Very inspirational. Last comments were over a year ago, but this deserves to be seen by anyone with a disability. I am wheelchair bound and live next to the ocean. Slowly building up parts to make a beach accessible electric wheelchair for myself using an old wheelchair frame I had. Going onto the beach is why I moved here and I have to adapt a tad to be able to do so. Like so many others I am disgusted with the price of anything having to do with disabilities. Looking for an off-road electric wheelchair and the ones that boast being affordable are asking over 5k. That is around 4k more than I have to spend on a chair. Only issue I am running into at the moment is how expensive the raw parts are. I have about 75% of the parts I need and had spent around 600.00 USD so far… and that was trying my best to be fragile. I still need a few more Fat Tires and rims and those are not cheap. Thank you again for posting this.
Firstly my good man, don't ever apologise for a wonderful Yorkshire accent! Most of my wife's family are from Hull! And secondly, THANK YOU, THANK YOU, THANK YOU, for recognising that us mere mortals cannot afford these things! I'm currently looking into funding for a Grit Freedom Chair, which is a very similar thing to what you've designed and built for yourself. I say 'looking into', because I know full well that I won't be able to get the funding to be able to afford this thing. Firstly, it's manufactured in America (the first hurdle I've got to negotiate), secondly, as you've rightly pointed out, these things cost an absolute arm and a leg, (it works out at nearly 5 grand for goodness sake!) and thirdly, at least 90% of the funding available for these things is aimed at kids, or least for people under the age of 25! I'm a 48 year old man, for goodness sake, what chance have I got! I want to enjoy what life I've got left, I want to go off the beaten track a bit. So I need something like this! But I can't afford it. I wish the manufacturers of these things, would get it into their skulls that the very people that need these things, are also the poorest people in our societies, the disabled people who, generally speaking are on benefits! I guess what I'm trying to say, is congratulations for taking matters into your own hands, and actually building one of these things yourself, and getting yourself out of the predicament that many of us find ourselves in.
This is outstanding !! I love the simplicity of the design 👍 That axle weld is going to be very highly stressed though. It needs a 10 x 10cm plate for reinforcement.
Thank you. I've been looking at expensive adaptations for my 10 year old sons wheelchair and I honestly can't understand why things to improve a child's quality of life cost so much, it's outrageous. Now I feel competent enough to build him a chair he can use in general life.
Thanks I hope the video is of some use to you. Thing is to try, and see what you end up with. I do all my planning in my head and then it just seems to come together. I am just going through it all again with my MKII version but it has turned out to be very engineering intensive and even landed me in A&E at one point. Almost there now though just in time for summer again.
Thanks for posting your work, every wheelchair user that has read of any chair ever invented, and put to market, has said the same as you! The first being that the expense is usually out of reach of someone in a chair and the second thing I found, was that the best ideas rarely come to fruition, or are usually only made or sold in countries like the US or China LOL! I have a few older bikes and 4 wheelchairs here that I could and should use as the basis for making a chair with a lever drive, that can get me up and down the hilly terrain we have here, without doing more damage to my shoulders! Cheers!
I just wanted to see what I could build, I had tried to go on grass on my expensive lightweight alloy wheelchair and it simply didn't. I bought a cheap standard wheelchair from Gumtree and cut it down. Then one night I took the back off altogether and sat on it backwards. I managed to get out of my drive and up the curb at the other side of the road but it was all over the place with every push. It is my first attempt really. I have not monetised the video at all and there should be no adverts watching it. I just put it out there to try and help others. I am very surprised that no one has said"Well lets see what it can do!" But that will be for my next project now.
Omg!!!! Genius!!.. we just got back from a trip to a place not so wheelchair friendly and we're thinking of a way to build one that I can use up there next time and something like this would be perfect so I could push myself around that ground!.. thank you for the idea!
Thanks, already building a more improved version. Just got a BMX bike with 20" mag wheels so I can use one for the rear wheel.Dragged a 4" log about a forest the other day with that smaller 12" rear :) May end up with a slightly longer wheelbase but will put a caster on the front so I can tip onto that should I need to get through doorways or into a lift.
