I think it might be on Netflix.

Looks rather like Graeme Obree's world record attempt cycle.

he finally got a drive train put on that thing, huh ?


Yes, an interesting design. It does appear to be about as
aerodynamically perfect as possible.

It will be interesting to see if the aerodynamic benefits outweigh the
physiological/biomechanical disadvantages.- Hide quoted text -

doubt it is very effective up a good climb, and the longer wheelbase
will kill in steep switchbacks

try bunny hopping a pothole or a curb or the broken asphalt at a
railroad crossing

if its impractical it is useless

What disadvantages do you see? Apart from resting on your stomach it
looks pretty much ideal.

Well, admittedly I haven't seen the video (lacking the required

From the guys website: (see http://www.h-zontal.com/pagesgb/faq.html)

"What are the disadvantages ?
First, you cannot rest your head and at the same time see the
landscape.
Secondly, piloting with mirror is not straightforward especially in
descents.
The actual version of H-Zontal bike is not good for long ride, but it
will be improved :
The mirror system is not yet perfect, but if it was built by a goggle
industry, the vision wil be improved.
The hips support needs improvement for long rides.
Then, when your hips hurts, you cannot stand up for a long time to
allay the pain."

I was referring to Obree's world record attempt bike which looks ideally
suited for its purpose.

For riding on the road , horizontal & head first doesn't look great to me.

Pete-

why head first as opposed to feet first ?

aerodynamically, head 1st, the head up convention in obrees position
spoils the flow, a prism/mirror contraption keeping the head down
seems more efficent

we are used to seeing rockets and other projectilles conically shaped-
so again I would expect a feet first approach unless obree adopts a
superman position

not that I really care though- it's not a bike I would ever care to
ride

Shoulders are the widest part of body, therefore need to be at the front
for lowest drag - aka the teardrop shape.
