    I'm considering a custom made PB-960S, recently shown at the Taipei

    fit my size and weight. Comments/suggestions? Thanks.

    These are being imported to the US under the Actionbent label:

    The bikes in general look pretty good- but I didn't get a chance to
    test ride on at the Seattle show, so I can't really comment on the
    ride quality. The seat was comfortable enough in my test-sit.

    Just looking at the picture, though-
    http://www.recumbent.com.tw/HTM/pb-960s.htm
    I'd be worried about the size and material of the swingarm pivot. It
    *looks* very small and narrow. Also, the top run of the chain appears
    to come quite close to the right "chainstay"- I'd worry about the
    chain chewing it up.

    You might want to check out the discussions at:

    http://sports.groups.yahoo.com/group/actionbent/

    where there's a lot of discussion about bikes from this company, though
    not that model in particular.

    My impression of assembling a Tidal Wave frameset (still in progress) is
    that the bikes are decent quality and a good value, but there are some
    things that aren't quite dialed in yet.

    Notably -

    - some models have cable stops in the wrong place making them
    sub-optimal, or even useless (if you want to have bare cable runs common
    on upright bikes)

    - packaging/boxing from the factory could be improved (reports from the
    discussion group above would indicate that it's gotten better, but has
    room for improvement)

    - some USS steering models are limited in turing radius by an
    unnecesarily complex handlebar configuration (one of the most common
    mods people make)

    - the stock chain management works, but can be noisy, with many folks
    replacing idlers or modifying them to reduce noise (chain running over
    hard plastic idlers)

    - the vinyl covered padded hardshell seat would use some lateral
    support, or at least grippier material to prevent slipping sideways

    What, *another* discussion group to monitor? Yikes, there's already
    too many to read. ;-)

    That's what's neat about the PB-960S- no idlers, just chain tubes.
    However, I'd prefer an idler on the lower chain run instead of the
    tube- I've found that chain tubes are hard to keep clean if you use an
    oil-type lube. (This is my preference here in the Pacific Northwest.)

    Plastic idlers were the bane of my Lightning P-38- I had to replace
    them annually. Terracycle's tooling up to make precision
    steel/aluminum idlers: http://www.terracycle.com/parts.htm .
