Cyclotron: a hubless, spokeless bike getting funded on Kickstarter

OK, now if we would have looked at this a month before it started its crowdfunding campaign, like many people I might have just dismissed it. I mean come on, are we really ready for a Tron-looking bike built around hubless wheels? Or is it even ready for us? The answer to that is apparently, yes. More than enough people have put their money where their mouths are to more than double the funding the Cyclotron bike team needed to get their project out of technology and design development, and off the ground towards production. Take a closer look with us at what could be one of the most technology-integrated bikes rolling around town, with it built-in electronic shifting gearbox, sensors, lighting, and much more…

Another Hubless Bicycle Concept, Except This One Rocks

There are lots of hubless bike concepts that we’ve posted, but this one was actually made, has a belt drive, was ridden and has a cool video to prove it. Plus, just based on looks, it could ever so easily be made into a folding bike for campus and city livin’. Here’s the blurb on it from Makezine:

The aim was to use a hubless wheel to create a compact bicycle, with the benefits of a large wheel and belt drive.Hubless wheels have appeared in bicycle concepts already, and were first invented by Sbarro. However, few concepts have made it to prototype and when only used for aesthetic purposes, the disadvantage of extra cost out weights the visual gain. Lunartic uses the hubless for a reason; to house the working parts, reducing the wheel base but not sacrificing conventional riding geometry. Lunartic is supposed to be as compact as possible without folding or being awkward to ride, however there is the potential for the front wheel to fold up into the rear or for that space to be used for a laptop back, motor or dynamo.

See it in action: Video after the break…

Futuristic Hubless Bicycle Design

futuristic-bicycle-design-2

Designer John Villarreal, from Wisconsin, has come up with this futuristic concept bicycle.  Intended to offer a peak into the future, as advances in material technology and manufacturing techniques allow the creation of structures that would currently be impossible, this bike was created by paring away everything non-essential to its function. The hubless wheels appear to turn on bearings running around a modified rim, with unspecified futuristic materials allowing the designer to impart enough stiffness without excessive weight. I don’t think that the big wheel makers will be looking to this as the next big thing but, of course, anything is possible in the future! The integrated handlebar, brakes and lights add to the sleek, futuristic appearance which won’t be to everybody’s tastes. Maybe if Michael Knight is looking for an environmentally friendly alternative to KITT he could speak to John Villarreal.

Actual, Real Life Working Hubless, Spokeless Bicycle

yale-hubless-spokeless-bicycle5

Forget those road and bmx hubless prototypes, these guys from Yale have built a working bicycle with no hub, spokes or anything else in the middle of the wheel.

Posted on Reddit, they said only the rear wheel is bare in the middle because they ran out of time in the semester, but that a spokeless front wheel would actually be easier and lighter because they wouldn’t have to build in the drivetrain features.

Speaking of drivetrain, here’s the deal:

It’s a single speed setup. We used two cranks and two bottom brackets in the front to gear up the ratio. It goes from (IIRC) 53 to a 13, which is connected to the second crank and another 53 which connects to the rear hub. The rear hub is just a normal ratcheting rear hub that we mated to our belt pulley. Not sure if all these bike terms are right, but that’s the general idea.

The front wheel would be almost exactly the same as the rear wheel except that it could be a little lighter. Some of the aluminum can be shaved off since there’s no powertrain to connect to.

The wheel/rim itself is made from T6061 aluminum.

Hubless Concept Road Bike from Bradford Waugh

Right on the heels of the hubless BMX bike concept we found, here’s a similar set up in a road bike by designer Bradford Waugh.  The hubless wheels are driven by geared rollers, but check out the crankset!

Hubless BMX Bike Concept

Found this on Minimalissimo from Russian designer Nikolay Boltachev.  It’s pure concept, built around hubless wheels and magnetic bearings, and apparently he’s looking for help developing those ideas.  Leave some comments with any ideas, and hit ‘more’ to see additional photos…

Week In Review: fancy paint, clever hacks, crazy concepts and more!

bikerumor week in review

This week we saw impressively painted bikes from Scott for the Rio Olympics, Marin reintroducing their classic color fade in honor of their 30th anniversary, and looking toward the future Cyclotron’s hub-less bike fulfilling their crowdfunding goals. There was also a hands-free communication device from Japan to keep you and your riding buddies in touch whether you are riding locally or around the world, a hack to make your reverb work with any lever, and lots more. Skim through all the headlines below so you don’t fall off the back… Continue reading “Week In Review: fancy paint, clever hacks, crazy concepts and more!”

Sada: No Hubs, No Spokes, No Worries, Collapsible Italian Style

Sada_Hubless_Foldable_Bike_ProfileUntil now there have been no obvious benefits to a “hubless” design. We have shown you multiple iterations in past years here and here. But beyond the novelty factor they served little practical purpose. Enter Italian engineer and designer Gianluca Sada. Sada has successfully created a folding bicycling with “spokeless wheels,” making this hubless design highly practical. See the Sada bike collapsed to nearly nothing, next…

Hack! Homemade “Swinger Bike” with Transparent 3-Speed Gear Box

transparent gearbox on homemade swinger bicycle

Tinkerer and bicycle lover Champx has created a transparent three-speed gearbox for his homemade “swinger” bike.

Constructed with cogs pulled from other internally geared hubs, the mechanical design is inspired by old tractors. The cranks drive a spindle with three different size cogs, and a brass slider engages keyed teeth inside the cogs one at a time to determine the gear. These turn a lower spindle, which is then connected back to a larger cog that turns an outer axle with the chainring attached on the outside. It’s all housed in a custom made plexiglass case and mounted to his own bike.

This is one of those projects that’s definitely better shown than told, so click on through to see how it all comes together. And see what a “swinger” bike is…
