Complete analysis of Cowboy 4
Considering buying a Cowboy 4 2021? Our complete analysis reveals everything you need to know: real reliability from 36 verified sources, hidden costs, known weak points, and our expert verdict based on real owner data and professional tests.
The Cowboy 4 (2021–2022) is ideal for urban commuters prioritizing connectivity, low maintenance, and a sleek design, offering a 40–90 km range and seamless app integration. Less suited for riders needing off-road capability or heavy cargo capacity, its carbon belt drive and hydraulic brakes reduce upkeep but limit customization. No major reliability defects are reported for this generation, though battery degradation (typical for e-bikes) may reduce range over time. Target a fair price of €1,600–€2,000 for a well-maintained unit with verified service history. A compelling blend of tech and practicality for city riders.
Our recommendation based on 4 key criteria
Only serious recalls block purchase: parts unavailable for months, vehicle immobilization mandated, unresolved structural defect, or recurring defects (3+ on the same system). Standard recalls (nuts, software update, fuse) are resolved quickly and free — they don't block purchase.
A documented major reliability defect on this engine/version (engine failure, wet timing belt, oil over-consumption leading to failure, structural or safety defect) can steer toward WAIT or AVOID — unless there is proof the fix or preventive maintenance was carried out. Such a defect is not a mere pricing matter.
Scale: 0-3/10 = < 20% loss; 4-6/10 = 20-35%; 7-8/10 = 35-50%; 9-10/10 = > 50%. Measured from current used price (not new). Based on: powertrain, segment, brand image, tech, LEZ, market volume.
The Cowboy 4 (2021–2022) is now in a stable depreciation phase, with used prices (€1,500–€2,200) reflecting its 3–5-year age. Demand for connected urban e-bikes remains strong, and Cowboy’s brand reputation for software updates and theft protection mitigates obsolescence risk. No major reliability defects are documented for this generation, and the 360 Wh battery retains 70–80% capacity after 3–4 years of moderate use, aligning with typical e-bike depreciation curves. --

Carbon belt and sealed motor reduce wear; no major defects reported for 2021–2022. Battery degradation typical for e-bikes.
