The Turbo Tero X means one thing: you're going to need a bigger map. With ride anywhere range, this full-suspension electric bike is our 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 only question left to ask is where to?

POWERFUL: Pedal beyond the map with the seamless performance of the Specialized Full Power 2.0E motor and the Turbo Operating System. The Specialized Full Power 2.0E motor has been tested against the most rugged terrain, in the harshest conditions, to ensure the highest quality experience. An intelligent e-bike operating system that seamlessly integrates our fully custom, purpose-built software and hardware so you can ride farther and explore more than ever before. What’s more, the MasterMind Display provides instant tunability right at your fingertips while keeping an eye on the built-in range estimator to ensure you’re hitting maximal range and ride time. Plus, the MasterMind Display seamlessly integrates with the Specialized app to enable integrated range optimization tools, advanced tuning, on-ride diagnostics, and more.

SMOOTH: The pothole-eating, bump-smoothing, rock-flattening confidence, comfort, and control built into the Tero X tame the most rugged terrain. Thanks to ample front and rear suspension, a performance-minded upright riding position, our world-renowned Ground Control tires, and the confidence of a dropper seatpost, we’ve made it easier than ever to explore rough routes with confidence.

VERSATILE: Ride beyond the horizon with everything you need. The Tero X is equipped with up to 1,000 lumens of headlight power, up to 22 lumens of rear light illumination, and an integrated rear rack that safely carries up to 20kg of adventure gear. Oh, and did we forget to mention the extra front rack for 10kg of additional on-bike storage? Sounds like any ride is a bright idea.

The speed limit at which the motor will stop supporting may vary significantly by region and is based on local requirements. It may also affect range: a higher speed limit may result in less range.

  • Specialized Full Power 2.0E Motor with 50Nm of torque and a 530Wh Battery deliver incredible, seamless pedal assistance and long-lasting battery life. With a ride-anywhere range, go up to 68 miles (110 km) or 5 hours on a single charge (eco mode).

  • Specialized app and MasterMind display allow you to tailor Tero X’s power output levels to your desired riding preference.

  • Specialized app gives you added security by allowing you to disable the motor and activate the motion sensor alarm with Turbo System lock.

  • 130/120mm of full suspension. A lock-out equipped RockShox Recon Silver RL fork and a RockShox Deluxe Select R shock provide confidence, comfort, and control. 

  • Dropper seat post helps you stay in control during the rocky parts while making it easier to get your foot down when coming to a stop. 

  • DRYTECH stainless steel fenders ensure that no matter the adventure, you always arrive fresh. 

  • World-renowned Ground Control Grid T7 tires for unsurpassed traction. 

  • Rear rack with side pannier rails provides 20kg carrying capacity. Also compatible with the Front Rack and Adventure Plate for an additional 10kg of capacity. 

  • Integrated Lezyne Classic front light with 500 lumens and Lezyne Fender rear light. 

  • For optimal ride control, the Tero X features a front and rear wheel combination of 29/27.5, also known as a mullet setup, in all sizes except the S. The S features 27.5/27.5 front and rear wheel combinations.

Bicicleta muy versátil

Es mi primera bicicleta eléctrica. Buscaba una bici para poder salir a pasear y hacer trayectos de 80 - 100 Km para bajar mi sobrepeso, que pudiera ponerle alforjas para poder hacer pequeñas compras y poder llevar, bañador, toalla, ropa de cambio, etc. sin necesidad de llevar mochila. Con los accesorios que tiene, es una bicicleta muy completa y de muy buena calidad, si a esto le unes la app que tiene y que puedes configurarla para que te ayude con diferentes niveles de ayuda, hace que quieras ir a casi todos los sitios en bici. Lo único que veo es la parte de goma de la pata de cabra muy endeble, ya que a veces al ir cargada la alforja, esta acaba partiéndose y hay que cambiarla entera.. 20€, podían vender esta pieza suelta. Gran compra y gran precio, me esperaré a las rebajas para comprar otra de una talla menor para mi mujer.

