FFTW with threads
Pictured is my bike after an 11 mile evening trip. On the back is a solar battery I use to keep my cellphone alive on long bike rides. The solar panel probably won't help much during the ride. I only need the battery when the phone is tracking the trip or being used for navigation. On multiday trips my phone won't run all of the time and the solar cell should help put energy back into the battery. We'll see how well that works in practice. I have yet to mount the battery on the back bag, but have some hook and loop fastener strips I plan to adhere to both.
From the bag a USB extension cable brings the power from the battery to the front of the bike and on the handle bars is a cellphone mount. I've been making a lot of use of GPS tracking during my rides, and occasionally use the map for reference. The clip does a pretty good job, but on rough trails the phone will slip. I've never had the phone fall from the clip, but it does move around and need to be corrected. The biggest problem is the placement of my volume and power buttons. A good bump and the clip slides into them and can change volume or turn the phone off which is kind of irritating. I have to keep the phone vertical because I found that if the screen rotation is on, the bumpy ride just rotates the screen constantly. Aside from these issues, however, I like having the phone on my bike.
Both the head light and tail lights on my bike are some of the brightest I could find. My head light is 1400 lumens and produces an impressive amount of light, and the tail light has a 1 watt LED. Both should help motorists know I am on the road, and I'd rather they notice me than not.
