Yeah I love those P7 leds. When pushed to 2.4A and adequately heatsinked I can get 1300 lumens from one. What I would really like to see though is a white phlatlight LED. Too bad they're $200. :/
Which ones are you looking at that are $200? You can get the 9A SST-90 for ~$40 from avnet. I have one stuffed in a light body, and it makes for a nice general use flashlight with a multi-mode driver from taskled.

Well then the price has come down since I last checked. I don't feel like spending $40 on an LED though ATM.

Nice wheels! You could add a tool pouch on back of seat.
and a two wheel light weight trailer of size about 1 square microwave oven, might come in handy. It could also carry a pup tent for camping. Those bike additions are getting more common these days.

I could probably add a toolcase, but I used loc-tite on everything. I don't think those bolts are going anywhere.
There are a few problems with the trailer idea. One is there's really no way to attach it. Two is the extra inertia would likely cause me to crash on sharp turns and fast stops.

About loc-tite... Does it work very well for vibration? I have an engine that seems to resonate with the piston's vibrations, and the carb and muffler fall off. Being two stroke, it does not run *at all* without a muffler, and seeing that physics apply to it, it does not run without a carb either. I put loc-tite on the carb already, but im not sure how long it may last.

So far the loc-tite has not failed me. (good thing too)
