The problem is i cant find a suntour HESC bottom bracket 73 x 136 secondhand....a new one ive found is around £40...also there is a metal ring that fits onto the side of the bottom bracket which prevents the crank torque sensor cable from being ripped out...which i cannot find on the internet....as stated i know the suntour system is crap...but hopefully i can keep the bike working over time,also im not using the bike every day but only times when i want to travel longer distance...ive learnt how to repair the electronics in the motor so i should be able to keeps things going on that front....i think the main problems will be the controller and maybe LCD and the BMS in the battery case...in the future....

Your decision is not based on logic. You're going to have a problem with the battery in the near future, especially if you don't use it much. The Suntour torque sensor you want to use will also pack up pretty soon. Any sensible person would change that stuff now or start afresh with a different bike. You're going in deeper and deeper with nothing to show for it.
An old Oxygen, Wisper or Freego with the battery behind the seat tube can be had with a knackered battery for about £200. You can get a 48v battery for around £250, a KT controller kit for about £80 and a pair of good used hydraulic brakes or new Chinese ones for about £40, then you have a really nice, comfortable and powerful bike with a legal throttle if you want one, and as much range as you want. That would be a much better project, and no problem getting parts for it.
The bikes you mentioned are all small wheel bikes....i like at lest 27.5" wheels...my Trek mountain bike has 29" wheels but with an 17.5" frame...which is ok for me even though im a short person.......i have been able to buy two secondhand batteries which i bought very cheap...which will help keep the bike going. I use to do electronic repair work in the past but now retired,so i can tackle some of the things which may go wrong with the bike in the future....most things can be repaired as long that its only discrete components...if processors then it becomes junk !!! I was not sure that it was legal to use a throttle on an ebike...i think a throttle is far better than pe dal assist !!!!
