This page will
tell you something about the tricycle conversion.
last 100 or so years there have been some tricycles produced
with two wheels at the front - a layout sometimes called
"tadpole" and sometimes incorrectly called a "Kendrick"
after a notable maker in the early 20th century; their lack
of success probably owes more to the development of a
suitable differential axle and to poorly designed steering
than to anything else. The Newton conversion uses an
Ackermann-type steering, just like a car, and, while
steering and riding any trike takes a little time to
get used to, the steering of the Newton is extremely good
and the handling is better than most "conventional" trikes.
The Newton conversion
fitted to a gents light touring
are three main advantages in the "2-front-wheels" layout -
firstly, the drive is applied to the centre-line of the
machine, which is not the case with many cheaper
conventional trikes using single-wheel drive, additionally,
any conventional cycle transmission can be used. The
second advantage is in weight distribution, firstly the
weight on the driving wheel is increased, giving better
traction, and secondly weight transfer when cornering is
much easier - if the inside wheel starts to lift on a
corner, you simply lean your weight onto the inside
handlebar. A related issue is that if the machine
lifts a wheel, it tilts diagonally towards the rear, whereas
a conventional trike tilts towards the front - since
generally you are going forwards, your momentum makes the
conventional machine more likely to overturn. Finally,
the braking is far superior, now using mechanical disc
brakes as standard on both front wheels, giving much greater
safety - by contrast, many cheaper "conventional" trikes
only brake one of their back wheels, some even have 2 brakes
fitted to the front wheel and none on the rear!
of the conversion are high quality cycle tubing from
(among others) Reynolds and Columbus, bronze welded.
The conversion is designed to fit a standard frame 21"
(53cm) or over in size, and using wheels in the range from
24" to 27", including ATB sizes. It fits onto the
bicycle by removing the complete front fork assembly and
attaches by means of a clamp at the head tube and another
at the bottom bracket. The conversion set weighs
around 8.7 Kg, whereas a typical front fork, wheel and
brake assembly weighs around 3 Kg, so the increase in
weight over a standard bike is about 5½ Kg or 12
lbs. The front wheel track is about 27" (68cm), and
the overall width is about 33" (84cm) when travelling in a
straight line. The complete machine can be got
through a doorway as narrow as 29" (74cm) by turning the
front wheels. For this conversion, which is also
available for aluminium frames, we prefer to have the
frame here to ensure a good fit.
can also offer a permanent conversion welded on to your
bike frame, which is neater, stronger and slightly lighter
- of course, to do this, we have to have the cycle frame
here. We can't guarantee to match original paint
finishes or to preserve original logos on the frame.
We can't offer a welded conversion on aluminum frames.
take about 6 weeks from order, but please contact us for
