Sorry, but I need a seat. I hate stand up riding on my bike if I can avaoid it. However, I would like to try out the pedal action on this system.

I sure they offer that pedal system on standard bikes.

Well, they\'ve solved the uncomfortable seat problem at least ...

This looks great, except for one thing: it looks like it would be _very_ easy to accidentally drag a pedal, especially the toe-end, since the ground clearance is so low.
If you drag that toe while going around a corner, you\'re almost certainly going to take a dive. Aside from that, I love it.

so, you\'ve mad a really ugly bike with no seat? you cant put this into the category as being as fun as a board sport, your just rolling down a hill on your seat less bike ha

Can\'t they just put a seat on there?

The pictures show rotating cranks and the description of \"sliding\" movement does not match the rotating movement of cranks, so I have no idea how this works. I doubt the rear foot can move forward and up slightly if the cranks rotate as they appear to be made to. Sliding would give up a lot of leverage too. The pictures and description are lacking if we are to understand how it works.
I don\'t see the point in eliminating the seat for anything other than a toy - which appears this is meant to be: \"combines the standing stance of things like skateboards and roller blades.\" For transportation conventional bikes have it all over this design. A lack of a seat is one of the fundamental weaknesses of the Segway for transportation over distances it would be better to just walk.

Imagine this drive on a Strida folding bike! Wow. The object is to get through traffic quickly and easily, right? Eliminating the seat means less junk to carry up and down stairs, less hardware to fold up, and it definitely looks like fun! This appears to be a remarkable advance. We need to further improve the human/bike energy interface anyway and this looks good enough to take a significant share of high end folding bikes for energetic, wealthy people. Generationz will thrill at this.

This bike is so great, It provides maximum torque at the top dead centre, least at the bottomest. I don\'t know, let the experts explain.

There are so many things wrong with this that it\'s hard to know where to start. His \"independent\" cranks are nothing more than a phase advance mechanism, so the upper crank is past top dead center as the lower crank hits bottom dead center. It\'s been tried for bicycles, and it wasn\'t successful. It introduces more friction and more complexity, so it\'s more prone to failure. Standing is inefficient from a power standpoint. With the hip angle open to 180 degrees, there\'s almost no involvement of the gluteals, the largest and strongest muscles in the body. All that rocking of the handlebars isn\'t good from a control perspective. Sure, they got one guy who practiced enough so he can zoom among crowds, but the vast majority of people may find it hard to ride straight. Plus those wheels are definitely not as big as a bicycle\'s, no matter what the designer says.
