20 Weird Bikes We Can’t Stop Looking At

Instead of tubes and tires, this bike comes with 12 high-performance sneakers arranged into two wheels. That’s one way to get your steps in.

Phil Miller, a mechanical engineer who develops artificial hearts, designed this perfectly rideable bike and took it for a spin around (where else?) Burning Man.

Like riding a bike, but on water. The 40-pound Manta5 Hydrofoiler XE-1 does come with a motor for assistance handling any waves or wakes.

The Standup Varibike functions like a kick scooter, but also has a hand crank for working out your arms.

Fat bikes are great ways to ride on snow, but with a ski attachment you can hit the slopes in a completely new way.

This astonishing 117-foot bicycle made it into the Guinness World Records in 2015. Naturally, it’s a Dutch invention.

The late Life photojournalist John Dominis caught this split-level tandem at a bicycle derby in an undated photo.

Yes, it has only one wheel so technically it’s not a bicycle. But inventor Walter Nilsson made this pedal-powered experiment in the mid-1930s and took it on regular rides around L.A.

In case you can’t choose between workouts, the Oregon design company Aldavia came out with the GlideCycle, which lets you run and bike at the same time.

Taking that idea a step (sorry) further, Lopifit came out with this outdoor treadmill that transports walkers and runners on two wheels.

And if running while biking wasn’t enough, you can also simulate climbing stairs with ElliptiGO’s elliptical bike.

Design executive Judah Schiller made this raft/bicycle hybrid for traveling between Manhattan and New Jersey.

Courtesy of Texas custom bike shop Clyde James Cycles, this bike took three months to make and comes complete with suicide doors.

There are fat bikes, and then there are fat bikes. This one falls into the latter category.

This seems like a normal bicycle, but it has a simple (yet devastating) twist: When you turn the handlebar to the left, the bike turns right. When you turn to the right, the bike turns left.

British YouTuber Colin Furze replaced an entire bike frame with metal springs, because… well, just because. He found that it “rides just like a normal bike—it just does weird things.”

Electric bikes are still kinda expensive, so why not fix a power drill to your chainring like this guy?

The Bicymple rides much like a single-speed—except the pedals are jointed directly to the rear wheel, which means you don’t need a chain (or all that extra bike to accommodate one).

We’re not so sure about this one, but we suppose there’s a metaphor in here somewhere.
