United StatesQuickly won me over
I nearly returned this bike and I’m very glad I didn’t. My initial test rides through my neighborhood and on flat XC trails, I thought I might have made a mistake as this bike does not carry momentum very well. THAT SAID: Do yourself a favor and put this thing on an any single-track trail. Pull the tubes, pick up your pedaling cadence a bit and it does well. Go do some tech climbing and then go ahead and point this thing downhill through some rocks and logs…. This bike completely came to life. Brakes are insane, suspension is easy to get dialed; poppy bike and plush ride feel. Bike definitely needs to come with a better dropper lever and chain, but the price is right. I’m also glad my bike showed up with 2.4” Dissectors rather than 2.6s. This bike is certainly more toward the “All-Mountain” side of the trail bike spectrum, which is pretty obvious with the 36. If you’re going to do nothing but ride XC trails and a park once a year, get the T8 or maybe a faster pedaling bike. But if you don’t mind holding a slower pace, this bike will wow you on trail. As far as BikesOnline: I give 5 stars as well. The bike arrived with a few minor issues (caliper rubbing, derailleur needed to be properly setup) but BikesOnline made it right. Shipping was fast and the price was fantastic.
United StatesIt’s lighter than it looks
This bike is definitely worth every penny.
United StatesSiskiu T9 March 2025
Very good first impression upon delivery. Bike was packaged very well and assembly was fairly easy. The parts and components on this bike are the highlight. This bike is extremely capable right out of the box and feels safe as well as high quality. First 20 miles have been a joy and the comfort/ capability is very good. Looking forward to growing with this bike for years.
United StatesExcellent bike
Bought 2, one for my son and one for me. Great platform that is well equipped. Looking forward to getting a lot of miles in this summer of this bike.
