I got around to reviewing the Tailwind I've been messing with for the past few months.
The battery lack is a SCiB lithium titanate chemistry and was a source of much pain and annoyance as the BMS quit entirely (or locked itsself out - not sure which).
I finally posted a review of the whole bike, with plenty of pictures as well.
