A rugged and dependable gravel bike ready to kick up some dust as you redefine what’s rideable. The Boundary has the geometry of a road bike with the heart and handling of a trail bike so you can rumble confidently across all kinds of mixed terrain. 

According to the Federal Highway Administration, there are 1.4 million miles of unpaved roads in the U.S. just waiting to be explored—and we haven’t even looked up the international mileage. So take the roads less traveled, or the ones that don’t even show up on the map. Are you ready to push your boundaries?

This Bike Is For You If...

You're looking for an epic carbon-fiber gravel bike that won't break the bank. You'll be able to run 700c or 650b tires with plenty of clearance, install up to three water bottle mounts and racks in the front and rear.

You're ready to take your riding to the next level and race in any gravel event. In 2019, the Boundary made its fast debut by placing 3rd at the Unbound Gravel 100. 

*Max packed out weight — 300 lbs.

Shipping & FAQ

Shipping & Delivery Options

Obed bikes ship pre-assembled factory direct to your doorstep with a super simple setup process or delivered fully built by a technician. Learn more about our Domestic and International Shipping & Delivery Options.

Have more Shipping Questions? Check out our frequently asked shipping questions.

What should I do if I am between on two sizes?

If you can achieve your required seat height with both bikes sizes, then you can pick based on your riding preference or style. The smaller frame will be more nimble while the larger bike may feel higher and faster. LiveChat with us or email us for help finding the right size.

How do I mount accessories onto my Obed?

Our Baseline and Boundary models have various mounting points for a multitude of accessories available on the market. 

For nutrition and hydration, our water bottle and top tube storage mounts can be used with most 2-hole accessories designed for M5 x 0.8mm mounts spaced 65mm apart. The screws provided with the frame are 10mm long and should be replaced with longer screws should your accessory mounting bracket be more than 3mm thick.

At the rear of the bike, we have provided fender and light rack mounting points.  Unlike many metal bikes which may have open ended mounting points, our carbon fiber frames have closed end mounting points.  This requires special attention to the length of screw when mounting racks and fenders with various thickness attachments.  Should the accessory mounting point be more than 2mm thick, source screws that are 10-13mm longer than the thickness of the item you’re attaching. 

For fork mounted accessories, the same rules apply as mounting to our seatstays and dropouts.

We recommend a 20lb load weight limit. 

What is your Return Policy?
