I've been waiting for products like this to emerge...

I remember years ago there was a push for pedal-powered ultra-light flight, with cash awards for those whose pedal-powered craft could meet certain benchmarks. The problem at that time was that even with geared pedal power similar to that used in good bikes, it still took an incredibly powerful person to supply the pedal power.

But now that E-bikes are common and the motors and batteries are being mass-produced (bringing the prices down and the capability up) such vehicles are sure to be revisited by engineers. E-bike technology solves the problem of a human having to supply the necessary torque to move weight a certain distance.

The combination of good gearing and light weight battery powered electric motors opens a lot of doors. Its interesting to watch technology progress.

Thanks for posting such an interesting video, Jim.
