Hi,

Is it possible to get a bike with a Bosch Active 250w system and later on upgrade to a Bosch Performance CX 250w system or is that basically a whole new bike?

In other words, are they interchangable units?

Many thanks,
 

Sherman

I guess same year models could be interchangable. But upgrade is impossible as you cannot get drive units anywhere. So new bike is the answer.
