FOR EBIKE SYSTEM 2 ONLY (OVAL PLUG): This charger features the classic round plug connector and is specifically designed for the Bosch eBike System 2 (models from approx. 2014-2021). ⚠️ CRITICAL: This is NOT for the newer “Smart System” (BES3), which uses a different, round -shaped plug. Please verify your bike’s charging port before ordering to guarantee compatibility.
THE IDEAL ALL-AROUND CHARGER: Offering the perfect balance of charging speed and size, the 4A Standard Charger powers up your battery significantly faster than the 2A travel charger. It’s the ideal choice for daily riders, charging a 500Wh battery to 100% in approximately 4.5 hours.
BROAD SYSTEM 2 COMPATIBILITY: Fully tested for compatibility with the entire Bosch eBike System 2 family, including Active Line, Active Line Plus, Performance Line, and Performance Line CX motors. It works flawlessly with all BES2 PowerPack (both frame and rack versions) and PowerTube batteries that use the oval charging port.
PERFECT REPLACEMENT OR PRIMARY CHARGER: Whether your original charger was lost, damaged, or you bought a used bike without one, this adapter serves as a reliable, high-performance replacement. It functions identically to the original Bosch BCS220 model, ensuring dependable performance.
BUILT FOR SAFETY & DURABILITY: Engineered with multiple safety protections, including safeguards against over-voltage, over-heating, and short-circuiting. You can charge with confidence, knowing our adapter is designed to protect the long-term health of your valuable eBike battery.
