They focus on value where it counts, like on components and strong wheels.

Also there is a high standard when it comes to Diamondback brake systems, which is not all that common on budget mountain bikes.

When choosing inexpensive bikes, Diamondback offers good quality.

It is almost impossible to find a pro-level mountain bike under $600, but the Diamondback Overdrive Sport($700) comes pretty darn close.
