Top Mountain Bikes Under $650

Six hundred dollars is an important step in the world of mountain bikes; this is where you can buy a bike that is ready to take out on real mountain bike trails. At this price point, bikes start to be available from some of the big name brands, and the value brands start to offer some of the features that make a modern mountain bike perform.

Features you can expect for under $650

  • Strong and reliable fork that can handle use on trails
  • Disc brakes (the best bikes in this price range will have hydraulic brakes)
  • Aluminum frames
  • Tires with quality rubber compounds and tread patterns
  • Trail capable drivetrains (derailleur, chain, gears, shifters)

Features you won’t find in a $600 mountain bike

  • Lightweight – bikes in this list are likely to weigh 28-32 lbs / 13.5-15 kilos
  • Air fork with fine adjustments
  • 1x drivetrains – this one is starting to show up, but many good bikes at this range still have a front derailleur
  • All mountain trail tires – most bikes in this range have lightweight “XC” tires
  • Dropper post

Mongoose Dolomite ALX

Mongoose Men’s Malus Fat Tire Bikes

The Mongoose Dolomite ALX is a fat bike, which uses cushy big tires instead of complicated and expensive suspension shocks to make for a smooth ride over bumps. The wide tires also allow you to ride on top of sand and snow.

The Dolomite ALX has some pretty basic components, and is very heavy compared to the other bikes listed here. However, you get something completely different, and this is the cheapest fat tire bike with an aluminum frame and quality components that we could find.

Marin Palisades Trail 2

Price: $799 (currently available for $500-$600)

Marin has a long-standing reputation for making fun trail bikes. The Palisades Trail 2 gets great reviews for how it rides, and has a level of components that is hard to beat. The MSRP on this bike is well above the $650 limit for this roundup, but it seems to be available for less from multiple retailers.

The Marin Palisades Trail 2 has modern geometry, and is fairly “slack” for downhill stability. The tires are genuinely trail capable and very well regarded for their grip when pushed. The RockShox fork is still a coil spring, rather than air, which is the same as everything at this level, but it is a step up from the others we find at this level. The hydraulic brakes are another plus that most bikes from big makers don’t offer for this price range.


  • Well designed and made
  • Solid Shimano and Tektro components
  • Hydraulic brakes
  • Excellent WTB Trail Boss tires


  • Heavy and basic components (e.g. 2x drivetrain, coil fork)
