The 20kg bike would accelerate roughly twice as quickly as the 40kg bike. Accelerating super quickly is not safe.

A motorcycle accelerating at full speed without a rider is very dangerous no matter how many horsepower. I don't think that should be the test method.

Also twice the power doesn't give you twice the acceleration as you pick up speed. Each mph takes more energy than the last.

On the other hand, getting hit by a 20kg bike would hurt a lot less than a 40kg bike at the same speed.
