My Pedal Assist Bike

My neighbor's kid had an electric motorcycle that has been sitting idle in the backyard for awhile. The bike ended its life after the speed controller gave up. The cost of the part could not justify the  use of it. One thing is he already outgrown the toy. I decided to give it another life in a different form.

 Trying to salvage the main frame. 

 Added a small basket to hold the battery.

 I used two swivel casters, one caster I have to bore the middle part.

There you go as it is almost completed.

HandCrank FlashLight

I wonder how this little handcrank flashlight works. They say its cheap and simply made. Sure enough we have the idea on how it works, but inside that plastic case we don't really know how it ticks.

This little wonder sealed by the plastic case. Picture taken on each sides.

Took it apart, picture in opposite sides with main parts showing the crank, gear, light assembly.
