All bicycles sold at REI include a free warranty tune-up. New bikes go through a normal break-in period, after which readjustment is important for longevity and performance. Bring your new bike in to your local REI for its free tune-up within 20 hours of use or 6 months from purchase, whichever comes first. Contact your nearest REI bike shop to schedule this important service.


When you purchase your Diamondback bike on, have it shipped to any REI store where it will be ready for pick up fully assembled (and you'll avoid the home-delivery oversize shipping charge)!

Rated 4 out of 5 by from Great first hybrid for me! After years of trying to make my own hybrid bike from mtn bikes, I finally decided to just buy one purpose built. I'm very comfortable on the upright flat bars, the brakes and shifter work great and the bike glides smoothly and quickly. I love it! No issues riding around a city or on hard packed dirt roads, jumping on curbs, just need to get used to no front shocks. Soon I will mount a rear luggage rack so I appreciate the mounting points. Definitely recommend this bike, $50 back too for members!

Rated 5 out of 5 by from Great deal! I found this bike online and went into the store to try it out. Taking a ride around the block resulted in my buying three of them! My kids and I all got one. Very happy with the purchase. Comfortable, light weight, good price, highly recommended.

Rated 4 out of 5 by from Nice bike but... I like the bike, definitely a nice bike for the price. Have used it once and when changing gears it is now making noise, like the plate is rubbing against the chain so I will have to bring it back to get looked at

For the Diamondback Insight, are the pedal spindles 1/2 inch or 9/16 inch? Neither the Owner's Manual nor the Assembly Guide that came with the bike mentions this detail.

Asked by: gene52
​The pedal spindles are 9/16" on the Insight 2 Disc Bike.

Is this bike good for a bit of off-road/non-path riding? If not, Im looking for something about $500 or less that is light and is capable of offroads.

Asked by: bengrainger
The Insight 2 Disc Bike is a great choice for what you are looking for. It will be able to handle off road riding and could be improved with a mountain bike tire if you are planning on doing some tougher trails.
