Really cool Nordic Track Fitness Bike.
This bike has a number of neat features which may not be readily apparent:
9 Speed Radial Gear
Meaning the chainrings expand and contract to change gears with a chain tensioner on the back to take up the slack.
Rim Brake
A contracting band brake which drags on the rim
It also has assymetric cranks and few other weird parts. While not explicitly availably for test rides, it's worth noting that it is fully ridable.
