The most beautiful thing to me about e-biking is the weight:load ratio. A 30kg bike carries 3 humans totalling 150kg. 5 times its own weight. We'll routinely whizz by 1600kg Range Rovers, typically carrying one adult, 0.05 times their own weight.
And it's not even like-for-like. Within a 25km radius in Dublin, e-biking is almost always faster.
