Re: electric motorcycles are coming to the USA
Thanks guys. That is really quite fascinating. Now why doesn't the governments of our respective countries consider these alternatives ??.................................Oh yeah, they can't make any real money promoting something good for taxpayers.

Re: electric motorcycles are coming to the USA
Well, MDI, made some claims in recent years that their compressed air car was capable of speeds of 68 mph for a distance of 80km but to this date they have not produced proof of those claims. The best anyone has been able to achieve in independent studies using MDI's specifications is a range of 7.22km per charge. The problem is that the energy density of compressed air even at 4500 psi is very low even in comparison to the most inefficient lead-acid batteries. Air power has been successfully used in service vehicles and platform trucks in plant operations where air supply points are readily available but still have not proven to be as effective as battery operated equipment. One major issue with compressed air is the tremendous amount of heat energy that is absorbed when the air expands. The air needs to be rewarmed with a heat exchanger to keep air pressure at an optimum level. The heat exchanger can serve as A/C in warm climates but would be ineffective in cold or even cool climates. Any moisture in the air will readily turn to ice and plug up airports and freeze up the motor. Since compressed air technology is cheap the vehicles would be inexpensive...with that being the case if it were viable for transportation we would already see them in every driveway IMO.

Re: electric motorcycles are coming to the USA
A few years ago Chrysler Corp. was making big waves about their wonderful Natural Gas powered minivans. That was looking good until one was taken on a road trip. With very few refueling stations and it's rather sad range per fill it was a major exercise to get anywhere. It was towed a lot. Gotta love the mag writers who test these things for us.
Quite a number of years ago a friend of mine had a NG powered company pick-up. Would have been great if he only had to circle the block around the refueling station and didn't need to haul anything. Compressed NG tanks are big and heavy while the natural gas didn't pack the punch to really haul the weight around. My friend(Bob) had his own Dodge Ram running on Liquid Propane Gas which was a much better way to drive in his opinion. As a long range commuter the Ram excelled and was very cost effective compared to gasoline. Login or Register to Remove Ads |

Re: electric motorcycles are coming to the USA
I saw a "Zero" motorcycle today in Sacramento. It looked rather well used, and it was noisier than I thought. Mostly just clanking, etc. no engine noise, of course. Was a dual sport style.

Re: electric motorcycles are coming to the USA
The clanking might be a good thing. It give folks a heads up that something is coming. I have had quiet electric scooters zoom past me on the sidewalk and scare me half to death. They need a piece of cardboard sticking into the spokes to make some noise.
