    Attaching chair to handbike!

    I had this idea to attach my chair to my bike this way for YEARS, but was unable to find the right kind of clamps. I needed right-angle clamps - which are pretty common - but I needed them for the 1" OD (outside diameter) tubes of the bike axle and the chair frame. Every one of the right-angle clamps I found were for tubing 1-3/8" OD or larger. I called, visited, and looked online at Grainger, McMaster-Carr, scaffolding suppliers, rigging companies, plumbing suppliers… anywhere they used metal tubes or pipes. No one had right angle clamps that small - or even normal clamps that small that could be bolted together.

    I thought it was over. I thought I'd never be able to find right-angle clamps the right size. I almost gave up. But then I got a call from a guy at a scaffolding company I spoke to over a month ago. He said someone in the office was a musician and thought a drum store might carry something like what I was looking for.

    Well, after years of coming up empty I was doubtful, but I headed over to a specialty drum store about 2 miles from my house. I chatted with the manager for a bit and told him what I was looking for. He pulled a couple things they had and they weren't quite what I needed. But then after looking around his store a bit he said, "hey, what about this?"

    It was perfect. A DW Drums MG-1 clamp. It was exactly what I needed; the clamp that had been haunting my dreams for the past decade. He sold me a pair for $25 each and if I could, I would have been skipping out to my car like a little girl full of lollipops and bubblegum.

    So this is what I do now.
    *note: my generation of Freedom Ryder has rear wheels that use standard quick release axles. This means that I only need to take one set of wheels with me! If your bike doesn't do this, I'm sure you could strap the chair wheels to the chair frame somehow.










    The wing nuts are very big! I think a quad could use them. Even if the chair isn't screwed on tight, it'll stay. I've arrived at my destination and realized it was a little lose once. It'll just rattle around a bit more.







    If I ever want to ride without the chair I take it off and screw the clamps down tight.





    So here's what happens:
    I have an extra chair which I keep clamped to my handbike. All I need to do is xfer to the bike and I'm ready to go. When I arrive at my destination…
    1. Un-clamp the chair from the bike (it's actually easier to do this while still on the bike)
    2. Get off the bike onto the ground (or bench if there's one around)
    3. Take the wheels off the bike
    4. Put the bike wheels on the chair
    5. Get in the chair
    6. Lock up my bike
    7. GO!

    The whole process takes about 7-10 minutes, which is great. Now I can actually bike to places instead of making a loop back to my car or home. I can ride my bike to shows, concerts, parties, dinners, friends' houses. I can ride with my friends and get a beer at the bar after. I ride by handbike to work 3-4 days a week now. It's FANTASTIC! So much freedom! So much flexibility!

    You can find the DW Drums MG-1 clamps online for about $33 or at your local drum shop.







    I do clamp the chair so that the casters are off the ground. This is because casters are noisy on streets and I'd rather not wear them down.






    You should do this! It is awesome! Any questions?

    That's a pretty cool and very ingenious setup. I'm no where near setting that up for myself, but I'm curious: The wheels on the wheelchair only have two bearings, correct? So, wouldnt that make them not as reliable for holding up to the type of riding you would need for street-riding/handcycling?

      I am totally impressed!! I love adaptations like this - have long thought about a "gadjet wheelchair" with hidden equipment.
      Yours is a remarkable idea and hope you have more of them........

        So you get where you are going and transfer to ground take wheels off bike, put on chair and transfer from ground to chair? I have never even worked on ground to chair transfer but pretty sure I would be hard pressed to pull that off. Glad you found the clamps. A video would be nice if you had the time, of you getting off bike and into chair once you get where you are going...

          Excellent!!!

          This has been part of my next plan also.
          • I want to carry the frame of the wheelchair and use the handcycle wheels and cushion, just as you have.
          • I want to use the Power Pod to enable the trip to be longer, faster and more enjoyable - especially given the extra weight of the chair.

