My lugage bag (+ lock and rainponcho) on the rear rack is nearly 3Kg; making a strong and cheap construction of 3Kg, that's unrealistic. The project is made with materials you can get everywhere. Maybe the aluminium has to change for steelpipes in some regions. Not many City-people have space...

This is a project concerning most of us bikers. I just posted this on the Instructables site. See: http://www.instructables.com/id/How-I-carry-a-workshop-on-the-rear-rack-of-my-bicy/ The opening text is: This, all in one workbench, worktable and toolbox is born out of necessity, to drive...

My video show's for sure a low-tech solution for passing the (still)waters. Yesterday I saw a show on German TV. They showed a High-Tech amphibious bike. I made a screener video you can see here (german spoken): https://vimeo.com/42285316

Only in the water is this Amphi-bike electric propelled by a cordless drill "inboard motor". Outside the water it's just a normal bike with all the stuff on board to go amphi. The aim of this project is to show an amphibious bicycle from stuff you can find at your local hardware store. I use...

It is such a pleasure to see that on the Cordless Canoe Chalenge (the 3 C's) there where very original design's and solutions AND extremely high speed boats AND there was a lot of fun. Yes Jeremy, a typical British affair, that's wat we like so much here on the continent.

Thanks for your warm welcome on this board. Also thanks for your appreciation of the trolling motor. I am still working on it; changing the drill and the propellor, for optimalising the thrust. A competition for drill powered canoe's, that's unbelievable. What is it's goal, speed, originality...

The basic idea of this trolling motor is the multi functionality of the cordless drill. Is the power of a battery drill enough to drive a trolling boat on still waters? The answer is yes. I made the trolling motor from wood and some other parts in a Clear design with Clean materials and Cheap...
