Think your Harley is the biggest bike on the road?  You’re not even close.  As of 2007, Greg Dunham holds the honor of owning the world’s tallest rideable motorcycle.  This makes a Hummer H1 seem quite practical, doesn’t it?

The 6,500lb. bike is pushed around by a 502ci big block.  It cost somewhere in the neighborhood of $300,000 to build, and believe it or not, Greg says it feels pretty stable when in motion.

Greg didn’t tell anybody about building it, not even his family –- he’s not big on naysayers, and we’re guessing the 300 grand he laid out might have had something to do with why he didn’t tell the missus.  Of course, if we had that kind of green in a 25-foot motorcycle we might not tell anyone until it was done either.

    Hmmm–are those training wheels I see on the back?

    Thats no motorcycle. Thats a truck with two very small wheels and two very big wheels. Motorcycles have 2 wheels.

    I’m betting those act as a kickstand when it’s standing still, and they retract when the thing is in motion and can stay up on it’s own.

    As ridiculous as this project seems, I have to admit I’ve done some home improvement projects that ended up costing 2-3x what a prefab doohickey from Lowes would have cost. But if you want it done a very specific way, and you have the $ to make it happen, why not. This guy just did it on a much grander scale.

    It actually has six wheels. The two rear wheels retract up while the motorcycle moves, there are however two more small wheels in parallel to the large rear wheel that appear to remain in contact with the ground at all times (I wasn’t listening to the sound but I think they have something to do with the ability to reverse the vehicle). There is a video after the link that describes the build process.

    That just looks like a toy mini-bike on steroids…fake “bigness”

    I don’t think it can beat the legendary “Road Dog” from the 60’s. Even today, 40 some years later, the looks of this thing rivals any hard-core biker custom built and it was built for touring!

    Trevor is correct. Watch the video; it isn’t a motorcycle.

    This is the ultimate definition of more money than sense.

    The Aussie Monster Motorbike from Hell is not as tall but is truly a motorcycle.
