Personally I like a low of at least 1:1, often lower for the bikes required to carry loads or perform cycling modes other than racing about. Even the racer-about has a 1:1 (30 ring, 30 sprocket) although it also has a top gear of 1:3.7 (52 ring, 14 sprocket). Even so, it manages to pass any number of MAMILy lads heaving on a 53X11, often when I'm using it's middle 39 toof ring.
There are signs that lower gearing is beginning to be offered again albeit still accompanied by ludicrous top gears now involving 10-toof sprockets. Of course, many frames with braze-on front mech fittings will not allow the front mech to descend far enough to work well with any chain ring below 50 toofs. And the front mechs often lack the correct cage curve for smaller rings. Still, one may always buy a new "gravel bike" on to which the smaller chainsets, front mechs et al will fit; or an old fashioned frame with a round seat tube taking a band-on front mech fitting.
Yes, the new low gears will often need the consumer to also consume a lot of other "new, improved" stuff. Wot a surprise.
But one can always shop at Spa Cycles............

To be clear, Shimano's own e-bike system uses chainrings between 34t and and 47t, and only one chainring. The 50/34 stuff using Shimano components is not a 'Shimano e-bike', it's a bike using standard Shimano (non e-bike) components.

mattsccm wrote:Whilst this slight increase in top gear is rather pointless to many , 52x13 was the norm when I started riding with a club it must be said that looking for lower gears overall isn't a trend for all older riders. Many that I know keep to their older systems and gears with a 42 inner being fine and a 28 at the back being thought of as more than low enough. 4 decades ago that would have been considered an old mans and beginners gear and I for example used my TT wheels much of the time. A 13-17 block did everything apart from loaded touring.
I suspect the trend for much lower gears has come from mountain biking and the huge number of cyclists who started in this way. I bet my club gravel/easy MTB ride this evening will be split. Of those on CX type bikes the roadies will be using a 50/34 with at most a 42 biggest on the back and the MTBers or those who came that way will be on a single chain ring with a 36 or 42 big at the back. Hmmm
I'd love a 11 speed cassette that went from 13 to 30 with no silly gaps at the big end.

Not entirely the case with all the road racey style e-bikes. Many of those employing the Fazua motor system, for example, have a special e-bike chainset and gearbox from FSA that is (in my view) foolishly provided as a 50/34. If one needs an e-bike to ride about, even if it is in racey configuration (which has advantages other than being more speedy) one does not need high gears, so a 42/27 MTB-style double might have been better, especially with its 11-34 cassette..

Not sure what you are disagreeing with here; Fazua is not Shimano, and neither is FSA. The bike may however be marketed as 'Shimano Ultegra' based on its derailleur & shifters.
A 'Shimano e-bike' uses Shimano's Steps mid-drive motor.

A triple is ideal as I'm generally on the triple middle ring most of the time. Where as I'm on inner / small or outer / big on a 50/34....

That's the thing that baffles me. What are laughingly described now as "compact" chainsets are nothing of the kind. For those who don't want triples, something like the above would be sensible at least as an option, but it's relatively hard to get.
