AeroTech Evolution Protective Bike Case Lets You Fly With Two Wheels


If you're an avid rider of bikes, the rough part about traveling is not just going without your set of wheels for an extended period of time, but trying to transport them on a plane--risking damage to the frame and wheels. The AeroTech Evolution bike case seeks to change all that.

Video: Internal Gyroscope Is the Future of Training Wheels


Did you use training wheels when you learned to ride a bicycle? My dad was convinced they slowed down the learning process and taught bad habits, so he just held on to the back of the seat and ran down the street with me while I pedaled. Then he let go and I fell over. Rinse knees, repeat, until I caught on to the trick of keeping my balance.

A Foldable Electric Bicycle for Your Urban Commuting Needs

The YikeBike mini-farthing zips along at 12 mph on a little electric motor

If a Segway and a foldable scooter got together, they might hope to conceive something like the YikeBike mini-farthing. The foldable electric bike resembles a sleek, futuristic upgrade of the old high-riding bicycles, and it can fold up for easy storage under a desk or in a cupboard.

Biking Downtown Could Help Power The Bus That Gives You A Ride Home

A new bike-sharing program stores the kinetic energy from the bikes to power buses, and gives cyclists a free bus ticket for helping out

We've told you about bike-sharing programs before, but the Hybrid2 design by Chiyu Chen takes the idea one step further, by using the bikes to put power back in the system. The idea is to put "ultracapacitors" into the bikes that will harness and store the kinetic energy generated by pedaling and braking. Once you return the bike to its rental kiosk, the energy stored in the bike will be transferred to the city's smart grid, and used to help power hybrid buses.

Simple Innovations: The Bottle-Top Bike Clip


The Bottle Cap Bike Clip:  Matthias Ries
I've never wanted to attach a water bottle cage to my bike; I like it to be as free of clutter as possible, both for aesthetics and to keep the weight low. But I can't say that I've never wanted to have a quick drink handily accessible when I'm riding without a bag.

That's where this bottle cap clip concept by Matthias Ries comes in.

Bike Sharing Gets an Electric Update

New electric bike concept could fill transit gaps

Bike sharing is an urban transportation program gaining popularity worldwide, providing public bicycles at designated points around a city--find it, ride it, drop it off at a kiosk down the road when you're done.

Cykel, a concept bike sharing system by Brian Mcallister able to switch between pedal-power and electric motor, could open up the program to new demographics, increase the range of most bikers, and make cities with more difficult topographies more accessible. Not to mention making the typically pedestrian-looking shared rides a lot slicker.

Easy Rider

The Harley inspires a zero-maintenance, belt-driven pedaler

How do you make a bicycle that never needs lube, never leaves grease on your pants, and always delivers smooth pedaling? Simple: Ditch the chain.

For its new Soho commuter bike, Trek replaced greasy metal links with a dry belt. Unlike other attempts at such bikes, the Soho is silky smooth to pedal. And it’s the first to offer multiple speeds, using an eight-gear transmission inside the rear-wheel hub.

The 2009 International Motorcycle Show

Art director Matthew Cokeley leaves the warm PopSci offices to check out the next wave of bikes

Motorcycles are the epitome of the phrase "form follows function." And nowhere is that more evident than at the 2009 International Motorcycle Show. Kicking off this morning at the Jacob Javits center on Manhattan's west side, Popular Science braved the blistering cold to see what's new and what's next.

Here is a sampling.

A Better Biker's Boombox

The size may have shrunk but the sound is just as big

Blasting some music while riding a bike isn’t a terribly exciting or technologically novel concept. In the mid 80’s grown men would hoist a boombox pumping Run-D.M.C with one arm while controlling their beach cruiser with the other. The Cy-Fi wireless speaker ($199.95) is a long overdue evolution in cycle speakers and it's a bit easier on the back. While it offers no singular technology worth noting, the finished product is as simple as it should be, a feat rare in modern electronics. We tested the iPod speaker (there’s a Bluetooth model as well) on the local boardwalk in San Francisco.

A Better Fit for a Better Bike

Professional and amateur cyclists alike get an instant fix with the world's most high-tech fitting system

You may never forget how to ride a bike, but remembering how it should fit is another story. For competitive cyclists, even minute adjustments to the frame can have a major impact on comfort and performance. Despite this, bike fitting has long been a black art with each technician employing her own method and metrics (plumb bob, video, rulers, etc.). Most methods have been inaccurate, tough to reproduce and based on the static position of the rider (not pedaling). Meanwhile, opposing views on the right fit have been difficult to reconcile without a standardized measurement method. Now Retul has introduced a motion-tracking system that may put those issues to rest.
