Many ebikes sport a derailleur hanging out back to giver riders more flexibility than single-speeders. There are exceptions that combine gears with the motor, such as Pinion and Valeo. And now there's another, as Scotland's Intradrive system goes into pilot production.
You will likely have a hard time carrying ebike up a stair when they disregard weight and built with only power in mind.
I agree. These are now small motorcycles. I like it. If only they’d ditch the bike facade, and make them look cool. Style em up.
