bianchi fully e mtb Bianchi E-Oltre Ultegra Di2 Bike

Most e-road bikes make their presence known before you've even thrown a leg over them — oversized down tubes, visible battery housings, a center-mounted motor that shifts weight exactly where you feel it most in corners and on sustained climbs. The Bianchi E-Oltre Ultegra Di2 Bike starts from a different premise: that an electric road bike should ride like a road bike, and that the motor's job is to keep you on pace with a faster group, push deeper into a long ride, or bring riders of different fitness levels onto the same roads without either one waiting at the top.

The foundation is Bianchi's Oltre e-road carbon frame — the same platform that underpins the brand's non-electric road lineup. Internal cable routing runs throughout the frame and fork. The front fork uses a 12x100mm thru-axle with flat-mount disc brake tabs, and the bottom bracket is pressfit. Nothing about the geometry or the tube shapes announces that you're looking at an electric bike. At just over 12 kilograms fully built, the E-Oltre comes in substantially lighter than most complete e-road builds at this price point.

The Mahle X30 motor integrates into the rear hub rather than the bottom bracket — the detail that most defines how the E-Oltre rides. Hub-mounted weight sits low and rearward, close to where it would sit on a conventional rear wheel, so the bike's handling stays predictable in corners and during out-of-saddle efforts on climbs. The 250W, 40Nm drive unit activates through a torque sensor embedded in the bottom bracket shell. It reads your pedaling force, not just your cadence, and translates proportional assistance back through the drivetrain. Push into a climb, the motor builds with your effort. Back off, it fades proportionally. The assistance follows your input rather than imposing a fixed boost, which is what keeps the ride from feeling motorized.

The 250Wh Mahle iX battery integrates cleanly into the frame and is designed to provide up to 90 kilometers of range under typical riding conditions. An optional range extender module can add up to 55 kilometers more for bigger days on the road. Three assistance levels are adjustable on the fly through the Mahle iWoc ONE head unit — mounted on the stem face — or directly from the integrated e-shifter buttons on the bars, keeping motor control within thumb reach without moving your hands off the hoods. The system connects via ANT+ and Bluetooth for pairing with a cycling computer or the Mahle companion app, where individual assist levels can be customized to your preference.

Shifting is handled by Shimano Ultegra Di2 12-speed electronics — FD-R8150 front derailleur, RD-R8150 rear — driven by Ultegra R8170 STI levers that integrate braking, shifting, and motor assist controls in a single interface. The crankset is a Shimano Ultegra FC-R8100 HollowTech 2 in 50/34T, a compact double well-suited to varied terrain. A Shimano 105 12-speed cassette running 11-34T covers a wide enough spread to handle relaxed tempo riding on the flats and sustained climbing without spinning out. Shimano Ultegra R8170 hydraulic disc calipers handle stopping, paired with a Shimano MT800 Centerlock 160mm rotor at the front and an RT86 6-bolt 160mm at the rear.

Velomann Plutonium carbon wheels at 50mm rim depth come spec'd from the factory. The rear wheel runs 32 spokes — eight more than the 24-spoke front — to meet the structural demands of the hub-mounted motor while maintaining lateral stiffness. Both rims are tubeless ready and roll on Vittoria Rubino V G2.0 TLR 700x28c tires. The cockpit pairs a Velomann alloy stem with full internal cable routing — Acros AICR compatible — to the Velomann Aero Compact handlebar in 74mm reach and 116mm drop. Bar width runs 400mm on the three smaller frame sizes and 420mm on the 55cm and up. The carbon aero seatpost uses an adjustable alloy head with ±35mm of setback range.

Bianchi has been building bicycles since 1885, one of the oldest continuous bicycle manufacturers in existence, and the E-Oltre carries that history in the brand's signature Celeste Metallic / Graphite / CK16 finish. The Celeste color has appeared on Bianchi bikes for well over a century and remains one of the most recognizable paint schemes in road cycling. Seven frame sizes run from 47 to 61cm, with head tube length, reach, and stack scaling proportionally across the range.
