On my analog road bike, can't ride without the padded shorts. On my ebike which I added the kinekt seat post, don't need the padded shorts. And I have done a 50 mile ride on the new ebike without the padded shorts.
For long distance riding, I can't recommend a suspension seat post enough. It's a world of difference. Personally, I'm using the Redshift Shockstop. Was looking at the Kinekt, but I was considering a Kinekt, but I didn't have enough clearance between the seat and the top of seat tube.
I'd also recommend a suspension stem to @bigcanoe but I don't think there's an easy way to add that to a Lectric XP without completely rethinking the handlebars.
