This is a magnetic workout pedaller (not a complete indoor bike - just pedal equipment for working out legs and arms while seated on the couch or in a chair). Here's the original specs from Amazon (presently priced at $149):.

　　I bought it in 2013 and then was given a hand-me-down recumbent bike, so no longer need this. Works great - odometer keeps an eye on time, speed, and range. All magnetic, so no plug or battery required. Much less costly and smaller sized than a complete exercise bike.

　　Features foot pedals and optional hand grips for working out arms/shoulders. Great for physical treatment, getting exercise while studying or while seated at a desk at work, or for reducing regret while vegging out on the couch all weekend.
