Hi, I have an iZIP E3 Moda with the step-thru medium size. The step thru comes in small and medium and the step over comes in medium and large.
The height from the seat to the ground at maximum is 41.25"
The height from the seat to the ground at minimum is 34.25"
I hope this helps you. For what it is worth, I just got the bike on Black Friday so I only have 35 miles on it. I have over 3500 miles on my previous e-bike (which I still love by the way) which is a Diamondback Lindau.
I know that from what I have seen Court (on this website) really really likes the Brose motors and from what I have seen so far I really like it too.
The problem with my Diamondback Lindau is that it only works really well if I am by myself. It goes the speed it wants to go and it is hard to modulate the speed because it only measures pedal cadence.
The iZIP moda measures torque and feels very much like a normal bicycle and not like an e-bike at all. That is the main reason that I got it so it is easier to go on bike rides with other people. I believe that I may still use my Lindau for commuting to/from work where I am solo as I really do like that bike quite a bit.
Hope this helps,
Rick