Amazing work - thank you very much for taking the time to share the process and specs with us. I'm in a similar boat to you and many people commenting in that the all terrain chairs available commercially are way out of my price range (given limited disability income), and this could be a life changing innovation. If you're around this channel & still answering questions at all, might I ask why you chose to put the wheel on the back rather than the front? A lot of designs I've seen place the third (child bike) wheel on the front, and leave a back wheel off completely, which cuts down on length and theoretically makes it a little more portable. Your thoughts?
Climbing curbs and going up slopes. If you have a small wheel at the front you have to put half the weight on it. You have to wheelie it up a curb then there is nothing to stop you from tipping out backwards. With the two big wheels at the front you can easily "climb" up and over things with a the rear wheel for stability.
i like it , its similar to Trekinetic - All Terrain (you can see that to get more idea), please update us with this as its looks so good and so cheap. please make a full video .love to hear from you soon. will be waiting for the updated video
Nice but needs some gusset plates or triangulation IMO, there is a lot of leverage on that square section tube. I'm V interested in how it lasts as my son is in a chair.
Hey Shawn, I was watching at your video and I think it is a great design. I have a disability and I am looking to make my own Diy wheelchair, I already made 3 versions of it but I like the simpicity of your design, do you mind if I use some of your design ideas for myself? Thanks!
I like the idea of this very much! I'm surprised you call it heavy at 18kg...my standard wheelchair I bought secondhand here in France comes in at 23 kg. Itld be great to see some footage of you using this too! I'm looking really for an electric wheelchair solution now as I'm starting to have trouble with my hands now.
Development stopped when a hacksaw injury sent me to hospital. I then modified a standard wheelchair for off road use. I got really proficient at wheelies😁👍
@@shawng5799 Well done! I'm not very good at wheelies. I may need to get some sort of electric wheelchair soon. I have a progressive neuromuscular problem.
Nice work, I wonder if the small wheel was at an angle wouldn’t that help the wheel stay straight. The front fork on a bike is at an angle that helps keep the wheel straight, shove a bike & let it go & it will correct itself & stay upright.
You are brilliant. Inspiring too. I have MS and I know the day I'll need one is coming. I'm looking for ideas, I spotted the office chair, do you do this kind of thing for work? Thank you
fantastic build. I have been looking at building my own chair since my mobility went down hill but after seeing this I realise I have been over thinking all aspects. I will be knocking this up ready for the summer holidays as the kids love playing in the woods at the bottom of the garden but no chance getting a normal chair down there! just a thought: if the rear forks had been welded at a 45 degree angle or so that the box steel and fork where welded at 90 giving the wheel an angle whilst seated, would it not provide an easier time keeping it all straight and not swinging out beneath you?
Only just seen the bit about the angle of the wheel,sorry about that.I found that if the forks are not upright the wheel is super hard to turn. You can try it yourself first holding a chair castor in your hand and moving it about. I did :) Also if it is not straight up and you do get it to turn you can feel the back end rise up and fall. This does happen if you get the two front wheels up a curb leaving the rear behind you can fell it doing all manor of strange things.Including flipping sideways against the curb stopping you from getting up :(
I like your thinking and concept .I am just starting a wheelchair convertion for my diasbled wife so she will be able to go on the local beach .I am no engineer far from it , And yes it is nearly a crime for what fork's charge to buy beach wheelchair's and I don't know How they can charge nearly £600 for a convertion wheelchair kit so it can go on the beach . it is because of this and the fact there are many disabled people who are missing out of not being able to enjoy going on a beach including my wife that I have taken on this Project .keep up the good work . Ps when are you going to add a electric motor to you new designed wheel chair .
