Meet the Firefly: an electric handcycle that attaches to wheelchairs, allowing users to go twice as fast a power wheelchair. It has a max speed of 12mph and lets riders go uphill with less effort. The Firefly has an adjustable design and gives you a lot of room to maneuver.
As you can see in this video, the Firefly is easy to attach. When you are done with it, simply put it in the trunk of your car. What do you think? Grab or pass?
