E-bikes are a breeze to ride with the battery engaged, effectively smoothing out hills and letting you cruise along at speed without breaking a sweat. However, unless you're on a downhill, riding under your own steam is seriously hard work. Their high capacity batteries are seriously weighty, and a mid-range e-bike can easily be twice the weight of a typical unpowered bicycle. If you occasionally want to ride under your own steam, you really need two bikes – and that's where Spanish bike builder Crow Bikes comes in.
Many (though not all) e-bikes have a battery that can be removed for charging, but Crow's bikes allow you to detach the motor as well, drastically cutting the weight and effectively turning them into ordinary unpowered bicycles for occasions when you want to work your own muscles.
