Go fast? Get an eBike.

The number of speed describing a bicycle is like the number of speed of gearbox of a car. Not how fast it can go.
Currently, there are no land speed record for folding bike.
The land speed record of bicycle is held by a lady Denise Mueller-Korenek on a mini velo. 183.9km/h

You also require more effort to do same cadence on a 26in than a 20in.

I am just another kedekut old fat geezer… to avoid wasting money, I pay attention to details.

There are 2 common type of hub, the old type which is freewheel which is use for 6,7 and sometimes 8 speed freewheel cassette. The newer one is freehub which are used for 8,9,10,11speed freehub cassette. They are easily distinguished visually.

You need freehub for 9 speed.

Caution, Not all 8speed are freehub. My 2x8speed minivelo is a freewheel setup.

Sora is great. But Microshift will make a even smaller hole in you pocket.

Oval? As long as you are happy.

53/39 ? This you must ask your legs, nobody can answer for them.

Chainring up to 60T are available. Try hunting from BBS . Offline can ask local bicycle shops, very popular with mosquito bikes.

If you cant tell the difference yourself, why bother so much? You are the one cycling or your friends?

Tern got many models with X22, which one are you referring to?

I enjoy my affordable bike very much. Nobody will bother to steal it.

No such thing as ideal in cycling. Tire pressure included.
Pressure higher puncture lesser, bumpy, roll faster.
Pressure lower less bumpy, more puncture, row slower.
Too high pressure will burst your tire or rim.
Too low you get puncture every 2 yard you ride. You get snake bite puncture holes when your pressure is too low.
There, choose the tire pressure which suits you best. Don't even listen to your wife's advise with tire pressure, trust yourself.

For comfortable ride,
1) Pump to the max rated pressure written on the tire. 2)Test ride, 5km
3)if too bumpy reduce 5psi,
4)test ride 5km
5)repeat 3)-4) until you are happy and without puncture ever other day.

For speed,
1) pump to max pressure rating
2) test ride 30km
3) too slow pump 10psi more
4) test ride 30km
5) repeat 3)-4) until you are happy without rim crack and burst tire.

No need compare la, if you want speed, get an ebike. If you want comfort, get an ebike. If you want a good climber get an ebike.
Any bicycle are as good. Not better than a battery bike.
If you want a tiny fold, get a 14" ebike.

This is where Brompton and it's clones shines.

Brompton clone not super expensive, I bought one for under 1k~ just has to wait for them to appear in ads. Or you can get a 10" or 8", some of them can go into a regular backpack or recycle shopping bag.

Mine is Cigna, 3 speed stormy Archer. Very nice for under 5km flat rides . In progress to put battery on this one too.
I dunno why the change but the seller said he is clearing all his Brompton and clones for smaller, lighter , with more gears Trinx 16", can do both long and short rides.

Yes, love your 412!

If you have zero fitness confident, get the ebike to get started in exercise.
If you are already super fit, buy anything that makes you happy.

Where got "lots of spare parts"? A hub motor which consists of 2 bearings, a copper coil, a freewheel clutch, 4 planetary plastic spur gears. A motor controller which you can replace, a lithium ion battery pack, a throttle and 2 break sensing brake handles.
Buy xiaomi ebike if you worry about repairs.
Ebikes involve electricity and cutting edge battery tech. Most lbs can't handle "new" technology… especially they deal with pure mechanical work their whole life. Most ppl just refuse to move out of their comfort zone.
BTW, online buying is for people who has confident to repair their own purchase. Period.
Ebike is the future, like it or not they will dominate the world. It's only a matter of time.
