Never ridden a bike, but in cars the control is excellent. Way way better than a conventional engine.
In a normal engine the control is 4-5 steps removed from the business part of the engine. You don't actually control the engine, you control some flaps and the end engine has to deal with fuel, sparks, timing etc. all of which is affected by temperature, altitude, moisture etc.
In a motor the engine controller drives the magnetic fields in the coils pretty much directly. There are also no moving parts, so it can adjust thousands of times a second. Night and day better IME with cars.
Engine braking wipes the floor with a piston engine. A 145bhp electric motor can do 145bhp in either direction.

My car has a 'sport' button that makes the throttle really responsive, so much so that if you're used to driving it in normal mode sport actually becomes a bit of a pain.
I don't think I'm ready for an even more responsive engine?
Part of the issue with controlling piston engines is delay and inertia in the system.
When you boot it there's a whole sequence of things which have to happen and there's a whole load of inertia overcome. You also have to fit around all the noise and emissions requirements when you're doing it. Then when you pet off you have all the same problems in the opposite direction.
Electric motors are actually a lot easier to set up cause there's so much less going on.
If you drive a modern EV the 'throttle' is remarkable. I would encourage everyone to try it.
I watched an episode of Vintage Voltage today where they did a Ferrari 308, once I'd got over the horror of it all, I decided I'd actually quite like to have ago. They put a Tesla motor in it iirc.

Have you driven an old Carburetted car with well set up carbs and a "liberated" exhaust? The throttle response is not instant but its silky, and depending on how the engines are tuned, the right pedal is a thing of joy. My particular favourites are the Fiat/ Alfa/ Lancia 2 litre twin cams and the 70's Datsun 1600 / 180B motors.
Can an EV produce a symphony like these humble 4 cylinder motors? I look forward to trying them but I suspect I'll be enjoying the fantastic response rather than the lead in and delivery of an entertaining (if not massively powerful) ICE powerplant.
The last two 'modern' bikes I've had were a VFR750 and a CBR600..both of which were superseded by EFI models in their next iterations. I.e. they're pretty much the final iteration of carbed engines on road vehicles. I've also got the classic Triumphs of course.
There's no denying carbed and piston engines have 'character'. But IME electric vehciles are in a different league for smoothness and silkyness. They obviously have none of the 'charm' of a conventional engine, but in terms of control and feel you pretty much can't fault them.
Its not just the speed of the response IMO, its the relentless nature of it and total lack of up shifts, turbo lag etc. You don't even need to pull off, the vehicle just starts magically moving IYSWIM. Its hard to describe, you really have to try it. When you throw in the fact the throttle really does work in both directions in an EV you quickly get into intuitively driving on one pedal.

145bhp, 180ft.lb of torque, lovely looking trellis frame...
See anything missing though?
Well now,that's not bad looking at all. I'm slightly encouraged.
Are the boffins gonna fix that milk float soundtrack next?
Please?
Our motors have noise artificially massaged both in and out. Obviously can't say much, but they go into cars from an OEM renowned for their musical exhausts and we help tune the noise.

Ha!
Instead of the promenade Percy's poking holes in their pipes,in the future they can download a V12 sound for their battery Corsa.
I'm unsure if that thought makes me happier or more sad....
