now switch the cog and chainring and we'll watch you fly to jupiter in just 3 pedal strokes

You’re about 10 years ahead of Sram and Shimano with this one.

Right idea, wrong frame. This needs to go on a Trike for stability. That would work well and you can add ballast.

5:42 This is the first time I’ve seen someone do a burnout on a bicycle and I’m impressed

I've been around Seth's channel for 4 years and this is the first time I've heard him laugh like a maniac with his creation and I'm loving it 😂😂

On a tandem, you’d have the weight and leverage to keep the wheels down, as well as extra pulling power.

Ok, so what would it take to make a tractorcycle practical? - Moving the mount higher would enable the bike to tip backwards under load instead of forwards, improving the traction of the rear tire. Keeping the mount where it is, will improve steering. Ideally a system will be available to move the mount around the center of mass for ideal control - Training wheels, a trike, or wider tires would provide zero-speed stability - A rigid tow line would enable the bike to provide braking as well as acceleration, but increases the risk of getting run over. - The drivetrain needs to be redesigned. If its structural components deform in a few hours of screwing around, it won't survive practical use. - Selectable gears would improve the range of speeds and loads a single tractorcycle can handle. IDK

id love to see how that rear gear would fair on a motorized bicycle

Kevin is worth his weight in gold. Never lose that man

guy with a 3:1 reduction: "this thing is gonna be geared like a tractor" tractor with 400:1 reduction: "you'll get there"

I have wanted to CNC a custom sprocket of this magnitude but never had the brass nuts to follow it thru. Thank you for answering a 30 year old question. Fun to watch you all do this, however painful and expensive to execute. Cheers!

3:46 when you were moving the wiimote & nunchuck too fast in wii sports resort in the bicicle game

That was the most terrifying "doing something little different but kinda the same" I have already heard

“Imagine a world where fitness is optional” My world….

Actually did this in our backyard quite a few times...cobbling bike parts together and reversing the gears. Dubbed the result "Slo-Ped bikes"...they were somewhat handy for pulling wooden carts (with bicycle wheels) that we'd load up with 250-300lbs of hay and haul to the barn. Traction obviously becomes the issue when you've only got a single drive wheel though ;-) First one or so we actually Dremeled out the inside of the large sprocket to fit the proper sprocket mounting on the wheel--but then we later just got lazy and stuck the gear into the wheel mounting (bypassing the ratchet) and had a "Johnny one-popper" where you could pedal the bike--slowly--with a single foot. Of course, this had the side effect of unscrewing the sprocket if you tried to slow the bike down with the pedals ;-). Good times.

One of the great videos I've seen. If you've never tried to tow or pull anything with a bike in your child hood (or adulthood), you have not lived. This is nostalgic beyond belief. Great fun video, thanks!

"This is pointless" Everyone who tries it giggles like a schoolchild. Nah mate, the point is it's a giggle. It's fun, who cares?

“Or you need a custom made bicycle that’s super long” seems like you got your next video right there :)

I want so see custom bike towing competitions. Really wild stuff getting made then doing some standard tests/competitions

I always wanted to do that. Thanks for it!!

"Hey I got my car stuck can you tow me out" "Yeah sure ill be right over" _Rides in on a bicycle_

Use a tandem, add slots to carry removable weights on the frame, training wheels, and use a crankset with a front derailleur to give yourself 2 or 3 speeds (one of which is even slower/higher torque than this one). Still not very useful, but way cooler (could actually do all the towing you tried to with this one).

I used to watch you a couple years ago when I was really into mountain biking, recently wanted to get back on the trails to get healthy and tried to find your channel again but I couldn’t! Low and behold, you show up on my recommended the next day!! Glad to find ya!

Im not sure why but ive been subscribed for a while now and this is the first time ive seen this. This gives me flashbacks as a kid when we hooked the wagon up to our bikes pulling them around.

imagine playing frisbee with that 😭

This is amazing! I really think this could be a thing, not the 74T but maybe a 50T with an electric motor. It could be used as a really good cargo bike. Im trying to make a bike that can pull a small boat

There are a lot of great comments on how to make it work better, we wanna see it Seth!

I love seths reaction to this

for a science project that a buddy of mine did years ago he took all the spokes on his front wheel and made the center offset, we called it the bounce bike. If you put your feet on the front pegs and pumped you could move forward and if you went too fast then it started to bounce the front really aggressively. Would love to see you try something like that for fun!

