Introducing our all-new ACE-S PRO Dual Suspension Fat Tyre Electric Bike, the latest innovation from Ampd Bros that redefines what a fat bike can do.
Designed for the adventurer who demands performance, comfort and style, the ACE-S PRO boasts a revolutionary singular DNM Rear Suspension Shock, setting it apart from the competition. This groundbreaking design allows for seat height adjustment — a feature never before seen in fat bikes — while providing an ultra-smooth ride. The step-through frame adds ease and accessibility, making it ideal for all riders, regardless of height or mobility.
At the heart of the ACE-S PRO is a powerful Bafang Rear Hub Motor, delivering a whopping 95Nm of torque for unmatched performance on any terrain. Whether you're cruising along the beach, tackling steep hills or gliding over dirt trails, this bike ensures a seamless ride every time. Paired with Ampd Bros’ signature GEN3 Aluminium Battery, featuring Premium Samsung 21700 cells that are 30% larger and more energy dense than any other brand giving the bike a generous 100km range, ensuring that your adventures are only limited by your imagination. The battery also includes an integrated tail and brake light for enhanced safety.
The ACE-S PRO’s cutting-edge suspension system is a game - changer. Unlike traditional twin rear shocks used on other brands, which are bulky and outdated, the singular DNM shock not only looks sleek but also delivers superior performance. With 100mm of seat height adjustment, you can tailor your ride for optimal comfort, whether you're tackling rough trails or commuting through the city.
