eBikes are Motorcycles... the "e" is how the motor is powered... and the motor powers the bicycle

simple logic
simple reason

Bicycle + Motor = Motorcycle

smaller motor still a motorcycle
gas motor still a motorcycle
electric motor still a motorcycle
it is the motor on the bicycle that mades this vehicle a motorcycle

so many intelligent people try to argue this notion...
it is simple
it is plain

a small gun is still a gun

I will not pontificate any further
that is a drop the mic moment
