"Physical activity gains from active travel are similar in e-bikers and cyclists."
E-bikes make people who aren't fit enough to ride muscle powered bikes to start doing moderate exercise on local trips they would used cars for before.
How can they be the same? One requires much more physical effort. That sounds like junk science. Perhaps they are similar type of gain but the difference in actual result must be a canyon wide.
