Why Don't Electric Cars Have Multi-Gear Transmissions?
One of the biggest differences between electric cars and their conventional counterparts has to do with the drivetrain. An internal combustion vehicle has a multi-speed gearbox with numerous ratios; nearly every electric car has a single-speed transmission.
Implicitly, this makes sense. An electric motor delivers its maximum torque at zero RPM. Unlike an internal combustion engine, it doesn't need a system to disconnect it from the drivetrain to allow it to idle while the vehicle is stopped. But there's a more in-depth explanation to be had here, and it's fascinating.

Most electric cars have a single gear ratio. You probably understand the basic reasons for this, but the math is still super fascinating.