This is an old school Seth Bike Hacks video 👌🏻

I would love to see this done again but with training wheels on the bike and see how the results change!

Have seen a similar take on this which actually had a practical use and worked. A tricycle was used to reposition tool trailers. The nose weight of about 100kg provided the required traction.

I love how small Seth's bike looks when Pat is riding it.

Fatbike would give more grip when towing, and three rings in the front would make it (slightly) more useful for actual biking.

The murder machine! I thought this thing was long gone. Good to see it still bringing smiles.

This guy is a legend!

Put it on a trike. Preferably a fat tire trike for more traction. Maybe 20" wheels for an even lower gear ratio. With a delta trike you could put the tow line right to the rear axle and eliminate any tenancy for the front end to rise.

PI simplifies in the gear ratio calculation, no need :p

I absolutely love this Idea, but you HAVE to make a Part 2 with a 3 wheeled disability bike with 2 front tires. There are Cargo editions of those, that can hold ballast in the rear and front and ballance would be no problem any longer.

This is the greatest Seth Bike Hack's

Please find a tandem to try the cog on towing a load - a long bicycle with way more weight forwards of the axle to not going to wheelie! Also you then have an eccentric bottom bracket to tension the chain!

A bit of practical use: I have an old tourer that I use - among everything else - for towing a 15' canoe. Nothing as fancy as your setup, just a triple with a 22, a wide-range cassette, and huge slick tires. I simply strap a dolly onto the canoe, throw paddles and lightweight gear inside, pour the heavier stuff into lowrider front bags, hitch the end of the canoe to an adapter on the rear rack, and head out. I have a nice 15km stretch of whitewater nearby, with a put-in 45 km upstream from home. Last time I rode 15 km upstream with the canoe in tow, met up with friends headed the same way in a car, locked my bike, threw the canoe on the car, paddled the 15 km of whitewater with them, then paddled the remaining 15 km of flatwater, retrieved my bike, towed the canoe back home, unhitched it, and rode to a pub to brag about it. But what I really need is a folding tandem that would fit inside a 17' canoe.

Very good experience . Liked it

This looks like good for exercises!

Can we just take a minute to appreciate that Seth basically put a modified ocular saw blade on his bike as a rear gear

How light do you want it to be? *Seth: “YES”*

What if you swap them around?

I enjoyed watching 😊😊

i feel like theres a life quote about how the climbs can’t get any easier.

You really need to do this again as a trike with 20” rear wheels. That would be even more amazing!

Man.. I immediately sub, cuz I love this idea so much It's dumb yet so genius

thanks for this video i am in a proces of making a skider log Winch. this video is in perfect time for me to understand the mecaniks of geers sistem thanks a ton

The determination of that pup to get underfoot is astounding.

I need this. My 50T isn't low enough for going straight up downhill tracks.

That thing is wild!

you went about doing this the hard way. when i was younger i used to do a lot of hauling with my bike and built a designated tow rig. running a smaller tire size in the rear helped a lot. i found for most of the stuff i moved a 24" tire did pretty good but there was the odd occasion i would run a 20" tire but the biggest issue with the 20" tire was top speed was not very high even in the fastest gear. it did have tons of torque. i could easily pull my trailer with 400lbs on it up the steepest slopes in town.

Kevin sitting in the back like a little kid, and wearing his helmet cracked me up.

“It’s good for keks” - former Starcraft player identified.

this will be useful for quad cycle

Kinda want to see this stuck on a longtail cargo bike.. cool concept!!

Put the rear cog at the front and front in the back for high speed lol

One of my friends made a chainring as big as a 26" rim, and put it on his bike. That thing was literally not moving. We experimented with how much it can tow, and basically found out that you could bring a house down with it.

Thank you

We used to do this mod on old bikes just for fun and then ride with ease in the terrain, it always lead to the bearings in the wheel only lasting a short while after the mod...

Possibly your best video to date. You have to try this in Moab on slickrock. Or another trail that's super steep with tons of grip. It may just loop out but I'm so so curious now.

This video should be renamed to: Seth forgot that E-bikes exist so he took matters into his own hands.

This is beautiful

This is your best video.

