Multiuse Bike Machine - Innovate or die competition

www.mayapedal.org

This is my multiuse bike machine.
Its functions include:
-knife sharpener, to maintain farming equipment
-grinder, for grinding coffee, grain, spices, or to make animal feed
-corn degrainer to simplify and accelerate a necessary but time consuming task in processing corn
-electric generator for off the grid lighting
-blender to improve nutrition and add enable home based micro industry
-water pump, capable of moving 5 gallons per minute

The tools are mounted on tables which attach to a simple 3 point mounting system. The tool tables can be switched easily using only one tool. Changing attachments usually takes under 5 minutes.

The design is simple yet versatile and I am still working on developing more attachments.

Similar pedal powered machines have proved to be very useful to subsistence farmers in rural Guatemala. My design combines these 6 machines into one simple design, to streamline production and lower costs. While it is unlikely any one user will want all 6 tools, the machine provides more utility at a lower cost.

All of the parts are locally available and it can be built and maintained with a minimal number of tools.


Note: Please pardon the terrible video editing, it's my first attempt and embarrassingly bad.

howdy, what a great idea to combine all the machines into one! I´´m at Maya Pedal now do you know if that machine is still kicking around? how long did you stay at mp? did you make any plans for this?

@amike6301

Sadly Carlos took the machine apart when he needed parts. Last time I was there, the frame was on the roof and flywheel was still around (just look for the wheel with the cement filled tire).

I never made instructions but the only difficult part was the chain drive.

Have you got the butter-churning option available for sale? What about a blender and an electric generator??

[astromilio]

This machine is just a prototype, it is not for sale, and probably never will be. Mayapedal makes many similar machines but they serve local communities in Guatemala. We don't have any butter churning machines. Sorry I can't be of more help.

I am really amazed: ideas like this one are what we need to reduce our use of energy. GREAT WORK!!

[zecnobot]

I want one of these!

It probably would have worked if he had frozen the freewheeler and used one outer sprocket for the crank and an inner sprocket for the work table. Do without the derailler altogether.

[temple26797]

A major drawback to it is no handlebars. He loses at least 1/3 of his power output.  He was aiming it downhill in the video for more power.

The work chain uses those little derailler sprockets for power transmission, which they were never meant to handle. That was probably the fatal flaw to the whole thing.

Wow great idea. : )

[corduroy99]

yeah pero pa ke mi súchiles si no dejó planos y destruyeron la máquina =-(

Así paquete cuetes!Thumbs down

This is why documentation is so important. There are lots of " gear heads " out there that could build something like this themselves with no " instructions ", but there are a lot of others that would love to build something just like this, that are not mechanicaly inclined, and need some instructional guidence.

This is awesome! I am going to build one to power my grow lights!

hello

Are any instructions available for building this bike and for making the corn degrainer?

Thanks
