The Firefly Power Handcycle has the ability to turn almost any wheelchair into an electric-powered chair. This power handcycle attachment is lightweight and fully based on electric power. It can generate speeds which are up to twice as fast as those of a power wheelchair. Simply snap the attachment onto a wheelchair using the patented attachment system, and you’re ready to go. The handcycle can take you wherever you want to go, including over rough terrain or up steep gradients. It’s a great way to get extra power to your wheelchair, and to give your arms a break when you’re tired of wheeling yourself.
