    Cowboy 4 Review (2023): E-Bike Overview

    One of the most eye-catching bikes you’ll see, the Cowboy 4 features clean, modern lines, head-turning styling, and impeccable attention to detail. Powered by a 250W rear hub motor that puts out 45Nm of torque, the C4 packs plenty of punch for navigating city streets and tackling uphill climbs.

    The C4’s 36V 10Ah lithium-ion battery is integrated neatly into the seat tube of the bike’s lightweight frame for a stealthy appearance that doesn’t scream “e-bike”. The battery offers 44 miles of range on a single charge and it recharges fully in 3.5 hours. 5 LED indicators incorporated into the top tube make it easy to monitor the bike’s battery level, and Cowboy did a wonderful job with cable management, making use of internally routed wiring to add to the bike’s polished look.

    This ride features custom hydraulic disc brakes that deliver excellent stopping power and the low-maintenance Gates carbon belt drive is first-rate.

    The Cowboy 4 is available in three amazing finishes — Black, Sand, and Khaki. Each color is exceptionally well-done and we have a very hard time choosing a favorite.

    The bike features integrated lighting, with a 200-lumen headlight and 50-lumen taillight for improved low-light visibility and nighttime safety. The C4 also allows you to charge your phone wirelessly, and Cowboy’s app is next-level.

    As mentioned, Cowboy is an innovative brand, and the C4 comes standard with advanced features such as crash detection and auto-unlock. There’s also a theft detection system with GPS tracking that’ll help to keep your bike safe.

    Size and Weight

    The Cowboy C4 is a lightweight electric bike, weighing in at only 42 lbs. It has a 309-pound maximum payload capacity and is ideal for riders between 5’6″ and 6’4″. The bike’s total length is 71″ and the seat height can be adjusted from 37″ to 42″.

    Performance and Ride

    The single-speed Cowboy C4 is an excellent choice for cruising city streets and commuting to work or school. The powerful motor provides a smooth, comfortable ride and the smart PAS functionality automatically adjusts to match the rider’s pedaling power and speed.

    The 250-watt rear wheel motor provides plenty of power for daily commutes and the 44-mile range is more than enough for most riders. Additional batteries can be purchased for added range, and they’re quick and easy to swap out.

    Lastly, we want to mention that just like the Cowboy 3 model, the C4’s riding position is a bit more aggressive when compared to the C4 ST step-through frame version with its more upright sitting position. 

    Build Quality

    The Cowboy C4 is a high-end, premium bike, and as you’d expect, the build quality is outstanding. Cowboy has great quality control and the fit, finish, and bundled components do not disappoint.


    A smartly designed ride, the C4 has a streamlined, minimalist appearance that will stop passersby in their tracks. This e-bike definitely gives off a premium vibe and great attention has been given to the smallest details.

    We’re also very pleased with the color options offered by Cowboy and are hard-pressed to pick a winner. The matte finishes are simply beautiful and they contribute to the C4’s smart appearance.

    Included Accessories & Optional Add-ons

    In the box, Cowboy includes an assembly toolkit, reflectors, and two keys for locking the battery into place. While a kickstand and rear rack are not included (a bit disappointing), they can be purchased separately from Cowboy’s online store. 

    Cowboy App

    Cowboy App

    Cowboy’s companion app is extremely well-done, providing riders with an intuitive cockpit that’s loaded with useful functionality and data. This easy-to-use smartphone app downloads firmware updates automatically and includes features like:

    • Anti-theft (with Find My Bike locator and theft alerts)
    • Crash detection feature that instantly notifies your emergency contacts
    • Ride dashboard with GPS tracking and turn-by-turn navigation
    • Digital key with remote lock and unlock
    • Ride statistics and history
    • Real-time air quality mapping
    • Available for iOS and Android in English, German, French, and Dutch

    Warranty & Customer Support

    Cowboy is a brand that takes customer service seriously, and the company stands behind its e-bikes with a generous 2-year warranty. For added peace of mind, Cowboy also throws in a 14-day money-back guarantee to ensure the thorough satisfaction of its customers.

    There are several ways to contact the company, including phone, live chat, and a website contact form. We’ve found Cowboy’s customer support to be very friendly and helpful, with quick response times to questions and a genuine willingness to assist customers.

    An important factor that we take into consideration whenever we’re reviewing an e-bike is the responsiveness of each brand’s customer service department, and Marta from Cowboy sent us a nice reply to our submitted inquiry about a day and a half later…

    One of the most well-designed rides money can buy…

    Rated 5.0 out of 5
    October 13, 2022

    While a lot of bike companies make urban commuter e-bikes, this latest Cowboy model stands out from the pack and is the clear winner in my book. If you’re looking for versatility, the C4 won’t be a great fit as it doesn’t perform well as an all-terrain ride… but if you strictly want to ride the bike on paved surfaces and aren’t bothered at all by the lack of suspension, the Cowboy 4 is quite literally one of the most well-designed rides money can buy.
