Fun fact: 130,000,000 E bikes are expected to be sold between 2020 and 2023 (source 'Delotitte'). There are already uncountable millions of E-bikes and scooters on the roads/footpaths of the world, and given the lifecycle of their batteries is circa 6 years, which has encompassed their mass introduction, then add that battery replacement figure to Delotitte's 130,000,000 coming (new) E-bikes - well that's a lot of lithium (circa > 300,000,000 batteries. This does not count scooter batteries. And yes, those batteries are small compared to cars, but you'd be surprised at how the 'small' adds up to the 'big.'
