comment What's a safer alternative to a flag for marking special bikes?
@Mσᶎ - Bob Stuart's tailfin is on a trike/velomobile, I think it could be tricky to adapt to a standard bike without a lot of work. Daniel - it's about 600 riders on the ride, so vests not visible from far enough away in crown is a real problem, but I also think smaller flags would still work. But it does ideally want to be something distinct from a standard safety flag.

Yes. "It depends on local conditions" is the right answer. "It is certainly rude" is, in some conditions, just wrong.

comment DIY solution for carrying kids on a long-john: ideas?
Modern car child seats use en.wikipedia.org/wiki/Isofix. I think I'd second Chris' suggestion of a child bike seat. But just adding a neck support (and harness) to the box with ply seat as shown on the Bakfiets wouldn't be hard, would it?

comment Should the laws be amended to allow cyclists to run red lights?
movingtargetzine.com/article/… was a particularly bad example, the driver admitted looking for paperwork in his cab while turning.

Actually this is one place that cyclists passing a red light can save lives. Cyclist stops at a red light. Truck comes up behind/beside cyclist, puts cyclist in blind spot, and driver forgets cyclist is there. Lights turn green, both vehicles set off, driver swings left crushing cyclist against railings. If the cyclist sets off before the light changes, they can get clear.

Some places do allow cyclists past stop lights in some cases without problems - bicycledutch.wordpress.com/2012/10/25/… theurbancountry.com/2012/11/bicycles-and-red-lights.html

That's a fairly common problem, but passing a light that isn't working properly after stopping is bit different from "run red lights" etatrust.org.uk/2013/09/…

lcc.org.uk/articles/… 'I remember saying to Dutch engineers: “Well cyclists don’t stop at the lights.” And they said: “Well what’s the matter with your design?”'

If it doesn't make a difference, then they haven't gained anything. And if, as is common in congested stop-start traffic, the average speed of motor traffic is lower than that of cyclists, no they likely wouldn't have to do it anyway.

comment Figures on accidents involving cyclists where motorists are using cell/mobile phones
rospa.com/roadsafety/info/mobile_phone_report.pdf has some references, as does en.wikipedia.org/wiki/…, but nothing that would let you pick out specifically cyclists. And I doubt you'll find the UK ban significantly reducing accidents, because so many drivers ignore the law.

comment Is it rude to take the lane, then filter when encountering congestion?
Yes. A cyclist can see exactly how close his hands are to the side of a car, and can be sure a stationary car won't wobble, and that the breeze of their passing won't disturb the car. A driver passing a cyclist at a higher speed, with much less awareness of how close the outside of their vehicle is to the cyclist, and generally without realizing how a two-wheel vehicle behaves, is much less safe.

If you don't take the lane, and get passed by cars only to be held up by them when it gets congested a few hundred yards further, then the car drivers have gained absolutely nothing, have possibly endangered you by passing too close, and are now holding you up unnecessarily. Avoiding that situation certainly isn't rude, and it is certainly rude of drivers to insist that you put up with that situation.

comment Do Mandatory Bike Lights at Point of Sale Save Lives?
German law requires dynamo lighting on most bikes. There's an exemption for lightweight road bikes, which apparently might be relaxed more generally - sueddeutsche.de/auto/…

comment How do you install a hub dynamo?
It is, in theory, possible to destroy a rim by massively overtightening the spokes when building the wheel. But it's unlikely. What you can do on some dynamo hubs is break the internal wiring by turning something that looks like it might adjust the bearings - make sure you read the manual for your hub. It probably has sealed bearings you can't adjust anyway.

comment How do you install a hub dynamo?
I've built hub dynamo wheels. Unless it's a small wheeled bike like a folder, the shorter spokes aren't going to make a significant difference. It's still a symmetrical front wheel, which is easier than a back. Well, unless it's a Sturmey Archer rear wheel combined dynohub and hub gear.

comment How do you install a hub dynamo?
The advantage of a spoke cutting machine (which puts the new (rolled) thread on a cut end) is that a store can create spokes of exactly the length needed for any wheel that a customer brings into the workshop, without having to wait to order new ones in, while only needing to stock a few sizes. But even a cheap one is indeed a lot more than a set of spokes - billys.co.uk/english/group.php?prod=2CY07836
