Judging by what I encounter in New York City’s bike lanes, urban e-bikes have seemingly reached terminal velocity.
That observation has less to do with legal limits (which they honestly surpassed long ago), and more with what you can realistically control amidst city traffic.

However, on-road velocity is not the only measure of “speed” and maybe not even the most important one for daily commuters.
Which is where a California start-up called Morelle comes in, with a bold new quickness claim that blows others out of the water: the ability to fully charge in 15 minutes or less.
Better battery
For context, most e-bikes fully charge in three to six hours, with a few coming closer to two hours — all of which pales in comparison to Morelle’s sleek and boastful bike, which should roll out early next year.
How exactly are they planning to charge it up in such a short time? By shifting toward a different battery chemistry that’s already caught on with some EVs and consumer electronics.
