Human body front area depending on pose in case it will be possible to ride in horizontal position drag must be way smaller as front area will be at least 5x smaller.

Pardo face down HPV design.

Prone bicycle or archived - that's it...

This one seems to be produced still

Edit: Found similar prototype would like to get or build on YouTube 7 Crazy bikes

Is there anything between Twicycle and Streetflyer Streetflyer
Or at least Streetflyer with pedals ? Strange why it is missing 'em ??

Twicycle: Twicycle

Any hints for construction or building options ?

    Is there a question, or is this another link spam post? Why is there a identify-this-bike tag? – ojs Sep 15 '19 at 12:17

    Tom, you linked to a 10-minute Youtube vid. Few people on the internet are willing to watch a whole 10 minute video to search for one item. You can link to a specific time in YouTube vids by clicking share, and checking the box that says share from a specific time. I think you mean something like the Streetflyer bike at 6m 33s in the vid. Clarify if not. Clearly, I'm one of those odd people who's willing to pore through some content, but you need to make it easier for others to understand what you're posting. youtu.be/fGS2SgiLG80?t=393 – Weiwen Ng Sep 15 '19 at 19:03

    I removed "identify this bike" because there's no picture of a bike to identify. – Criggie Sep 15 '19 at 19:43

    @Tom please ask new questions as a new question, rather than editing a new question into an old one. – Swifty Sep 15 '19 at 20:40

    @Tom please understand I am not in a gang and having just checked, I have not down-voted a single one of your posts. I and several others have given suggestions on how to improve your questions inline with the norms of this site but you continue to ignore that advice. If you start to accept people's advice you might get more upvotes and be able to ask new questions. – Swifty Sep 16 '19 at 7:06

There are two positions which could be called Superman.

  1. enter image description herethe Boardman one which has the arms pointing way forward like Superman in flight but the legs still pedal. This is an aggressive aero timetrial position using a long stem and ski-pole length aerobars to reduce the angle of the upper arm respective to the incoming air - essentially reducing the effective frontal area.

Note his head is looking forward but his spine is flattish and angled down at the top. This is a horribly uncomfortable position in which to ride. Here thats okay because he's on a track with no road traffic (its likely he's alone on the track.)

The saddle in use is hard to see but its nothing special - he's still pedalling so a normal time-trial saddle will be used. Weight is still important, but there are no climbs on a track. Instead its all about getting the rider into their most aerodynamic position possible, and then allowing whatever comfort is possible without affecting their aero position.

  1. there's the viral-video position which is essentially planking on the bike, coasting with one's legs out the back like an airplane tail.


As you can see - that's Michael Guerra (left, in yellow) riding a vigorelli fixed gear road bike. There's nothing special about his saddle, which can be glimpsed in the full video

In no way is this a good idea on a road, or anywhere uncontrolled. Boardman's bike is a track bike, with no gears and no brakes. This is workable because the track is isolated.

Doing this kind of thing on the road is foolish, and risks yourself, and worse, risks others. Notice that any emergency reaction will have him off the bike because there is no third point of contact with the feet, and the saddle contact is only gravity. At the end of the video, they have to divert around a mobility scooter and frankly have insufficient margin for error.

If you intend to ride like this on the road, just don't.

    Both guys' gene sharing abilities might become slightly impaired. These two are rather candidates for the Darwin Award. – Carel Aug 17 '19 at 14:51
