Overview
A lightweight chrome pedal exerciser for seated arm or leg cycling, with an adjustable tension knob and pedal safety straps, aimed at rehab, physical therapy, and low-impact home use.
- About 6 lbs, compact for home or office
- Adjustable resistance via top-mounted knob
- Non-slip pedal straps for hands or feet
- Works from a wheelchair or seated chair
Who it's for
People in physical therapy or post-surgery rehab, older adults wanting low-impact circulation exercise, and wheelchair users who can pedal from a seated position. Not for anyone needing high, consistent resistance, since the tension knob reportedly slips.
What buyers say
From Amazon customer reviews.
