Looking for the most fun way to get around? Look no further. The Dualtron Thunder Electric Scooter was built to perform, or should we say outperform everything in this category. For 2018 the Dualtron's suspension geometry has been completely reworked. We now have a fully adjustable 3 step variable suspension system which is coupled with replaceable rubber cartridges to completely dial in your ride. Lighter riders and riders in cooler climates will prefer softer cartridges. All Dualtron Electric Scooters come stock with medium elasticity rubber and extra cartridges are an optional accessory.
