The Hoopy can easily carry a passenger on the long seat and possibly even
another on the cross bar. Try doing that on a conventional bike! The plans
show how to fit a single speed rear wheel or the superb 2 speed SRAM
Automatix hub. The concise plans contain almost 30,000 words and well over 200
images taken during the actual build of a Hoopy.

Many of the bicycle parts used to make a Hoopy can be obtained from a
salvaged bicycle. The forks come from any 26" wheel bicycle so are extremely
common and easy to find. The exception to this is the crank assembly where
it is necessary to buy a few new parts which will cost about £100. Even so
with care and by using salvaged and secondhand parts it should be possible
to build a basic Hoopy for about £250. There is nothing particularly
difficult about building a Hoopy but it is a bicycle and even a simple
bicycle has many parts. It just takes a bit of time
The Hoopy is a lightweight wooden bicycle you can build yourself. It's very
comfortable and nice to ride with a surprising turn of speed. Its low frame
makes it very easy to get on and off and the strong yet light box section
plywood frame allows for an internal drive system, so no more greasy clothes.
No mudguards are needed and the frame can be used for storing tools, spares
or shopping. The Hoopy would be ideal for conversion to electric with the
batteries and motor easily housed in the frame. The design is highly
adaptable and allows for much personalisation.
The step by step illustrated instructions walk you through the entire
process from selecting wood to how to use epoxy glue. They include a lot of
further information on all aspects of the build, from the materials you need
and how to find and modify them. The box section frame may look complicated
to make but it is surprisingly simple. The frame can be marked up, cut and
glued ready for varnish in just two days. Pretty much the only tools needed
to make the frame are a drill and a jigsaw. The finished frame weighs from
just three kilos and yet is very strong. It is bonded using epoxy glue and
there is not one fastener in it.
The Hoopy is made from 10 mm plywood but the plans automatically adapt if
you use the Imperial equivilent of 3/8". The simple building jig ensures
that the frame remains aligned throughout the build. Two pieces of plywood 120 x 60 cm are needed and
there is little waste as the remainder of the frame pieces are made from
off-cuts. The photo on the left shows the pieces that make up
the head set assembly.
The Hoopy is a one size fits all bicycle suiting most adults of all sizes.
However if you wished a more tailored frame then there is the posibility to
either raise or lower the frame during the build and full instructions are
supplied showing how to find the ideal height and how to modify the design
accordingly. The Hoopy is an easy bicycle to personalise as well and the
plans explain how to cut your own design in the frame sides and offers
discussions and ways to modify your Hoopy to suit you.
