Hi I wanted to ask you if you can show how the dragonfly mounts on the wheel chair in detail, the reason i ask is because I am am in pursuit of a mechanical engineering degree and im taking this class called "design practice" and i wanted to do an analysis in this simple and easy docking system and maybe improve the design for my project, thanks in advance looks like alot of fun
there is a new hand bike coming to the public soon. it will travel up hills and attaches to a regular w-chair with only one lever. Wait till you see the inventor going up a hill with an extra 100 pounds of weight on his lap. the test videos are being made and will be made public soon.
Hummm!!! I buy my Roi dragonfly 2 years ago, and i enjoy it very much.... ofcaose it can not have much weigh on the front wheel, but it works very well on flat terrain and also on a little bit ophill.
I think you have make something wrong about the ajustment to your wheelchair.
I live in thailand in 4 month in the vinter, and have the Dragonfly with me. And I use my Dragonfly for at least 10-15 km drive every day. My house is even on at place where it' goes ophill.
It's not only Dragonfly handbike there have this problem.. ALL handbike for conection to front of a wheelchair have similar problem, and are only good for use on nearly flat terrain.
But for some wheelchairs you can buy adabter for the back wheels, so you can move the wheels 25-35 backwards. If you use that i can garanti you that your dragonfly wheel will not spin. I have try it my self, and i works very good, But you need alot of muscle power and low gear to go uphill :-)

I just purchased one and like it very much. I primarily wanted one for rough terrain to by-pass those poor conventional front casters on my wheelchair. The bigger front wheel seems to work well on grass, dirt, and small gravel. I wish the dragonfly had existed when I spent $3000+ on a heavy all-terrain wheelchair. This did the job at half the cost and probably with much more efficiency.
