See the Cowboy 4 ST on the streets
A reliable prediction
With Cowboy, you'll always have a reliable source of power when you're on the road.
The app uses predictive technology to calculate your remaining autonomy based on your riding behaviour. Whether you're usually carrying an extra heavy load, requiring more power from the motor and battery, or cycling in tough road conditions, you'll always know about how much power you have to get to where you're going and back.
And if ever we detect you'll soon run out of juice or won't have enough for the return trip, we'll notify you it's about time to recharge.
Battery level estimation
With Cowboy, you're in charge. We keep you informed of your current battery level before, during and after each ride so you can always plan ahead.
Through predictive technology in the app, we show you how much you'll have left at the end of the ride. If you'll run out of power soon, we'll notify you that it's time to recharge. Then simply remove the battery with a turn of a key and carry it inside. It weighs only 2.4 kg and charges fully in 3.5 hours.
With proper care of your battery, you'll get the most out of its expected range so you can roam further. It's common for lithium ion batteries to reach a lower range in different conditions, such as during cold weather when it can temporarily lose up to 10km of autonomy, or in more challenging terrain like hilly roads or start-and-stop traffic.
