Best Mountain Bikes of 2025

"I found the bike very easy to assemble, and it rides quite well for the price. The tools included were a nice bonus."

"I purchased this bike for my husband, and while he was excited to ride, the tire blew out after just 40 minutes. Thankfully, the seller refunded enough to cover a new tire and tube, which was appreciated."

"Though I was disappointed with the bike's quality, the frame felt sturdy. Unfortunately, both wheels were off-axis, and I had to spend $50 to true them at a shop. It's still not great to ride, but I guess you get what you pay for."

"I was impressed with this bike for $200. It looks nice and is reasonably lightweight. Although I’m still getting used to the shifting, it rides quickly and effortlessly. Assembly was straightforward, but I recommend using your own tools for best results. Just a heads up, the seat is quite hard, which can be uncomfortable."

"For my son’s Christmas gift, I bought this bike. It took some time to put together, but it came together pretty easily. However, I faced issues with the wheels not being straight, causing them to rub against the brake pads. Also, the derailleurs were not indexed properly, making shifting a challenge. After spending four hours on adjustments, I decided to return it to avoid further hassle."

"I purchased two of these bicycles and found the assembly to be a breeze. While it may seem daunting at first with the parts, the instructions were straightforward. Once put together, these bikes are truly top-notch. I highly recommend them, but if you're unsure about assembly, seek help or consider having them put together at a bike shop."

"I turned mine into an e-bike, and it's been good so far. I did upgrade the brakes, and the forks are holding up alright. I've put 200 miles on it."

"I bought this bike for my son for his birthday after reading positive reviews. However, I'm disappointed with the quality. The handlebar is uncomfortable, and the gear shift is poorly designed, causing accidental shifts. The kickstand bent quickly, and overall, I expected better for the price. We reached out to the manufacturer but haven't heard back. I would suggest looking for a different bike."

"I was excited to receive the bike, but I can't even assemble it because it didn't come with the necessary tools. For almost four hundred dollars, I expected tools to be included! The bike looks cute, but it definitely could be improved. I'm honestly thinking about returning it."

"I've been riding my Mongoose Malus Fat Tire Mountain Bike since September 2021, and it has been an absolute game-changer for my outdoor adventures! The robust frame and high-quality components have withstood all kinds of terrain. The fat tires are a standout feature, providing excellent traction and a surprisingly smooth ride. Plus, the ergonomic design makes long rides enjoyable. Overall, it has exceeded my expectations in every way!"

"I received my bike a day early, and it arrived in great shape. It was easy to assemble, and I appreciate the good quality for the price. I took it to the beach on the first day, and it performed well. I plan to buy a second one for my daughter since she enjoyed riding it too!"

"I've only ridden this bike for about 60 miles, and it’s been a fun ride so far. It looks nice, and I've made some upgrades to enhance its capabilities. Initially, I had to grease and adjust everything, but now it’s running well. I'm excited to take it out for more adventures!"

"I have been using this bike for over a month, and I find it very reliable. I use it for road biking, and although I moved from a 24 speed 29” bike, this one is still challenging enough for me. The assembly was straightforward. However, I did experience some rubbing with the disk rotors initially, which required a simple adjustment. Overall, I recommend this bike, especially for bike enthusiasts."

"I purchased a used bike for just $160 during the pandemic when prices were skyrocketing. Putting it together wasn't a hassle, but I did face some issues like a damaged headset bearing, which was easy to fix for under $30. After adjustments, I found it heavy yet manageable, with a smooth rear shift. The seat is quite uncomfortable, but after some upgrades, I enjoy riding it. Overall, I spent about $250, and I'm satisfied with my purchase."

"I was initially hesitant about buying a bike online, but this one exceeded my expectations. The quality is great, and assembly was a breeze, taking only about 45 minutes. However, the delivery was a bit delayed due to the courier service. Despite that, I would still give this bike a 5-star review."

"I was pleasantly surprised by how much was already assembled when my bike arrived. Although the shipping took longer than expected, I managed to put it together in about an hour. Once on the trail, it proved perfectly responsive and handled everything I threw at it with ease."

"After replacing my old bike, I found that this one was a solid upgrade. While the suspension is basic, I’ve ridden around 50 miles on various terrains without major issues. I did encounter a clunking noise, but after some back-and-forth with support, they sent me new parts that resolved the problem."

"Upon receiving my bike, I was excited, but unfortunately, the gears didn't function properly right out of the box. I attempted to adjust them and even contacted customer service, which was fantastic. I decided to return it and hope for a defect-free replacement."

"I love how the bike looks with its black and orange colors. The 29-inch wheels are huge yet surprisingly light. After some initial trouble with the disc brakes, I managed to adjust them for great braking power. Although the seat is uncomfortable, I found a replacement on Amazon. Overall, this bike is fast downhill and performs well in various conditions. I broke the chain after a few rides, but customer service was fantastic and sent a replacement under warranty!"

"At first, I noticed some gear jumping, but after a quick adjustment to the cable, everything was smooth. I found the bike very enjoyable, especially the 29-inch wheels. I used to ride Schwinn bikes when I was younger, and now at 61, I'm back into biking for fitness. This bike has been a great choice, and I highly recommend it!"

"I found this bike to be a winner for my height, as I have long legs. After assembly, I took it to a bike shop for a tune-up, which really helped to avoid future issues. It's been great for both trail riding and city commutes. I even added a rack and baskets for extra storage. Overall, it’s a solid bike that meets my needs."

"I really enjoy this bike I got for my son."

"The bike was simple to put together, taking about 30 minutes. However, I found the seat to be designed for a 100 lb teenager, so I had to visit a local bike shop to get a better one. Now it fits me perfectly!"

"I thought this was a decent bag for the price, but it's quite heavy, which slows me down. Unfortunately, I lost a couple of the little pieces on the end of the cables while riding. During an 18-mile ride, the pedal on the right side came off. It seemed like the threads were cross-threaded at the factory because I couldn't get it back in place. I finally had to find someone with a welder to help, but it still didn't hold well. It looks like I’m going to have to take it to a bike shop for repairs, which will cost around $100. Overall, not worth it."

"I had my doubts about the quality of the product due to its price, but I was pleasantly surprised. The bike has a nice appearance and is well-built. The assembly was easier than I expected. My son is absolutely delighted with his new bike. It's a great value for the price, and it even exceeded our expectations."

"This bike is a fantastic option if you're looking for a cost-effective mountain bike for a child. It's well-built and can handle mountain trails well. I found the assembly to be a breeze, although the brakes needed some minor calibration for optimal performance. Overall, it's a great bike for the price."

"I bought both the 24" and 26" bikes, but I noticed some variations in included accessories. One had plastic fenders, while the other came with a water bottle. Aligning the disk brakes was a bit challenging and the instructions weren't very intuitive, which made assembly more complicated. However, they came with all the necessary tools, making it manageable. I recommend starting assembly well in advance to reduce stress. Once assembled, they're nice products with a cable lock mount for added security. Overall, these bikes are worth the investment, especially if assembled by someone experienced."

"For the price, I got a great bike. It's well made overall, but I might need to replace the derailleurs and shifters. Just a tip: don't leave it out in the rain or it might rust!"

"I think it's a nice bike overall. The gear isn't the best, and I’d rate the disc brakes a 6.5 out of 10. I swapped the seat, so I can't comment on the original comfort, but it looked like it could be a pain."

"I've been really satisfied so far! Two bikes with disk brakes and front shocks for under $500 is an amazing deal. They were super easy to build, though I’d suggest having two people to align the front wheels correctly."
