I have a bulls cross mover speed bike. it has been a great bike and I put at least 120 miles a week on it usually more. been playing with the front chainring size as it has way too much top speed gearing. even at 34 I am only maybe 90 rpms cadence. I went from a 22t to 20 and even that I am still at 80 rpm at 30 s oI have a 18t to add. having the smaller chainring really makes climbing faster with less assist. when I am at 30 going downhill I am right at coasting speed.
