I actually have that CatEye, Veloria (without the U, I see), because you recommended it. It is great for actual light, I agree. The Viva doesn't need to see. It just needs to be seen, and look awesome. This is truly just for looks .

My shop carries a different Spanninga in stock, so I'll probably have them put it on. It's a bit bigger than the Pixeo, but same basic idea. On this big bike with its giant fenders, the larger light is probably better anyway. That light will actually be for safety. The headlamp... not so much.

I'm going to order the Soma and put it on just for show, but if you have one for sale that will work, I'd love to buy it from you instead. You can PM or email me. The Viva is already very slow, frankly, so adding any rolling resistance isn't appealing. I'm learning its virtues, and its limitations. My friend suggested I ride a bike in a local 25 mile ride happening this weekend. "I can't," I said, "my Raleigh's brakes aren't working." "What about the other bike," she asked. I pictured myself riding 25 miles on the Viva and shook my head. It's just not that kind of bike. It's a big, heavy city bike that's a blast for 15 miles, but then I'm done. It's not great for hills. I certainly wouldn't commute on it, or ride it in a way that would really require dynamo lighting.

Now, my new Raleigh project, assuming I ever find a suitable frame... there, I'm going dyno hub, all the way!
