I wish I could give two separate grades: one for the quality of the bike (excellent — five stars) and another for the quality of the shipping (terrible — 1 star). The assembly was easy, and the bike rode very smoothly after I got it all put together and rode around for six miles. The only problem was that I had difficulty shifting downward to any gear below the 4th. I then noticed that the bike was damaged in two areas: slight warping of the two plates that surround the big gear between the pedals, and warping of detrailer metal plates and the nearby left dropout area of the frame. When I examined the cardboard box the bike was shipped in I found “bruises” (circular tears around 6″ in diameter) adjacent to where the two areas of damage were. It appears to me that the package had been impacted in a way that caused the two widest areas of the bike inside the box to be hit hard. Perhaps the package had been leaning against a wall in a warehouse and a fork-lift backed into it. Except for the slight problem with shifting to the lowest three gears the bike was still functional so I wasn’t very concerned about these problems until the next day, when I started to ride the bike and shifted from 4th gear to first and continued pedaling. I then heard clashing of metal parts and felt the chain derail. I stopped the bike, got off it and examined the rear derailer. I found it had become so warped that it no longer could function (the uppermost gear of the derailer mechanism had warped inwards towards the spokes to an angle around 35 degrees away from straight up, making it impossible for that gear to move the chain). I had to walk the bike back to my house, which was around 100 meters away. A harsh lesson seems apparent: I should have done something to correct the warps in the derailer parts before riding the bike any more. I’ve been able to correct the bend to the rear left dropout. I removed the rear wheel and placed the bike on its left side, then rested the left chain stay on a stack of three house bricks (such that the left rear dropout extended a couple of inches over the edge of the pile of bricks). I then grabbed the left dropout with a large adjustable wrench and pushed hard downwards. The dropout (which had been bent inwards towards the rear tire around 3mm at the dropout’s end) became straight again. The warps in the two disks around the pedal gear don’t seem to need straightening The warps in the long metal plate of the rear derailer appear to me to be far more difficult to correct. I tried to use the amazon site to ask the bike maker to send me photos of a normal, undamaged rear derailer to help me make the needed corrective bends. The amazon site seems to allow no way for one to send such a request to the bike’s maker. I used the option of asking to make a return to send my simple request (for photos) with the message-entry blank, making it clear in my message that I only wanted some photos, and did NOT want to return anything. While doing this the web site bizarrely logged me off twice (I’m certain I did nothing to warrant this).

First thing. I bought this bike to take to the local bike trail and burn some calories.You need to know that it is a heavy bike and anything with the word fat in it should immediately stop you from complaining. It’s hefty.I love it. If you want to power through the pedal like I do it’s great. If you, like me, could peddle all you want on a normal sized bike and still feel like your not moving than a fat bike might be for you. Bumps are not an issue. Feels like a monster truck as you ride.The problem, your buying a cheaper bike. Mine came with a bent bottom bearing or actually the spindle in the bottom bearing. They knew this during assembly. How do I know that. Well the bottom bearing was left loose to keep it from causing issues. How did I figure this out. A 7 mile bike ride and a mysterious clicking sound took me to a local bike shop where a very kind bike mechanic showed me that it was loose and the bent shaft was causing issues. And the bearings weren’t really greased very well.So … It’s a great bike but you should get it serviced before riding. I know this isn’t ideal but unless you plan to pay $1000 or more you should expect this kind of thing.

I love my bike. I bought it for exercise.

I love this bike and do not regret buying it. When I purchased this bike, I was 350 pounds at the time. I am now 297 pounds and love it even more!

Amazon almost doubled the price in less than a month. Unacceptable. Greed at its finest. It was a good value for an entry level bicycle, but certainly not at almost twice the price.

Just purchased another one. I am converting these to e-bikes. Inexpensive, robust a very good entry level fat bike. And an especially good candidate for my use. Nothing lightweight about it. But you’re adding a heavier motor and battery. I like the steel frame because it is strong and I can cut and weld the bottom bracket. That cures the motor mount problems (weld it to the frame) and chain alignment issues. I gear these especially low, the chain wheels have no offset so I cut the bottom bracket to the required width.Everything else that is of questionable quality gets replaced. And surprisingly that is very little. Brake pads, rear axel, ball bearings at both wheels and inner tubes. And these parts were kept on the bike until the heavier, more powerful conversation wore them out. Everything else is good.I rode it as a bicycle for a bit before the conversion, even put on a 3x mt bike chainring to lower the gearing, to high stock. It was fun. But I’m 9000′ in the Rockies and the conversion was the main intent.For the money you cannot go wrong.
