Okay, thanks. It's starting to get a bit complex but if you think this is the best way & best bike option then so be it. Really appreciate your help.
Is there a particular store or online shop that you would recommend i get it from? I have a cycle to work scheme option with work so hoping I can get it through that. Thanks.
If you want a legal bike, it's the best option. You can only buy that bike from Leon Cycles because they are the agents for Das Kit bikes in the UK.

The reason this bike is suitable is that it has a 48v system, which gives 33% more power compared with the equivalent 36v system. Most ebikes run at 36v. Some other 48v bikes would be suitable. There are some on Ebay, but mainly with small fat wheels. Don't be tempted to get one with the big 750w/1000w/1500w direct drive motors. They nearly always have under-rated batteries, they're very heavy and not particularly nice to ride.
The Speed limit situation is not at all complicated. The limit is in the LCD software. There are three versions of the LCD:
1. Fixed 15 mph max speed special to NCM UK bikes, like the Moscow.
2. Adjustable speed limit with same connector as NCM Moscow, found on other Das Kit bikes and avaialable as a spare part. Leon Cycles will sell it for £150 as a spare part.
3. Adjustable speed limit with reversed connector, found on many bikes, as it's a standard catalogue part. It can be bought from Aliexpress and sometimes Ebay.
There's another reason to get an alternative LCD. Normally, the LCD has three power settings as well as 6 speed/power levels. The power setting is a current limit, say, 5 amps, 10A and 15A (Eco, Normal and Power IIRC). The Moscow one is locked - I think on the max.
You can read a lot about it here:

The NCM Moscow is not a bad bike as it comes. It's just that you have the opportunity to make it a lot better. If I had one, I'd strip out the controller and LCD and fit a KT controller, which gives you complete control over power and speed and it's a lot simpler and nicer to use, and you can fit a throttle. Total cost about £80.
