A handlebar type that is often overlooked but is the most ergonomic of all, is the North Road.
I have variants of these bars on 4 of the family bikes - my current two visitor bikes, the new Raven Tour Step Through small visitor bike I just built up and my wife's bike.
The bars on my wife's bike and the new visitor bike are "BLB FUBAR HANDLEBAR" in 480 mm width, the straight ends on these are just long enough to fit a Nexus 8 Shimano twist grip shifter, brake levers and grips for small hands. Both these bikes are set up for a
very upright riding position.
http://www.fixedland.com/BLB-FUBAR-HANDLEBARMy large visitor bike has a similar bar, but a tad wider and with slightly longer straight ends. This extra length enabled me to fit an Alfine 8 Shimano Rapidfire shifter (which I prefer over the twist grip) and full length grips to suit large hands. Due to the long frame, my riding position on this bike is not upright, but more relaxed than on my drop bar bikes, I would say between the "relaxed" and "fairly relaxed" positions shown in the Thorn Mega Brochure. I can ride this bike comfortably for long distances, although I miss the drop bar options of changing hand position and the low "down on the drops" position for headwinds.
Two of my drop bar bikes have "traditional" drop bars, my 2016 Raven Sport Tour has compact drops, which I now prefer. I will probably convert my Raven Tour heavy touring bike to compact drops, but my 1977 light derailleur tourer will have to keep the traditional bars as compacts don't seem to exist in the 25.4 centre bulge size that fits old quill stems.
I have straight bars with bar ends on two of my bikes, my old 650B utility bike now used mainly for survey work and my Raven Tour utility bike used for shopping and other urban trips. The Raven Tour utility bike will probably end up with either compact drop bars or some variant of North Road bars.
