I have no vested interest in them, I just wondered if anyone else used them.

I work in an office setting which means a lot of time sitting and writing or running code. A few years back I picked up a desk cycle. The crank arms are short so that it can operate under a desk and magnetic resistance so it is quiet. I keep mine set on the highest resistance and will spend a couple of hours a day pedaling it.

Does anyone else use one of these things or similar?

No, but I'm curious about them. The ones I've seen have had seats on them that don't look like I would want to sit on 8 hours/day. Can you post a picture of yours? Are you on it all day, even when you're not pedalling?

Here's a flock of varieties, from dirt-cheap on up.

I guess I don't get how you could pedal them while sitting in an office chair.

A swivel chair, on casters? I don't know if you could. Anyone here tried it?

An office chair is very unlike a bike saddle. I imagine pedalling to be uncomfortable for real cyclists. Also the casters and swivelling will make it hard.
no experience, just a guess based on experience with a Schwinn stationary bike with a sit seat (not saddle).
There is a reason a bike saddle is the way it is.

Work station & bike parking:



Just add a resistance trainer.

Seen a simple crank stand it just rotates, no load , but you can have dreams of going somewhere..

As you can easily see, all these devices have straps/stirrups on their pedals. Once the feet are attached to the pedals, it is possible to spin the pedals even when sitting in an office chair on casters, even with artificial resistance produced by the device. If you do it properly (spin, do not mash) the net "recoil" from such device is zero, meaning that your chair will not roll back. The ergonomics of this thing is, of course, very different from that of a bicycle.

Wow! Clever!

I'm pretty sure none of my employers would have been too hip on the idea of using a desk cycle.
