Overview

A tabletop or floor pedal exerciser with an adjustable magnetic resistance knob and a digital display tracking time, reps and calories, meant for arm pedaling at a desk or leg pedaling on the floor.

What sets it apart on paper from many simple pedal exercisers is the manual resistance knob combined with digital tracking, rather than a single fixed resistance and no readout.

  • Adjustable magnetic resistance knob
  • Digital display tracks time, reps and calories
  • Doubles as arm or leg pedal exerciser
  • Two-year manufacturer coverage

Who it's for

People wanting light upper or lower body movement at a desk or from a chair, including rehab-style use. Not for anyone looking for a serious cardio workout, since it's a compact pedal unit rather than a full exercise bike.

Pros and cons

Pros
  • Works for both arm and leg pedaling depending on placement
  • Adjustable resistance knob for customized effort
  • Compact tabletop design saves space

Performance notes

A manual knob adjusts magnetic resistance for either arm or leg pedaling depending on placement, and the built-in computer display tracks time, reps, total reps and calories burned so you can monitor a session at a glance.