Sorry for the delay in replying. Due to a workshop accident all work is currently stopped on that wheelchair. You mention electrification of it, funnily enough I have just bought a kugoo M4 electric scooter that I am trying to pass off as a mobility scooter with the vehicle registration department.🤫 Does 29mph😈
Shawn G I hope you're still monitoring this post. I have a couple of questions. If it's not too personal a question, how much do you weigh? I weigh about 235 lbs (107Kg, 16.8 stone). Do you think this will support me? Would it be better to have the axle tube be mounted underneath the longitude tube instead of on top? Do you think it would be possible/feasible for the wheels to be easily removable and the lateral(axle) tube and the long tube to pivot to facilitate storage? Thank you for sharing a truly inspired and inspiring design.
I weigh 85kg about 190lbs. and the other things you have asked about I am currently carrying out on my MK2 version. Just go for a bigger steel section if you want to be sure about its weight carrying capability. I used what I already had it my garage. HTH
Thanks! I only have about two days worth of work left to carry out on the MKII version. I could get it finished next week but it is so cold now I wouldn't be able to spray paint it. So I have done all that I want to until it gets warmer. Its got a new bigger rear wheel 20" and a seat from and exercise bike so it is much stronger and packs up smaller and may even be lighter. Will do some off road videos with it when I get it done.
shawn G I look forward to seeing that one. I like going to Volkswagen shows but as then he always Outdoors in a field the only one I can go to now is the VolksWorld show which is an indoor show. I may need to copy the Mark II.
Thanks! Really pleased how the MKII is coming along though I have had to slow down with it since a really bad cut with a hacksaw two weeks ago landed me in A&E :(
so you think you could roll the chair with just the tires and not need the push ring? I can still walk but but not much without my legs hurting like hell. I think I would like wheels on the front like a normal wheelchair like the one you have on the back.
Could I get more information from you about the hub conversion from wheelchair to mountain bike wheels? I am in the process of rebuilding my folding chair with bigger front wheels and a back out-rigger that folds flat. Moving the wheel mounts just to the front of my center line sitting in the chair for better torque and stability.
I'll do my best what do you want to know? I counted the spokes and paired the two up. Watched an Australian woman on here lace up a BMX wheel and Bob's your Uncle 😉
@@shawng5799 It has been a long time since I opened a bike wheel and I've never been in the wheelchair hub. My concern is if the axle and bearings have to be completely replaced, or will the bike tire bearings accept the same size axle as the wheelchair. I don't have a bike your tire yet as I'm in the planning phase still so I can't do a physical comparison.
@@kellyspeakes8350 I bought two quick release hubs with spindles from ebay and then put them into the bike wheels by undoing all the bike spokes. I did not touch any bearings. I used a battery drill set at minimum torque to tighten the wheel back up and kept going around the wheel increasing the torque setting, it worked really well for me. I then fitted the wheels and spun them and tuned the wobble out.
Having only 3 wheels it does not get any torque. If it had 4 then it would, but if you lift one wheel on this, it lifts the wheel nothing gets twisted. ;)
Yeah I know I'm having the same problem with chairs are so expensive so I decide to make my own I met him one that goes 10 miles per hour then I'm making a second one that could 45 50 miles per hour that is controlled by a video game controller
If you look at my other video you will see what happened with this project. The version here worked fine though I wanted a bigger back wheel so it would handle kerbs better. I fitted a new stem and a 20" BMX wheel but I could not get it to work as the angles were all wrong. While modifying it further an accident with a hacksaw landed me in hospital and my wife banned me from the garage. Then I came across an expensive wheelchair for just £100 and within two days I had resprayed it,re-upholstered it and fitted BMX tyres. So the project has not been touched for almost a year. It is strange as I woke this morning I had just thought about a modification I could try and then I read your comment. So watch this space this summer.
Awesome job. I am passing this on to my son. He is a tinkerer and has wheelchairs, maybe he can get some ideas from your build. God bless ya.

Awesome, all it needs for me is an engine. No grip.

Cost efficient
Not sure about the structural integrity. I fear it my torque itself to pieces on really rough terrain. Please take care.
