You are highly unlikely to ever have a problem, but in a pedantic technical sense there is a lot wrong here. 1. Your motor is not marked by the manufacturer as 250W, and so technically is not compliant. 2. Your DIY labels are purporting to be by the manufacturer and so are misleading. Lawyers...

The online specification says 'mechanical disc brakes', and the noise started when you changed the pads. Most of this type of brake have one pad fixed and one pad moved by the cable and mechanism. Did you adjust the fixed pad position when you replaced the pads? If not, it may be contacting the...

Even that rather professional looking attempt has the same spelling mistake!

Your biggest problem is your determination to break the assistance speed limit. The current focus of enforcement is exactly that. It doesn't matter how big your battery and controller box are provided they are fit for purpose and safely mounted, but if you are stopped with an illegal top speed...

Having the correct EN number is more important probably than the spelling error, but both errors say 'fake label'. If the motor model number is engraved, that plus a copy of the manufacturer's specification might be as good as anything.

If your bike matches the spec I see online of 27.5 wheels and 48T chainring, then the chainring is too big for hilly terrain. My 700c bike has only 38T, which is equivalent to about 41T with 27.5 wheels. So a first step might be a 40 or 42T chainring. They will give the effect of the cassette...

Smaller required if cassette stays the same.

Yes, just fit a cassette with a lower bottom gear, and expect to replace shifter, derailleur and chain as well. Shop around, not as expensive as you might think. Straightforward to DIY, or to make use of a friend's skills if you don't fancy it. Bear in mind that in those lower gears you will be...

If you Google the bike name, it seems to be a TCM motor, and it seems that @Woosh used to use them. I wonder if they can help? If not, something that old that is no longer in common use is probably not worth much effort.

You need a buyer not afraid of the lack of warranty. Looked after, it will likely do well for many years, but mid-drive without warranty is a big price hit. Discounters have this brand new today for £2250 and upwards, with full warranty. I would be surprised if a buyer would pay more than half...

The difference between a 16 and 20 inch hub motor is the nominal rpm. Most kits give a choice. I only know 700c number off the top of my head, which is 201rpm. You need about 7/5 x that, or about 280rpm. Have a look at what's out there.

Search the forum for Brompton threads. Probably all you need to know is already there.

Only useful for Shimano equipped bikes, and even £90 might sound expensive for a bargain, but usually £140 or so. 4.6A compared to 1.8A for the usually supplied charger, very useful upgrade if you want to recharge during lunch breaks on long rides. https://www.ebay.co.uk/itm/135662425496

Change your bike. No way to bypass the torque sensor.
