When shopping around, researching ebikes, less is written about gear ratios than motor options. When I got my bike, pedaling topped out at 15 mph, not very satisfying for me. I've upgraded to a 60 tooth ring up front (while the existing 7 speed 11/28 cog remains in the rear), and can now actually pedal at over 20 mph with a cadence of about 60 (my comfort zone). I wound up getting interested in Rize ebikes for this reason (as well as many others), but they feature a 52 tooth chainring with a 11/28 nickel plated cog. You can look all these numbers up on this website.
