Fast fixie: Bicycle with giant chainring aims for 100 mph

Most of us don't put much thought into the components that make a bicycle move. Things like chains and chainrings are pretty much out of sight and out of mind as we peddle along. With Donhou Bicycles' 100-mph bike, you can't ignore the chainring. It's so big, you could serve a large pizza on it.

The Donhou bike has a purpose in mind. It's made to go fast. The strange-looking handlebars keep the rider hunched forward in an aerodynamic position. That humungous serving plate-size chainring then goes to work to propel you forward at speeds your Huffy would never even dare to dream of.… Read more

Feel like riding a bicycle made of bamboo?

We've seen bamboo speakers, laptops, stylii, iPhone cases, and even a concept car. Next up: a bicycle.

We have to be clear: This isn't a bike for cycling enthusiasts or speed demons (there's the Storck Aero2 IS TT bike for that), but for those who want something a little different from the crowd.

Singapore-based startup Bamboobee is taking a ride on Kickstarter and aiming to launch two series -- the Revolution and the Sunny (named after co-founder Sunny Chuah). … Read more

Track your stolen wheels with BikeSpike

You've got the quality locks, you've seen the how-to-lock videos, and you're very careful about where to leave your bicycle. But is that enough?

Not according to the backers of BikeSpike, a GPS tracking device being promoted on Kickstarter.

If a thief makes off with your ride, the BikeSpike will show its map location on your mobile device or home computer. Police can be given access to the data to help recovery. … Read more

This lock hides inside your bike frame

Here in bike-friendly Portland, hipsters tend to stash their U-locks in their back pockets, which makes for an unfortunate view for the rest of us -- the heavy-duty locks can make even the skinniest of skinny jeans sag.

Enter the InterLock, which hides inside the bike frame itself and, with just a few days left on the clock, is nearly funded on Kickstarter. (As of this writing, more than 800 backers have pledged almost $37,000 of the $48,000 needed.)… Read more

ReCycle bicycles made from all-recycled aluminum

Bike riding is already a more environmentally conscious pursuit than driving around in a car, but you can really take it to the green extreme with a bike made from 100-percent-recycled aluminum. ReCycle is working at raising funds on Kickstarter to put its first full run of bikes into production.

There are some nice design tweaks that make the ReCycle bikes stand out. The usual seat tube support is gone. Two of the models have belts rather than chains. The eco-friendly aspects go beyond the use of recycled aluminum. The bikes also have saddles and grips made from cork. … Read more

My Best Tech Gift Ever: Garmin's Edge 500 bike computer

Every day this week, a different CNET writer or editor will recall a tech or geek-centric present that left a mark. Read past stories by Eric Mack and Jeff Sparkman, and look for another installment tomorrow at midnight PT.

It's easy to set personal goals and then let them slide into the abyss of good intentions. The tech gift that really stands out for me is the one that's helped me prevent that from happening.

It's Garmin's Edge 500 bicycle computer, which my wife gave me for my birthday in 2010 (though honestly, I asked her for it). This summer, near the end of a soul-sucking, endurance-testing ride, the Edge 500 came through for me once again.

I had set a goal to finish a ride called Ramrod (Ride Around Mt. Rainier in One Day) in less than 10 hours. But 7 hours into the ride, it was looking bleak. I'd covered 104 miles and done most of the 9,000 feet of climbing. To attain my goal, I needed to cover the final 45 miles in three hours. Certainly doable, but I was pretty cooked. … Read more

Sparse bike lights designed to frustrate thieves

If you want to steal Sparse bicycle lights, you're pretty much going to have to steal the whole bike. The Sparse headlight is called the Spacer Light, so named because it sits beneath the handlebar stem. It features a 3-watt white LED and can be set to on, off, or blink.

The 1-watt Sparse taillight slips onto the seat post. As with the Spacer Light, you would have to start removing parts of the bike in order to steal it. Both lights are made from die-cast aluminum to stand up to the elements and the jostling of biking.… Read more

Bike parts get artists' imaginations in gear

You know that greasy bike chain sitting in the corner of your garage? Take a look at the below gallery of original art made from bicycle components, and you might think twice about getting rid of it.

Chicago-based bike parts company SRAM gave a group of handpicked artists a box each of 100 high-performance bicycle components and told them to craft something amazing. They responded with everything from a bike-centric interpretation of Vincent van Gogh's famous "Starry Night" to a robotic ostrich, a crawling "Sramantis," and your typical Mary Jane-wearing bike chain quadruped with a plastic baby head. … Read more

Xfire safety laser light makes a portable nighttime bike lane

Here in Albuquerque, we have a 5-feet-to-pass law. You need to give cyclists that much room when you go around them in a car. It's easy to visualize when you have marked bike lanes, but some drivers push the limits on unmarked streets, especially at night.

If bicyclists carried their own bike lanes with them, it might help alert motorists to give them proper room. That's where Xfire's clever Bike Lane Safety Light comes in. The light uses two 5mW red lasers to create bike lane markings and five red LEDs for increased visibility overall. … Read more
