From a TechCrunch online review:
From the outside, the Cowboy e-bike is a sleek bike. It features a seamless triangle-shaped aluminum frame, integrated lights and a low-key Cowboy logo near the saddle. The handlebar is perfectly straight like on a mountain bike. The only sign that this is an e-bike is that the frame is much larger below the saddle.
The e-bike is relatively light at 16kg (35lbs). Most of the weight is at the back of the Cowboy e-bike because of the battery. But an investor in the startup told me that it wasn’t a problem and that he was even able to attach a baby seat at the back.
The two things you’re going to notice quite quickly is that there’s no gear and there’s a rubber and glass fiber belt. Cowboy has opted for an automatic transmission — motor assistance kicks in automatically when you need it the most, such as when you start pedaling, you accelerate or you go uphill.
