I’ve got a Bolt Long. Like it a lot. I’ve just been to Fort William and done the Red and World Cup courses on it. Great bike for that sort of thing – truly indestructible. I’ve basically built it up as a downhill-light bike that suits everything up to where my skills and bravery reach their limit. SLX kit with Rockshox Sektors, Stans Flows and some big Maxxis tyres make for a lot of downhill fun on a reasonably modest budget.
The obvious negative is that it’s a bit heavier than some but then I suspect it’s a lot stronger than some too. It also has to run 1x as there’s no room for a front mech. Neither of these things bothered me when I bought it and they still don’t. As thepodge says, they’re shorter than bikes in fashion right now but for me I tend to be hanging off the back pointing downhill most of the time anyway so I’m not too worried about that (I’m 6′ 4”). Another negative might be that you’d be limited in choice if considering a dropper post as the seatpost is 27.2mm.
In terms of pedaling it’s not too bad at all. I’ve got the standard x-fusion shock on and it’s fine but would probably be improved with a pro pedal or something like that. I’ve taken it around Glentress, Comrie, Laggan etc. with no problems and have done plenty of natural trails but it certainly isn’t one for eating up the miles on fire roads.

Given that you’re replacing a fairly aggressive hardtail it sounds like it’d be perfect unless it’ll then be your only bike. There are better options out there if a do it all is what’s needed.
