I found an antique bicycle at the downstair yesterday, the spot on a lattice backseat and a headlight power by graphite. Then we could image when there was no street lights and no cars on the road at the time. 

It is interesting, good shape and modern after watching a video of the Tesla Model B e-bike, run at speed, the rear-light design.

If you can't afford a Tesla, you may buy a Tesla model B e-bike first.
