https://electricbikereview.com/specialized/turbo-tero-4-0-eq/ The Specialized Turbo Tero 4.0 EQ is a feature-complete hardtail cross country electric mountain bike outfitted with outstanding fenders, rear rack, and integrated lights available in four frame sizes and three trim levels (3.0, 4.0, 5.0). Capable as a commuting platform and light off-road machine thanks to knobby 29er tires and high-end hydraulic brakes. Excellent weight distribution and electronics integration. Lightweight, smooth, responsive Brose motor (custom made with Specialized) offers up 70nm of torque and is highly tunable with Mission Control smartphone app. Internally routed cables stay out of the way and look great. Outstanding battery pack shape and mounting design, there’s no need for a separate cover that adds weight and complexity, removal feels safe despite exiting downwards from the downtube. Magnetic charging interface is convenient and durable, fast charger is compact and capable. TCD2 MasterMind color display can be dimmed, beeps and haptics can be disabled, you can even customize readouts or remove screens. Above-average suspension fork with 110mm travel, compression, lockout, preload, and rebound adjustability. High-visibility reflective sticker and integrated lights (which can be turned off) keep you safe. USB-C charging port on display helps maintain portable electronics. Dropper seat post makes the bike approachable and Body Geometry touch points feel great (to me). Pointy kickstand, less immediate power from standstill, front fender that clips curbs and bike racks, high price, limited availability, no equipped models in North America are the drawbacks.
