Product Description

Firefly Electric Handcycle Wheelchair attachment - Next Generation 2.0

The Firefly Attachable Electric Handcycle turns your everyday chair into a speed machine. Let the compact hub motor do the hard work while you steer.

Our unique "Quick Dock" attachment system easily transforms your chair to a handcycle and back again by connecting and disconnecting 2 latches. Our patent pending design ensures easy on and off of your everyday chair. The handcycle uses many off-the-shelf standard bicycle parts, which make it easy to service.

Designed to fit most folding / rigid, adult and pediatric chairs. Firefly has been improved so that it fits a wider range of width wheelchairs. Due to this improvement, you will notice the attachment arms are now more square in shape, for some pictures will show the old design with the round shaped attachment arms. All firefly's will come with the square shaped arms. 
For Installation here is a link to a Video. 

Attaches Quicker Than Ever Before

  1. BEST PERCHASE EVER! 5 out of 5

    Posted by Andrea Neumann Mascis on Apr 7th 2019

    I purchased this prior to my honeymoon to Disneyworld and the Firefly totally MADE my trip. Super light, easy to use once you get the hang of it, great battery life and really fast. It was amazing to be able to simply detach it and not have to transfer at all for many rides.
    The inital installation was tricky but a call to Andrew made everything run smoothly. Be forwarned to pay attention to the tips page that comes in your Firefly shipment. It will definately be a tremedous help and might even save you said call.
    The customer service cannot be matched and Andrew is wonderful and helpful. I will be purchasing from them again. Thank you so much!

  2. Best electric handcycle I've ever used. 5 out of 5

    Posted by Jessica Ortiz on Nov 2nd 2017

    I've tried quite a few electric handcycles at various abilities expos over the years and the new Firefly is by far my favorite. It's also a pretty decent price compared to some of the other ones out there. I really like how they changed the kickstand for this one. The older Firefly would lay on the floor, but this one stands upright, which makes it much easier to attach.

  3. Firefly 5 out of 5

    Posted by Unknown on Aug 22nd 2017

    I bought the Firefly next generation for a great friend of mine. She has been in a chair for 25 years. The mobility she has regained is awesome.

  4. Huge upgrade! 5 out of 5

    Posted by Harry on Jun 19th 2017

    I found the previous Firefly clumsy and it took a while to get used to them. This "Next Generation" is really easy to use. I like the 2 point attachment so much better than the 4. I'm not sure if the motor has changed, but this thing gets up and goes!

  5. Firefly next Generation 5 out of 5

    Posted by Carlo on Jun 5th 2017

    It is a good product, after you figure out all the different angles, to fit your chair ,along with getting the best weight on the front wheel, I explain why further in review. I do understand this is so it will fit many different wheelchairs. It does move riggt along nicely. The only problem i can see is because of my upper body weight, it make the front power wheel spin, going up a grade, of 3% or more, even in 1st gear. Other then that it is a lot of fun.

  6. Just clip on and go 5 out of 5

    Posted by Linda on May 11th 2017

    Love love love my Firefly! It is so awesome. I can stay in my regular chair and just attach this thing and my regular chair becomes fully motorized! I love that I don't have to push everywhere and I also love how easy this attaches/ detaches, so that I can go to a restaurant, and detach and sit up to the table like normal.

  7. Customer service 5 out of 5

    Posted by Buzz on May 11th 2017

    To me customer service is as important as the product. I called to get some information and found a company who had a large % of there employees being handy capped. When you speak to someone they have had first hand experience with there products. I was impressed because they knew what you where taking about and could deal with your concern on a one to one basis. They are a complete facility. They are worth a call . I was impressed.

  8. I'm touring all over the place 5 out of 5

    Posted by Jim Kent on Feb 16th 2017

    I've taken my new FireFly electric handcycle all over the place since I bought it in late 2016. The motor has WAY more torque than I expected. I was thinking of adding weights to the front wheel to give it more traction. I'm also looking into using a knobby tire on the front. I'm a tinkerer so I'm always looking for an edge. Lol

  9. Better design 5 out of 5

    Posted by Jordan White on Feb 13th 2017

    I've used both the old design and this new design, and this new design is way easier to disassemble and store. The problem with the old design was that when you went into a restaurant and left the firefly on the ground, the attachment arms would slide out, forcing the firefly to lay flat on the ground. That made it really hard for me to pick up the firefly while in my chair. This next generation firefly doesn't have this problem. The attachment arms function as a kickstand. It's way easier to attach the Firefly to my wheelchair now. If you don't have an electric handcycle for your wheelchair, I'd highly recommend the Firefly!

  10. WISH I HAD THIS EARLIER 5 out of 5

    Posted by Isaac Quin on Feb 6th 2017

    I wish I had this years ago to help my shoulders out.
