In our case it was a multi-speed bike, but to simplify we decided to always stay on the maximum speed (largest chainring with smallest sprocket). We kept the sprockets and chainrings, but we disassembled the chainring shifting mechanism and cut the shift cable that changes the sprocket. *Attach the frame of the bike to the ground. In our case, we attached the handlebars of the bike's base into the saddle tube to give lateral stability, and a frame tube was embedded in a tube attached to the ground. You will need to adapt this according to the available parts and the type of bicycle. *Install a comfortable seat at a appropriate distance from the pedals. We opted for a seat with a backrest instead of a saddle, because the cyclist's pelvis does not need to move in the same way as regular cycling. The distance between the pedal and the seat should allow the leg to fully extend at the furthest part of the pedal turn, and the cyclist's hands must be able to easily handle the tools that will be driven by the crankset (blender, sewing machine, drill, etc). handle the tools that will be driven by the crankset (blender, sewing machine, drill, etc). +

Transmission pulley 1 will be driven by a belt connected to the bike wheel, and transmission pulley 2 will power the desired tool with a second belt. *Secure the hub on a block of wood with the eye straps. This block of wood will later be attached to the table. f wood will later be attached to the table. +

In our case, the table is 1 meter above the ground. Its structure is made of battens and the worktop is made of pallet boards. Attach it securely to the ground. *A 2 cm gap between two pallet boards allows the belt that connects the wheel to the transmission pulley 1 to pass through. ul that the cyclist's knees do not touch the table while pedaling.</div> </div> +
- Countless tools can be powered by the cran … Countless tools can be powered by the crankset. Here are the ones we are currently using: *Fruit juice blender *Column drill to drill and grind. It can also be used as a lathe *Sewing machine *Grain mill *Electric generator to power Peltier units and charge batteries. Depending on the tools, several types of connection are possible: *Direct belt with gear shift (see column drill) *Belt in 8-shape, to reverse the direction of rotation (see sewing machine) *Twisted belt, to go from a horizontal axis rotation to a vertical axis rotation (see blender) *Belt with corner return (see mill) *Via the crankset chain. For our electric generator, since its optimal rotation speed is much slower than the other tools, we preferred to attach it to the frame of the bike and power it directly via the crankset chain. This allows you to generate electricity at the same time as you are powering another tool. rew wedges into the table to secure each tool in the right position. Our blender door is mounted on a hinge and can be folded down to install the sewing machine.</div> </div>
