comment Looking for an old fashioned bicycle with coaster brakes & hand brakes for a woman
@DanielRHicks: Many internal-gear hubs are offered with coaster brakes. For example, the Shimano C6000 Nexus (8x) and SRAM i3 (3x) are available with coaster brakes. In Germany, internal-gear hubs with coaster brakes used to be so common that one German webshop displays a note with the gear hubs they sell: "Warning, does not have a coaster brake".

comment Looking for an old fashioned bicycle with coaster brakes & hand brakes for a woman
@DanielRHicks: About bikes with coaster brakes not having front handbrakes: This totally depends on the area. For example, in the Netherlands it is quite common, at least on cheap bicycles, for the coaster brake to be the only brake. In Germany, two independent brakes are required by law (for bikes used on public streets), so bikes have a coaster brake + a front hand brake (of varying quality).

comment What are the risks of fenders?
@Rider_X: No, I don't have any evidence, just dim memories of articles I read. My understanding was that metal fenders are more sturdy and thus less likely to fold up. Of course, if they do fold up, they will jam even more effectively. Anyway, the point is mostly moot now, as most modern "full" fenders are plastic fenders with safety clips, as I described.

This is true, but is unlikely to be an accident risk. Ice/snow will usually build up slowly and gradually slow you down, and not cause a sudden, complete lock-up of the wheel.

comment Group of Bikes: Is 3x1 an option?
@freiheit: Nitpick: Actually, they go up to 14 ( Rohloff Speedhub ) . Of course, that hub is way out of price range for this question.

comment Why are battery-powered lights so popular?
Well, not really. 1) is true, but with a proper dynamo 15km/h is enough for nearly full power (German standard TA 24 mandates 5.7V-7.5V from 15 to 30km/h). In practice, brightness stays constant once you reach 12-15 km/h with halogen, or 8-10 km/h with LED. 2) used to be true, but almost all modern lights for use with a dynamo feature a "standlight", where a capacitor is charged during use, which can then supply power for some minutes even at slightly reduced brightness.

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).
