28 mph on a road bike requires around 400 watts, maybe slightly more. 750 watts would result in speeds in the mid 30s. 40 mph, maybe 1200 watts or so.
Never seen a pro on a heavy upright e bike. If you can identify the bike, as an e bike when it goes by, you are not looking at a 400-watt 28mph bike. An e bike doing 28mph looks very fast to an observer where a car doing the same speed looks slow.
