Benefits of the GRIT Freedom Chair for amputee riders


Reduced fatigue

The GRIT Freedom Chair is significantly easier to push than a regular wheelchair. The ergonomic lever drive uses large muscle groups to reduce fatigue and keep you adventuring longer. The gear ratio is easy to change with off-the-shelf bike parts, so you can adapt your GRIT Freedom Chair to match your changing strength and ability levels.


30-Day Satisfaction Guarantee

We know you'll love your GRIT Freedom Chair, which is why we offer a 30 day "no questions asked" money back guarantee on most models. If you are not satisfied in any way, you can return your GRIT Freedom Chair in its original packaging for a full refund.
