I just love this little thing. This is (reputed to be) the “World’s Smallest Electric Motorcycle”, at 12″ high and 18″ long. 12mph top speed… and 4kg (8.8lbs). The only other specs I have are that it can haul a 62kg person for 15 minutes at a speed of 15km/hr.
It looks like a small AGM scooter battery and one of those little Currie motors, but that’s just a stab.
As far as the fabrication, I have that it is “Some parts like frame, handlebar, and some parts fabricated, some parts from cycle and some from e-bikes”. See more of Santosh’s work here: SantoshBikes.
Is it in fact the World’s Smallest Electric Motorcycle? Apparently a Mr Ripley thinks so.
