Mongoose Tyax Comp Adult Bike, 27.5-inch Wheels

I gotta say I'm pretty impressed with this bike out of the box -- shifting and brakes were adjusted perfectly and wheels were fairly true but the hubs were a little tight, but easily adjustable and now very smooth. Wheels and hubs seem like they are built to last and are not very heavy at all, even with the tires.The Shimano shifting and Tektro brakes are great -- better than what came on a $2k 'boutique' bike I bought a few years ago. The rest of the parts are almost as good -- hub engagement is not bad at all for a budget hub, also much better than my previous more expensive bike. Gearing is totally adequate for me at least with even steps between gears which is nice, plenty of low for climbing, but could run out of gears on really fast downhills.Frame seems great -- Lightweight, seems well engineered, everything bolts on smoothly and straight, and the welds are all good and visible which I like better than the toothpaste looking welds on some bikes. Can take an internal dropper too. Fits me perfectly based on the website suggestion, but I still need more rides to tell about the stem for sure.The bike rolls smooth and fast! Can really cover ground with the 29er. This bike climbs great and is really comfortable. I climbed a big hill in my neighborhood just because and I never do that! I LOVE the orange color!The seat and grips are much better than expected, and the pedals are ok too -- very light and spin smooth and should get better with use. I thought I'd swap all those out immediately but have decided to try them all longer. The tires are also pretty good, not too heavy, roll ok on pavement/hardpack, and pretty good in the dirt so far. Another pleasant surprise.The only real gripe I have with this bike is the fork -- it is really heavy and just so-so in performance. I did ride with it for a day but then I swapped it out for a lighter air spring fork. Not a terribly expensive upgrade and the performance increase is incredible -- wheelie game is much improved haha! And yes, this bike wheelies great!My first real BMX bike in the 70s was a Mongoose Motomag -- it's GOOD to be back on a Mongoose!**Upgrading this to 5 stars from 4 because I realized the hardware to upgrade to 12x148 rear wheel is built into the frame! No additional dropout hardware needed! Upgrade at your own pace if desired. Love this bike!**
