Bikoff briefcase bike image - Imagining the bicycles of tomorrow (images) - CNET News There are 12 photos of ideas of futuristic bicycles, interesting and weird ideas. The only ideas that I liked were photos 4 and 5. Photo 4 I like the design, or should I say looks, but immediately some problems came up from what I could tell. 1st problem was flat tire or tire replacement looked like it would be a real pain. The 2nd problem is the seat location to the pedals, you would have to pedal the bike with your legs more out in front of you instead of almost under you. Photo 5 is more practical, more like a bike we ride today with the seat in the same position as todays bikes, fast removal of wheels for repairs. My only problem is the integrated lighting system in the handlebars, which means an expensive repair or replacement should something fail; the other possible problem is the number of gears in the hub, if 9 or so, probably no big deal for most except those that ride mountain roads and tourers. Which ones do you like and why?
