Cowboy’s latest 4 and 4ST e-bikes are being treated to a free software update today that adds a new adaptive power feature meant to automatically overcome any resistance as it occurs, be it a hill, blast of wind, or kid in a baby seat. Cowboy is also adding three new color options for its 4ST step-through model.

According to Cowboy, its proprietary software feature works at low and high speeds and doesn’t require any gear changes — good, because the company only sells belt-driven single-speed e-bikes. With the new update, Cowboy says the motor will provide the extra power “seamlessly” whenever a C4 or C4ST senses any extra resistance in the environment.

That all sounds good, but I remain skeptical that it can flatten especially steep inclines. Cowboy’s small hub motor is rated for 45Nm of torque, which isn’t a lot. VanMoof — Cowboy’s chief European rival — provides 68Nm of torque to its new A5/S5 e-bikes, by comparison. But VanMoof also relies upon a boost button for a less seamless experience overall. Fortunately, Cowboy lets you book a test ride in 11 countries, including the US, UK, and major cycling cities around Europe to try it out for yourself. 

Cowboy’s also announcing that the 4ST step-thru model is now available in lavender, fig (peachy-pink), and clay (reddy-pink), if the existing sand (off-white) and black hues aren’t to your liking.
