I bought a replacement bike elsewhere which I love. The Supertech GTS is a great bike!
In November 2020 I saw that Scootech is selling a Supertech in grey which looks like the same bike I returned. I took screenshots of the Facebook Marketplace advert and have posted these below. The bike is LV70 UBJ. The ad does not mention that this bike was bought, driven, suffered a fault and was returned. In fact the advert states that it has had "just 10mil pdi test". In case this is the same bike that I owned then please beware if you are considering buying it.
