We have both a mid-step through and a high-step Gazelle ebike. I don't regret getting the high step due to the extra strength and rigidity it provides (I am 6'6" and 275lbs - big guy). My wife is also tall but wanted the low-step but it was not available, so she got the mid-step. I like both, and if I was lot smaller and didn't need the strength of a diamond frame, I would have opted for the mid-step through or possibly the low-step through. I'm 67 and don't have any issues getting a leg over the top rail now, but in 3-5yrs, who knows. Which leads me to another issue. Too often, when starting out, I struggle a bit to get my other foot solidly planted on the left pedal. This can feel a bit twitchy in the middle of an intersection. But I'm not sure how to deal with that, except get used to it.
Also, note that there are different ways to mount a high-step bike that you might find easier.
- I like to place my left foot on the left pedal, push off with my right foot, and then swing my right leg over the bike. Starting from pedal height vs from the ground is a lot easier for me. This also overcomes most issues I might have had with items on the back of the bike, as one is much higher when swinging their leg over when standing on the pedals. I started doing this when I was a kid riding my older brother's bike, so it is natural for me.
- You could also lay the bike over (toward you) and swing your leg over. This works well as long as you don't have much weight in a trunk bag that sits high on the back rack, which can cause the front wheel to come off the ground at times. Mostly not an issue, but I have had this happen a couple of times when I had some heavy items in the trunk bag.
Hope that's helpful.
