25 mph on a flat indefinitely? BS. Not even with a tail wind.
You are right, of course. there is no such thing as indefinitely.
In real terms, in my present condition, I can go about two hours nonstop at around 25 mph if it is flat. Next year, I’ll be able to go longer. Unfortunately, tail winds don’t help me much cause my velomobile is aerodynamic back to front too.
Wasn’t trying to BS anybody, I just wasn’t being exact. I’ll do better.
