I'm not a sponsored blog, but I'm a big believer in dynamo lighting, and the reason that most people don't use it the cost/ hassle of finding a pre-built wheel or having a custom wheel built up.
I just saw that Clever Cycles is offering an amazing deal on dynamo wheels- $99 for either 26" or 700c. (unfortunately it doesn't look like it's the 26" that fits old Raleigh bikes- stupid tire conventions)
Pair that with a $60 Lyt and you'll never need batteries again. IIRC my generator hub alone was more that $99, several years ago. While this one is probably not the same line, it's a nice deal, and I thought it was worth passing along.
We now return to our regularly scheduled riding!
