Electric cars are lagging in Australia, but we're right behind e-bikes and scooters. Rental schemes abound in larger cities, and the sight of a person in work clothes zooming along on a scooter or bike is commonplace. Unlike an electric car, bikes and scooters are so simple you can build and fix them yourself. An electric scooter off the shelf costs over $500, bikes can be several thousand, and mobility aids and wheelchairs can be tens of thousands. And then you might be left with a doorstop the first time they break down. So lets look at how to assemble your own from parts -- the five key parts of a micromobility vehicle are the motor, the frame , the motor, the battery, the battery management computer and the speed controller. Those last four all have open source options that lead the field.
