Aluminum Fat Bikes with Powerful Disc Brakes Gravity Monster Mens Fat Tire Bicycle 26" x 4"

I purchased two bikes 2 weeks ago. 1 for my wife, which was green and had the 14" frame since she is only 5'2" tall. I got the black one in the 18" frame and I am 5'11" tall. We ordered them direct from the company website which is Bikes Direct because they don't charge the $50 shipping charge per bike from the direct website. So, in short, these bikes are awesome!The fat bike market seems to be either cheap steel frame Mongoose's at $200-$350 or $800 Diamond Backs and on up into the thousands for really nice ones. The middle ground market is pretty bare. I wanted an aluminum frame and at minimum 4130 Chromoly steel forks. That would help get the weight of the bike down. The reason I did not choose the Mongoose Juneau is because of the quality of the components! The components on the Gravity Monster are very decent quality right out of the box. Yes you can upgrade and make the bike lighter but you really don't need to till a component fails, then you can upgrade easily, but trust me, this bike rides great right out of the box.So here is the secret of this bike:apparently the owner of bikes direct gets the frames and forks made by the same Chinese company that makes companies like, GT, Redline, and a bunch of other big names. I think he may use some sort of generic template where he specifies the geometry he is looking for and they provide him frames based on designs they already have. I may be wrong, buy what counts is that if you google some fat bike forums you will see that some pretty expensive bikes are made using these frames. Then what the company has done to keep costs down further is to standardize the components with brand names like Shimano and SRAM, but every bike gets the same components. Whether it is the orange, green or black, 18" or 14", they all use the same stuff.In the end you get a really decent, pretty light aluminum frame bike that would sell for $700-$800 in a shop for a lot less. You cannot go wrong with this bike! I set both bikes up and then took them to a local shop to make sure the derailleurs were right as I am a bmx guy and don't know shit about derailleurs! My technician said these were really solid bikes with pretty good parts and he would not upgrade anything til it broke as you could probably only save about 5lbs total anyway. He did point out the difference in some components, for instance the SRAM that comes on this bike is plastic, whereas he showed me a Specialized race bike he was repairing that had the same Sram component in lightweight alloy metal....that will be an upgrade later.Anyway, buy these bikes, you wont regret it.

Amazing bike. I am 6'5" and have never had a frame this big (22") or tires this big. I am very impressed with this bike. I bought it to try out a fat bike and convert it to electric. It is now my favorite bike ever and I don't want to ruin it by converting it to electric. I am 45 yrs old and haven't enjoyed bike riding this much in 20 years. I plan to add a third front chainring to get even more speed. It should be an easy and cheap conversion. Thank You Gravity people.

This bike is wonderful, especially for the price. Rides well and handles poor trail conditions without a hitch. Gets lots of attention when I ride it. Some of the parts are quite low quality though - particularly the pedals, handlebars, stem, seatpost and seat. All easily upgradeable. I am very satisfied with this bike and recommend it.

Great BikeI bought 4 bikes and a trike this summer. This bike is a hit with everyone in the family.This Bike handles heavy riders with no problems. One son crashed it after riding thru a puddle . The ingeries were his pride a sore knee and a pedel. Replaced the pedels and time fixed the rest. The son that crashed is 6'3" and 350 lbs.Large riders put alot of pressure on the handle bars and front wheel. I bought a extension to raise the handle bars 3 inches and that helps alot. The brake cable limits the amount the bars can go up. Future plans include hydraulic brakes. Adjusting this bike with prime delivery is quick and effective.For a big person this bike is great. Only regret is not buying one last year.

This is the second Gravity Bullseye Monster I have purchased for riding on the beach. So far, they are getting the job done. I didn't want to spend thousands on bicycles that would be exposed to sand and salt water. At the same time, very low-budget bikes are too heavy and rust-prone. This seemed like a cost-effective approach for a bike that's going to get a fair amount of abuse. I should also add that the "orange" is really a beautiful metallic red with just a slight hint of orange. The photos don't do it justice.

At this price a real value. Assuming it holds together for years. That said, it is shipped by FedEx which went to great lengths to destroy the box. It was taped up and patched together. The bike had several bad scratches and I had to adjust the rear derailleur which I think left the china factory properly adjusted. And the shipper requires a signature when the package is delivered. Which is a pain in the ass for people who work all day. And FedEx does not make that any easier, I ended up picking up my package at a FedEx location. Gravity should drop FedEx and use UPS!

So far I've only looked at it in the box and pulled it out of the box. I didn't understand the tire sizing, but I got the bike according to my height further sizing chart. The box is bigger than I thought, and the tires are about twice as large as I thought also. I'm 5 foot 10 and it said I should get a bike with 16 inch tires. My kids bikes are 16 inch tires so I didn't understand how a full grown man would be on a bike with 16 inch tires. But looking at it now I imagined 16in is the radius of the tire not the diameter of the tire as most tires are sized. I bought this because I got a great deal on a bafang mid Drive motor for 100 mm fatbike, and currently I am pleased to say it looks like it will fit perfectly.

Amazon reviews, forums, and YouTube videos were spot on. Great bike. May need some upgraded components over time. But so much fun (it’s my first fat tire). Also - fast shipping and a free flask comes in the box? Thanks!
