    A Guide for Buying LED's on E Bay ---- Part TWO

    I know this is a DIY site, but I bought 3 of these - all have worked great for years.; https://www.amazon.com/MicroSolar-Digitally-Adjustable-Vertically-Horizontally/dp/B00D1JCW30/ref=sr_1_1?ie=UTF8&qid=1468337906&sr=8-1&keywords=microsolar+126+led they run off of a simple solar panel, and take 5 min to install.

Lastly, just like folks put chains on snow tires in the Winter for traction, I'm sure you put something similar on your rear tires that have small fins, like you'd find on riverboat paddles (or paddle boats) Lastly, if you wanted a challenge, rig up a gear wheel that uses the friction of the rear tire to run a propeller on the back. If you did that, you would not need to keep the rear tire in the water. Or you could do both the chain (paddle fins) and propeller. Inflatable innertubes might be another good addition to the outside of the pontoons. And lastly for ocean biking - small outrigger pontoons, like you'd find on...see more »You need a 'daggar boards' for the front pontoons - or at least a fin, like you'd find on the back of a surf board.

Good luck with all these ideas.
