I have some pictures of my install on a RadCity step thru.
I installed one on the front rack and one on the rear rack.

Just finished a test ride to see how far the battery would go.  I had to give up at 60.5 miles, I was done at that point and the bike still had 2 battery bars left.
2019 Rad City Step Thru
Chehalis Western Trail (Olympia, WA) with some side excursions.
Kept it in pedal assist 1 and 2 except for hills where I went to pedal assist 3 and sometimes 4.
There's a video of the ride if anyone is totally bored out of their mind and wants to scrub through it.

Some notable points in the video:
1h 52min 14sec at 20.26 miles I show the battery meter on the bike
3h 44min 00sec at 40.01 miles I show the battery meter on the bike
4h 37min 55sec at 50.01 miles I show the battery meter on the bike
5h 07min 00sec at 55.01 miles I show the battery meter on the bike
5h 37min 55sec at 60.00 miles I show the battery meter on the bike

Thank you,
