I've bought myself a little city bike a few months ago and since we're now approaching winter months I will need to install some lights to ride in the later hours. I've been toying with the idea of installing a dynamo hub and matching lights.
As far as I understand installing the hub itself would require me to completely rebuild the wheel, which I do not feel comfortable doing. I've noticed that some online stores are selling entirely prebuilt replacement wheels (e.g. here), which would suit me much better.
However, I have no clue what kind of wheel / axle system I have and all my research left me at best unsure and at worst completely confused.
I took some photos of my front wheel. Would anyone here be able to help me identify my wheel size and axle type, such that I can buy the right parts?
I believe I have a ISO 622/700C wheel. At least the number 622 is printed on the tire. However, I also see 28 there and I read that ISO 622 should be 29 inches, not 28. So I'm not sure.
In terms of the axle it seems to be neither a through axle nor a quick release, but something in between? I haven't taken the wheel off yet to give it a closer look, but it appears like the axle itself is held on the fork by a nut on each side. But then the fork is open towards the bottom on both sides, too, like a quick release would be I believe (you should be able to make that out on photo 3 and 4). So I'm super confused here.
