    Neat looking bike. The website says it has "tight turning ark [sic]". On presumes they mean small
    turning circle and not some Old Testament article. %^)

    The amount of leg overlap with the front would seem to make sharp turns difficult to
    negotiate, though.

    But does it have the proper weight distribution to be held overhead with one hand?

  5. I don't see a step-up mid drive, so the high gear is somewhere in the 80-inch range. I'd refer
    to it as a 'Starbuck's Racer.' For best effect, leave it on the SUV's roof rack while you're in
    the shoppe.

    This could be a job for Shimano Caprio or a 70 tooth chainring.

    Thank you John Foltz for the above. Really brought out a laugh. And the sad part about it is that it
    is so true.

  9. John, I know you perfer big gears but the gears are not that bad. The gear range probably isn't
    enough to win at HPV races but it should be sufficient for 25mph (100rpm) with sprints to 30mph
    (120rpm). I perfer to cruise around 90rpm so the gears would be suffient if a little low for any
    down grades. Plus as was mentioned other gearing options are available such as 70+ tooth chainrings,
    SpeedDrive, Dual-Drive, Caprio. It looks like a good lowracer for a small person but the BB looks
    too low for someone my size. If you have to extend the boom ny further then it appears that your
    heels will hit the ground. I'd perfer to see the boom extend stright out from the headtube instead
    of down. That way seat to BB heights don't change instead of getting less for larger riders as the
    current design.

    If you know I like big gears, you probably know why: I hate using that 11T, and I don't much like
    the 12T either. They're too hard on the chain, and you know killing a chain takes a lot of
    energy. I can just feel that energy getting sucked out of my legs! Well, not really, but you get
    what I mean...

    I ran the numbers through my gear calculator. A 28x349 tire (if that's what it is,) is almost 16
    real inches (15.9.) With a 60/11, that'd give an 87" top gear, good for 23 mph at 90 rpm and 30.9 at
    120 rpm. I'm afraid I'd need a bit more. And, as I wrote above, I'd be very unhappy running around
    everywhere in high gear, or maybe downshifting to my 60/13 on a hill. But I'm sure it would work
    well for a lot of people

    I agree that the bike looks interesting. Potentially a good platform for spinners or un-tall people.

    It's an old "Weight Weenie" trick to build up the bike as light as possible, wheter it's useful or
    not, then make a splash with a low figure. Then you quietly add in things like rear brakes and Dual
    Drive or Schlumpf.

    Another option would be that short cranks significantly raise the comfortable RPM.

    We may joke about it, but it should be possible to produce a useful sub 20lb version, which is
    nothing to sneeze at. And besides, it does look kinda neat.

    Even though it's been done before, offsetting the fork legs, rearward at the crown is a great
    idea for FWD.

    BTW here's another 18.0 lb Chromo low racer. This weight includes rear brake, mid drive, a rather
    heavy steel stem and dual mirrors (req'd for HPRa competition)
    mnhpva.orgSherrie.jpg Built by Ray Brick for wife Sherrie. She's quite light and
    only about 5'1" so he could use main tubes that are only 1.375" x 0.035". Some of the weight savings
    comes from tricks like using a piece of 1.25" x 0.035" for a BB shell, reaming the shell with
    headset tools and pressing the 30mm OD bearings in w/o cups. Also the frame design is a more
    efficient use of materials than the Nitro.
