Dynamo

​Remember those "bottle"-type dynamos that rubbed against the side of your bike tire in order to power the lights? Well, they've gotten a high-tech makeover, in the form of the CadenceX generator – its creators say that it can replace the batteries currently needed for all bicycle electronics.

Miami-based startup Spinetics says its new CydeKick Pro generator can turn your pedal power into the phone-charging and headlight lighting kind without adding any (significant) friction.

Not only does the new Powermonkey Expedition portable charging kit include standards like a clamshell solar panel, AC adapter and crank charger, it complements them with a portable wind/river turbine. Simply connect the generator component that's most suitable for the current conditions.

German inventor Dirk Strothmann certainly caught some peoples' attention last year, when he released his Magnic Light touchless dynamo bike light. Now he's about to launch the Magnic Light iC, which will offer some interesting new features.

Mipwr Dynamo is an iPhone case with a hidden lever that can be pressed down repeatedly to charge the battery, but is still slim enough to fit in your pocket. One minute of squeezing the lever will equal about 30 seconds of talk time, according to the designers.

The new Tern Eclipse S18 folding bike is designed to combine the convenience of a small, foldable bike with the performance of a more rigid platform. It also offers a few convenient technologies built in, including an integrated tire pump and light system.

The onboard battery of the Sun and Cloud camera from Superheadz can be charged via USB, a small photovoltaic panel or by a side-mounted hand crank.

Etón has released pricing for the BoostTurbine and BoostBloc portable device chargers that premiered at IFA 2012.

Eton Corporation launched the BoostTurbine and BoostBloc USB battery packs from the Power Boost range at IFA 2012 in Berlin.

The Magnic Light is a contactless dynamo bike light, that reportedly utilizes eddy currents to produce electricity.

CES Unveiled saw Eton displaying its new FRX Series of self-powered safety radios and its new battery- and solar-power Rukus portable Bluetooth sound systems.

The BioLogic ReeCharge allows you to charge USB bus powered devices with the energy you generate with your hub dynamo as you ride.
