It may not be exactly the invisible bike, but designer Joey Ruiter came pretty close with his "Moto Undone:"
At jruiter I.D. we want to re-set the definition of a motorbike stripping away historical attributes that make them so great. It’s hard to image a motorcycle without fancy paint, overpowered motors, exposed mechanical genius, and sweet exhaust tones.
Moto undone is pure generic transportation and by motorbike category definition it isn’t very cool.
There motorbike references are small and when someone is riding they are all you see. The bike almost disappears. The rider just floats along the streets silently.
Powered by a 1000w 48v electric hub motor, moto undone has a range of 90 miles or about 3 hours. All gauges and riding information, like speed and gps, is displayed through smart phones by downloadable apps.
