IMO, 28 mph is fine as defined, which is on a path contiguous with a road (might not be the exact definition). My wife and I, old grandparents, easily exceed that going downhill off road. However, my first e-conversion was a 20 mph front hub. It was a blast (thinking of producing another since my daughter absorbed it). I could live with that.
