At the heart of the bike is Specialized’s custom-tuned 2.0 motor, delivering a responsive 70Nm of torque that amplifies your pedalling up to four times. Powered by a 710Wh battery, the Tero offers long range and smooth power delivery on any route—from daily urban loops to weekend escapes. The MasterMind display allows you to control and customise your ride, including power levels and range tuning via MicroTune, all from the bars.
The frame is crafted from durable E5 aluminium, with a fully integrated battery, clean internal routing and a confident MTB-inspired fit. The SR Suntour XCR34 fork brings 100mm of suspension for smoothing out bumps, whether you're on rough trails or broken city tarmac. With wide 29x2.35" Ground Control tyres, the Tero delivers comfort, grip and control across varied terrain.
Commuters and adventurers alike will appreciate the EQ build, which includes full mudguards, a rear rack, front and rear lighting, and a sturdy kickstand. A dropper post boosts off-road performance and ease of use. Shimano’s CUES 9-speed drivetrain and hydraulic disc brakes keep gear changes crisp and braking confident, even with cargo on board.
Whether you're pulling a child trailer, packing bikepacking bags, or just heading out with full panniers, the Tero 4.0 EQ gives you the power to go further, with the handling to enjoy every mile. And with anti-theft motor lock via the Specialized app, you’ve got extra peace of mind too.
