Dymotec Sidewall Dynamos and Lights
Dymotec sidewall dynamos are discontinued, and we have none left. I'm leaving the page up because we still have some headlights that are compatible with sidewall dynamos like the Dymotec 6. and we still stock replacement rollers, and halogen bulbs for older Busch & Müller headlights. We will continue to stock these parts as long as they are available from Busch & Müller. The Dymotec 6 is a high quality moderately priced 6 volt sidewall dynamo, perfect for the rider who occasionally needs light at night. Dymotec 6
The Dymotec 6 is very reliable and a good choice for riders with a short commute or limited budget. The Dymotec 6 will power either a halogen headlight with a 2.4 watt bulb and a taillight with a .6 watt bulb for a total of 3 watts, or it can power a single halogen headlight with a 3 watt bulb. It can also power any 6 volt LED headlight I sell, with or without a taillight attached. Since the dynamo itself acts as the on/off "switch", you can use headlights without a switch, saving some money. For riding in the rain, I recommend using the wire roller which as available as a small part. It attaches to the Dymotec 6 easily in a few seconds, just remove the rubber roller and install the wire roller. The Dymotec S6 and S12 have been discontinued. The S6 was a much more expensive dynamo with special electronics to reduce drag, such as was also used in the discontinued 12 volt S12. If you own a Dymotec S6, and you are considering the purchase of a new headlight, be aware that the S6 is not compatible with any of the Busch & Müller IQ type LED headlights. It is compatible with the DLumotec series headlights, such as the DLumotec Oval Plus and DLumotec Topal. Since the Dymotec S6 was discontinued before the IQ lights became available, the IQ lights were never designed for compatibility with the S6. So, if you have the Dymotec S6 and want to use an LED headlight, I recommend the DLumotec headlights, if you can find one. They have been discontinued for several years. I have not tested the S6 with any other LED headlights such as the Supernova, Inoled or Schmidt Edelux. And I no longer have an S6 available to run such a test. But the DLumotec Oval Plus works beautifully with the S6 and you can use it with confidence.
The wire roller is highly recommended for use in the rain, but does require precise alignment to avoid damaging the tire's sidewall. With the standard rubber roller, the dynamo's alignment is still critical. Not only will it increase the drag, it will result in the roller wearing out quickly. It makes sense to order an extra roller when you order any sidewall dynamo. Headlights The headlights for these dynamos do not require a switch since the system is turned on by moving the dynamo to contact the tire. By the way, it's that movement that determines whether a dynamo is right sided or left sided. So the more expensive switched Lumotec headlights that I sell for hub dynamos like the Schmidt SON are not needed. I stock many 6 volt halogen Busch & Müller headlights along with the Schmidt E6 6 volt headlight without switch for use with the Dymotec 6 generator, or any 6 volt tire driven dynamo. And we also have several headlights from Busch & Müller using an LED for extremely long life. I stock a 12 volt headlight and two 12 volt taillights for use with the Dymotec S12. All sidewall dynamos can only be used with a single headlight. You cannot run two headlights from a sidewall dynamo. And with the Dymotec 6, you have the option of using a taillight wired to the dynamo, or just using battery powered taillights. The S12 must have a taillight attached. All of the headlights I sell have circuitry to protect the bulb from burn-out at high speeds. All 6 volt halogen headlights ship to me with a 2.4 watt bulb installed, and are intended to be used with a .6 watt taillight. A 3 watt bulb is optional for the 6 volt headlights when used without a taillight. The 12 volt headlight ships with a 5 watt bulb. 5 watt bulbs cannot be used in a 6 volt headlight. 2.4 or 3 watt bulbs cannot be used in a 12 volt headlight. The LED headlights can be used with or without a taillight connected, and no changes are needed at the headlight. However, for the LED to last as long as possible, it needs to run cool, and to run cool a taillight should be connected. So I highly recommend use of a wired taillight with the LED headlights. Halogen Headlights
Lumotec (6 volt) headlight for use with Dymotec 6 (round). Comes with single strand 185cm wire and connectors. Compatible with any 6 volt tire driven dynamo, including the discontinued Dymotec S6. Price: Discontinued! 2.4 watt halogen bulb is standard. A reflector surrounds the lens for added safety. Add $2 to change to a 3 watt bulb. No brackets are provided with the round Lumotec headlights, but are sold separately. We have replacement lenses for the Lumotec. Replacement lens for Lumotec, Part # B&M470-13, Price: $ 5.75 We used to sell the Lumotec Plus, which has a standlight. It uses a slightly different lens to accomodate the standlight's LED. We still have replacement lenses for the Lumotec Plus in stock. FYI: You can't convert a Lumotec into Lumotec Plus just by changing the lens. Replacement lens for Lumotec Plus, Part # B&M470Di-13, Price: $ 14.00 Schmidt E6B-OS For the most tightly focused beam of any bicycle headlight, choose the Schmidt E6B-OS. By concentrating the light, these place more light further down the road which is helpful at high speeds. Some people will prefer a larger patch of light on the road, so a wider beam such as the Lumotec and Lumotec Oval (above) may be preferable. Also, see the new Busch & Müller LED headlights below. The Schmidt headlight uses the same optics as the now discontinued BiSy headlight, which has been replaced by the E6B-OS
