Just for comparison, that's a 2.27 ratio. My Class 1 Specialized mountain bike with a similar Brose motor has 9 gears, ranging from 2.9 to 0.7.
Even though I live in a hilly area and my knees are shot, I very rarely use the lowest gear on my bike, and even the second lowest isn't very common. So it sounds like that ratio could be fine for me when taking off and going uphill.
But on level ground I'm normally in 7th gear, and as soon as I start downhill I am always in 9th and wishing I had more gears. I have a hard time imagining the speed your legs would have to be spinning to go 20mph or more with a gear ratio 3x higher.
But these are just numbers, and could be wrong. I haven't ridden the Mosh. A post from someone that has ridden it would be much more helpful!
