		<description>Sean,

I have not figured the fuel mileage yet but if it&#039;s anything like Jeff&#039;s diesel hydrostatic bike it should be fairly good.  Jeff&#039;s bike gets in the neighborhood of 80mpg to give you an idea.  

I always hear people make claims about how inefficient hydraulics are. Sure, some hydraulic components are inefficient but not all of them... some are very efficient!  If I had to guess, the system on my bike is probably in the mid 80% efficiency range.  Not too bad considering efficiency was obviously not the main goal when building this bike.  If it was, the bike would have a completely different look.

It&#039;s no different than a hot rod car or modified motorcycle. Believe it or not some people actually build vehicles with performance, looks and/or functionality being the main goal.... efficiency takes a back seat!

As for the weight and complexity....  The bike weighs 760 pounds.  How much does a loaded Harley weigh?  Complexity?  It&#039;s actually very simple!  One engine, one pump, one hydraulic wheel motor and a few hoses.  A Harley would have one engine, one clutch, one transmission filled with gears, 2 sprockets and one chain.  The hydrostatic system really isn&#039;t that complex, it just sounds like it to a person who isn&#039;t familiar with them.


Thanks for your comments,
Brian.</description>

		<description>I would be curious to know what kind of fuel mileage it gets compared to a gasoline bike with standard transmission. The increased efficiency of the turbo diesel being offset by the inefficiency of the hydraulic drive mechanism and extra weight/complexity.</description>

		<description>What would make this bike totally bad-ass, other than a seat, would be about a 36-inch front wheel to fill up that enormous empty space between the current wheel and the triple tree.

I mean, it&#039;s already not going to handle well on account of that Lamborghini tire on the back, so they might as well make it look neat ;)

		<description>Greybeard, 

You&#039;re right hydraulics CAN eventually leak but name a machine or vehicle that WONT eventually develop a leak. It doesn&#039;t matter if it&#039;s engine oil, transmission oil, brake fluid, etc, etc, any fluid CAN leak. We used quality hose and fittings on this bike to reduce the possibility of leaks. Not to mention... It&#039;s a mechanical machine, I&#039;ve yet to see ANY mechanical machine that was 100% perfect.  EVERYTHING eventually has a problem... Jeff has close to 9000 miles on his motorcycle and it hasn&#039;t leaked a drop yet.

Thanks,
Brian.</description>
