Explanation of different specifications?

[SarahMary]

I am looking at an E bike an Agattu i360 harmony. 26 inch wheel 2015 secondhand.

The other one is the new Agattu 3 Dynamic 26 inch wheel

I don’t understand the different specifications between the two. I really need power to get me up steep hills. The harmony when I tried it out doesn’t seem to engage only up to 1 bar of power so I think somehow something is not connected. Any help would be gratefully received.

Due to many problems covered in other threads, most people on here would advise against bikes with the Kalkhoff Impulse motor. The new Agattu 3 is available with the Bosch motor (model 3B) and would be a safer bet.

As Jonah has mentioned, the Kalkhoff Agattu Premium i360 Harmony has the Impulse 2.0 motor which is notorious for having problems. Avoid like the plague!

You may wish to read post #12 on here (and elsewhere in the Pedelecs archives) which describes the problems with the Impulse 2.0 motor:

The Agattu 3.B Dynamic has the Bosch Active Line Plus (ALP) motor which receives very positive feedback from users on these forums:

How steep are your hills?