I often climb steep mountains with a typical mountain bicycle, I would really appreciate this gear’s existence, some of you probably know how quickly you get tired in even the lowest gear lol

7:59 "And if you've been wondering what happens when you do this. Well now you do!" lmao

I can't watch this with the dog always being so close to the bike about to fall over 😂

I’d love to see this on a custom, 80lb, extra long frame with 36” wheels and an extra large bike trailer.

The “dinner plate” rear cog that could ACTUALLY be a dinner plate.

"how many torque you wanna produce with the ratio?" seth: hell yess

I’d love to see you’re reaction to stuntbike sprockets 😂 sick video 👏

crazy af ahahahaha loved it too much !

“Even if you want to theoretically plow a field with a bicycle, you’re probably better off just using an animal.”

When Seth posts a video is amazing, fun, and generally Sunday! Best day ever!

Bro y’all need training wheels just to stay up

That is hilarious! I always wondered whether you could even stay up with such a low gear.

I think Seth just invented a new sport “bicycle pulling”

I would recommend making stabilizers for the bike, as well as adding weights to the front and back of the bike. So like cast iron bars with weights hanging under the BB. This would be insanely awesome!

Ive done this with a kids bike from goodwill, it was fun

you had me at "from the creators of the shovel cannon"

0:53 makes me feel better knowing that things I learn in school actually can be useful 😂

Lovely, also kinda like the “old” Seth to do something like this. Love to see more like this.

Seth "Kevin your chariot awaits" 😂😂😂😂

I was always curious if it was possible to do so

Greatest thing I've seen on KZfaq in the last year hands down

It would be interesting to see how well this works with more than two wheels and a different centre of gravity - such as with a trike or even a recumbent bicycle.

I made a big trike a while back, with a bunch of gears set up and instead of going for the 1 wheel drive like a lot of trikes do, we went solid axle with extremely reduced gears. The lowest gear on my trike was a 9:1 and the highest was a absurd (especially when we set it up with an electric motor) absolutely crazy fast .9:6. The lowest gear on that trike is the only reason it can make it up hills, haul weight in the baskets and tow little cart trailers. Also the wheels on the back of the trike are actual truck tires, granted they are as skinny as you can street legally get, they still weigh a good few pounds each, and with the lowest gear on our trike you can almost pull a wheelie and on gravel you can easily if you peddle hard enough, break traction for a good few peddles and fling a few pebbles. The motor on full blast will peel out and never catch traction, the trike will never move fast enough to catch traction on gravel, and its not even a super powerful motor either. Frankly the low gear makes trail riding it through muck and things like that super nice. I can't hit certain mountainbike trails but I can navigate the mucky trails and wet trails with absolutely no fear of loss of balance, and I sit high enough on the trike I'll likely never get wet, and with the low gear peddling through everything is so effortless especially if I use the motor. Its funny, every time someone laughs because of it. The thing has enough buoyancy that I can float it across lakes, creeks and rivers, just keep peddling where others either get off and overhead their bikes to get to the otherside, or if Ifeel spicy I'll use the motor with higher gears to paddle faster. That thing can make a wake behind it in my 3rd to last gear. Any higher and the wheels spin so fast it just cavitates the water and I lose paddle power. It gets going fast enough that none of my buddies can swim fast enough in a stretch to keep up with it from a dead stop. I can even let them go first and it will pass them. That trike is my favorite build ever, I should post some videos of the ol' girl, showin' how bad she is at basically everything. I can pull a 0-point turn lawnmower on an open deck 9 foot long trailer like its neigh wightless without the motor assiting me. Just using the gears I have set up.

This is sick 😂 If you ever try this again, try hauling with a fatbike on 27.5 x 4.5” tires with lower tire pressures for traction.

"Earn it, slowly" You summed me.

It's a great day when Seth posts!

Im a truck driver who likes to ride and this video is right up my alley! Im looking to get a foldable mtb for offroad exploring and exercise when I'm held up away from home... lmk if anyone has any suggestions for me. Never bought a foldable before

Add a flywheel to spool up while you pedal! Will be easier to balance!

Finally, a bike that Oscar can keep up without breaking into a trot.

Seth: you’re better off just using an animal Every animal rights activists: say it again and you’re kneecaps might go missing

I remember back in my day plowing my field with my tractor bike!!! :)

I thought my rockhopper was bad with a 30t chain ring and a 50t granny cog. Lol
