    Worst recumbent trike ever made.

    I probably made a worse one as a kid, out of old bits of wood and pram
    wheels. ;-)

    There's the odd really shonky home-made one shows up on eBay from time
    to time too. Often saying something like "just needs the gears hooking
    up and the seat covering" when a cursory examination shows that the
    steering geometry is all wrong, the crank boom is going to be way too
    flexy or similar basic design faults.

    What about getting a longer handlebar stem?

  8. (a) Not generally available and (b) often means that the cables no
    longer reach. Most of the seriously long stems are available only
    for folders (and occasionally MTBs), and do no more than compensate
    for the miniscule frames. Oh, yes, you USED to be able to get them,
    but every one that I have seen recommended recently has either been
    far too small or more-or-less restricted to small-frame bicycles.

    For a 6' rider, one is looking for handlebars that are 4'6"-5'
    above the ground (depending on arm length) to get an upright
    position with straight handlebars. That means stems of quite
    ridiculous lengths.

    Or just fit something like this http://www.ebay.co.uk/itm/390688135950

    It looks pretty cool, but you'll still get the problem Nick mentioned
    about the cables not reaching. ;-)

  11. Plus the fact that it vastly increases the risk of clipping the
    handlebar on something, or having it clipped by something, and
    ending up in A&E or the morgue. Not to say its incompatibility
    with most 'cycle facilities', and general discomfort in use.

    Back when ape hangers were first invented, people rapidly found
    that they weren't particularly functional.

    I have one of these.

    http://www.sjscycles.co.uk/satori-handle-stem-easy-up-1-1-8-inch-
    adjustable-stem-raiser-prod23752/

    And a super short stem similar to this in length.

    http://www.sjscycles.co.uk/shimano-pro-atherton-1-1-8-inch-ahead-stem-0-
    deg-318mm-clamp-prod23335/

    Dramatically shortens the cockpit area resulting in more upright posture.

  13. Well, yes - they turn a deep crouch into a less deep one. Sorry,
    but they don't even get to first base. The further forward the
    handlebars are from the stem line, the higher they need to be.
    As I said, they should be something like 6" behind and 6" above
    the saddle, or some such combination.

    For some people, a half-crouch is fine - but, for many others,
    upright means upright. That is what the official line is for
    sitting position for VDU working, after all.

  14. 22" enough? :)
    http://t-cycle.com/handlebars-stems...t-p-104.html?zenid=0r97h5t1pfiidtkj70s9kvk793

    This will only do 11", but is more reasonably priced:
    http://www.ebay.co.uk/itm/PROMAX-EX...M-25-4MM-/261215996048?_trksid=p2054897.l4275

    Then maybe another inch from handlebars with a modest rise:
    http://www.bikeradar.com/gear/categ...leigh-north-rounder-alloy-handlebar-10-35382/

    I would have thought that was enough to get to the right hand posture of:

    (Fitting longer cables is trivial, even if another annoying expense which
    could be avoided if you could buy a suitably fitted bike in the first place.)

    I think I'd be tempted by a Pedersen if I wanted a really upright bike,
    but I'd want to try one first, and they aren't easy to find:

    I have to sit upright. My shoulder and elbow arthritis make a crouch
    impracticable for more than about 10 seconds.
    One solution we used to use was racing-style drop handlebars, installed
    upside-down so that the drops are now raises. Of course this means
    getting inventive with where to put brake and gear-shifter levers --
    As for the problem of cables being too short, whenever I have replaced
    cables I have always had to cut them. It seems that cables are made
    deliberately long to fit anything in the first place!

    It MIGHT be, but only in combination with swept back handlebars.
    The longer the stem extension, the deeper that you need to insert
    the stem into the steering tube, especially with aluminium.
    M-BICYCLE-22-2MM-25-4MM-/261215996048?_trksid=p2054897.l4275

    A complete joke for such a purpose.
    oduct/review-raleigh-north-rounder-alloy-handlebar-10-35382/

    The distance back is more important, and those are very little swept.
    It is possible that they would be enough, in combination with the
    first, starting from a standard UK frame, but I wouldn't bet on it.
    Except possibly for the combination of the first and last, you
    would think wrong for any rider above 6'. My bicycle has 10" of
    stem showing on a 26" frame, more raised and much more swept
    handlebars than the above, and is still not quite enough. And
    I am under 6'2".
    Ha, bloody, ha! Firstly get them - the only ones available are
    derailleur cables, and some forms of them are tricky to get. I tried
    at one stage, and gave up. Also, lot of cables come with fittings on
    BOTH ends; while it is usually possibly to cut longer cables and
    jury-rig something, it is definitely tricky even for a fairly good
    bicycle mechanic.
    That's nowhere near fully upright - look at it, for heaven's sake!
    It was designed for a semi-crouch position, in the days before the
    arse-over-tit position became popular. And most people want a more
    practical bicycle, anyway.


    Yes, and they often don't work at all well :-( As I posted a while
    back, the popularity of that hack WASN'T just that it 'looked cool',
    but a lot of people were suckered into buying drop-handlebar bicycles
    only to discover that they were unpleasant, or even impossible or
    excruciatingly painful, to ride.
    Some are, yes. That's partly because, when doing such things, you
    have to buy 'universal' or back brake cables for the front and often
    derailleur cables for the back. You probably have a short wheelbase
    bicycle, so the latter is less important - mine is 46", which is
    about the minimum for reasonable braking for someone of 6+' and an
    upright position.

    I'll just point you in this direction:

  18. I suggest that you actually read that before being so ridiculous.
    The title of the very first hit is "Sit Back, It's Better for Your
    Back", and the first paragraph includes a sentence "Instead, the
    best position for your back is somewhat reclined, sitting at a 135-
    degree angle rather than the 90-degree angle most office chairs are
    designed for."

    I have known that for decades, it is critical to me, and it is one
    of the lesser reasons that I am intending to buy a recumbent. But
    it is not feasible on a normal bicycle.

    But surely you realise that a UK cycling crouch is the OPPOSITE of
    reclining back, not the same?

    Furthermore, the problems with a crouch (partial or otherwise) do
    not typically show up in back pain, because riders can and do
    support their weight on their hands. The show up in neck, shoulder,
    elbow and wrist problems, because our upper limbs are NOT adapted
    to that form of load bearing.

    Nick Maclaren.

  20. You are wrong. It has the following relevant points:

    Most people (not all) can hold their spines upright for long
    periods, whether or not that is optimal.
    The reason for that rule is that most people cannot lean forward
    for long periods without pain.
    The reason that most UK cyclists carry weight on their hands is
    because not doing so causes back pain.

    Nick Maclaren.
