If you take the plunge with the Levo, key thing is to get it from a dealer who knows the bikes, and secondly, which you have already done, is to do your research, end up on this forum, and be aware of the potential issues.
If you are aware of what can go wrong, and the steps you should take to avoid these issues (or make sure your bike shop has done them for you) then you should be ok.
The reality of the Levo, is that in the quest to integrate everything so much means that its a far more complex bike than a lot of other EMTB's, and as a result has more fiddly nooks and crannies. As such some of the maintenance reflect this.
