I've had a Cateye Micro Wireless cycle computer for quite some time now (it used to be on my Trek Valencia) and I had always meant to attach in on my Brompton, but didn't. All along, I thought the computer and the sensor would get in the way of the bike's fold.
After much procrastination, I finally decided to use it. It was easy to mount the computer on the M-bar and attaching the analog sensor on the fork using zipties I bought at the hardware store.
And surprise, surprise, the computer and analog sensor did not get in the way of the fold. Not at all.
A problem came up, though, in inputing the wheel circumference [L (mm)] unto the computer. The Cateye Manual that came with it did not have a computation for the Brompton's tire size (16 x 1 3/8).
Fortunately, there's the internet. I found Sheldon Brown's Cyclecomputer Calibration Chart and there it was! 16 x 1 3/8 = 1282! So I entered that in the Cateye Micro Wireless and rode the bike to test if the code was correct. I biked to a place which I knew was 1 kilometer from my house, and when I got there the reading was 1 kilometer. Excellent!
I used the Cateye Micro Wireless Cycle Computer in my recent bike tour of Ilocos Norte. It was useful because I knew how fast I was going, my pace, and the time and distance I covered. It gave me a more informed perspective of the ride, which is always good.
