The Urrun 20 combines a 630Wh internal battery with an aluminium hardtail frame and a 120mm Marzocchi Bomber Z2 fork. It's a useful option for riders who want Shimano assistance for hills and longer routes.
An OC MC22 dropper lets you lower the saddle for descending. Shimano Cues 11-speed gearing spans an 11-50T cassette, alongside MT420 hydraulic brakes and 29in wheels with Smart Sam tyres. The dropper and Bomber fork are important differences from the Urrun 30.
The EP600 motor uses Orbea's RS Gen 2 MC tuning, which focuses on a natural response to your pedalling. Smooth-polished main-frame welds give the alloy chassis a clean finish, and the included removable mounting kit makes room for compatible accessories when the route also has a practical job to do.

Assistance that follows your pedalling
Orbea's RS Gen 2 MC tuning is designed to make the Shimano EP600 assistance respond naturally to your pedalling.
630Wh inside the frame
The Urrun 20 comes with an internal 630Wh battery, housed in the down tube. This is the supplied battery capacity for this build; no range extender is included.
A smooth finish in aluminium
Orbea polishes the main-frame welds to give the Urrun a smooth, continuous-looking finish. The result is a tidy finish around the frame junctions, with the battery housed inside the aluminium chassis.
Ready for more than the trail
The removable accessory mounting kit is included with Urrun. Use it to fit compatible accessories for more practical rides, or remove it for a cleaner mountain-bike setup. The mounting kit is part of the bike; a rack, mudguards, stand and lights are separate choices.
