The Reevo hubless e-bike is a wild-looking electric bike loaded with high-tech features like fingerprint security, GPS tracking, and built-in LED lighting. It also doesn’t have traditional hubs and spokes or drivetrain, and it is the most unique bike I’ve ever reviewed. – Watch.

LOL, Who ever invented this stupid thing should have spent more time studying the effects of leverage. Gotta be the dumbest thing I’ve ever seen.
Why? They raised 6.7 million from suckers and then left town. That’s why. Kinda like windmills and solar panel companies.
@Brad
The loads on those front wheel bearings must be off the charts.
It’s the Rivian of bicycles.
“The loads on those front wheel bearings must be off the charts.”
If I had the time, and was extremely board, I’d model it up in Pro E and calculate the psi. But I already know it would come back “off the charts”. LOL. Imagine getting a flat on one of these things.
Use DDG to search for “hubless wheel bicycle motorcycle” and you’ll get quite an eyeful. There’s been an awful lot of reinventing the perfectly good wheel.
but this Reevo’s got nothing on the TMC Dumont motorcycle.
It’s…it’s…it’s…wrong. Just wrong.
As a joke, two guys invented square wheels and tried them out on as car. Needless to say, the square wheels did not work and the car didn’t get too far. I think I saw it 10 years ago and its probably still on the internet somewhere.
As bad people trying to re-invent the wheel are word-venters that like to invent out of their noggins new words for old things that already have a plethora of words that name them. See what I mean? Or, maybe they bring back old Greek words for things we already have names for.
@Tim Bukto — I kept tellin’ ’em and tellin’ ’em that square wheels were going to be too bumpy. Each time the wheel goes around, you get four bumps. But with triangular wheels, you only get three bumps. They’re 25% less bumpy!

I’ve been sick and slept most of the day, so you’ll have to put up with me tonight. LOL.
That design you linked is miles ahead of the dumb shits in the original post. Sort of. The original post all the pressure was in a down word fashion towards the center of rotation. The design you posted at least applies pressure back to the rim. A rim job. LOL.
However, high speed motor cycles get stability the faster they go do to the gyro effect of a cylinder rotating at super fast rpm. I’m doubtful that would happen if the cylinder is not attached at center line. Wake up Jethro, we need you.
@Brad — Me and the President are ORDERING you to get well and feel better. Now hop to it!
A hubless wheel will still act as a gyroscope same as a wheel with a hub. The difference is that the axial force of precession will have to act on the rim instead of the axle. If you think (correctly) that the strain on the hubless wheel bearings will be really high in straight ahead rolling, you’ll see that it’ll be completely crazy in turns.
“As a joke, two guys invented square wheels and tried them out on as car”
There were a couple guys that built a bike with square wheels. They used a Geneva Gear at the hubs. I guess you could say it worked. I’m guessing the squares were at minimum 32 inches. So every time they hit the poitny end of the square the seat rises (16 x .70711). Yea, 11.31 inches. Not a comfortable ride and a total waste of time.
The Biopace chain ring was all the rage in the 1080’s. I rode a few and you couldn’t spin with them. I was riding 40 – 60 miles almost daily back then after work. I thought them a gimmick and that was validated. Same with most of the bullshit the goofballs came up with and was touted in the Fake Bicycling magazines. Most all of it was solution going looking for a solution. The studies were sucker bait and were nothing but “studies,” done to backload “data” and manipulate it into supporting a foregone conclusion. That hobby is chock a block full of leftwing screwball types and it was useless to try and discuss the flaws in the methodology used in “studies” and the fact that they were falling for a line of bullshit. Point anything out that bursts their bubble and they start crying about the science and experts and you don’t understand. The problem with that is I demand that the scientific method be followed and that the RAW data and methodology be disclosed and thoroughly examined. You guessed it, you are as likely to get that as you would the same request for Global Warming “study” data and methodology.
How many tons of petro-chemicals were burned to make that abomination?
The Coriolis effect is some crazy shit. You feel it every time you ride a bike. the faster you go the more stable you feel. It’s why a top spins on its tip and doesn’t fall over until it stops spinning. It would take some serious free body diagrams and mathematics to see where all of those forces go within the wheels and frame. Just the force from gravity on the front wheel mount creates a completely unnecessary moment load that must put a hellish stress on those wheel bearings. Every bump is trying to rip it off the rim. I think there is also a brushless motor within the wheel for lazy people who don’t want to peddle. That grinding noise is probably a regenerative system that uses the motor to charge the battery while coasting (like EVs). I bet there is a switch in the app that turns it off while peddling that he didn’t know how to operate.
Tim Buktu, square wheels only work on the planet Bizarro in the old Superman comic books where everything is upside down and ass backwards.

…huh.
I know we’re all old here, but appaently you’re older than I thought…
It’s so gay…

The Greenie Weenies love this sort of crap. Could have sold thousands more with the claim that it helps save the planet. You don’t even need to say how.
EV…no way.
INDUSTRY 9 in Asheville NC, builds the BEST Mountain Bike CENTER HUBS & STEMS in the world, Bar None.
ALL 5 of my LEG POWERED mountain bikes are equipped with these components and they AIN”T CHEAP!
I always hesitate to slam attempts at engineering innovation. Except politicized bullshit of the left.
Call me what you will, but I think we could get free energy from a combination of two free forces working together: magnetism and gravity.
Like this – a simple example. put a little steel ball on top of a pole that has attached to it a slide, like a kid’s slide, but only wide enough for the steel ball. The top of the pole has a strong magnet that can be switched on and off. Turn off the magnet and the ball falls down the slide. Capture the energy of that fall. We pay nothing for it. Then turn on the magnet and the ball goes back up. For free. We keep the energy of the ball falling down by free gravity. Do that 20,000 times a second and we’re talkin’ serious amounts of free energy.
Ya’s all get the idea? Now send me some money for the start up cost of my company, Balls In Motion Corp., and we’ll all strike it rich.
