A steel utility vehicle designed for fully-loaded exploration, whether across town or across the country.

A Versatile All-Season Commuter Bike

If you're like us, your bike needs likely change by the day, week, month or year. Quite the adaptable little beast, Ogre can get you to your job during the week, then way out of town on the weekend. It's not sluggish on pavement or gravel and can also hold its own on singletrack.

Ogre is designed to be the ultimate steel utility vehicle. It relishes in those "take-the-long-way-home-and-find-some-beverages-along-the-way" sort of commutes. Snow, sleet or sweltering humidity, this is an ideal year-round commuter bike. You can also haul enough crap on it that you don't even have to go home if you don't want to.

• All the barnacles you could ever possibly ask for including rack and fender, multiple three-pack mounts and mid-blade.
• Gnot-Boost rear spacing with Rohloff torque arm slot and Bill/Ted trailer mount
• Clearance for 29" x 2.5" or 27.5" x 2.8" tires with fenders

• 4/5 with Off Road Off Road: 4 out of 5
• 5/5 with Bikepacking Bikepacking: 5 out of 5
• 4/5 with Pavement Touring Pavement Touring: 4 out of 5
• 4/5 with Tire Clearance Tire Clearance: 4 out of 5
• 4/5 with Commuting Commuting: 4 out of 5

NOTE: You can ride your bike wherever the hell you want, but this is what we think this bike is best at.