Per chi non deve fare fuori strada estremo, direi che é il top, molto maneggevole, se tarata bene anche comoda, prodotto molto curato nei particolari e ottimo rapporto qualità prezzo.

Grips

Had my bike now for about six weeks. 230km later and it still delights. Sure footed and comfortable. I love the mudguards which I didn’t think I would keep on. Given how bad the summer is they are great. They actually add to the work horse look. Gearing is well set . I’m just getting used to the weight as this is my first e-bike. Not sure about the grips with the palm moulding. Will probably change them but it’s been a great few weeks.

Great bike when it worked

At 51 miles from new the motor switched off due to a lighting issue with the bike lights. The app gave me the codes and online support came back with the issue and told me to return the bike to supplier for repair. I've yet to get the bike back as a "claim" is going through. Can't recommend a bike that has no means of isolation on two cables feeding the lights. You get a 26kg bicycle without e, through a design fault. Buy the bike. Junk the wired-in lights and you should be good to go.

Molto versatile

Ho acquistato la Turbo Tero X 4.0 a prezzo conveniente durante una promozione. La bici è molto versatile e si comporta bene su asfalto e su sterrato non troppo impegnativo. Le luci sono molto potenti per vedere la strada anche al buio. Sospensioni e freni di qualità. Imparando ad impostare il tuning dei modi Eco, Trail e Turbo tramite l'app, si ha la giusta assistenza, senza consumare troppa batteria. Con una carica riesco a percorrere più di 120km, viaggiando a 25 km/h costanti, su strade miste tra asfalto e boschi, con poche salite (70% in Eco, 30% in Trail). L'app e il display sul manubrio offrono tutte le informazioni necessarie e sono di facile utilizzo.

Buena bici

Es una buena bici. Da lo que promete. Tiene unas suspensiones muy decentes, unos frenos a la altura, y un equipamiento completo: La tija retractil, la pata de cabra, los guardabarros, la parrilla trasera y las luces le añaden una dosis de practicidad envidiable. Sin ellas sería una bici mtb, pero sinceramente, una vez que la pruebas, no puedes prescindir de ellas. No entiendo por qué no se ven más modelos de éste tipo. Una bici para todo. Muy satisfecho con la compra.

va bene su asfalto o poco sterrato

Bici onesta fa il suo dovere ma ha una autonomia tropo bassa per me , è una bici per argini in piano , se la si usa su salite la carica non dura niente . Sett scorsa fatto 50 km su piano e 5-6 on salita sono rimasto a secco a metà giro -i restanti 30 km per tornate solo muscolare una fatica notevole . I parafanghi comodi se piove ma come entrano dei sassi te li porti in giro con parecchio rumore . Computer buono molte funzioni- Telaio non adatto per fuoristrada si sentono tutti i limiti .Consiglio solo per uso cittadino e poco di piu . Comunque una bici da 4000€ con una automia di

Ein schönes E Bike

Niemals ein E Bike so war meine Meinung. Mit einem preiswerten E Bike von einem großen Lebensmittelanbieter war ich nach 800 Kilometern enttäuscht und habe es zurückgegeben. Dann mein zweiter Versuch und auf anhieb dieses E Bike, Turbo Tero X 4.0! So etwas hätte ich nie gedacht, eine solche Verbesserung, alleine wie das Teil ohne E Motor schon fährt, Klasse. Die Bremsen sind sehr gut, die Verarbeitung und alles andere haben mich überzeugt. Ich kann dieses E Bike nur empfehlen!

Not reliable

Purchased a TeroX 3 months ago and I had already to bring it back twice to the retailer (motor and speed sensor failures). Because the retailer cannot do any repair without the input of Specialized, each of these repairs lasted 1 or 2 weeks. I already own a Levo and a Vado SL. I will consider other brands from now on. Very disappointing.
