Electric vehicles have become an extremely common sight for many people. Whether it’s viewing a shiny new Tesla lower the street, or hopping on a light rail teach or renting an electric scooter to get from that train to your house, EVs are everywhere.
One problem with electrical motors is that due to the speeds of which they rotate, to become useful in most vehicles, they need a gear reduction device. I’d contact it a 
tranny, but generally, these gearboxes only have one gear reduction motor acceleration. This takes the 10,000 rpm from a drive electric motor and reduces the quickness at the wheels while multiplying torque.
What if there have been a electric motor that didn’t have to spin as fast as that to make enough usable power and torque to operate a vehicle a vehicle? If that existed, you could change all sorts of things about electric car design. If you didn’t need a gearbox, you’ll save a good-size chunk of weight and, maybe a lot more crucially, space.
With that space, you could raise the size of your battery power, and with the reduced weight, you would improve all types of things like handling, range and acceleration.
