After I've bought my strida folding bicycle, one of the first things I've done was to check out instructables.com for any strida related projects. And quite astonished to see that there wasn't any. So I've planned to make an instructable that can be used on my (and also others') strida. Though my expertise is electronical engineering and solar lighting systems, I've chosen to build a propel light for the strida. The improvement to the other propel lights around the web is to use solar power and to create a totally independent light system that "lives" inside the strida wheel. There is no wires to the outside world and no need to charge either.
