01 WHAT THIS PRODUCT IS & ROAD RULES
Dualtron Sonic Model A Alien (Dualtron Thunder 4)
Dualtron Sonic Model A Alien (Thunder 4)
The Dualtron Sonic Model A Alien is the Thunder 4 platform: 110 km/h capability, a 2,880 Wh battery and CBS-linked 4-piston hydraulic brakes. One of the most powerful scooters Dualtron has ever built.
PRIVATE LAND / PERFORMANCE SPEC
High-power performance machine exceeding Irish statutory limits (over 400W continuous motor power or 20 km/h speed threshold). Intended strictly for private land, closed racing circuits, or export. Strictly prohibited on public roads, cycle lanes, Dublin Bus, Luas, DART, and Irish Rail. Strictly ineligible for Bike to Work scheme tax relief.
02 KEY SPECIFICATIONS & NUMBERS
01 MOTOR SYSTEM & POWERTRAIN High-Performance Electric Motor
High-output brushless hub motor configuration paired with high-amperage sine-wave controllers. Delivers explosive instant torque for steep hill climbs, off-road trails, and closed-circuit acceleration.
Every motor harness, phase wire connection, and controller hall sensor is tested and calibrated by lead technician Patrick Murphy at 157 Capel Street prior to dispatch.
02 TOP SPEED & SPEED PROFILES Private Land Specification
Multi-speed selectable throttle mapping with configurable speed tiers. High-speed stability supported by wide deck stance and optional hydraulic steering dampers.
Certified EN 1078 full-face or commuter helmet and protective riding gear are strongly advised on all journeys.
03 BATTERY PACK ARCHITECTURE & CELLS (V, AH, WH) Certified Lithium-ion Battery Pack
High-capacity certified Lithium-ion battery pack with intelligent Battery Management System (BMS). Features overcharge cut-off, thermal run-away monitoring, low-voltage cutoff, short-circuit protection, and passive cell balancing.
Charge at room temperature indoors. Never charge immediately after riding in cold weather or heavy rain; allow the pack to acclimatise for 30 minutes.
04 REAL-WORLD RANGE (ECO VS REAL COMMUTE) Up to 70 km (Eco Mode)
Eco benchmark is tested in controlled laboratory conditions (flat terrain, 65 kg rider, calm ambient wind). Real Dublin commuting accounts for frequent junction stops along Capel Street and the Quays, headwind, cold autumn/winter air temperatures, and rider payload.
05 BRAKING SYSTEM & ENERGY RECUPERATION Dual Braking System
Precision dual braking system with electronic regenerative motor braking (E-ABS). Re-routes kinetic stopping energy back into the battery pack while preventing wheel lockup on wet Irish tarmac.
Lifty Labs maintains full stocks of genuine replacement brake pads, mineral oil bleed kits, and replacement rotors at 157 Capel Street.
06 SUSPENSION & RIDE DAMPING Dual Spring / Damping Suspension
Absorbs aggressive road chatter, potholes, cobblestones, and kerb transitions across urban Dublin streetscapes. Ensures firm tyre contact with the road surface for maximum traction.
07 WHEELS, TYRES & PUNCTURE RESISTANCE 10" Tyres
Engineered with reinforced multi-ply casing to resist glass shards and sharp gravel commonly encountered on city streets. Split-rim or tubeless bead design allows straightforward tyre changes.
Punctured in Dublin? Drop your wheel into 157 Capel Street for same-day inner tube or tubeless tyre replacement by Patrick Murphy.
08 WEIGHT, PORTABILITY & CHASSIS 30 kg
Constructed from high-tensile aviation-grade aluminium alloy with robust folding stem latching mechanisms. Designed to eliminate stem play and wobble while offering practical folding for car boots and home storage.
09 IRISH LEGAL CLASSIFICATION & TRANSIT RULES PRIVATE LAND
Machines exceeding 400W or 20 km/h cannot be legally operated on Irish public roads or cycle tracks under S.I. 199/2024. Permitted strictly on private land with landowner consent or on closed racing courses.
All e-scooters (including folded models) are strictly prohibited on Dublin Bus, Luas trams, DART, and Irish Rail services across Ireland. E-scooters are strictly excluded from the Bike to Work tax relief scheme.
10 WEATHERPROOFING & IP RATINGS IP54 Splash Resistant
Protected against road spray, wet pavement mist, and dust. Electronic displays and throttle units are sealed with internal silicone gaskets.
For torrential Irish winter downpours, puddle immersion, and road salt protection, upgrade to our certified Lifty Labs Stage 2 IPX6 Japanese Super Sealant Weatherproofing service (€199) applied at 157 Capel Street, Dublin 1.

Irish Weather Protection Upgrades
Irish commuting is famous for sudden downpours and road puddle spray. We provide two levels of precision workshop weatherproofing sealed by Patrick Murphy at 157 Capel Street:
Standard manufacturer warranties do NOT cover water damage. Only our Stage 2 IPX6 Weatherproofing (€199) protects your warranty against wet Irish weather. (Protection is strictly capped at Stage 2 IPX6; no e-bike or e-scooter is 100% submersible underwater).
05 WARRANTY COVERAGE & DELIVERY RATES
PERFORMANCE E-SCOOTER WARRANTY
- 2 Years on Frame: Full coverage on the aluminium frame and folding mechanism.
- 1 Year on Motors & Battery: Motor coils and lithium battery cells covered against faults.
- 6 Months on Electronics: Throttle, screen, and controller covered.
- Water Note: Water damage requires Lifty Stage 2 IPX6 weatherproofing.
06 SIMPLE QUESTIONS & ANSWERS (FAQS)
No. Because this high-performance scooter exceeds statutory thresholds (over 400W continuous power or 20 km/h speed limit), it is restricted strictly to private land, closed racing tracks, and export.
No. Under National Transport Authority (NTA) regulations enacted in October 2024, all electric scooters (including folded models) are strictly prohibited on all public transport across Ireland.
No. Under Irish Revenue statutory regulations, electric scooters and unicycles are strictly ineligible for the Bike to Work tax relief scheme (which applies only to pedal bicycles and EN 15194 pedelec e-bikes).
Factory ratings protect against light rain and splashes. For daily commuting through heavy Dublin downpours and road puddles, we strongly recommend our Lifty Labs Stage 2 IPX6 Japanese Super Sealant Weatherproofing service (€199) applied by Patrick Murphy at 157 Capel Street.
