Here is an interesting tadpole (two wheels in the front) tricycle, from 1942, which was used to deliver aircraft parts from one part of the North American Aviation factory to another part of the factory.

I got a chance to try a new version of the lighted flagpole made by Arizona Whip. It has all 20 of the LEDs at the top end of the clear lexan flagpole, just under the flag. This version has blinking lights on one side, with the yellow ones blinking alternately with the red ones. The other side is red and yellow LEDs, on all the time. My neighbors who see me on my commute say I look like a UFO on my Catrike Speed. Excellent, that is just what I was going for!

The pic below is more or less what the Whip looks like coming down the road, but with a long shutter speed the LED lights leave streaks across the picture.

Bruce (trikebkdr) has started a new forum called Trike Doctor which specializes in trikes and their repair issues. This is the same Bruce who has authored several posts on this site, including the now famous Bad Case of Drillium post. Here is a picture of Bruce’s 22 lb 3 oz Catrike, which started life weighing 35 lbs! I like it! Looks like a seat, a chain, and cables will finish it. Plus helium in the tubing.
