Being a motorcyclist for the past 50 years, when I saw what you were building, I thought so much un-sprung weight, so many issues to make that work. But you you did it. Congratulations, Well Done! Keep up the amazing Fab work.

stopped everything i was doing to watch this, the only thing i've been looking forward to on youtube.

[OSXMan]

There's got to be a tremendous sense of pride building something so unique. Truly a one-off. So impressive.

[Godfirst]

People that can engineer then build something this rare… nothing but my utmost respect and admiration.

[doggonedk]

When you said 863 lbs.
I almost fell out of my chair. Cuz that is exactly what my 1983 Kawasaki 1300 6 cyl. Voyager Weighed. Smoothest bike down the road I ever threw a leg over. The thing even had an onboard air compressor to adjust ride quality and height. When you get ready to ride that thing out on the road you need to get a black helmet with little ears and a black cape.
IM BATMAN!
Nice work Ethan

Now build a mirror image chopper, and you can combine them into a 4 wheel terror that splits back into two when the trails get narrow. Then recombine it again.

Suggestion for you on prepping future tires. Why not build a jig that holds a seven-inch grinder with a flapper disk, and glides in the preferred arc shape of the tire?

Have the tire rotating at constant speed, while the grinder reciprocates back and forth on the arc rails (think like a roller-coaster track in a semi-circle the radius of the preferred tire curve). Build the whole arc/grinder setup on a vertical, variable-height, track setup (could use a trailer crank jack to adjust the height until the edges of the tire are at preferred radius).

How it would operate: 1) Mount the new tire in the jig and get it up to a slow, constant rotation. 2) Turn on grinder/arc device, which continues to sweep back and forth along the arc track. 3) Use the trailer jack to lower the grinder/arc device a sixteenth (or so) of an inch every time the tire comes out of contact with it.

End result should be a nearly uniformly worn, curved tire face.

I'm only suggesting such a tire jig be made if you plan on needing to make several more tires for various projects (and, a bonus, you could be doing other things while the jig is in operation, only needing to readjust the cut height periodically throughout the process). Just my humble thoughts.

I'm a welder/fabricator and I absolutely love the work done on this! It's some excellent engineering.

[aquatoad]

You guys are probably one of the only channels I watch where I can sit through a video thats half an hour or longer and want more instead of clicking off after 10 minutes and builds like this is exactly why. just insanely cool builds that are like a dream scenario come true

[themeandrousengineer]

I think everyone has thought about making something like this, but no one has actually done it. Well done.

[SentAndBent]

First video on this series was over 7 months ago! This was a WILD amount of work! Can not wait to take it on the streets...

[richarddoyle]

You need a cush drive. A damper, normally rubber between the sprocket and the wheel. It will absorb a lot of the shock that is recking the chain, sprocket and probably gearbox. .👍

[OMGWTFBBQSHEEP]

I really enjoys the long un-cut shots like the one from 8:30 to 10:30! Thats two whole minutes without a single cut. Makes it feel so authentic and makes it more engaging

[PortRhouse]

The wait was so worth it! The monster chopper does indeed rip, and so much better than I expected. Once you get the chain tensioner, maybe improve the brakes, and get this thing fully cleaned up and painted it is going to be a thing of beauty. A murdered out all black look and this thing would become the bat bike.

[kumiteu]

Looks like something Batman would ride

[skylark]

I have been thinking for months that this thing was going to just instantly kill someone. So awesome to see it rip! Such an iconic piece of art. Congrats!

[dylaancruz]

this just made my young spykids childhood happy.

[Lilcurf]

As an autozone worker, those duralast jump boxes have gotten me and my buddies out of a LOT of sticky situations. Thank you for buying our products ethan! :)

[olekaarvaag]

24:29 Right after Ethan points out it could use a chain guide because of the bouncing you show a clip where that is clearly visible. If that is done with intent you deserve praise dude, nicely done.

I've been kind of skeptical of the rideability of the bike since the start but knew I would probably be proven wrong, and imd glad I was. This bike is going to be legendary.

[Fishpizza]

13:30 Maneuverability can be improved by tilting the steering axis back 20-30 deg toward the rear. Right now, the rider leaning is doing a lot of work to turn the bike, but that can be made easier. Tilting would also improve low speed turning dramatically, likely preventing tipping over. Check out other bikes front steering axis to see what I mean. I'm a Mechanical Engineer.
