I would buy this again at sale price if I was just starting out but now I'm looking at a $3000 full sus on clearance. Expect to upgrade if you want to ride it forever. I bought my gf the expresso and honestly do not buy that, buy a Highline 1.
I swapped the tires to 2.35" schwalbe nobby nics. They seem to roll faster and have much better grip. I've put in a stiff spring in the fork.
I've put this bike through its paces but I'm outgrowing its intended usage of being a mostly single-track bike because I've been riding woods for 3 months and here there's a 1500m elevation with a ski hill. It's obviously an entry-level bike and it has its limits but I can confidently say that if it just had a stronger front brake + dropper post + air fork you'd have a very capable light-weight bike for light downhill + rocky trails and I THINK all of that can be upgraded. In OEM form the coil fork suffers due to my 250lbs - I put a stiff spring in which did next to nothing for rebound. The fork works well even for larger city curbs but once you're going downhill and hit rocks it can squat and stay low in its travel - if Suntour offered a dual-spring fork it would probably work for heavier riders (there's one spring in the fork). I've never bottomed out and it measures closer to 130mm.
The deore 10sp shifts SO WELL! It basically doesn't miss shifts ever but if shifting quickly from like 7th to 10th it can skip 10th and derail but it has only happened once. It doesn't require maintenance past cleaning the gunk out of the derailleur cogs and as long as you're not shifting under too much load this thing is snappy and handles quick up/down shifting so much better than older twist designs. The only maintenance I do is use a toothpick to clean the gunk off the cogs and wax the chain. I've never even taken a hose to it. I've never thought "I need more gears," either.
The only real point of failure complaint I have about this bike out of the box is the plastic clips that hold the wires to the frame - they pop off so easily and my shoes hit them, I've lost a few, and secured almost all of them with zip ties instead. I don't know if this is intended but it might as well just come with zip ties to begin with even if it doesn't look OEM. I don't like the presta valve, I use an adapter.
Suggestions: include a water bottle holder, possibly a faster engaging crank as there's a bit of play and in slow rocky sections you want instant power-to-ground. I would have included boost axles instead of 9mm QR, that way people can upgrade without changing out the whole wheel. More expensive, but most would appreciate the universal sizing, at least on the front wheel when fork swapping. Other than that everything else is pretty tight, my grips aren't even worn under 95%. Everything else is super durable.
There's tonnes of positives with this bike: the seat is comfy, everything is upgradable, it's light weight. I suppose I'm describing upgrades as the Highline 2 but I wouldn't buy a Highline 2 because I don't like the fork. I'd rather forgo the M5100 for the M4100 drivetrain and upgrade the fork to a Fox 36. The Highline 2 is too in-the-middle, I wouldn't even offer it, just make the Highline 1 more universal sizing.
The Tektro M275 work flawlessly even with their somewhat on/off feel. Lots of power on flat ground, but when you go 30 seconds downhill they'll heat up and fade a smidge. They'll still work when heated, but it's mentally scary. Out of the box the only component I'd change is the front to a 4-piston & 200mm rotor, for safety because people are going to push their limits on this bike because it's so inviting.
First ride was like a revelation into fairly modern design. I rode this every day for 6 months last year to lose weight and gained a pound of muscle in my quads instead (calorie deficit works better for weight loss). When I first started any uphill winded me terribly, to the point I'd nearly faint, BPM 180 and I'm just breathing for dear life. My legs would burn and it was very difficult to climb. Now on those same 150-foot climbs my heart rate doesn't get above 120bpm and my breathing is barely working hard and I can speak coherently after. Technique changes over time, and I learned that downshifting doesn't always make a climb easier, sometimes it's easier to just keep it in like 8th and stand up and have a slower spinning speed, especially in the hot sun. I've significantly reduced carbs and it seems to have a positive effect on my circulation. I've lost 58lbs since a year ago. Another thing I've learned about is pre-hydration: before any big ride I'll chug a liter of plain water and then slowly sip a liter of an electrolyte mix (200mg magnesium biglycinate, 500mg potassium, 1800mg sodium). This is absolutely necessary for me to not get a migraine 1.5 hours into a ride. I even pre-hydrate my dog now for big walks.
