OK - this is how far I've got with it
It's a bit Heath Robinson in places, but it all works - please let me know any glaring mistakes !
Started off with the donor Carrera Vulcan £75, the SWX02 kit without battery was £252 - I'm just using the battery for my mountain bike that came with the BBS02B kit ( keeping the BBS02B for off road) - which is one of these (with the slightly unusual 5 pin output).
Put some more road orientated puncture resistant tyres instead of the knobbly ones.
Seems great - plenty of oomph up the hills (it is winding code 12, which I saw described as the high torque rather than the high speed)
Conversion was very straightforward (needed some help from my bike friend to swap the disk rotor and cassete) - lhs PAS sensor - think these slightly older / more basic bikes are good candidates for donor bikes
Having ridden it, the only thing I notice is the PAS levels (and surprisingly throttle levels) seem to be voltage controlled rather than current based.
I have set it to 9 levels of PAS, and I can usually find a level I am comfortable with in terms of peddling / assist but I may change it at some point (I guess that would need changing the display and controlller)
Anyway seems an option for a budget long range 48V electric bike
More planned - got some hydraulic brakes to fit, kickstand, suspension seatpost and comfy saddle, lights, swept back riser handlebars
