- In this video we will be starting our 3 wheel drive motorcycle with rear steer project, this thing is crazy!
if you liked this video check out last weeks video we built a duct tape boat.

We made new merch!

Thank you for all the ideas on how to steer this machine!! We definitely need your help figuring out how to make this drive around:) We had a lot of fun with this one and can’t wait to continue with this build
I think you can lean it w(motorcycle tires :)
Interesting build
You can have a gear on the steering bar, mated to a gear on the top of a shaft going through a cylinder with bearings on either end that gets attached to your frame (maybe the steering column from a sacrificial pedal bike). At the bottom of the shaft, you can attach a chain gear and run a chain and attach it to both sides of the rear tire frame using guide gears to keep the chain inline with the frame.
Why did you leave grind hard? Don't get me wrong I love that you are able to do your own thing but grind hard definitely lost a lot when you left. No disrespect.
@@danielmcallister5892 I have a video on that:) short answer it was an hour and a half drive both ways and I wanted to do more street orientated vehicles I’m young and I want to experience life
Your fundamental misunderstanding of physics, friction and geometry gives me anxiety.
I honestly had more faith in BUM until this video came out. I thought i was being trolled until i realized it's not a joke. now I'm yelling at the screen lol
The Bums are about to learn about physics. Exciting stuff.
@@mrdabeetle1 😂
I wouldn't count on that happening for a few more builds
Of course it would be Will's brain to come up with the inline skate version of a bike
😂
Some drank some Haytorrrrray😂
Recall the GHPC monster chopper, you/they learned the importance of rounded tires for turning. Inline tires (motorcycles, bikes, etc.) rely on rounded tires and lean to steer. You can't do it with flat tires. If you switch all 4 to rounded tires it would work better, but there would still be a lot of scrubbing in the front 3. For smooth steering with no scrubbing all the contact patches need to be able to land on an arc. 2 wheels always land on an arc, so only one needs to steer, which is why this has worked so well for bikes of all kinds for centuries. For 3 or more inline wheels to land on an arc you need ALL of them to have steering.
Id say make it 4 wheel drive & kingpin the center so the frame between the front & rear 2 wheels will pivot for steering,then an engine on each 2 wheel frame section!!
Good idea.
@@brijidoolaldejr5365 this is a fantastic idea
@@Bummotorsport You would probably still run into problems driving multiple wheels without any sort of diff, right? Maybe just drive the front and rear wheel?
Yeah, I don't see that thing turning much at all.... good luck, but I think you need to rethink your steering solution.
I think we are going to put steering in the front as well so the steering moves both wheels like a cyber truck or a Subaru xt
I think your fixed tires in the middle are going to give you to much resistance and want to skid even if you steer front and back
@@KeithWE27 rue - plus, with the current steering setup, you wouldn't be able to lean in the corners either.
Ik I'm crazy but twin rail frame, all wheel steer!
He really misses the Solo!!
You're gunna need 3 of those wheels to steer getting that geometry right is going to be crazy! Cant wait to see what you come up with.
My dudes, I use to own a 6x6 5 ton truck. When I engauged the front axel drive, you can't really turn it any more, that's just for going straight. Because the front wheels were drive wheels are on the steering axel, if you turn the wheels while going forward, both rear axels are pushing forwards -and the front axel is pulling at some angle so they're fighting eachother. I like the idea what you're doing, but I think the middle wheels will have to be able to swivel, so they kind of act like casters. That way when you are turning, you're not pulling the middle wheels sideways. Just food for thought. Best of luck to you, can't wait to see this project through to completition!!
Look at you boys go! Gettin' real fab tools, lights in the shop and every damn thing! Great start, gang!
You are officially one of my channels I watch so, good on ya!!
A grinder and paint, makes you the welder you ain't.
Haha love this 😂
Im gonna just say the first thing that came to my mind " This is Premium." I love your new channel. Keep up the amazing content. 👍👍🤘🤘☝️☝️🤜🤜👏👏👍👍
Ethan is laughing and facepalming so hard now. looking forward to you trying to steer this bike. :D
Use 2 cables push and pull in a x shape to reverse the front steering
that premise is wild
You may need to make all the tires turn. If not, the front straight tires will overpower the machine to go straight. Maybe make front tires turn slightly then back turn more. Remember forklifts only max out at about 13 mph. Because they are super sketchy at higher speeds.
here's an idea for a build, a drift kart, it has steering in the front and back, but you can control the front separately from the back and the other way around, but it's front wheel drive, i made one, it's pretty cool
This project looks really fun!!! I don't think it will work, but it looks like a fun project!! hahaha
you are going to need to turn the human around in this bike. Im pretty sure that the leaning to keep balance is going to be impossible. Plus.... how are you going to lean on camry tires?
