This is a brand new motor still in the factory wrapped packaging. Although they are brand new and unused, I have to list them as “for parts” because I have no way of testing each motor. This German made model was used in several high-end bikes such as Kalkhoff, gazelle, focus and univega. This is the impulse 2.0. With three levels of assistance and shift sensor capability. I have several of these motors in brand new condition. If you are interested in more than one feel free to contact me and I can give you a multiple item discount. If you have a bike with one of these motors, this may be a good opportunity to buy a spare as supplies are becoming limited.
