Not trying to suggest that this makes an ebike your answer, but an ebike typically moves at ~25kmph (and can be cheaply jigged to go up to 50kmph), so the trip should be 2 hours or less, depending on terrain and all that fun stuff.
Even so, 4 hours of commuting is still too much, and as I said, I’m not trying to argue with you - or tell you how you should be moving yourself around - just looking to correct what appears to be a bad estimate of travel time in your comment.
