The "Pro" in the name isn't just marketing. iWalk listened to user feedback from the 2019/2020 models and delivered three major improvements:
Why specify "2021"? Because iWalk has since released the KS1 Pro 2023 and 2024 editions. The differences are marginal but important:
Form Factor: The KS1 Pro features a modular "suitcase-style" design. The front face houses the control panel and LCD screen, while the sides are optimized for stacking. iwalk ks1 pro 2021
Unique Selling Point (USP) - The Expansion System: The defining feature of the KS1 Pro is its compatibility with the iWalk "KS-BP1" expansion batteries. The main unit can connect to additional battery packs seamlessly, increasing the total capacity without requiring extra wall outlets. This allows users to scale their power system from 606Wh up to roughly 2000Wh+ by daisy-chaining batteries.
Interface: Unlike many competitors that use physical buttons and monochrome LCDs, the 2021 KS1 Pro utilizes a touch screen interface. This provides a more modern user experience, allowing users to swipe between screens to view input/output wattage, remaining time, and battery percentage. The "Pro" in the name isn't just marketing
Unboxing the KS1 Pro 2021, the first thing you notice is the weight—or rather, the lack thereof. Tipping the scales at just 26.5 lbs (12 kg) , this scooter is featherlight in a market dominated by 30–40 lb behemoths. The matte black aerospace-grade aluminum frame feels rigid and premium, with zero creaks or flex. The new 2021 folding mechanism—a one-lever, secondary safety-lock system—snaps shut with a reassuring click, allowing you to carry it onto a bus, train, or up three flights of stairs with one hand.
No scooter is perfect. The KS1 Pro 2021’s small 8.5-inch wheels mean you need to scan the road ahead for cracks. Riders over 220 lbs (100 kg) will find the range drops to ~12 miles. And while the solid tires are puncture-proof, wet traction is merely "adequate"—avoid slick steel plates or painted crosswalks. Unboxing the KS1 Pro 2021, the first thing
In the fast-paced world of personal mobility, finding the perfect balance between portability, power, and price can feel like an impossible quest. Enter the iWalk KS1 Pro 2021—a third-generation electric scooter that redefines what a lightweight commuter vehicle can be. Building on the successes (and learning from the limitations) of its predecessors, the 2021 Pro model isn’t just a minor refresh; it’s a complete overhaul of the ultra-portable scooter category.