Remember that unit bearings need to have a stub axles in them so the dont fall apart. May not matter in this case because how small the machine will be . Just giving a heads up. Otherwise have fun.
Maybe try to set up the steering with a lever setup like a zero turn mower? That may be easier to put together as a test run just so you can see if it will even steer before pulling out a differential and everything lol.
That pipe bender is a huge get, that chassis looks so clean. Can't wait to see all the sick karts and bikes you'll be able to make with that.
Original idea! Glad to see that you have a bender and a notcher. Good luck with the fabrication!
I'm stoked with my OG BUM shirt guys. I wasn't expecting the autograph an numbers...but i did somehow get shirt #68...the year I was born.😊
best video I've ever seen
Turn the seat round and make the front the back then driive in straight lines 😁 . Great project, great show, thank you
Good to see the shop get some new tool's! I can't quite picture this build yet like where is the engine going to go? But definitely looking forward to see how it comes out.
👍🏼👍🏼
Bum history 2nd half build it sure is the 1st time. This is going to be soo good
You do use cables to steer and run them down the frame and they cross on the rear section to make it steer correctly
The 2 middle wheels need to be on trailing casters (like pivoting supermarket trolley wheels) so they are free to follow the lead.
I was literally just watching the last few months on grind hard and thought to myself “will is getting the hang of making stuff and is such a character… he’s like becoming the core of the channel… he should make his own channel” and here we are
4 wheel drive and 4 wheel steer would be interesting. The outer two tires, if steering opposite of each other would need to turn approximately twice as much as the inner two tires. If all 4 turn the same direction they would all steer the same angle. But if it was 4 wheel drive it would climb ... well ... interestingly.
If you give the first wheel the ability to turn opposite of the drive wheel it would help with control and stability
I'm surprised only 55k ppl subbed so far. I figured _everyone_ would feel the void of missing weird Will builds.
I mean quite honestly, I love Will's enthusiasm, but on his own this channel is basically GHCP ordered on Wish. It just lacks skill and experience.
@@AccAkut1987 Yea, he would be better off just stop building stuff and start making videos about something else.
@@AccAkut1987 gotta start somewhere.
I'm glad someone has ideas on how to steer it, because I can't see how it would work as is.
that someone clearly isn't anyone building that thing.
Interesting idea. Carry on.
Hydraulic boat steering would make it a lot easier to steer and easy to buy just about anywhere
Thats going to be crazy once its done
The proportions and seating position reminds me of the FAB1 from thunderbirds.
Good choice on the DJI Mic 2. Super clean! I would suggest getting some nice chains and clipping the mics to the chains then it would look amd sound sick
sitting on the back it kinda looks like a massive chainsaw, that might have to be the name for this project
Love these builds. Keep doing your thing man!
@@tylerhunt7552 thank you!
Fair play to listening to your viewers. Massove difference from the last video!
Keep it up Will!
@@weldingbad thanks!
I think you guys should do one motor per wheel. If you had 2 bars on either side you could pull right, push left and the rear would be reversed.
Round diameter tires are going to help. I know its going to be fun and vote yeson the pop up light
So much better content! Thanks for bringing fabricator Willie out again! Also nice to see Taylor actually has a personality lol.
Maybe try steering from a boat or hydro?
Ive already seen someone make a 2 wheel drive 4 wheel motorcycle. This though is gonna be even crazier because its much bigger.
Hey Will! Love the channel!
One thing though, you need to work on getting the audio levels a bit more consistent. The music seems to just slam in after people are speaking real softly.
Love what ur doin though!
Thanks for the input haha the audio is something I struggle with I’m still learning to edit but hopefully soon I can dial in the levels
even worse with headphones on
I think of you could make some caster with the steering geometry so the rear end lifts up a little when you turn, taking pressure off the center wheels.
Cable steering. hook the left side of the tire to the right side of the bars and vice versa
Pretty cool that Rogue Fab are helping you boys out. Onwards! 💪💪
I really want this to work but i dont think it will lol good luck guys
If it doesn't work out, you could make another three wheel set and build a platform in the middle and have a high ground clearance trailer
make the chang li great again
Have you seen how wheel loaders steer? Their wheels are fixed and the chassis has a joint in the middle where it pivots to steer, that could be an idea for your build
Premium . ❤the content.
The rear wheel will _not_ turn the bike with those three wheels in front of it like that. It _might_ work if you have three skinny motorcycle tires on the front wheels and a big fat truck tire on the rear wheel and the rear wheel also was the only drive wheel, but you'd still need some funky pivoting joints in the frame so it could lean into a turn.
Where in bums timeline are they gonna build a space ship? Space x better watch out 😜😂
Here's how I imagine this project was conceived: "These snow tires are always in the way all summer long. I wonder if there's something better to do with them..."
how did you think of making it? why did you think it was a good idea? also it's really cool!
