code. Formerly engaged in embedded software for medical engineering.

I'm a bicycle nut who owns five bicycles, from an Enduro MTB to my relatively new Velomobiel Quest. Yes, some of my bikes are more expensive than my car was. I do all maintenance myself and have even built three of the bikes from parts.

If there's time, I do some electronics, mainly high-power LED and microcontroller stuff.

There's a reason these things are called "rim-killers" in the german road biking community.

comment Are there sirens/horns that are like a car horn?
While this doesn't answer the question directly, the advice is very good.

Also, if the bike has all original parts and is in good condition, sell it to some retro nut and buy a brand new bike.

If you continue to use drop bars, use drop bar brake levers and possibly "cross brake levers" in addition. If you find a straight bar more comfortable, use one of those. Also, V-brake levers pull too much cable for road brakes. You'd have almost not articulation.

comment Are these bikes real from Aliexpress?
And even if it were real. A folding mountain bike? Really? Also, what kind of components do you expect if you spend less money on the whole bike than most people do for their bolt-on grips?

comment My bike after a new spray paint, gets scratched easily
@Kibbee I don't think that's true for most road bikes and I know quite a number of touring and mountain bikes that are painted instead of powdered.

comment Minimum mountain bike trekking/touring equipment
Re saddle cream: Good idea, but you should try that before such a ride to get used to the somewhat "full diapers" feeling it gives before getting evenly spread and warm.

Flares are virtually useless in most situations. They can't be seen well during the day and even at night many people don't know what to do if they spot a flare. Same goes for alpine acoustic signals. It's a nice-to-have, but a cell phone or small radio, tuned to the right frequencies, will do much, much better, especially if you can somehow get a GPS fix across for the helo.

If you sleep in huts every night, you might get away without a mat and with just a silk sleeping bag inlet ("Huettenschlafsack" in german).

Re tools: You should still carry more than one of those tools that easily break and cannot be simply repaired or worked around, e.g. tyre levers, pumps, ...

comment When to replace rear derailleurs
It could be that the spring will break at some point due to material fatigue, but that is also a relatively easy to replace part on most derailleurs. And the jockey wheels will go before that.

Maybe ask around whether a collegue or the resident IT-guy has the necessary tools?

comment Things to consider when choosing a recumbent
Below-the-seat steering is at a slight disadvantage with respect to aerodynamics as it will make your silhouette wider. There's a reason all very race-oriented bents have praying-mantis-style handlebars.

comment What is the best way to stop and restart at a stoplight?
Starting with the non-dominant foot from time to time is not a bad thing at all. Especially if you ride in the city a lot, you will get unevenly trained, which may result in back pain.

comment How tight should brakes and shifters be on the handlebars?
@Aaron That's what happens if you land front-wheel first after a jump and flip over, when the bike contacts the ground with the levers first. Or if you low-side out of a bend at high speeds.
