No. 6 September - October 2004
stand at Interbike 2004, Las Vegas, USA.
couple of months have been very busy for us at Greenspeed as we
have been preparing for our largest show of the year at Intebike,
Las Vegas, this month, and also for the Bicycling Australia Show
in Melbourne last weekend. We have also been working very hard to
fill a container load of trikes for the USA market, so that they
can be sent to our USA distributor for immediate delivery to
shops. Hopefully this will reduce the waiting time for our trikes
in the USA. Plus we have been working on new models for next year
as usual. Here are some of the highlights of the past couple of

1. Pedal Prix
Last month I was invited to judge trikes at the
Australian International Pedal Prix at Murray Bridge, near Adelaide
in South Australia. This is the oldest Pedal Prix in Australia and
has been going for many years - see :-
The criteria used for design and construction
points were :- Design Process, Safety, Drive Train, Ergonomics,
Equipment, Aerodynamics, & Innovation. Unlike the Maryborough
event which is only open to schools, the SA Pedal Prix has a community or
open class, which I was judging. Most of these trikes were built by
young men who had left school, but had continued with their passion
of HPV racing.
I found that some had put an enormous amount of
time and effort into their machines, and there were some quite
interesting designs, which could be used as commuters. It was also
interesting to see that the carbon fibre designs were not the
lightest, proving that you do not need a big budget to produce a
winning machine. I rather liked the wing section trike (top), as
visibility was good and it avoided the need for compound curves.
2. Interbike Show
year we took a larger stand (booth) than in previous years so we
could display most of our large range of trikes. These were divided
into four categories :- Recreation & Commuting, Touring,
Sports, and Racing. Our USA Distributor, Jerome Hediger (bending in
the photo) and his wife
Nancy helped in the booth, and were introduced to our dealers.
Recumbent Cyclist News, Bent Rider On Line,
Recumbent & Tandem Rider, and Velo Vision took photographs
and notes of our new 2005 models, which will not be available until
sometime next year, due to production lead times and parts availability. So
please look for them in these publications.
3. No Punctures
The most interesting thing I found at Interbike
was a puncture proofing system, which gives LOWER rolling resistance
instead of higher rolling resistance as with all other systems I've
tested. How does it do this? Simple! It just removes the inner tube!
I discovered that using a thornproof tube DOUBLES the rolling
resistance of a good tyre, thus removing the tube completely ought
to make a significant difference to the rolling resistance. The
system uses a wide rim strip to seal the tyre from the rim, so that
an ordinary tyre will work like a tubeless tyre, without the need
for a special rim. Add some puncture sealant, and any punctures seal
as soon as they are made.
The only catch is the kits are only presently made
for 26" tyres. However, I bought one and found that the sealing
strip was not really needed, and I got a tyre to seal O.K. on an
ordinary 20" rim, without the sealing strip. Initial rolling
tests confirmed the reduction in rolling resistance. More tests will
need to be done to check to see how this system stands up to
everyday use, and to see if we can get the system to work with the
narrower 16" rims.
Ultimately it might work best with special rims
and disc wheels, like used on our race trikes, so that there are no
spoke holes in the rim, and no need for any sealing strips. For more
info., please see:-
We have just sent Stan "notubes" a number of rim and tyre
samples in both 20" and 16", so he will be working to
produce rim strips and kits to suit Greenspeed trikes. More info.
when these are available and have been tested.
This year the Bicycling Australia Bike Show was in
Melbourne, at the Royal Exhibition Buildings. IMO this magnificent
building makes it the best venue in Australia. Unfortunately I
take my camera, and I can't find any web sites that really do it
justice - this link might give some idea of the buildings :- http://www.deh.gov.au/heritage/worldheritage/sites/exhibition/
Taking a lead from Interbike, this year we had a
Demo Day down near the river, the day before the show, which gave shops
the opportunity to test ride bikes and trikes before the show opened.
Friday was trade day, and the Show was open to the public on
Saturday and Sunday. Both public days were quite busy, and there was
a test track at the show for the public. We had both the Brompton
folding bikes, and the Sun recumbent bikes on show for the 1st time.
Mick had put a lot of work into a new
Greenspeed catalogue, and when I saw it for the 1st time at
Interbike, I was suitably impressed, as were our booth visitors :-)
At 28 pages and in full colour we now finally have a brochure that
matches the quality of our trikes. So if you have a friend who does
not have access to the web, and who would you like to introduce to
Greenspeed, let me know and I'll send you one. It explains the
different categories of trikes that we make, has full page colours
photos of each model with a short description, and a full
specification comparison. And, on the last page..... photos of
all the crew!
6. SLR Race Trike
The new SLR race trike was shown at
Interbike and is now available to special order. It uses advanced
steering geometry that tilts the wheels into the corner as it turns,
so that both the rolling resistance through the corners is reduced,
and tyre grip is increased. The wheels also use negative camber, to
increase the track for stability within a narrow overall width. This
has the added benefit of making the trike less critical to wheel
alignment. The wheelbase is also extended to increase stability on
corners. Here is one owner's comments:-
"I told my wife that it is like a magic carpet ride. Mark's
descriptions of its handling are on target. Though I have
driven a Le Mans racing car, my sense is that the SLR's ride and
through corners must be comparable. It hugs the road.
I have not ridden with the lumbar support seats before and I find
that the seat perhaps enhances pedalling by stabilising movement.
I have driven seven different brands of trikes and the SLR is
clearly the finest performance trike I have pedalled."

We are getting some new tyres made which we have
designed especially for our trikes. These will be in a new size of
40-349 or 16" x 1 1/2" to give a better ride than the
current 16" x 1 3/8" tyres. The 1st samples of the new
tyres have been received, and were shown at Interbike. Testing on
our rolling resistance machine indicates a better rolling resistance
at 100 psi than any commercial tyre. We will be doing more testing
as we receive more samples in different
versions of this tyre. The tyre will be known as the
"Scorcher", and will be available by the end of the year.
We are also looking at a tubeless version of this
tyre which should have even lower rolling resistance, and will be more
puncture resistant than belted tyres.
The Arkel RT 60 Recumbent Panniers have been redesigned
with a new frame so that they hold their shape better and don't sag
when fully loaded. We now have new stocks of these bags for sale.
Price $375 AUD per pair.

9. New Bikes
Due to the increasing interest in both folding
bikes and recumbents, we have become the Australian Agent for both
Sun and Brompton bikes. So Australian shops may now buy both Sun
recumbent bikes, and Brompton folding bikes from us. Sun recumbents
provide entry level recumbent bikes. So for people who would like
some of the comfort of a trike, but are unsure if they want to
invest in the price of a trike, this may be the answer.
Bromptons on the other hand are the most compact
folding bikes available IMO, and are ideal for train commuting,
where they are very fast to fold, and take up very little space. Plus
they have rear suspension.
