The 42 x 60Ah thundesky pack in my vectrix was originally installed in 2010
It's done 105'000km, and around 1100 cycles equivalent
capacity is down to 45Ah

The e-rider's lack of BMS is likely what killed the first 4 cells

For your application, the e-rider continuous discharge rate may be a little high for good service life (stay below 1C continuous for best results)
Your best bet would be either the CALB CAM 72Ah cells, or using leaf modules

YMMV

I have a ~10 year old ThunderSky LFP pack that has given me more than 50k miles; about 5 of the 48 cells have been replaced. The pack is still at around 80%. In contrast, my Leaf gave me ~25k miles and was below 70% in only two years. ThunderSky did not have a useful warranty. Nissan refused to honor their warranty. I'd rather deal with ThunderSky than Nissan.
