comment Why are battery-powered lights so popular?
My experience is that with a good dynamo and lights, and with proper wiring (good wire, proper connectors [implying lights that have connectors] and careful fastening of the wire to the frame), a dynamo system can be quite reliable. My bike is constantly in the rain and parked and handled a lot, and I rarely have connection problems (maybe once a year). But of course this may depend on the specific situation. The wiring is certainly an added risk compared to battery-powered lights.

Why does a mountain bike need a through-axle? Can't you just use a hub dynamo with a solid (but robust) axle?

comment Why are battery-powered lights so popular?
That's the point - with a reliable commuter bike, you don't necessarily need spare tube and inflator (at least I don't need them), so having to carry a spare battery pack is an extra nuisance. And I have used dynamos (both hub and side wheel) for years and never needed to clean/grease them.

Also, you can get a dynamo for way less than $250. A decent side wheel dynamo is around $20-$30, a dynamos are around $50-$250, plus new wheel (prices from Germany, in US $).

Good point. However, this ignores the fact that dynamo lighting may require less maintenance, because there's no need to change batteries, ever, thus no risk of a battery going flat at an inconvenient moment. Whether or not this is a problem depends on how and when the bike is used.

comment Hill riding: What gears are usually the most comfortable?
Also, higher load means more strain on the joints (particularly the knees), which can cause permanent damage.

comment Broken glass on the bicycle path, what to do?
@DavidMulder: True, but usually (at least in Germany) there are exceptions if the cycle path is "unusable" (due to ice, snow, debris, construction...). "full of glass" might count as an excuse (I'm not a lawyer, though).

comment My lock was rusty and key snapped while trying to unlock bike so now its permanently locked
You'll probably need to open the lock by force. Please edit your question to indicate the type (ideally the model) of the lock.

comment Anti-puncture options
Also, you should always pack a spare inner tube. That way, you can quickly fix the flat by changing the tube. Then you can later patch the puncture at your leisure in dry conditions and use the repaired tube as the new spare.

comment Periodic Maintenance Task for Bike Commuters
@Batman: Yes, and so is a complete tear down. I've used bikes for years without ever tearing them down completely. Also, on modern bikes most bearings are not serviceable anyway (unlike old bearings, where this made sense).

comment What accessories do I have to add to my bike so that I may commute during rainy weather?
IMHO a seat cover only makes sense if the seat can absorb water (leather, cloth). For seats with a plastic surface, you can just wipe off the water, which is much easier than always putting on and taking off a cover. For leather, however, a cover is essential, as otherwise the leather will suffer.

comment What to use to clean your chain (and cogs)?
@Benzo: I did not want to imply you should not clean the chain at all - I just wrote that you should only wipe it off from the outside, and not bathe it in solvent. So there's no contradiction :-).

comment Does gear ratio affect Power?
As to max vs. efficient: Most efficient would be like a car - the speed/cadence which lets you travel the longest distance before you run out of fuel. Like a car, that is not necessarily the speed/cadence which gives you maximum power. And higher cadence generally means lower gears.

comment Does gear ratio affect Power?
As to the power thing: What I meant to say was that it depends on where you measure the power. If you measure power at the wheel, it will always be the same for the same speed and terrain. However, the power that the human has to exert may be different.
