Right on the heels of the hubless BMX bike concept we found, here’s a similar set up in a road bike by designer Bradford Waugh.  The hubless wheels are driven by geared rollers, but check out the crankset!

More pics after the break…


  1. Man that geared roller is going to spinning like crazy if this bike is going to get any speed. Looks like there are a huge number of teeth on the inside of the rim.

  2. What a shame their computer was broken at the time, I would have loved to see the engineering calculations for the potential sideways load on the rollers. I won’t even go near the ludicrous crank arrangement.

    I am assuming that the uni student (or am I being too complimentary here) is actually studying arts or history; certainly not engineering.

What do you think?
