In addition to having top-of-the-line components and a hydro-formed 7005 aluminum frame, all KETTLER electric bikes are equipped with the newest Panasonic manganese lithium ion rechargeable battery system, which makes riding more pleasurable. This electric bicycle battery system has a total range of more than 50 miles per charged battery (12Ah battery). Each KETTLER electric bicycle, or e-bike, also comes equipped with a security package which includes a solid frame lock integrated securely into the frame with the same key locking both the frame lock and battery securely. Just like all KETTLER bicycles, the sturdy e-bike frames are put through a 3-step powder coating process and still assembled in our own factories in Germany where they've been hand-built for more than 40 years. If you are considering hybrid bikes to make your daily rides easier or a city bike to help with your commute, consider a KETTLER bicycle.
