Yeah, definitely- as long as you’re up for a bit of challenge. The downhill trails all go fine on a normal bike (I’ve ridden a good chunk of them on a rigid carrera and a fatbike), and you can access most of the enduro trails too. Though that does require you to move pretty quick for some of them, if you don’t want to miss the bus- they take longer to get down. You can keep the longer diversions for the last and last-before-lunch runs.
It’ll reward some research beforehand though to decide what you want to do and find where things are.
You can’t really access much of the red route usefully, which is a bit of a shame- the 2 don’t link up very well. Just the last descent really (you could probably do razor rock too but that’d be a fairly poor use of the lift)
