Not the two-wheels bad type of bikes with motors, but road bikes or mountain-bikes. No fixies though because outside of a track, fixies are damn stupid and dangerous. I know that there are a few bike enthusiasts here on oppo and there are certainly many interesting stories to tell. Plus bikes are gorgeous! Just call the blog Velociropnik or Velotonic or something.
