Dynamo lighting is the single biggest improvement for safe biking around Portland. With your lights powered by the motion of the bicycle, you are limited only by how far you can pedal. Joe Bike has the largest selection of dynamo hubs, lights, and chargers in the city and specializes in complete system installation with products from Schmidt, Supernova, Busch+Müller, Kasai, Shutter Precision, Sinewave, Velo Lumino, and Shimano.
Here's why we recommend dynamo lighting:
Never worry about forgetting, losing, or forgetting to turn on your lights!
Dynamo power is reliable and doesn’t require charging batteries or carry the risk of your lights dying during a ride.
Enables charging other devices or a cache battery to provide power to GPS, cellphone, or SPOT tracking device.
Wide selection of headlamps with wide, shaped beams for road use (this keeps the light on the road and not in the eyes of oncoming traffic!) or super-bright round beams for trail use.
Tail lights are bigger, brighter, and can even provide an automatic brake light effect!
Headlights and tail lights can be mounted to many different parts of the bicycle, such as the handlebars, fork crown, fork leg, front rack, seatpost, saddle, seat stay, or rear rack mount--just to name a few!
The Best Dynamo Lights for Every Situation
Because there are so many different use cases for bicycle lighting, there may not be a single best headlight for everyone, but we tend to like the Schmidt Edelux II for its wide, consistent beam and excellent durability and build quality. Busch+Müller’s IQ-X, IQ-XS, and Eyc (pronounced “Ike”) are excellent options with distinct beam patterns. The IQ-X and IQ-XS share a similar body design, with the IQ-X gaining the option to change the lamp’s orientation, a brighter and wider 100 lux light beam (vs. 70 lux for the IQ-XS). The Eyc is much more minimalist, with a budget-conscious price point and narrower 50 lux beam field. All three lights feature automatic daytime running lights, standlight function to provide visibility while stopped, and a horizontal beam shape to keep the light focused on the road, and are a great option for commuting and “road plus” riding.
All of these lights can be paired with a variety of B+M taillights, from the extremely small micron (µ) to the large Line series or ever-popular Secula or Secuzed. The Micron, Secula, and Secuzed can mount to a fender, seatpost, or chainstay while the Line series can mount to a rack or saddle rail adaptor. The Line Brake Plus features circuitry that detects a drop in current as the bike slows and uses stored power to increase brightness, giving a tail light effect just like a car.
What is a dynamo hub?
Hub Dynamos generate electrical current by using the rotation of the wheel to spin magnets inside the hub shell around a coil mounted to the axle. This can then be connected to a headlight or USB charger with wires running up the fork leg, or internally routed on specially designed forks. Most hubs will be able to fully power a headlight and taillight system at 8 MPH. Some hubs designed for smaller wheels provide less resistance, and consequently provide less power, instead relying on the faster rotation those smaller wheels provide. These hubs, such as the SONdelux, are often considered the ultimate choice for riders who prioritize minimal resistance and overall speed over the low-speed power.
Much like hydraulic brakes, dynamo lighting is one of those things that really must be experienced to truly understand the benefits.
This is one of the best and most reliable dynamo hubs. If you ride at higher speeds, its performance and resistance is preferable to Shutter Precision hubs.

Shutter Precision (SP) makes some of the best dynamo hubs we carry and the PD-8 is by far our most popular dynamo hub, going into the majority of our dynamo wheel builds. SP dynamo's hubs are not only the lightest, but also the most efficient 3w hub on the market. The lightest SP dynamo weighs in at an unprecedented 360-390g, which is lighter than the 1.5w Shimano S701! They also attain an unmatched efficiency of 72%. These 3w dynamo hubs are premium products designed and engineered for the most demanding cycle tourists, commuters and enthusiasts.
The PD-8 comes in a variety of colors! Call and check our stock to see what's available!
Kasai Dynacoil Hub
The Dynacoil is the latest addition to our collection of dynamo offerings and is a similar (if not identical) design to the SP hubs.
These are compact and efficient dynamo hubs for 700c, 650b and 26" wheels. They meet German StVZO standards (K1280) and over the same efficiency as SP hubs: 72% at 10mph.
This was our most popular Shimano dynamo hub for many years. The S501's 6v, 3.0 watt output is still a solid choice for touring or commuting bicycles. It can also power most smart devices via a handlebar-mounted USB port, in conjunction with a Busch & Mueller Luxos U or AXA Luxx70+ front light.
NOTE: Be aware that the bigger your wheel is, the faster you'll need to be going to get your dyno hub to produce power. And this is where the Schmidt SON28 hub beats the Shutter Precision; it supplies lights and a dynamo charger with power at lower speeds than the Shutter Precision. This may not matter if you're on 26" wheels, but if you're riding a 700c/29" wheels and staying below15 mph, the better option is the Schmidt or American-made Sinewave Cycles Reactor.
