I'm not sure why the focus is on the motors. They can be tiny and well hidden, but what about the batteries ? They are bound to be hidden in the hollow tubing.

I'm not sure why the focus is on the motors. They can be tiny and well hidden, but what about the batteries ? They are bound to be hidden in the hollow tubing. Why don't they just require a small hole where they can poke in a stick to verify the tubes are hollow ? A simple weight check would also suffice. The bike has a known legal weight, oh, suddenly its 3 kilos heavier...

> The bike has a known legal weight, oh, suddenly its 3 kilos heavier... Part of the issue is that bikes have a minimum weight, but with modern materials it's quite easy to go below that minimum. So they can cover the added weight of the motor and batteries by cutting elsewhere.

  moreover, it's not rare when the bikes carry additional weight to be UCI-legal in terms of minimum weight.