          The goal would be to be able to go touring with friends, to a lake (for example), where we spend the day swimming and eating food, then cycle back.


          Good find with those clamps....I spent a long time looking for the right clamps for my Power Pod, so I know what you went through lol

            Well done on figuring that all out. I love it when things like that finally come together with the most unlikely stuff, especially non-medical stuff.

              I use the handcycle wheels on the chair, not the chair wheels on the handcycle. Either way, the handcycle wheels use the same hubs as the chair with 2 bearings each. I'm not sure what you're used to, but they work fine. I don't know that a hub with more bearings would be any better.

              Yes. I highly recommend learning to xfer from the floor - for many reasons. Search on Youtube for "floor to chair transfer" and you'll find a bunch of videos showing different ways to do it. I put the chair behind me, bump up and sit on the footrest, then push up to the seat.

              Yes, I can absolutely feel the difference when the chair is on the back, but it's not terrible. I can still get close to my normal average speed. If anything I figure I'm getting more of a workout.

                So where did you get the clamps? I could see needing some of those might buy a set to have on hand if you can point me in the right direction

                  Why don't you want to attach the footrest to the back of the cycle and tow the chair on its own wheels. That's what I do behind my lawn mower.

                    Thanks Brian, that's interesting to know. I try to read what you guys post about handcycles: One day I'd really like to get one. I'm not very mechanicaly inclined; I assumed and thought I read on somebody's post about handcycle wheels having more bearings. I thought that's what made them ride better and faster than our everyday wheelchairs. I also thought I read on somebody's post a comment about their wheelchair not being able to hold up to the beating of going down hills or racing because of the bearings. Very interesting!: Now I won't misstrust my wheelchair so much when I'm cruising around the neighborhood! Thanx

                    I also didn't know you could switch out your wheels between your handcycle and wheelchair, that's pretty awesome!

                        Nice job, Brian.

                        I highly recommend people try this or some other way to take your wheelchair with with you when you handcycle. It is awesome. I am towing mine now and commute 3-4 days a week to work. Love it. Attached is a pic.

                          No, your chair wheels should be fine. I go down hills at 15+mph in my chair sometimes without issue.
                          The handcycle accepting standard quick release axles is a feature that was specific to my model of bike. I don't think they make them like that anymore.

                          You mean like My395 does? For several reasons.
                          1. Rear wheels of the handcycle aren't wide enough for the chair wheels to fit between them. If I attached the footrest directly to the rear bike axle the bike wheels would rub on the chair wheels.
                          2. Because my bike doesn't have the bumper bar behind the wheels like My395's bike does, I'd have to fabricate some sort of extension bar to attach the chair. Pulling the chair with a soft connection like a rope would be a disaster.
                          3. Your lawn mower has a motor in it so you can't feel the chair dragging behind you. I guarantee you that towing the chair requires more energy than clamping it on like I do. (also see #4)
                          4. See how My395's chair is tilted up at an angle? That means the camber of his rear chair wheels is working against him. It's causing more drag and wearing out the rubber.
                          5. I don't want to be that long. I have a poor turning radius already and adding more length would make a 3-point turn even more cumbersome.

                          Don't worry about my response to Baldfatdad. However you make it work is great. If I had that rear bumper thing I'd probably do it exactly like you.
                          I agree about its awesomeness. I can't believe I've had the bike for 20 years and not done this. I would have had thousands more miles on it if I figured out a system earlier.
                          How long is your commute?

                            I have a freedom ryder a quickie mach2 and an attachment that turns my wheelchair into a hand cycle. Got the attachment in 1993 and have put tens of thousands of miles on it and wheelchairs and have never had a problem. Have had it up to 35mph,going down hill, and no problems I use the attachment every day go over 20mph on it every day and no problems. The first chair I got I used for about 14 years and am on my second chair and have been using that chair since 2004

                              when you do an image search on google for DW Drums MG-1 clamp a pic of your handcycle is the very first image that comes up...
