That’s due to the materials, cooling, & intended (decades of continuous, low-vibration, & safe industrial?) use - the one you linked has a cast iron frame, which is prob the majority of those 200kg.
But I def don’t know anything about electric motors 120 years ago, what was available, how the rich kids did their hobbies, etc.
And I do agree that the 250 estimate might not be too much - however that means that the car was unbalanced af & the driver had to sit on the opposite side of the (initially one) electric motor to provide counterbalance (instead of the motor just being mounted in the centre of the car) nvm, it had two.
250 for the engine is way too much.
A typical 22kw electric engine today weighs about 200kg, so I don’t think 250kg is too much

Here is a random example (bcs there is a table included with power & weight) under 100kg that looks about the same: globalsources.com/permanent-magnet-motor_1210699575f.htm.
