I have the 6.8 Nine 2020. Done around 600miles on it since the start of March and the only issue has been the rear hub that needed nipping up. It will be something I look to upgrade in the future as I’ve had Novatec hubs in the past and don’t particularly rate them.
A lot of reviewers talk about the Fox 34 not being heavy duty enough but I’d say that depends on what sort of riding you do and how good you are.
I don’t think anyone needs the Kiox but some would like it more than others. Personally I think either go clean cockpit with no display or if you’re having one make it useful and offer something a bit different. The Kiox does that but it is a bit clumsy to integrate neatly.
I rate the new Bosch but wish I’d have thought about whether I really needed the 625wh battery. For most rides I come nowhere near to using it all and it does come at a weight penalty.
Theres lots to really like about the bike but these are things worth considering. Overall it’s a brilliant bike.
