As Norm said, some exercise and stretching goes a long way to helping my knees and overall happiness.
Also giving up goals and just enjoying the rides more.
one more factor, if the battery starts at 100% and depletes to 0 in 38 miles using the 28 tooth sprocket,
will it also deplete in 38 miles with the 38 tooth sprocket, if your cadence is the same you'll just get there faster?
class 1 ebike, ride first gear only, 2000 ft elevation overall, will it go farther in miles with a 38 tooth front sprocket instead of a 28 tooth sprocket?
