My 4'-11" tall sweetheart with severe knee arthritis did not want to hop off the saddle at every stop. She insisted I find a bike that allow her to put her feet on the ground while sitting at a standstill on the bike. This measurement on Rad Step-Thru bikes is not found anywhere. Even Rad Power Bike representatives cannot tell you the answer. They only know the measurement from minimum saddle height to the lowest pedal (a more meaningful measurement for anatomically correct bike riding).

So, for all you short riders who still want know what the minimum seat height to the ground is for whatever reason, I offer these pictures of measurements I took:

The RadCity Step-Thru has the shortest minimum seat height to the ground at 28 3/4"
The RadMini Step-Thru measures 29 1/2" minimum seat height to the ground, making it 3/4" taller from the ground than the RadCity ST.
The RadRunner was significantly higher than these other two and my baby could not sit on it at a standstill, so I didn't get a measurement.

Although it may seem that shorter tires make the minimum seat height shorter to the ground, they really do not when it comes to bikes of different frame design.
 
The RadRover Step-Thru was the tallest bike they brought out (for me to test ride). The factory saddle at minimum height measures 33 3/16" to the ground.

FYI: my RadRover5 equipped with the Bikeroo Oversized Comfort saddle, the minimum seat height to the ground is 33 5/8". I did not measure it with the factory saddle, but it is said that the RadRover Step-Thru is the same frame as the RadRover5 except for the step-thru part of the frame.

Yeah, I realize seat height to the ground is the least important measurement because the seat will most likely raised up in order to achieve an anatomically correct position when peddling. But there are those who for whatever reason insist on reaching the ground at stops while remaining in the saddle (a convenience that taller riders take for granted).  This is only an FYI post to offer geometry measurements not found anywhere else.

Oh I had not noticed that one. It's cool that you can set it with your iPhone.

I will have two ebikes (Radrover4 and RadCity Step-Thru 3) so will be charging at the same time.  I put this one in my cart:

I cringed everytime I would go a day and realize that I did not unplug the bike charger! I think this will solve that problem.

Thank you for the response.

I keep forgetting to unplug my battery charger!   So I want to buy an electrical outlet countdown timer.  There are plenty on Amazon, but with mixed reviews. Does anyone have a brand recommendation?

What is the measurement of the RadMini Step-Thru from the lowest seat position to the ground?

All I need is a simple objective measurement.  Only an owner of a RadMini Step-Thru can answer this.

Regarding the "lack of torque" there is a torque rating of 80 in the RadRover motor and a rating of 40 in the RadCity motor. Surprisingly, that makes NO significant difference between the RadRover and the RadCity Step-Thru in acceleration time from 0-20. In one run, the RadCity beat the RadRover by a split second. There is only a negligible difference in hill climbing favoring RadRover. This YouTube video demonstrates this performance comparison well:  https://www.youtube.com/watch?v=qmn8xidOjLo  I will try to post a snap shot of the video results on this post. In sum, the large gap between torque ratings of 80 vs 40 makes little difference in actual performance from 0-20 mph. [/img][/img]
