Gears not the gps most likely.
If it's like the one I had it's got a 48 tooth big ring and a 13 or 14 rear cog so that's about the speed you'd spin out at around 100 rpm. It's actually got a MTB drive train. If I recall correctly that's why I looked for a freewheel with a 12 or 11 tooth cog when it was time to replace it. Or it was when I upgraded the wheel to a freehub with 11-26 cassette.
