Test and review of the new Giant Trance Advanced E+ 2027: SyncDrive Pro 4 48V motor (120 Nm), 840 Wh battery, 21.9 kg weight, and Maestro suspension.
⚡ THE 3-LINE SUMMARY (For those in a rush)
Disruptive Specs: The new SyncDrive Pro 4 48V motor throws down 120 Nm of torque and 850W of peak power, with a lightning-fast response time of just 0.28 seconds.
Weight Defying: Despite housing a massive 840 Wh integrated battery, the top-tier Trance Advanced E+ 0 tips the scales at a mere 21.9 kg.
Tailored Kinematics: The frame and Maestro suspension layout were designed in complete synergy from day one, avoiding the geometric compromises typical of standard motor mounts.
When a brand like Giant drops technical specs of this magnitude, the e-mountain bike community instantly splits between chronic skeptics and wide-eyed optimists. The new Giant Trance Advanced E+ (2027) hits the market with a jaw-dropping business card: 120 Nm of torque, 850 Watts of peak power, an 840 Wh accumulator, and a total weight of just 21.9 kg.
These numbers on paper scream "ultimate e-MTB." But our job is to look past the glossy brochure: we put this new 48V platform through the wringer to see if the high-tech engineering translates to real-world trail fun or if it's just another high-end flex.
1. SyncDrive Pro 4 48V: Surgical Response or Uncontrollable Power?
The true generational leap isn't just raw wattage, it's how that power is delivered. The new SyncDrive Pro 4 48V was codesigned with the frame from the ground up on CAD, and the figures speak for themselves:
Instant Engagement: The 120 Nm of torque are available right from 0 rpm, with latency slashed to just 0.28 seconds. This means the power engages the split-second your foot touches the pedal, wiping out lag on steep, technical punchy climbs.
850W Peak Power: A beefy, sustained muscular support across the entire cadence range that doesn't choke out at high revs.
Advanced Traction Control: Unleashing 120 Nm over slick surfaces or loose scree can easily turn into a wheel-spin nightmare. Here, the software steps in to modulate delivery in real time, locking your rear tire to the earth even when grip plunges to zero.
2. Geometry & Maestro Suspension: The End of Compromises
The original sin of many full-power e-MTBs is the sheer bulk of legacy motors, which forces engineers to butcher pivots and ruin rear-end kinematics.
Giant took the harder, correct path: they engineered the motor housing around their time-tested Maestro dual-linkage layout. Under stress, the rear suspension stays active and sensitive, doesn't lock up under braking, and eats consecutive hits without blowing through its travel, delivering that active riding feel you need when descents get rowdy and technical.
3. The Ultimate Reality Check: Are 21.9 kg with 840 Wh Real?
The Achilles' heel of muscle-bound e-bikes has always been the sluggish "freight train" effect caused by heavy, awkwardly placed batteries. Hitting 21.9 kg on a full-power rig packing an 840 Wh battery is a remarkable milestone, achieved through obsessive carbon frame diet-planning and high-density cell packaging.
When you throw it into tight, twisty switchbacks and slow technical features, the bike refuses to drag that heavy inertia typical of old-school electric heavyweights. The front end lifts naturally, pushing the Trance's agility remarkably close to a high-end acoustic trail bike.
Pros, Cons, and the Skeptic's Verdict
The Real Pros (Approved)
Weight-to-Range-to-Power Ratio: Packing 840 Wh and 120 Nm into under 22 kilos is top-tier engineering.
Lightning-Fast Response: The SyncDrive Pro 4's 0.28-second latency radically transforms technical step-ups.
Suspension Performance: The integrated Maestro setup bypasses geometric compromises despite the motor punch.
The Cons (What Doesn't Convince)
Closed Ecosystem: The tight synergy between proprietary hardware and Giant's software means you'll need specialized service centers for advanced diagnostics.
Prohibitive Price: Securing top-tier carbon technology and high-end parts requires a serious financial investment.
Frequently Asked Questions (FAQ)
1. Is the 120 Nm motor hard to control on wet trails?
It takes a brief adjustment period if you're coming from milder motors, but the millimeter-precise intervention of Traction Control and the 0.28-second response help you meter power cleanly without losing rear wheel traction.
2. Does the large 840 Wh battery compromise tight cornering?
Despite the massive energy capacity, mass centralization and the overall weight drop to 21.9 kg keep the center of gravity low, successfully dampening the pendulum effect during rapid direction changes.
3. Is it manageable for riding with the motor turned off?
While built to obliterate massive elevation gains using assist, its lower weight compared to legacy standards makes unpowered pedaling significantly less painful, though it remains a substantial e-MTB platform.
The No-Filter Verdict from Cyclonline.com
"The new Giant Trance Advanced E+ (2027) raises the bar for what we can demand from a full-power e-MTB. Marrying 120 Nm, record-breaking battery life, and a 21.9 kg weight proves technology has taken massive strides. If you want a rig that flattens the steepest climbs without turning into a brick when pointing downhill, the substance is all here. You'll just have to stomach a price tag that—bet on it—will spark plenty of rider debates."
