I have a Trek hybrid with multiple chainrings 48/36/26 and an 11-32T 9 speed cassette. It's been years and thousands of miles since I last dropped from the 48T during a ride, so for e-bike gearing, I was mostly concerned with having one that was high enough geared in the highest gear since a lot of e-bikes have a small chainring and are lower geared in the top gear, especially mountain bikes, which makes sense for their most intended purpose. With my 700's 45T chainring, I only use the top gear going down hills and have never dropped below second gear going up a steep hill, so it's worked out well and hasn't been range limiting to either extreme for me.The display I got is the same 3, 5, 7, 9, each level adjustable but I think it only goes 5% either way from the preset percentages. Hopefully the controller is capable of doing what the display can do, that I won't know until tomorrow. I looked at the Ride1Up bikes along with many others. No multiple front sprockets on those and most other better quality bikes took those out of the running for me.
For mountain bikes, Ride1Up's Prodigy will have a higher top gear than your traditional single chainring mountain bike. It will have a 44T chainring, 11-34 cassette, and use a Brose motor. Sorry, no throttle.
