getting a regular bike after my battery fails?

A dynamo in the front wheel solves that problem.

sometimes you can find a wheel with included dynamo( had one)

its not a headlight that I need as I dotn ride at night so much its the blinkies and you got to turn them on and off and remember to charge them. I could run usb cables to them all the make it all easy to charge. I already have two wheelsets dont want to buy another wheel. plus I dont really want the drag.

SRAM is now selling Quarq powermeters in the left crankarm for US$200. Variants are available depending on the bottom bracket. My brother is buying a SRAM Rival AXS E1 DUB Wide powermeter assembly, which fits his bottom bracket.

It's your choice, but the drag of the dynamo isn't noticeable and I found the convenience worth it for me. This tail light has a blinking mode and runs off a dynamo. I have been using B&M tail lights, but they don't blink.

The drag isn't noticeable, but I understand not wanting to buy another wheel. For me, the convenience was worth it. If you change your mind in the future, you can get a blinking tail light for a dynamo. I use B&M tail lights (toplight), but they don't blink. This one from Sinewave has a blinking mode. https://www.sinewavecycles.com/prod...ZgHgb_qrb8OvsDaWqO1UgwJBjgAyqzR3oL7G_rhj2VX45

I do like the convence though.

That's embarrassing. I rewrote the post and forgot to delete the first one. I didn't mean to repeat myself.

No quality pedal bike uses the front hub dynamo nowadays unless you're a bikepacker. LED bike lights have dominated the market.
Yes, I had a dynamo in my pedal bike a decade ago.

Out of curiosity, @RunForTheHills: Does the front hub dynamo support a thru-axle? What standard thru-axle, exactly?

I am not sure many, if any, bikes come with a dynamo, quality or not. Brompton offers a wheel from the factory with a dynamo, but it isn't standard. It is mostly bicycle commuters that use them. You usually have to add that yourself. You can either lace a hub into your existing rim if you are comfortable with wheel building, pay someone to build a wheel (~$50-$75 labor), or buy a prebuilt wheel with the hub in it. Yes, They have models that support through axle. I don't have any bikes with through axle, so I haven't used one. It looks like they support 12mm and 15mm.

I use LED lights with my dynamo. I think all head and tail lights are LED now, even the dynamo compatible lights.

Rebuilding your wheel just to have a dynamo and getting rid of your perfect front hub seems counterproductive. I do not deny SON dynamo hubs cover any scenario!

Most people would buy a prebuilt wheel with the hub already laced in it. Sometimes you want the rim to match your rear wheel and the prebuilts don't have your choice of rim. I have built a few wheels and it isn't that hard. And I can't say that I have gotten rid of the hubs I have replaced. I save them in a box, or if they are still on the wheel I hang it in my garage. It is about convenience and not having to charge batteries or ride in the dark if you forgot to charge them. You just hop on your bike and go. When you are using your bike to commute to work, you can't always choose the time of day you ride it. Riding in the dark is going to happen, especially in the winter.

Well, I would have never replaced a DT Swiss hub with a dynamo.
On a funnier note! In early 1990s, I commuted on an old-school steel road bike. As my late returns often happened at night, I installed two traditional dynamos: one on the front and the other at the rear wheel. Whatever it cost me in the pedalling terms, I was lit as brightly as a powerplant Until I bought an early battery powered rear-light One dynamo immediately went to a drawer!

Yeah, those friction driven dynamos were garbage. I had one like 40 years ago. But you don't even notice the drag of a dynamo hub when riding. The small amount of drag is caused by the magnets in the hub and not friction. The drag is lower when the lights aren't turned on. If you turn the bike upside down and spin the wheel, it won't spin forever like a normal hub. The German brand Schmidt makes the SON and they are considered the best quality dynamos. But there are also cheaper brands, including Shimano which is still good quality.
