I have been in a wheelchair for 16 years. This summer we took the kids through national parks. I had to hang back while they went for hikes on trails. This would not have enabled me to go anywhere, but I could have done a lot more than what I did. Love the creative spirit and ingenuity. You guys rock.

Lower the tire pressure on the back wheels for more traction and for a softer ride, also rig the brakes so one brake lever controls both back wheels and another for the front wheels ;)

@@jeanmartin963 I’m building a catamaraned twin fat bike similar to this right now, but pedal drive. It’s trickier.

My only suggestion would be to remove the clips that hold the saddle posts and either cut down those pieces of the bike frames or cover them up with a soft material so she wouldn't accidentally hurt herself when getting in and out of it. Cutting them would be the most aesthetically pleasing, but covering them up with a soft material would allow to convert them back to stock if you were to upgrade the frames to have rear suspension later on. Cheers and congrats on the great and lovely gift you made for her!

That is a great idea! And its even greater that you posted the steps for anyone who needs it to replicated it!

60-80% of braking comes from the front wheels. You're skidding around because you disabled the front brake. One armed riders will splice the hydraulic line to run both the front and the rear for better stopping power and even braking. Overall, making the bike more playful and safe. You may have disabled it, not wanting any riders to "jump forward", but if you turn and brake with only the back wheels you're likely to skid and fall to the side anyway. The lever allows modulation of the pads so reconnecting the fronts will make it a lot more enjoyable. - Pro Mountain Bike Rider & Bike Mechanic.

Super-cool, will be awesome to see this in production some day.

You absolutely need to lower tire pression. This kind of tire are built to work well at a very low pression in order to improve traction. Also, be sure to use it tubeless.

Wow jerry you did an amazing job building this gorgeous beast for a good cause

Thank you for this man this is freaken amazing

Good job young man !

For offroading you might have to add some kind of suspension in the back, so that there is no tire lifting of the ground.

Great Rig!

Holy wow that looks fun!

its a great project, i hope you do a follow up video about went you make an improvement to its design to make sitting on it easier.

To get more traction lower the tire pressure on all the tires so they can form to the ground better, fat bikes are designed for lower presser in general as the tires are less likely to "fold". Also with a lower tire pressure, it will add a boatload of suspension! I'm guessing anywhere from 15 to 20 psi but test around.

Karl why lower front tyre pressure, all that’ll do is add rolling resistance, but for the rear wheels I completely agree

@karlsven

@@4wdsome444 That's a good point, with there being 4 wheels you don't need extra traction in the front to keep the wheel from sliding out from under you. But I wounder if it would affect the suspension, with the center of gravity so far back maybe not!

For more off road traction, you can drop the tire pressure a little to get a bigger contact footprint but sacrifice range.

This is awesome!!!!! The other suggestions I made are strictly for consideration to add to the next version, Model B. What you have done here is incredible and the type of inventiveness that really needs to be encouraged.

You guys are brilliant, defo to front brakes, i think vertical bars coming out of each seat post up to the top and bent forward to provide a shelter above for the rain and from breaks yes possibly also lean both bikes in towards each other just a little bit like the wheels are on a speed wheelchair also you can put motors in front wheels also the barscoming out of the seat posts can also be a roll bar for safety.

Wow 😮Loving all these videos

"...should still be legal" XD love your work mate, keep it up

Very clever design. Opens up a whole new world for the user. Would be interesting to see a rear drive track system with a rubber track and bogey wheels similar to some small excavators. Traction seems to be the only drawback on some more extreme trails. Greater surface area of a track that thing would probably climb those extreme hills like a mountain goat.

Amazing sack. Great job.

Great work! It looks sick! For the next version, make it four wheel drive, and get rear shocks.

I have hiked that canyon, i always thought you were alot further north of there, did not know you are in the same city as myself. That is just cool.

This is pretty awesome. I have a small recommendation: fenders / mud guards - so water from the ground doesn't splash onto her. Great job!!!

As you mentioned in the previous video, a full suspension frame would be superb. it would definitely help traction when one of the back wheels comes off the ground, and give the bike a more suitable "crawler" feel. Another thing you can look into in the future, if you ever make another wheelchair bike, is a mid drive motor. Maybe an after market battery. DIY ebike components are much more capable. Higher efficiency and higher torque.

Meatier tire and your set! Great job!

Here's a nice team, Zack and his brother Spencer! This could be a new and great format just the two of you doing all kinds of projects and tests together 😉. You got my sub on your *younger* channel also 👍.

