Slightly confused (normal) on the woosh site the are selling the TSDZ2 as 48V 250W does anybody know if this is the 36V version with a 48V battery or the 48V version somehow derated to 250W?

The hoses mouth, perfect. In that case I would like to use a rack battery, the only one I can find (that doesnt look like a brick) is 48V 10.6Ah, continuous discharge 15A and max 25A obviously I wont get the range but would it be suitable for the motor?

that's a bit low. The TSDZ2 can pull 16A-17A if you push hard (most people who need e-bikes don't have the strength so it won't go that high). The rule of thumb is don't pull more than 1.5C to avoid stressing the battery.
C=10.6A in your case.

Some of us have the experience of 10.4 Ah batteries suffering after being used with a mid-motor. I don't think they (mid-motors) draw more current than a hub motor but they seem to ramp up the power much more quickly and the cells in your 10.6 Ah battery won't like that very much... I get around that problem by using LiPo which can handle the current draw and if I need more range, in parallel with the tired Li-Ion battery - that makes it a 20 Ah battery.
