First, some old business - Solid tires with a strip of rubber on the outside. The Germans are way ahead of me. http://www.myriadonline.co.uk/likeabike.php ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ MAIN TOPIC - BICYCLING ON THE MOON They brought a go cart up there in the sixties. I think they missed an opportunity. They could have brought up a specially made bicycle. They already had the engine - an astronaut. They had the fuel - space food. (back then eating food out of plastic pouches was only done by astronauts in space.) All they needed was a properly built moon bicyle or trike. What would it look like? How fast would it go? What special features might it have had? Why didn't they do it? Since there was no atomosphere and less gravity, I think it would have gone faster. Wouldn't there be less friction with the ground in low gravity? Maybe the bike could have been geared to go further with each stroke. Jumps would have been awesome! NASA might have invented the first mountain bike ten or fifteen years earlier had they sent a bike to the moon. What would an astronaut on the moon wear cycling on the moon? I don't remember how hot or cold it was. I think temperatures varied greatly. This would have determined what they would wear and of course they'd have to bring air tanks which are heavy. Astronauts could pedal their bikes 74 miles per hour on the moon.

The surface is reasonably smooth, but quite soft, so wide low pressure tyres would be needed but suspension can be dispensed with. The Space suit is restrictive on joint articulation, so an upright position is also demanded. Finally, to be UCI legal, the bike would have to have a mass approaching 50kg, because UCI commissaires have no understanding of science and would therefore want it to weigh 6.8kg on spring balances calibrated on earth. Fortunately, such a machine already exists at well below NASA budget prices; The Surley Pugsley The difficulty with predicting achievable speed is that most of the resistance comes from shifting moon dust - we've all felt the sudden deceleration of hitting a patch of deep, soft sand. Guessing that rolling resistance is increased by a factor of 10, I think 50km/h at 300W might be feasible. Kinky Cowboy* *Batteries not included May contain traces of nuts Your milage may vary

Another billion $'s ought to be enough to build a collapsible bike to go along for the ride.
