The Specialized Turbo Tero 4.0 EQ is one of those bikes that genuinely resists being put in a box.
Looking for a commuter you can take touring?
A cargo haulier that goes off-road?
A Specialized e-bike that does the school run on Monday and a gravel trail on Saturday?
This is it. The Tero is built for riders who refuse to compromise, and it shows in every component choice.
Power that feels like Yours
The Turbo Full Power 2.0 motor is integrated directly into the aluminium frame, and it's a smooth operator. It reads the force you put through the pedals and amplifies it up to four times, so climbs that used to hurt become something you actually look forward to.
The motor runs quietly and seamlessly, so the ride never feels mechanical or disconnected. It just feels like a stronger version of you.
Paired with a 710 Wh battery, the Specialized Turbo Tero 4.0 delivers up to 86 miles (140 km) or 6.5 hours of range on a single charge in eco mode. Loaded with gear, kids, or a week's worth of shopping, that range holds up better than you might expect.
Mountain bike DNA, ready for the real world
The Tero bike sits in a genuinely useful sweet spot: it's aggressive enough to handle rough trails, but composed enough for urban riding day in, day out.
Aggressive 29" wheels with 2.3" Ground Control tyres grip well in the wet and on loose surfaces, 110 mm of front suspension irons out the rough stuff, and SRAM hydraulic disc brakes give you the stopping power to match the speed.
A dropper seatpost rounds things off for those moments when you need to really commit off-road.
Top speed is determined by your region's local motor assistance limits, and the motor cuts out accordingly, but within those limits the Tero pulls hard and confidently.
Tuned to You, not the other way around
The Specialized app lets you dial in the three power modes to suit exactly how you ride, adjusting output to balance performance and range. MasterMind's MicroTune function takes that further, letting you tweak power in 10% increments.
Whether you want to stretch the battery on a long day or go full power through a technical section, the bike adapts.
Anti-theft that works
Press a button to disable the motor remotely. Without your personalised PIN, nobody is riding away on it. Lock the battery inside the frame or take it with you.
And through the Specialized app, you can activate a motion sensor alarm that triggers if someone so much as moves the bike. For a Specialized electric bike at this price, that peace of mind matters.
Practical by design
The Turbo Tero 4.0 EQ comes equipped with mudguards, a rack, and a kickstand as standard, rated for a thru-axle trailer and compatible with a child seat. It's the full package, genuinely ready to replace a second car for a lot of households.