Hey Zack. Awesome build,,,, I would suggest lowering the tire pressure as mentioned by Aram Teran. As a full time E-FAT-bike Rider I can vouch that lowering the tire pressure works wonders for grip and over all ride comfort I have my tires running @10 psi rear and 5 psi front for off road and on road I go up a bit to cut down on rolling friction, OVERALL GREAT build, with all the negativity surrounding ebikes this is something great that you have done.......

Great project.

Love it! in a dream world, I'd Add two "rear wheels with electric hubs" to the front as well... AWD. Then split the controller for each side so it could turn on axis, or give the option to lock it out and crawl up the hills :). would an "suspension seat" like in a off road buggy be the answer with the current frame design? Possibly lower the pan in the current design to accommodate for the seat travel. I liked the other's in saying using hydraulic brakes. You could even make hard lines like in a car and possibly repurpose the safety valves and crossovers for the safety aspect if pressure was lost. Ha. I could go on and on! Just found your channel. Thanks for taking the time to do these!

Heyo, for front brakes, you could run hydraulic or mechanical brake lines through the steer tubes of the forks if you have nothing obstructing. If you do have a star nut in there, you might need to get a special one to route cables through. That'll allow you to mount brakes without concern for cable wrapping.

Hey Zach, as a mountain biker and I live in Utah somoe of my friends have a plus size tire bike so with wider tread and for the tires i would recommend Maxxis Rekon tires or Maxxis High Roller II plus tires. You can order them online or at a local bike shop

Tie brakes together add hub motors to front for 4 wheel drive situations good work guys

Great work. I think you need triangular suspension. If you connect the two bikes and the seat at the crank the bikes can move around this point like when you stand up on your bike in rough terrain.

Looks fun

Omg ❤ I have a teammate that worked for railroad company and ending losing his legs and we was looking for a way and this really would have him wow. This my first time seeing this video ❤❤❤❤

I am blown away by the work you done here! I was just thinking about the stability of the wheelchair... Could you attatch both bikes in a (maybe) 20° angle to the seat? I'm not sure how much it would affect steering or the turning radius, but it would give the construction more stability. Maybe play arround with the angle a bit. Or maybe add a grid (like a lawn mower height adjustment system) on both sides of the chair to adjust few different angles for different tarrains. To keep it stable maybe use two pins on the grid. awesome work :D

I don't know about US but here in Finland wr have Tempur wheelchair cushions. Tempur was originally created for Nasa as seat cushion and one of the original scientist creating the material has said "I was trying to develop seating for aerospace vehicles so people could better survive any crashes or impacts." If you have those Tempur wheelchair cushions in America I'd suggest to give it a try.

Really great work!!!!!! Im also a wheelchair user and desperately wanna that wheelchair bike 😍 but i can't have i know...

Hi Zack, Four ideas, 1) Move both batteries to under the seat, and 2) Cut the upper crossbar off the left bike, this will lower the center of gravity and allow side entry/exit. 3) Put some type of armrests/guards in the old seat post holes. 4) Add a second link behind the fork to stiffen the steering while taking some load off the angle brackets.

@terrenced.1586

Brian Hanson great ideas, but honestly he’d be better off just designing a custom frame instead of using two prebuilt frames, build price would also be drastically reduced.

Zack can get the bikes to move independently in the vertical plane so when your traversing very uneven ground the two bikes move to give ground contact on all 4 wheels. Will need design changes to the coupling between the bikes and also your steering linkage. As suggested by others a crawler gear upon this would be awesome.

Your brother looks like he gave it a good run👌😍😍😍🇦🇺

Nice! I could use something like that ...well not me , but my brother who needs a wheelchair, but he can't use a wheelchair by himself, so for whoever is pushing his wheelchair ( hard to do uphill or off road since he's not light ) a side by side two seater would be awesome

You should put the original cycle seats back so that both you and your brother can ride along(by sitting sideways). I know that it is pretty stupid but it would be really cool.

I would have preferred the handle bar being in the middle like the regular bicycle with an option of adjusting it like modern car steering wheels lower or higer or near or further depending upon the reach.

Cool bike

Great job! A 350W hub motor on each wheel, a wider stance, and a belly pan/bumper to protect the rider's feet and it would be a hoot for non-mobility-challenged too! A clever fold could allow it still fit in a pickup.

I want one! Because it's hard being crippled & going outdoors!

I would add a set of the rear shocks from some other bike between the rear bottom of the seat and the frame to give some more shock absorption. basicly use the lower tube that had been for the pedals as a pivot point and then added shocks would make a much smoother ride

A really easy way to get extra grip would be swapping the rear tires for something like the Maxxis Mammoths. I run them on my bike and they do great in the snow, on gravel, and pretty much everything I can throw at them.

