Remorques de vélo Pedal powered water pumps, threshers, blenders, tile makers and more What Are Bicimáquinas? Bicimáquinas are pedal-powered machines that assist with a variety of jobs in the home, on the farm, on the road and in small businesses. Each bicimáquina is handmade in our workshop using a combination of old bikes, concrete, wood, and metal. So far, we have developed several original designs that have proven to be both functional and economical. We have produced fact sheets and instructions for the more popular designs. We also have some Sketchup models. Bicycle Mill/Corn Thesher This bicycle machine is adapted to fit a hand powered grinding mill or a corn thresher. The Thresher is used post-harvest and easily degrains 12 to 15 quintales (1 quintal = 100 lbs.) per day and requires only one person to operate the machine. Bicycle Blender A common kitchen blender adapted to a converted bicycle. Bicycle Rope Water Pump The Mobile Water Pump Fits on a bike and can be taken anywhere. Bicycle Nut-Sheller Removes the outer-shell of macademia nuts at 7lbs per minute. Prototypes

Tutorial - Bicycle Bearing Basics - Page 2 of 13 When you are disassembling bicycle bearings, take note of the orientation of the bearings into the cups. Typically, the balls are inserted into the cups with the flat part of the retaining ring facing upwards, but this is not always the case. An obvious indicator of improperly installed bearings is excessive friction. If you place the bearing into the cup and press down on the race, it should turn freely no matter how much pressure you apply. A bearing installed upside down will have a lot of friction and be difficult to turn while pressing down on the moving parts. You can build it yourself from our easy to follow DIY plans!
