First Look: The Orbea Urrun is a long-range electric hardtail

Urrun means “far” in the Basque language spoken where Orbea is based. Their latest offering is an electric hardtail using the same Ride Synergy (RS) tuned Shimano motor as the full suspension To go up, which limits the assistance to get more miles from the internal 540 Wh battery. Orbea says the battery will last up to eight hours of riding with up to 3,500m of climbing, which is pretty far into anyone’s book. If that’s not enough, there’s a 252Wh range extender battery, which increases range by up to 50%.

Pedal-assist hardtails aren’t necessarily the most exciting thing for purist mountain bikers, but with a starting price of €3,799 / $4,299 / £3,499 it’s probably going to appeal to a lot of people who get into sports.

Motor and Battery

Orbea’s exclusive RS motor weighs the same as this standard Shimano EP8 unit, but as it develops less peak torque (60Nm instead of 85Nm) this allows for lighter components to be used, especially in the transmission. Claimed weight of the top-of-the-line Urrun 10 in size Medium, with tubes, is 19.6 kg / 43.2 lbs. The optional range extender battery, which costs €499, weighs 1.4 kg and attaches to the water bottle holder.

As always, the range of e-bikes varies a lot depending on assist mode, riding style, terrain, rider weight and more, so most riders won’t come close to that claim of 3,500 vertical meters. But Orbea thinks the range with the internal battery should be enough for most people.

With fast-rolling tires, a smooth drivetrain, no engine friction, and relatively manageable weight, there’s nothing stopping you from riding with a dead battery.

As well as being more electron-efficient and therefore offering more range, Orbea’s other claim behind the RS-tuned motor is that it delivers its power in a more subtle and proportionate way than the standard motor, which makes it look more like a conventional bicycle.


Frame details

The Urrun uses a hydroformed alloy frame with smooth welds, similar to the To go up Hydro. Bottle cage bosses on the seat tube and down tube allow you to carry a water bottle even when using the range extender. The intact downtube saves weight, but that means removing the battery means removing the motor first and you can only charge the battery in the bike.

One thing that sets Urrun apart is the cable routing. It runs through a modified spacer just under the stem, through the headset and into the frame, so there are no unsightly cable ports behind the head tube. Unlike similar systems, the cables do not pass through the stem itself, so it is easier to swap out the stem, but the cable from the motor to the bar-mounted controller also passes through the stem and handlebar.

Electric hardtails are often used as a tool for commuting and shopping, and the Urrun’s rear axle is compatible with accessory mounts for kickstands, trailers and racks. I can see the Urrun, especially the entry-level model, appealing to people who want a bike for running to school or commuting during the week and exploring on the weekend.


Geometry

The Urrun doesn’t try to break the mold with its geometry. With a 445mm base and 66 degree head angle, it should be easy enough to maneuver at low speeds. The 74.5-degree seat angle is relatively steep by hardtail standards.
