FRIEDRICHSHAFEN, GERMANY – August 29, 2012 – BioLogic, a specialist in urban cycling gear, today unveiled the Joule 3 dynamo hub, featuring a patented design that sets a new benchmark for weight, size, and efficiency. The Joule 3 was also awarded a prestigious 2012 Eurobike Award.

“To put it bluntly, most dynamo hubs on the market are a bit of a drag to ride, literally.” stated Kevin Chan, BioLogic product manager. "They add noticeable drag, and extra drag is the last thing you want to feel when you have five miles going into a stiff headwind. That’s why we’re so excited about the Joule 3 — it’s a benchmark design that is an incredible combination of low weight, compact design, high efficiency and high power output.

In controlled laboratory tests, the Joule 3 reaches 73% efficiency while most top-selling hubs on the market reach a maximum of 55%. The higher a hub’s efficiency, the lower the drag riders will experience. The lightest configuration of the Joule 3 weighs only 355 grams and can be built up into a 20" rim set weighing only 695 grams.

The Joule 3 comes in multiple variations — 100 mm OLD/32H/disc for traditional city/trekking/mountain bikes, and 74 mm OLD/20H for small-wheeled recumbents, trikes, and folding bicycles. The Joule 3 meets German StVZO standards.

In addition to the Joule 3, BioLogic also announced that the Joule HG On/Off dynamo hub is ready for the aftermarket. The Joule HG is a dynamo hub that can be switched on or off: in the “on” position, the Joule HG is one of the most efficient hubs on the market and in the “off” position, the magnets are pulled away from the core of the hub so that there’s zero extra drag. The Joule HG weighs 656 g with an output of 6V, 2.4W.

The Joule 3 and Joule HG will be available worldwide in November 2012 for €150/US$150 and €200/US$200, respectively.

BioLogic will be showcasing its product lineup at the Eurobike tradeshow in booth B4-501 and at Demo Day at booth #101.
