Diamondback Overdrive 27.5" 1 (2018)

Sold out


Diamondback builds bikes that are a blast to ride, and you’re not having a blast if you’re weighed down by a boat anchor of a bike frame or crummy components. So while the Overdrive 1 is certainly affordable, it still features a fully hand-built and hydroformed aluminum frameset that belongs on a bike with a much steeper price tag.

That finely sculpted frame rolls on nimble and quick-handling 27.5” wheels. And when you’ve gleefully tested the limits of the Overdrive 1’s 80mm SR Suntour XCT suspension fork, you can easily bring this machine back into control with the bike’s mechanical disc brakes. Time to head back up the hill for another lap? Thanks to the Shimano drivetrain, you’ve got 24, accurate shifts that give you plenty of gearing to regain the summit … or take you anywhere you want to go.

Ready Ride bikes are shipped 95 percent assembled. Typical bike assembly is time-consuming and requires technical know-how. Ready Ride reduces the time and skills needed for the final, four-step assembly.


  • Hand-built aluminum alloy frame is lightweight yet sturdy
  • 27.5” wheels offer quick handling
  • SR Suntour XCT 80mm suspension fork increases comfort and control
  • Shimano 3x8 drivetrain provides ample gearing for the steepest climbs
  • Tektro Aries mechanical disc brakes provide great stopping power