Fantastic! I know that's a wheelchair but this concept could become a great off-road quadricycle. Next time use bi-suspended bike frames, a roll bar plugged into the seats posts and connected with the pedals hole-bar and seat frame (for security and for to stiffen the whole structure), four hub-motors with a dedicated controller that can do reverse gear (and regenerative brake too), hydraulic brakes (one for two front wheels, one for rear wheels), parking brake, arm rests/rear fender and maybe lights ... I would like do it myself but i haven't money...

not only pedal, but if you look around bit more, you will find electrical as well, and some cases you can ride you'r wheelchair in

i have some suggestions for this thing, maybe like a revision 2 whenever you create the next bike? - bigger discs considering that the brakes looked like they barely worked. maybe up the size and go for 203mm on both the front and the back? - rear shocks. FOR SURE. - go for a nicer chair maybe? - work on the brake level positioning. maybe have them facing down instead of up? these things just all contribute to a better ride experience in general.

Reverse is simple, a switch that reverses the polarity from positive to negative can be located anywhere but you might consider rigging it to reduce the amount of power available when in reverse

You can always put lower pressure into the tires which can give you more grip

Puts lights on it! And a horn!

Zack, I need one for work. Lol. Quick suggestion thou, I think u should push the handles out more, like how a motorcycle handle is and then adjust the break handles, so it would be much easier to break.

I so want one!!!!

spencer had some pretty funny one liners in this ;)

It would be cool to create this setup with two e-road bikes with slick treads. You could make a serious speed machine!

User access looks like a bit of a problem - but super effort. Well done.

Try lowering the pressure on those rear tires... Fat bike tires are designed for extremly low pressures. Also putting the seat more further backwards will help with those traction losses

Amazing

Catapilar tracks the way to go

Suggestion. One possible point of failure is the steering linkage bar. Being flat, could bend and render the bike uncontrolable. You may want to use a tube (with less propensity to bending than a flat section) instead. Heck, Cambry could even slip a light aluminium tube over the bar and call it a day.

I'm thinking this would be better with two softtail trail bikes...It would probably give more traction on uneven surfaces. But really cool project! I'm sure Cambry will be happily using it frequently.

thats insane who would have thought of that :D ... You my friend can be the CEO of a future electric brand

Maybe lower the psi or bar in the tires when offroading for a tad better traction. What a beast of a bike! Wow!

need some downgearing option for moving through gravel (?) - how much power was left when you did the Y trail ? Too late in season but maybe the Timp Cave trail which is paved could get approved on a 1-off basis to test there - otherwise it's a firm no-wheels on the trail. That's a fantastic place with really awesome detail and views...

Haveing les air on the tires would help with the tracktion as well

I’m disabled but I can still stand long enough to get in and out of this. I’d definitely do a quick release on the steering tie rod or better if it’s possible to do under seat steering like a recumbent trike has. The steering tie rod mounts and rod should be made out of tubular or square stock steel, not flat metal because it can bend to easily. I’m dying to get one of these, I just can’t afford to buy two electric bikes. I realize that this is the prototype and you already have a new version from Utah Trikes using one of their 4 wheel recumbent platforms, but I do wish you’d sell that seat pan as a kit to connect two standard electric bikes. Included in the kit could be custom steering pipes that put the hands in the proper position, the dual pull brake levers, and arm rest pads that stick into the seat post tubes. I like how the seat pan kit allows the bikes to be separated and converted back to individual bikes again. Hub motors could be added to the front for true 4wd or front wheel hub motors mounted backwards so they act like reverse gear. Not sure the long term effect of spinning a hub motor backwards when not in use though.

Zack, The rotation of electric motors depends on the positive and negative connectors which mean you should be able to make a pretty simple switch for reversing the motor rotation by reversing the current sent to the positive and negative connectors. - if I'm not mistaken :-)

Electric bikes normally using brushless DC motors, which are using an ESC to generate an alternating current (like 3-phase electric power). It is not as easy to reverse these Motors by changing the polarity. If you have control over the control unit you can reprogram it, or you can change the connection of two of the three connection wires (ESC to motor) to reverse the rotation.

I have a design for the handle bars to make it more normal and it moves the linkage up while flipping the brake grips back to the fingers

A hub motor in each front wheel might really help in getting up hills. Basically 4wd. I’m building a recumbent pedal version on this. Maybe later I’ll make it electric.

Make a rear axle for the bike and have breaking system on the axle along with the drive system. I would also suggest installing a rear shock too. And try to incorporate front brakes somehow and she'd be mint. Well she already is mint but you could make that thing a monster! Great job on the build!

Cambry Twin Low range would help with hills.
