In general e-bikes have a mass of around 30kg and cars have a mass of around 1500kg. So it will use ~1/50th of the raw materials of a car.
I would not say that using 1/50th of the raw materials that a car does is “considerable”.
There is even an argument to be made that an e-bike is more efficient than a pedal power bike because energy is lost when people transform chemical energy (food) to kinetic energy (pedalling).
“considerable” compared to what though?

Also the bicycle is the literally the most efficient form of transport (even more than walking).
