After reading through alot of threads on various forums and reviews, I finally settled on a Fenix L2D CE for my front light. However, I wanted to mount it to my bike in a way that was easy to get on/off and able to easily use the torch by itself. I used a TwoFish lock block for about a week whilst waiting to make my own mount. The TwoFish lockblock worked quite well and was quite secure, but slightly annoying to have to open/close the Velcro when I wanted to remove the torch from the bike.

Basically I gutted one of those cheap 5 LED front bike lights. I removed all the internal bits till i was just left with a shell and made a hole in the plastic at both ends of the bike light. The shell obviously has clicks into the mount on the handle bar and comes on/off easily.



The light is almost a perfect fit for the Fenix L2D CE. The diameter of the front and back is just slightly larger than the diameter of the torch. With some careful drilling and filing I got two holes at either end that fit the Fenix tightly. Also two of the grooves on the Fenix line up perfectly with the back and front of the bike light. I used a couple of o-rings to sit in the grooves to stop the Fenix moving back and forth.


You can see the grooves that line up with the bike light.

One last pic showing how the diameter is almost perfect for the Fenix.



Hope that helps others with ideas on how to attach their Fenix. The bike light is available from DealExtreme for USD4.62 with free shipping. Though I've seen this particular lights in heaps of different places.
