I thought it was a 2:1 ratio. Either way, I did notice the small chain ring and I recognize the added wear to that chain ring and chain as well as that idler gear.
I would love to have the latest and greatest and that is one reason I have been slow to jump into the ebike market.....at this point, we are almost guaranteed that whatever we buy will be outdated during the next model year.
So basically, what I am getting from this thread and other research is that the Haibike FullSeven is a good bike with no obvious or know mechanical QC issues but it is very clearly, last year's technology...or the years before.
Looks like if I pull the trigger, I will be saving money but picking up a bit more maintenance with chain ring and probably idler gear replacements. Before you brought this up I happened across a video showing how that is done and it is pretty simple. But I need to buy the special socket. I believe my current crank arm puller will work.
One good thing is that Bosch is local to me (So Cal) and they produce and sell a kit to replace the motor bearings when necessary after the two year warranty.
A lot to think about. A lot of different bikes, all with different components with a variety of motors - Yamaha, Shimano, Bosch etc.......
