E-bike startup Cowboy has launched the Cowboy 4, its newest generation of urban electric bikes. The C4 is basically an upgrade on the previous version 3, while the ‘C4 ST’ is a step-through model which the company is predicting will appeal to young people used to city bikes. Cowboy has raised $46.1M in venture capital and largely extent competes with VanMoof (which raised $61.1M) and Furo Systems (£750K) to a lesser extent.
