Enthusiasm for the bicycle has grown into an enormous culture, with everything from massively expensive one-off bikes to fixie obsessions and cities touting its green transportation possibilities (see NY, Paris, Amsterdam, et all). This is probably why we're seeing an explosion of bike-related technology cropping up around the world. If you live within biking distance of your work and aren't already riding one there, these advancements may change your mind.
Bike-Powered USB Charger
Silverback Labs has integrated into its Starke series what DIY-ers have been doing for a while: a USB charger that runs off of the bike's movement. When it's not powering the lights, the hub-mounted dynamo can charge any USB-connected device (though we don't recommend the USB George Foreman). Make an inquiry on their website for more info.
A hidden camera called the Hindsight is mounted to your seat and lets you see behind you. The camera is wired to a 3.5-inch LCD monitor in the handlebar and gives you a live feed as well as recording what it sees. This is especially important for commuters worried about hit-and-run accidents. You can preorder the Hindsight currently and they're due out in December of this year.
Self-Destructing Bike Lock via Wired
The StayLocked is a security device integrated into the frame that makes the bike unridable if it's broken. The lock comes up from the rear wheel into the seat and swings around to be secured to a sturdy object like a light post. If somebody breaks the lock and tries to ride the bike the bike will collapse. Of course it could still be sold for parts but it's still a useful deterrent. This bike lock is a working concept, however mass production isn't slated just yet.
MIT's Copenhagen Wheel
This big red hub can turn any bike into an electric hybrid. Created by MIT's SENSEable Lab, the Copenhagen Wheel was created to enable riders to expand their distance and does so by storing the energy created when braking, like the Toyota Prius. The wheel is controlled through your iPhone and gives you data related to the city you're biking. It's won the U.S. side of James Dyson Awards and also been featured prominently on the Showtime show Weeds. The Wheel will go into production in the next year and will be available for $600.
And if all that isn't enough maybe you need the bond bike.
