  1. Looks more like a watch movement than a bike…….

  2. Looks as safe as grandma's old washing machine. The one that squeezed the clothes between the rollers.

  3. Looks AWESOME! How many horse power, 7?

  4. Why have 2 big cylinders when you can have 7 little ones? Also, with the engine sideways to the air stream it looks like cooling is a problem.

    1. Bet cooling isn't a problem with this one, because all the cylinders are in the airstream:

  5. I gotta say, the idea of a radial engine bike is a pretty cool one.

  6. Pretty nifty! Though looks more like a study in industrial art than a practical riding machine.

  7. The French copy nobody's engineering! ... and nobody copies the French.

  8. When this bike was first made they were trying to apply the radial philosophy from aviation engines to other platforms, so it was ab interesting experiment. I'd say they should have gotten pretty good torque (the radial design) and fuel efficiency (small cylinders generally ensure somewhat better fuel combustion) but abysmal reliability (too many parts) and maintenance costs (crappy parts)...

  9. Radial engine or rotary engine?

  10. Gee Francois, we have an engine left over from that model plane....

  11. I like the pedal option when the engine dies. When I was very young - in the 1950's - there was a neighbor who had a bike that he pedaled up to speed and then the bike tried to keep that speed going. I really wanted one but mom and dad said no to my 6 year old self, sigh.