Look into a John deer Amt sxs. They have the geared steering you are looking for and also use 2 rear axles and I think they have different sizes tires so that it turns correct
Great watch, as usual! My only complaint is the audio mixing, it was all over the place, I had to EQ it every time it switched between talking and music. You didn't have this problem in any of the other videos as far as I can tell, so it felt weird for it to appear now ^^
Wil don't give up you can show them where you used to work you can do it bro,.
Many things come to mind, but the first is called tire scrub. As someone who hauls trailers with multiple axles tire scrub is very real. I don't think this will turn before it leans to hard and the rider falls off. These are only thoughts. I look forward to being wrong.
I should have known from your time at Grind Hard that your own channel would be even swindlier, but I wasn't quite expecting this level of jank. I love it lmao
wait... Arr and Dee? What is this? Am I lost?
Fellas, that thing will not turn unless you put the triple tree on top of the wheel. If it's in front or behind the tire, when you try to turn, the tire itself is gonna make it incredibly difficult to turn because of the grip/friction it has with the ground since you're trying to force the whole tire to slide out of its own path rather than just rotating the center at the bottom (center of your contact patch). Even if you're strong enough to get it to turn, it's gonna end in a crash.
Also, the rear steer is going to either A) turn it into a 2 wheeled motorcycle when you lean into a turn, B) make turning dangerous because of the risk of hitting a bump on one of your middle tires (would probably bounce or change your direction mid turn), or C) if you stay upright during turns at speed you'll just fly off and lay it over.
I'm not a physicist, but from riding for a while and having a basic understanding of why every part in a motorcycle is the way it is from my mechanic courses, these two areas put out a huge red flag for me.
Another issue is that you will need suspension. Without it, any slight bump will bounce the whole bike and cause safety risks, and also cause for a super uncomfortable ride.
I would make the front one steer with the back one to make it easier but let’s see what you guys come up with
If you need to make it turn easier then you can probably drop the center wheel by like half an inch. Make it a drop center ya know.
I'm suprized u guys even tried welding cast iron, it's not easy and does not always hold
Yeah the steering is going to be a little difficult what if you use the two front wheels like a normal motorcycle for the most part and the remaining two wheels like an actual caterpillar that pivot you could even add more wheels in the back so they would just follow behind in order for the most part and put maybe seats or something on them with even hydraulic or some kind of spring system to keep tension on the wheels when you turn but then it would be more like a little caterpillar or scorpion would Flex so if you drove in circles you could basically play Snake
Sound is good this time ! Good Job ! Thanks for listening 👍😀(Music is still all little bit to loud)
We will fix that next video thanks for the input:)
For steering why not use a lever system with push/pull methods? Like you turn the wheel and it uses a push rod that goes both front and back but the back one is connected to a lever that changes the direction of force?
Just a thought, no matter what you end up doing I'm excited to see where it goes!
Can't wait to see this finished!!
I think it's awesome. What if you make it like a duly in the rear to stabilize steering. ? Idk love the videos . I think you will find something. interesting.
It reminds me of those low Python recumbent bikes.
my kind of craziness
I'd look at going center pivot, 2 in front, 2 in rear, pivot in the center.
That's the human centipede prototype. 1of1
9:01 zyn for the win! 😂
I love that this is just wills brain going wild and building whatever he wants with subaru parts 😂
Nice shot with the garage door 😃
Bender will be a game changer!
Maybe a 2*2 steering, so a mono frame, with the first 2 wheels turing the way you turn with the last 2 turning opposite
It might be easier to turn if you move the steering wheel pivot point to the center of the back wheel
Taylor looks like a small less energetic version of cleetus mcfarland but I love how he's just super calm about everything
This would be perfect for ice fishing if you studded the tire's
the steering pivot will have to be moved to the centerline of the steered wheel
wheel 1 steer direction you wanna go, middle stays solid, third wheel steer opposite. then last wheel make it into 2 wheels... like a trike backend trailer?
It's like human centipede, but with camry wheels.
That thing looks sick!💜
Put the pivot for steering above the wheel or else your steering tire is going to swing instead of pivot.
Amazing content WILL WILL WILL
Hey come on guys lets get this built.i also think you shoud make the 3 wheels steer and be powerd
i want to build something with you guys lol ill bring my supercharged mobility scooter for yinz to ride!
Yo where are you located I really want to see the scoot
@@Bummotorsport Im about 20 minutes outside of Pittsburgh, Pa. its terrifying hahahaha im trying to finish up the test drive video right meow but I have a few vidoes up of the build. Its right up your guys alley
I love what your doing!
You're
I'm sorry 😂
Get some stickers made up! Would definitely throw a couple on my tool box
Keep up the great work man. 👍
Either make it steer in the centre or make the front and black steer other wise it won’t steer at all
Reverse steering works if you lean
