replace shredder motor with bike mechanism under table

11/09/2016 at 19:09

hello everyone,

i’m Cas 15 Years old and i’m from the Netherlands(utrecht), and i have a question about replacing the shredder motor for a leg powered bike mechanism.. I have not yet the time and resources to experimentate and make it myself but if someone does have the time and resources please help!!!
just tips are fine as well I will remember them and I will also begin with the design by myself
*I do not mean an entire bike connected to the shredder but only the turning mechanism under the table.

I saw a video on youtube where dave built a shredder which was powered by hand. here is the link: https://www.youtube.com/watch?v=DfEsz9pTh1o (it is in dutch)

@casb
The shredder design is the same one you can find here on the Precious Plastic website, and you can easily connect any bicycle gear mechanism to the shredder, however, you still need to get a speed reductor to convert the bike revolutions into torque, or make your own with a belt pulley system

What do you mean by big one? Diameter? Circumference?

I recommend you the following tool: http://geargenerator.com/
