Not sure how. You can cycle faster than 15.5 mph, you'll just not get any assistance from the bike.

I notice a slight drag as the assistance on my ebike cuts out, but above 16-17mph it's no different from a "normal" bike. I can maintain an easy(ish) 21-22mph on mine I until my ageing body cries enough.
Can I assume that if eg you are free wheeling (or pedaling) down a hill it will act as a normal none e bike ?

You've asked this question a few times, and the answer is still 'yes'.

To delve into it a little deeper, the greater mass of the ebike means it tends to gather a little more speed than a push bike when freewheeling down hill.

Braking is more of a challenge, but nothing decent hydraulic discs can't handle.

My old ebike had normal bike rim brakes - nothing special
My wife's folder also has basic rim brakes
I have not had a problem stopping either of them compared to how I expect a normal bike to stop in spite of them being heavier
Of course, I am quite heavy myself so most of the excess weight on the bike is caused by my diet

OK - I need to say that I massively prefer the hydraulic disks on my own ebike - but that is more to do with feel and confidence - and, of course, the important point that they still work when the wheels get wet

..just after I got my ebike I tried it out on a local long "downhill" bit and got over 40mph...but very scary and I will not be doing it again, (not sure that a polystyrene helmet would work very well if crashing at that speed!).

I put a ceiling on my speed of 25 mph. As I have got older I seem more and more aware of what 'could' happen.

I agree with your remarks about the ride of the Bosch system.

Most of the time I like its unobtrusive nature, although there are times when I wish it had more obvious in your face grunt.

Backup is a mixed picture because not all Bosch dealers have the relatively cheap diagnostic kit.

The term 'Bosch dealer' is something of a misnomer, 'reseller' would be more accurate
I was chatting to our Bosch dealer today about diagnostic’s & he said after doing the training coarse they get a black dongle to diagnose motor’s but to be able to change perimeters etc the main uk Bosch manager has a silver dongle & only he can change these.😬😬🤔

Yeah - but at 40 m[h a crash is likely to involves a lot of skidding over tarmac but you head will mostly hit the ground at an acute angle and probably be OK (probably - do you really ant to go with probably won't be a vegetable!)
So a helmet is not as much use as you would think unless your head hits a stationary object - like a wall or car etc etc.

I still wear a helmet - but the only crash where it has helped was at about 2 mph going round a corner

Sounds like increasing levels in wizardry
all bow down before the holder of the Octarine dongle

(maybe I read too many fantasy books)
