The 2025 Specialized Turbo Tero 4.0 Step-Through EQ Electric Trekking Bike is an adventure-ready suspension electric bike. This is Specialized's go-anywhere, over anything, with everything vehicle. Plus, with enough storage space to pack in a few backcountry comforts, you'll discover new adventures easier than ever. The Step-Through frame makes it easier to get on and off the bike, especially when it is fully loaded.
The Tero 4.0 comes with a Turbo Full Power 2.0 Motor and 710 Wh Battery integrated into the aluminium frame. They effectively quadruple your own power, cranking out ample wattage to make short work of the steepest climbs and providing enough extra muscle to let you carry a mountain of adventure gear, groceries or kids.
The Tero comes with lots of mountain bike focussed parts. Aggressive but smooth rolling 29” wheels with 2.3” Ground Control tyres offer ample traction in every situation, SRAM disc brakes deliver substantial braking bite, 110 mm of front suspension travel smooths the trail, and a dropper seatpost is there for when you need it in technical off-road situations.
Want a commuter you can take touring? A touring bike that can haul cargo? This is it. Off-road capable wheels and tyres, powerful hydraulic disc brakes, and a full-on suspension fork can transform every ride into an adventure, whether you’re on dirt roads or cruising through the concrete jungle.
