Open Source Velomobile
Building the Shell
WHAT IS IT?
A way to radically reduce the cost of building a velomobile by using the Open Source system. Starting with a typical
recumbent trike (tadpole type) you add a fibre reinforced plastic shell that you can make yourself from a mould which you have borrowed at no charge from another hypertrike.org member.
Members are encouraged to copy the moulds and improve the design as they go which then passes on others who want to make their own Hypertrike. Cost for materials by those who use their own (free) labour is about 200 EUR (Ozzie $320, US $240) for fibreglass, polyster resin, rigid PU foam etc. more detail here!.
The chassis of the prototype is a stretched
version of a Logo trike but
the aim is for the shell to be applicable to as many tadpole trikes
as possible by way of simple changes as part of the basic design. You can even build your own sports trike using the "Thunderbolt" design from our Links page.
The Hypertrike project will (if it succeeds) greatly increase the
number of velomobile type personal transport vehicles in everyday use
by creating a design and constuction method that is easily copied by
individuals using commonly available materials and skills.
- Most of the urban utility of a
- Lockable, payload & rider
- Protection from tyre splash,
sunburn and rain
- High visibility to other traffic
- Higher collision protection than
- Aerodynamically efficient
- Beautiful shape
- Noise and Vibration countermeasures for the rider

HPV Homebuilders Forum. Have your say, leave me a message and
Build Your Own from Scratch with a Free Trike
I decided to support my local HPV builder, Logo Trikes but if you have no one in your area and don't want to freight one in, a free set
of plans to build a recumbent trike is at the International
Human Powered Vehicle Association.

While researching possible designs for
a Hypertrike I met Dr Pat Howden who kindly offered the electronic
version of his book which is jam packed with ideas and designs for
living an extremely low cost, sustainable life. Get

"Proof of Concept" only version of a Hypertrike - rear lockable luggage space but minimal aerodynamics and no lockable cockpit space.
