Re: Obviously the solution is....
They already broadly exist in the form of e-bikes (https://en.wikipedia.org/wiki/Electric_bicycle). Even my dump of a town in the arse end of the Netherlands—think Oldham, but with windmills and even more racial tension—has just had a new dedicated e-bike shop open up. It's a growing market, even though the bikes start at a grand a pop compared to a few hundred for a regular beater.
A killer feature of them is that they're basically motorbikes, but they don't have number plates nor does the rider require a driving licence. This may change as more drunk-drivers discover that they're a good way to get back from the pub despite a driving ban. Under English law, if you're still sober enough to keep it upright, it's legal. Drink-cycling is technically illegal in the Netherlands and attracts a fixed penalty, but so are drugs, whores, and bike theft, and look how much that gets enforced in Amsterdam.
Icon because they use lithium batteries.
