Let the hive mind of Engadget get that for you.
"For a long time I have been searching for a portable device where I can store all of my CDs in MP3 format and stream the songs wirelessly to my HiFi system. The portable device must I've tried FM transmitters, they all suck. I don't want a docking station. Any help? Thanks!" have a display so that I easily can scroll through the playlists (I don't want to use a TV or monitor). I suppose that there must also be a second device that is connected to the HiFi system that would receive the wireless streams from the portable device.
Anyway from what I can figure, it folds by:
Pivot 1 on the back wheel axle, and pivot 2 on the circular thing below the saddle.
Fold down at pivot 1 until pivot 2 meets the chainring. Then continue to fold pivot 2 so the front end of the bike wraps all the way underneath. Pretty simple really.
The back wheel is likely a one-sided fixed axle much like the front wheel, with fork on one side only.
Also, the thing looks tiny. BMX sized wheels?
