Well; this is my first post in the recumbent section, and I wanted to share what got me into cycling-racing recumbents.

My school takes part in an event called the RACV Energy Breakthrough. We have 2 recumbent trikes entered into the Hybrid section. They are constructed of 4130 Chro-Mo, and Carbon Fiber. They are fully faired and with petrol engines.
We are entered in a 24 hour race, given 3l of fuel. The aim of the event is to create an environmentally friendly, efficient alternative means of transport. I am the manager of the program at school, and I'm responsible for construction, sponsors, e.t.c.

But this is a school only event. There are many more HPV only events around AUS, and I'm n a team that does most of them. Heres a pic of the carbon/kevlar monoQ vehicle I'm racing for 2010; "The Fog Bandit"

I've also started a community team, and our carbon kevlar monocoque fully faired vehicle is currently, about 85% complete. It will be raced in 2 24 hour races, and about 4 6 hour races. It weighs about 19kg at present, with a final weight around 22kg. We see average speeds on not so technical courses around 50km/h, and on technical courses, about 45km/h.

I find it amusing that recumbents got me into DF riding, and now I race DF rather successfully-but HPV is what I love.
I'll probably come back to this thread with more pics, e.t.c. of our hybrids, and my HPV, later on. Any q's feel free to ask/pm!

Until then, check out http://www.youtube.com/user/OberonRacing for some vids of our hybrids, and http://www.roderage.com.au to see a pedal/electric hybrid that crossed Australia to raise money for several charities and promote awareness about the enhanced greenhouse effect. That design is also identical to the hpv I was given, on the exterior. On the interior, mine has less stuff, and it's much lighter.

I assume that weird hump is there to accommodate the roll bar that I see on just about all those Australian HPVs. Assuming the rule is there to ensure a minimum head clearance when the rolled vehicle is tipped with it's nose to the ground, can you just put two lower roll bars... one behind and one in front of the head?

Yeah, made to fit rollbars with appropriate stupid head clearences. This particular fairing design is available for sale here in Aus, many teams using it are not able to utilise composite rollbars like we do due to lack of experiance/knowledge. So they use metal-the "hump" accommodates both potential designs. We have opted for the integrated composite bar.

There are smaller vehicles with a much much lower ride height (under 800mm in some cases) but the external rollbar required to use these setups make them marginally slower in the straights then this design. However, the shorter designs handle better, or at least that is the prevailing theory. I found this design would grip really well, but it welt like it was pitching over a little through some of the hairpins.

Very cool. :thumb: I'm always keen to see various faired HPVs in action.
