2019 Quadro Oxygen Pros, Cons, Recalls & Verdict

✓ 5 Positive Owner Reviews (Pros)

Ultra-lightweight 93 kg curb weight makes it exceptionally agile, effortless to maneuver, and approachable for riders of any build
Large 16-inch alloy wheels easily roll over rough urban cobblestones, deep potholes, and tram lines that unsettle small-wheeled scooters
Dual removable 48V lithium-ion battery packs (~3 kWh total) can be extracted and charged indoors from any standard domestic wall socket
Silent, direct-drive electric motor delivers instant torque for zippy, zero-emission urban acceleration up to 70 km/h (L3e version)
Combined Braking System (CBS) and regenerative motor deceleration provide smooth, confidence-inspiring urban stopping power

! 5 Negative Owner Reviews & Known Issues (Cons)

Real-world riding range drops below 60 km when operated at continuous top speed or in chilly winter conditions
Underseat storage is almost completely consumed by the dual battery compartments, leaving no room for a helmet
Recharge time of 5 to 6 hours from a domestic socket requires overnight charging for daily commuter routines
Narrow step-through footboard and minimalist wind protection leave the rider exposed to inclement weather
Thin international dealer footprint following Quadro brand transitions complicates long-term parts availability

★ Editor's Technical Verdict (2019)

Developed in strategic partnership with Spanish EV specialist Torrot, the 2019 Quadro Oxygen departed from Quadro's heavyweight multi-wheelers to deliver a featherweight (93 kg), zero-emission 16-inch high-wheel city commuter. Its dual removable battery packs solve apartment charging challenges, while large wheels offer vastly superior stability over urban potholes compared to traditional small-wheeled scooters. While minimal cargo space and a modest 60–80 km real-world range restrict it strictly to short-hop metropolitan journeys, it is a delightfully nimble and eco-friendly urban tool.

Technical Overview

2019 Quadro Oxygen Technical Analysis, Chassis Review & Ownership Overview

Built around Quadro's scooter motorcycle platform, the 2019 Quadro Oxygen features a purpose-built air-cooled electric configuration. In factory specification, maximum torque reaches 35 Nm (25.8 lb-ft), transferring power to the rear wheel through a 1-speed 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 Oxygen measures 93 kg (205 lbs) wet (curb). Rider ergonomics and dimensional geometry center around a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable turn-in geometry.

Structurally, the 2019 Quadro Oxygen is built around a Steel tubes chassis with front suspension handled by Hydraulic telescopic fork and rear damping managed via Monoshock. Braking performance is delivered by double disc (220 mm rotor diameter) up front paired with single disc (200 mm) at the rear. Factory rolling stock mounts a 90/90-16 front tire and a 90/80-16 rear tire, sizing the contact patch for predictable turn-in grip and replacement tire availability.

Buyers cross-shopping the 2019 Quadro Oxygen in the Scooter segment most frequently benchmark its horsepower, seat height, and curb weight against the BMW C 650 Sport (2017), Aprilia SR Motard 125 (2017), Piaggio MP3 Hybrid 300ie (2017).
