  • Great Bike for the Price.
Color: Fat Tire-Black
Not a bad bike for the price. Easy to assemble, the video helped. Comes with it's one tools. Had to replace the factory peddles with some bigger one due to my feet being so big. Didn't trust the almost all plastic peddles. Had to replace the quick release seat bolt with a regular bolt, no mater what I didn't I couldn't get the factory one tight enough so it wouldn't move. Was able to get a cargo rack install over the big tires with easy. Replace the kickstand with one that had dual legs, had to make a mount for that do to the tires being so big. ... show more

  • Skeptical at first but turns out to be a decent bike
I purchased this bike before reading reviews and instantly thought I had screwed up. People saying instructions were hard to follow or didn't make sense were correct but I have personally never put a bicycle together and I did it with out instructions.. it only takes a little common sense. The only problem I hade was the handle bars set to low for my as a bugger guy but a simple trip to the local bike shop and an adjustable stem later and it's an amazing comfortable ride. ... show more

  • Aluminum wheels not aluminum frame per magnet. None the less a great budget friendly purchase.
Color: Fat Tire-Black
A good purchase for the money except.....The frame is carbon steel not aluminum as advertised. The wheels are aluminum. Shifts good, handles good, a little heavy but okay for a fat bike and the brakes were surprisingly good after taking up the slack in the cable at the caliper. I was going to replace the calipers with hydraulic but after riding I'm not. I have had the bike out in the snow on the trails at the local bike park. Snow trails will all be on the smallest front ring but it's nice to have options. Came with tools and a bottle cage - nice touches. Overall a really good purchase. Gets it done. ... show more

  • No No No!
Im a bike guy so figured I'd just fix any minor problems that would arise with this uber-cheap, all steel, nearly 60 lb fatty. Sometimes it just aint worth it it. Theres a slew of these hump-backed steel frame bikes out there going by various names. First, that cool looking hump - check you standover height or you'll injure a gonad. Next - The right brake adjuster knob was missing & the left trigger broke on first ride & was replace with a $16 EF-51 shimano copy. Then noticed it was impossible to adjust the front disk brake due to both a bent rotor & slightly tweaked lower fork stanchions. Then on the last ride the freewheel stripped on 1st gear. Apart from all that its a great bike! Yeah right ;-\ ... show more

  • Purchase handlebar riser for taller folks
Purchased this bike for my son. 5'11 and almost 300lbs. It came half assembled as described. Watch the video and it helps especially for first timers. The inner tube was faulty. When we went to fill it. It burst at 15psi. I contacted the seller thru email on the card that came with. They were helpful and sent us a replacement no issues. Recommend not filling higher than 25psi even if the manual says 30. The handlebar is fixed and my son almost hits his knees pedaling and needs to lean over and hurts his back. He uses it just pavement riding not off roading. Recommend purchasing a handlebar riser for easy riders. ... show more

  • Almost great.
Nice looking bike. The fat tires are awesome. Definitely makes trail riding even through my very easy. I wouldn't suggest riding on roads because tires make it tough. Assembly was simple. 5ook aboutv20 minutes. 2 complaints though. Rear braking system already isn't working and gears don't switch as smooth as they should. Otherwise great bike. ... show more

  • Great Economy Fatbike with Front Suspension!
I bought this black fatbike to compare with a couple other economy fatbikes I have because the frame looked intriguing and there was a front shock. I wanted to see how well a basic shock worked, and its pretty good! Combined with low 8-10 psi in the tires the shock does good smoothing out bumpy dirt roads and mild rocky trails. It has no damping or adjustment, simple spring action, is thunky both when fully extending and bottoming out so that is somewhat annoying on heavy bumps but really it does great on the mild bumps. The Tourney level derailleurs are ok but did not have the range for the megarange cassette I swapped in for better gearing, so I put on an Alivio. The front derailleur mounts on a standard size tube so you can put on whatever you want. The frame and shock are worth the price, then add wider range cassette and chainwheel if you want a true climbing bike. I put on a Vuelta MTB Comp Crankset. Brakes are nice and decent. The shift levers are wonky so I put on a set of gripshifts but the stock ones work ok. Very fun bike! The top tube is really tall to stand over, 36" from the ground mid tube. ... show more
