If you ride your bike to do various adventures, but could use a little more boost to go farther and faster, you might want to check out Specialized’s new Turbo Tero X (from $4,500). The new aluminum-frame e-bike that can be used for everything from hauling camping equipment, groceries, trail-building tools, or even skis. Basically, it’s an electric approach bike for getting to more remote areas with your adventure tools.

With 120 millimeters of rear travel and a 130 millimeter fork that utilizes a single-pivot suspension layout, the bike has enough travel for actual off-road riding—this is not just a warmed-over commuter bike. That doesn’t mean it wouldn’t make a great commuter, though, especially since all models have fenders, a rear rack, plus integrated headlights and tail lights. The highest end model has a 1,000 lumen front light, and a tail light that gets brighter when the brakes are applied.


The Tero X also has Specialized’s Turbo System lock, which disables the motor and sounds an alarm if the bike is moved when it’s armed. The alarm is set via the Mission Control app, the same app that can be used to customize the motor settings, record rides, and receive over-the-air system updates. Specialized does point out that a physical lock is still the best defense against theft, but it certainly doesn’t hurt to have another deterrent against thieves.


There are three models in the Tero X lineup, the 6.0, 5.0, and 4.0. The Tero X 6.0 ($6,500) uses Specialized’s Full Power 2.2 motor, which has 90 Nm of torque and is attached to a 710 Wh battery. The 5.0 ($5,500) relies on the Full Power 2.0 motor, which has 70 Nm of torque and a 710 Wh battery. The 4.0 model ($4,500) has a Full Power 2.0E motor with 50 Nm of torque and 530 Wh battery.

In Eco mode the claimed range is 68 miles with a 20 MPH/32 KPH speed limit, and a range estimator let’s you know how far you can go.

All of the bikes have a 29-inch front wheel and a 27.5-inch rear wheel for sizes medium, large, and extra large, while the size small gets two 27.5-inch wheels.
