Cowboy 3 electric bike review: Design and Ride The Cowboy 3 design is a clever optical illusion. Its sleek exterior doesn’t hint at the sheer amount of technology crammed beneath the saddle. From automatic crash detection to location tracking, there are a lot of smarts included in this electric bike. Cowboy integrates the lights into the frame design too, so you can never accidentally leave your bike lights at home. This approach also means you’ll never have to worry about charging your lights as both front and rear are powered by the 360Wh battery pack. That’s useful, but pretty standard for an electric bike in this price range. However, the team at Cowboy has gone a step further and programmed the rear light to flash when it detects that you’re slowing down. This is designed to attract attention and make you more visible as you approach a junction. It’s a really clever idea and works a charm straight out of the box — don’t worry, you won’t have to hunt around in the settings to enable it.
