is so refreshing on our electric Gravel carbon bike with big 35c Schwalbe road
tires and the new BionX D-500 motor. Single big 52t chainring is all you
need..... if you go at 30mph you can get range of around 40 miles, but
if you back off a bit and just go 25mph or so, which is still plenty
fast, the range increases up to around 50 miles. Bike is almost
completely silent, super smooth, super awesome! Will be sad to sell.....
