2021 Yadea G5 Pro Pros, Cons, Recalls & Verdict

βœ“ 5 Positive Owner Reviews (Pros)
  • Powerful 3100W mid-mounted electric motor with belt final drive delivers exhilarating torque and a higher 60-70 km/h top speed
  • Dual Panasonic 18650 lithium battery packs deliver an impressive real-world urban range exceeding 100-120 kilometers
  • Large 7-inch full-color digital LCD instrument panel displays comprehensive ride telemetry, battery percentage, and clock
  • Premium motorcycle-grade hydraulic disc brakes front and rear with combined braking system (CBS) provide phenomenal stopping power
  • Minimalist European design by Beckers with high-strength cold-rolled steel frame and aluminum rear swingarm
! 5 Negative Owner Reviews & Known Issues (Cons)
  • Carries a significant price premium over standard hub-motor electric mopeds due to its mid-drive motor and dual batteries
  • Dual batteries occupy a considerable portion of under-seat storage, restricting helmet carrying capacity
  • Requires an A1 or higher motorcycle driving license in Europe due to its unrestricted >45 km/h speed capability
  • Belt drive requires occasional tension checks and inspection compared to direct-drive hub motor setups
  • Recharging dual high-capacity battery packs from empty to full takes approximately 6 to 8 hours with standard home chargers
β˜… Editor's Technical Verdict (2021)

The 2021 Yadea G5 Pro represents the flagship echelon of Yadea's electric lineup, ditching conventional hub motors in favor of a sophisticated 3100W mid-mounted motor and dual Panasonic lithium batteries. Its motorcycle-grade aluminum swingarm, expansive 7-inch digital dashboard, and swift 60+ km/h top speed provide genuine urban performance that easily outpaces sluggish 50cc-equivalent mopeds. For commuters seeking a stylish, technologically sophisticated, and high-performing zero-emissions commuter, the G5 Pro is a standout.

2021 Yadea G5 Pro Technical Analysis, Chassis Review & Ownership Overview

Engineered by Yadea for the scooter motorcycle segment, the 2021 Yadea G5 Pro features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 4.2 HP (3.1 kW) while maximum torque reaches 130 Nm (95.9 lb-ft), transferring power to the rear wheel through an automatic transmission, a direct electric drive (clutchless) clutch. Internal cylinder geometry specifies fuel delivery managed via electronic motor controller (direct electric drive).

On the scales, the G5 Pro measures 100 kg (220 lbs) dry. Rider ergonomics and dimensional geometry center around a 770 mm (30.3 in) seat height β€” offering a neutral standover height that accommodates most average-inseam riders (170–182 cm / 5'7"–6'0") without sacrificing cornering clearance and a 1,270 mm (50 in) wheelbase engineered for quick, flickable turn-in geometry.

Structurally, the 2021 Yadea G5 Pro is built around a Cold-rolled steeless frame chassis with front suspension handled by Telescopic fork and rear damping managed via Dual spring aluminium shocks. Braking performance is delivered by single disc up front paired with single disc at the rear. Factory rolling stock mounts a 90/90-12 front tire and a 100/80-12 rear tire, sizing the contact patch for predictable turn-in grip and replacement tire availability.

From a licensing standpoint, its 3.1 kW output qualifies for European A1 and beginner motorcycle license tiers. Buyers cross-shopping the 2021 Yadea G5 Pro in the Scooter segment most frequently benchmark its horsepower, seat height, and curb weight against the Yamaha NMAX (2018), Yamaha Sight (2018), Yamaha TMAX (2018).
