Night bicycle rides with the Light and Motion Seca Family

The perfect light for mountain biking.

Extend your riding season with a Light and Motion light. There are a variety of lights to choose that match your riding style. Whether you like to do long, romantic rides at sundown or bomb down some fast singletrack during a full moon, we've got your light.

Stop by the shop for a demo light or join us on our Thursday night rides. Check Facebook for details.

Get lit with the urban rando series from Light and Motion


Ultralight and small enough to throw in a jersey pocket or backpack and bright enough to stand alone, the Urban series is a perfect addition to any mountain biker's arsenal. With the easy strap system the light mounts on and off quickly and efficiently.

Exend your bicycle season and ride at night with Light and Motion.


The ultimate light for night-riding, the Seca delivers an unparalleled level of quality, performance, and reliability. Custom optics harness the power of a 6 LED array using the best parts available to throw a beautifully controlled beam pattern.

Light and efficient are the Taz bicycle lights from Light and Motion.


Fits in the palm of your hand yet outshines a car headlight, the lightweight Taz brings powerful illumination in a self-contained, rechargeable system. Bright side-amber lights give greater visibility on roadways, yet can be turned off once you hit the dirt.

A light to use during epic 24-hour bicyle races or during weekday rides. This does bike light does it all.


The Imjin's micro-peened reflector has been optimized to deliver incredible performance from a proven design optimized for effective illumination. The beam pattern is more focused than the Seca, but can efficiently deliver a tremendous amount of lumens / run-time with lightweight 2 cell battery options.
