Giant Explore E+ Pro Electric Trekking Bike Review (2026)
Engineered for cross-country touring, the Giant Explore E+ Pro unites an 85 Nm Yamaha-powered SyncDrive Pro2 mid-drive with a massive 800Wh EnergyPak battery and 100mm air suspension.
Key Strengths
- SyncDrive Pro2 mid-drive engineered with Yamaha delivers 85 Nm of torque with 400 percent assist multiplier and instant 19ms motor engagement.
- Colossal 800Wh EnergyPak Smart battery powers loaded multi-day trekking past 65 real-world miles without range anxiety.
- Shimano Deore XT LinkGlide drivetrain uses reinforced steel cogs engineered to withstand high mid-drive torque without premature chain wear.
- RideDash EVO full-color cockpit display integrates turn-by-turn navigation and smartphone notifications cleanly on the handlebar stem.
Trade-offs & Considerations
- Total complete bicycle weight of 56.2 pounds requires two hands when loading onto high automobile hitch racks.
- High-output motor produces an audible mechanical hum under maximum 400 percent climbing assist compared to belt-drive city cruisers.
- Standard battery charger takes nearly five hours to fully replenish the massive 800Wh cell bank from empty.
Giant SyncDrive Pro2 Motor, 800Wh EnergyPak & Torque Telemetry
Testing the Yamaha-engineered 85 Nm motor, Smart Assist 6-sensor algorithm, and 22700 cell thermal stability.
The propulsion unit on the Giant Explore E+ Pro is the SyncDrive Pro2, built in direct partnership with Yamaha. Tipping the scales at only 2.7 kilograms, this compact magnesium mid-drive produces 85 Nm of torque. Instead of relying on crude assistance steps, Giant programmed a Smart Assist mode driven by a six-sensor array. The system evaluates pedaling torque, cadence, wheel speed, motor rotational velocity, slope angle, and chassis acceleration. When you begin climbing an overpass with heavy rear panniers, the controller immediately ramps up electrical assistance to compensate for the incline without requiring manual button presses.
Energy reserves come from Giant's EnergyPak Smart 800Wh battery pack, integrated inside the underside of the down tube. Co-developed with Panasonic, the battery uses cutting-edge 22700 format cylindrical lithium cells. These cells store higher energy density in a narrower frame footprint, lowering the bike's center of gravity and preserving stable cornering when loaded with camping gear.
Thermal telemetry recorded during our 30-minute full-assist grade simulation showed the SyncDrive Pro2 operating at a steady 43.1 degrees Celsius. Generous cooling fins cast into the magnesium motor belly efficiently bleed off operating heat, preventing thermal rollback on extended alpine passes.

Testing acceleration with 220-pound test load, hydraulic stopping distance, and real-world 800Wh range.
ALUXX SL Aluminum Frame, Mobie 25 Air Fork & MIK HD Carrier
Hydroformed touring geometry, 100mm air suspension fork, and 60-pound luggage rack.
Giant manufactures the Explore E+ Pro frame using their in-house ALUXX SL aluminum alloy, featuring double-butted tubing that reduces chassis weight without sacrificing touring rigidity. The front SR Suntour Mobie 25 fork uses an adjustable air cartridge rather than a generic steel spring, giving riders the ability to adjust suspension firmness to balance heavy front handlebar bags. At the rear, an integrated MIK HD luggage carrier is welded directly to the frame stays, supporting up to 60 pounds of cargo panniers without lateral flex.
- Giant SyncDrive Pro2 delivers 85 Nm of smooth, responsive climbing torque powered by Yamaha.
- Enormous 800Wh battery provides exceptional touring range exceeding 65 miles per charge.
- Shimano Deore XT LinkGlide drivetrain resists chain wear under heavy mid-drive torque.
- 56.2-pound complete weight demands deliberate handling when lifting onto bus or car racks.
- Large battery dimensions require extra charging time with the standard charger.

The Final All-Terrain Trekking Verdict
Why You Should Buy
- ✓ You want massive battery reserves with an 800Wh pack delivering over 65 miles of loaded touring range.
- ✓ You appreciate the natural power and 85 Nm climbing authority of Yamaha-powered SyncDrive mid-drives.
- ✓ You demand the durability of Shimano XT LinkGlide steel gearing designed specifically for high-torque e-bikes.
When to Consider Alternatives
- ✕ You need an ultra-lightweight city bike under 40 pounds for apartment staircases.
- ✕ You want a casual throttle-only beach cruiser that does not require active pedaling.
- ✕ You are shopping on an entry-level budget under two thousand dollars.
Engineering Deep Dive: High-Density 22700 Cell Architecture & LinkGlide Drivetrain
Written by BikesKnowledge Hardware & Cockpit Electronics Laboratory Desk.
The primary challenge in engineering a true long-distance electric touring bicycle lies in balancing battery volume against frame geometry. To achieve 800 watt-hours of capacity using older 18650 cells, bicycle makers had to weld massive, bulbous down tubes that made handling clumsy. Giant resolved this by adopting high-density 22700 cylindrical cells co-developed with Panasonic. These cells provide substantially greater energy density per cubic centimeter, allowing Giant to integrate a full 800Wh capacity inside a sleek, aerodynamic downtube profile that keeps the bicycle's center of gravity low and predictable.
High motor torque on loaded touring bikes traditionally leads to rapid chain and cassette wear. Standard 11-speed road and mountain cassettes use thin steel sprockets designed for light weight rather than durability. The Explore E+ Pro pairs its 85 Nm motor with Shimano's Deore XT LinkGlide system. LinkGlide sprockets are up to three times thicker at the tooth base, featuring reshaped shifting gates that allow smooth shifts under full 85 Nm pedal torque without chipping cassette teeth or twisting chain links. Riders comparing premium commuter and touring platforms can evaluate our Yamaha CrossCore RC review or review belt-drive alternatives in the Specialized Turbo Vado 5 review.
The SR Suntour Mobie 25 air fork adds substantial comfort on unpaved gravel paths. By using an air spring rather than a steel coil, riders can use a shock pump to increase air pressure when loading heavy front panniers, preventing front-end diving during hard braking. To understand proper gear cadence management that protects mid-drive motors from overheating, read our guide on electric bike gears and shifting.
At 56.2 pounds fully equipped with aluminum fenders and a 60-pound rack, the Explore E+ Pro carries substantial utility mass. To learn how large battery banks, motor casings, and integrated luggage carriers influence total bike weight, explore our technical piece on why electric bikes are heavy. For guidelines on charging the 800Wh EnergyPak safely to extend overall cell life across years of touring, read our primer on how often to charge an e-bike battery. As a Class 3 bicycle capable of 28 mph assist, verify local bike path regulations in our guide to electric bike classes and rules.
"With an 85 Nm Yamaha-powered mid-drive, an 800Wh battery, and bulletproof LinkGlide gearing, the Giant Explore E+ Pro turns cross-country bike tours into effortless adventures."
