    When I was riding for Mongoose, we did some shows up at Mammoth for a NORBA race. After the shows we raced our bmx bikes down the mountain (on the paved road)... We had the suburban follow us, and on the last straight we were clocked doing 60mph.

    I bet that thing will bring the speed!

    My first goal is to get it over 40mph and see if it disinegrates, if not it's game on there are people riding full fairng gravity bikes hiting 100+ mph.

    I'm thinking that at the speeds that thing can reach, 65mm of (at least) front suspension would be a good thing...even if it's w/ the firmest springs and compression setting.

    Heh heh, that roadie in the second test was looking back at you with a twinge of jealousy in his eye.

    When are we going to see the Flagstaff Mtn test? Now that would be really cool!

    My next test will probably be pole hill road up by lake carter. But don't you worry because flagstaff is on my short list.

    I got to push/ride it around a bit today. I reeeaaaalllllly want to try it out on a hill. GiantSaam is right - out of control fun. It'd be like bombing a hill on a lifesize 2 wheeled pinewood derby car with brakes. Takes shuttling to a new level.

    Since you didn't have a second camera, please provide some color commentary.Were you wearing a lycra race kit too? Was the roadie pedaling hard to catch you? Was the roadie checkin the bike out or you?
    I am impressed you have just taken it to another level.

    Unfortunately no because my gps was dead. I can tell you I was pretty close to 45 or so because I reched 50 on my road bike on that hill the week before. It also took me 15:30 to walk up it at 3-4mph average and 1:08-1:20 to come down.

    1 - you need a job.

    2 - that looks like fun

    I think Magnolia Rd should be the next test vid.

    Call me crazy, but I just had a really cool idea. What if you found another frame and made it into a gravity tall bike? Now that would be some hair raising fun! I do understand that would sort of defeat the purpose, but you know it would be blast.

    1 - I think you need to make one too.

    2 - There would be no need for crack in this world if evreyone rode a gravity bike.

    No, no! Those are all way too nice. Time to go dumpster diving and pick up an old bmx frame. Slap it on top and away you go... down Flagstaff... Oh man, I would hate to think of how a tall gravity bike would handle the corners on Flagstaff. But it would be quite interesting.

    Ok that looks like way too much fun. But it needs disk brakes. And you need to get yourself some leathers. I want to see some knee dragging action around corners.

    yeah I do plus if I get over 60mph I think I might invest in some leathers.

    For top speed it's got to be Lee Hill Drive... start at the top at the intersection with deer trail? then head toward Boulder, pick up your speed for a few turns then on the long straight before the uphill right-hander it's easy to hit 60mph on a roadbike so I'd guess 65+ on that thing.

    You've graduated. Now it's time to add fairings. I hope you don't have some plan to make something cheesy out of cardboard. This bike deserves metal, if not carbon!

    When your ready let me know. You have to come up here and do the the back side of Rist canyon down to Stove Prairie Rd. Road bikes hit 60mph all the time going down it.
