Stay Safe

In Oregon, a bicycle is legally considered a vehicle, and the same Oregon road laws apply. Please “be seen” and practice safe riding. Vehicle traffic, farm equipment and narrow shoulders exist on many Oregon roads, and you may find that construction projects, traffic or other events may cause road conditions or signage to differ from the map results, ride descriptions and directions. For travel options plus weather and road conditions, visit, call 511 (in Oregon only), 800.977.6368 or 503.588.2941. Routes listed on this website are for informational purposes and intended as a reference guide only.

Donut Byte Labs is a shiny blue food cart serving gourmet mini donuts to the greater Portland area! It's located in downtown Portland at 4th & Burnside, across from the Chinatown Gate. These mini donuts are made with science by the Donut Robot™ and hand-decorated by trained Donut Technicians. Donut Byte Labs uses scratch-made flavors, with fresh donuts cooked every couple of hours and cooled for decorations, tasty toppings and house-made pastry creams. Check Donut Byte's social media accounts for biweekly test flavors.

Open Mon-Thurs 6 a.m. – 6 p.m., Friday 6 a.m. – midnight, Saturday 10 a.m. – midnight, Sunday 11 a.m. – 8 p.m.
