For short trips cowboy is even a good alternative to an electric scooter (which I was considering). When I ride the cowboy I feel more like riding a scooter than a bycicle. It is a big pleasure to ride uphill without almost any effort. In my previous e-bike I had to choose the amount of power to be delivered x1/x2/x3/x4 and I always had to calculate a fair solution between performance and remaining battery charge. Now this issue is "not applicable" = no stress. The battery is light and fast to charge.
