Front and rear bike lights must be connected to a 6V/3W generator, ie a dynamo

Hub dynamos are indeed more expensive (around 50€ as a starting price) but since bikes are the primary means of transportation for many people, I think they usually see this as an acceptable price for the convenience it brings (I know I do).

Also, quite a few bikes here are leased (for around 20€/month, including all maintenance) and those always have a hub dynamo I think.

Here's a hint: Germany is extremely car-centric and makes regulations that cater to drivers, not road safety.

Germany does rather well. Though the paper is 6 years old (and based on numbers even older) and the number of bike accidents in Germany have gone up since then.

Maybe there are some super expensive ones, but I don't think we can entirely blame cyclists. The design of affordable lights is just not very good.

This has been a feature of bike lights since at least the 50ies.

My 1975 vintage Peugeot bike already has a front light with a lens that directs the beam downwards, can be adjusted to point even further downwards with a screw, and even has a small shield on top of the lens to stop the beam from travelling upwards.

It works perfectly with the original dynamo and a cheap LED light bulb from Amazon.

What the hell, are your lights welded/glued in place to the bike frame or what?

Most bike lights are screwed in, and with those screws you can adjust the angle of the light both up/down and left/right like this: https://m.media-amazon.com/images/I/71AKoH1V25L._AC_SL1500_....

Speaking for my German bubble, there are roughly two types of bike riders: those who invest 1k+ on their gear and those that buy a flea market bike for 100€ and then fit the cheapest light they can find (that is, the ones I mention). Most students I know fall in the second category, making those lights quite popular.

It can't be that what he meant, since if you can adjust the vertical angle, you can stop blinding people.

>Most students I know fall in the second category, making those lights quite popular.

I know. I nearly ran over one who had no good lights, dark hoodie with no reflective gear, when I was reversing on a dark street, at night. Nearly shat myself after the close call.

I know students are poor, but God damn man, your life is worth more than a couple of Euros you're saving by running a crappy light who's battery died 2 years ago. Skip on a pizza/few beers in town one time and get a proper light.

You don't need to spend thousands of euros on gear to have a safe and visible cycling experience.

People are just stupid and lazy about their own safety, that's all. You only realize it when you switch from a cyclist to a driver, how dangerous these cyclists with no good lights are at night.

> the cheapest light they can find (that is, the ones I mention

Dude, that light you shared is a luxury compared to what most students I see have. Most have these god awful things with low battery: https://www.alibaba.com/product-detail/Bicycle-Accessories-S...

You have misunderstood. Obviously I can angle the light, but it still has a circular beam pattern like a torch. Dipped car headlights are not like that. They have a sharp cut-off at the horizon so you can light the road brightly without blinding oncoming traffic. Very few bike lights have a beam pattern like that.

Definitely not on any modern light. They usually have a rectangular beam pattern.

It's not exactly cheap (and probably can be found cheaper elsewhere), but then it's superbright 2400 lumen with 2 sets of leds (headlights and meeting/dipped lights) and a powerbank. You can switch with the buttons. I own a slightly different version (2200 lumen, same casing) and it's great.

edit: cheaper here: https://www.aliexpress.com/item/1005006446894517.html

But that applies more to running red lights, or using bicycle lanes in the wrong direction.