This is the Schmidt E6-OS headlight. The optics are the same as the BiSy, but it is easier to replace a bulb and is more ruggedly constructed. The E6 does not come with wiring or connectors. You need to purchase those separately. See below. Compatible with any 6 volt tire driven dynamo, including the discontinued Dymotec S6. Price: $
LED Headlights Lumotec Eyc Plus
The Lumotec Eyc is new for 2014. The beam is the same width as the original Lumotec CYO with better nearfield illumination. 50 lux is all the light most people will need. The photo shows the T Senso version which is for hub dynamos. The version for the Dymotec 6 says Eyc Plus on the side. There has never been a headlight this good for a tire driven dynamo. The included mount is for the fork crown, and works with most caliper brakes and disc brakes. For cantilever brakes, you'll need the CYO cantilever mount. Since we no longer have sidewall dynamos to sell, our remaining stock of Eyc PLus headlights are marked down. We are closing them out. Lumotec Eyc Plus for sidewall dynamos, Part # B&M160RDi, Price: $ 35.00 B&M CYO Cantilever Mount, part # B&M475DUPB: $ 10.00 Taillights See my Taillights page for all Busch & Müller taillights, fully compatible with the Dymotec 6.

Every dynamo comes with wire, as does every Busch & Müller headlight. The exceptions are the dynamo powered taillights, battery powered taillights, and the Schmidt E6B-OS headlights. We sell wiring separately, so you can carry a spare wire, or connect an E6. We have a single strand wire without connectors, single strand wire with a connector on one end, and we have a double strand wire with connectors on one end. The single strand wire works if you can use the frame to carry the ground. But many bikes won't conduct ground through the frame for a variety of reasons. For those bikes, we have the double strand wire; one side for power, and the other side for ground. On some bikes, you don't need to run two wires from the dynamo to the lights. The dynamo can be grounded to the frame through its mount. Headlights and taillights can often get their ground connection through the frame. So often a single wire to the headlight and then to the taillight is all you need. But there are some situations where you won't be able to do this. For instance, if you mount the dynamo on the front fork via the Dynashoe mount, the ground link would have to pass through the headset. With most headsets that's fine. But some headsets will not pass electrical current through them. Shimano cartridge bearing headsets, for instance, won't allow you to do this because the material used in the cartridges is an electrical insulator. If you mount your headlight with either my custom handlebar mount or the R&M handlebar mount, it will not be grounded to the frame, and you will have to run a second wire. But that wire doesn't necessarily have to extend all the way to the dynamo. You could run a short wire to a metal part on the bike, like a brake bolt, and pick up ground from there. Before placing your order, think about how you want to run the wires. If you have any doubts about whether the included wires will be sufficient, just ask. We'll figure it out together. It's best if you are near your bike when you call if you have questions about wiring.
Double strand wire, 185cm, connectors on one end: $ We also have a heavy duty coaxial wire available, either by the foot, or in pre-cut lengths of 190cm with connectors already attached. It's three to four times the cost of the wire sets above, but very tough. Even the silliest worry worts now have no excuse for not using a wired taillight. ;-)
3mm connector for dynamo, headlight, or taillight: $ 0.32
$ 5.50 Since the 4DLite Plus and the Spanninga are heavier than the Seculite Plus, I don't recommend using them with the Cross Bracket. Spare PartsFor a full list of available light brackets, see the Light Mounts page.
Price: $ 30.00 Take care in aligning the dynamo when the wire roller is used. The wire roller can wear out the tire's sidewall quickly if it's not properly aligned. You want the roller "rolling" not "scrubbing" on the tire.
Price: $ 6.00 12 Volt Lights? Busch & Müller used to make a high quality 12 volt sidewall dynamo, the Dymotec S12. It has been discontinued and are all gone. However, we still stock a few lights for these dynamos.
Lumotec Oval Plus 12 (12 volt) headlight and brackets for use with Dymotec S12 generators. Comes with single strand 185cm wire and connectors. Available now. The Oval Plus 12 looks identical to the 6 volt version, seen below. Price: $ 88.00 5 watt (12 volt) halogen bulb for use with the Lumotec Oval Plus 12 headlight. Available now: $ 16.50 Where to Buy?
