USB-WERK by Busch & Müller

For all those who want to send and receive email while cycling, or use GPS, MP3 players and other electronic devices while rolling down the road, we now have the USB-WERK from Busch & Müller. The USB-WERK is wired to your dynamo in parallel with your headlight. Of course you don't need a headlight, but if you do, wire it in parallel with the USB-WERK and you're all set.

An optional extension cable offers the possibility to tap into USB-WERK's energy supply at virtually every spot on the bike. Cable screw connections keep the connections securely water tight. In order to mount the "miniature powerhouse" on the bicycle frame, three differently sized o-rings and cable straps are included.

Some devices, such as many iPhone models, require a constant voltage from the charger. For devices like this, an intermediary or buffer cache battery must be used. The USB-WERK incorporates a cache battery within the housing. There is no need for an additional cache battery.

A standard USB connector cable is included with the USB-WERK, so just plug in whatever device you want, provided it is charged via USB.

The USB-WERK sells for $ 148.00

Note!

Most devices that charge via USB need .5 amps. Some devices require more amperage to charge than others. And hub dynamos have only so much amperage to give. If your device requires 1 amp, your hub dynamo won't be able to charge it. You should check the specifications on your device and determine that the input amperage is below 1 amp before buying the USB-WERK. The USB-WERK can delivery 1 amp when the internal cache battery is charged. However, since the hub dynamo cannot produce that much power, the battery will steadily drain. Once it has fully drained, the USB-WERK can no longer charge your device while the device is running. And keep in mind that some devices cannot be charged and run simultaneously.


Will it Work with Garmin?

There have been questions lately about Garmin's newest GPS units for cycling. We just received the Garmin Edge 810 and have tested it with the USB-WERK. It works perfectly. If you don't yet have a GPS and were thinking of getting one, the Edge 810 is quite nice, and you can keep it fully charged while you ride.

Universal Cockpit Adapter

mount

A handlebar mount for holding the device you charge with the USB-WERK is also available. The Universal Cockpit Adapter mounts easily to the handlebar without tools. Thick cellular rubber coating on all contact areas of the holder cushions shocks and prevents scratches even on the most sensitive surface. The adapter opens gently upon pressing the rear release button. The holder's inclination can be adjusted variably, thereby offering optimal visibility for every kind of display. An opening at the bottom of the adapter provides enough space to connect cables, so that power supply for inserted devices is ensured at all times, e.g. from the revolutionary USB-WERK charger.

Remember that while the USB-WERK can be used in all weather, your electronic device might not be weather proof. And, USB connections are not weather proof.

Which hub dynamo to use?

Most dynamo hubs are designed for use with 700c rims. This includes all of the Shimano hubs, the Sanyo hubs, and SRAM models, and all of the various Schmidt dynamo hubs with "28" in the name. In accord with German law, when used with a halogen bulb headlight, the system produces a very bright light by 5mph. Schmidt also makes a variety of hubs for smaller wheels, like the SONdelux, SONXS and SONXS100.

It's becoming popular among night riders using 26" or 700c wheels to use one of the Schmidt hub dynamos designed for small wheels such as the Schmidt SONXS100 or SONdelux. When you use one of these hubs with a larger rim, the hub is rotating at a slower rate than it would be if used with a 20" wheel, when riding at any given speed. The slower the hub rotates, the less power it delivers, and the less drag there is. With the new LED headlights, you can still get a very bright light at a low speed, lower than you would with a halogen bulb headlight. This results in slightly lower drag, because the hub is generating less power. But the LEDs need less power than a halogen bulb, so it works.

But what if you want to use the hub's output to charge a battery as well? If you use a hub designed for a 20" rim but instead use a 700c rim, at any given speed, you'll have less power available for charging a battery, because the hub is rotating at a slower rate than it normally would at that speed. It will still work, but the charging time will increase a bit. So if you're going to use the E-WERK, or think you might in the future, you may want to think twice about how important that small difference in drag is to you. The drag of a SON28 hub with a 700c rim is tiny. So a SONdelux hub with a 700c rim is a little less than tiny. Do you care? Should you care? If you know for certain that the E-WERK isn't for you, pick your dynamo hub based on quality, performance and price only.
