The urban mobility landscape is evolving rapidly, and the electric bicycle has become the vehicle of choice for city dwellers seeking a cost-effective, healthy, and enjoyable way to navigate traffic-clogged streets. Standing out in a crowded market of generic e-bikes, the Kuiperbelt S1 positions itself as a premium, intelligently designed solution. With a focus on high-quality components like a torque sensor, a BAFANG motor, and an LG battery, it promises a refined and powerful riding experience tailored for the modern commuter.
Let’s delve into the features that make the Kuiperbelt S1 a noteworthy contender in the world of urban e-bikes.

Designed for the City: Form and Function
The Kuiperbelt S1 features a sleek, modern 20-inch folding frame that strikes a perfect balance between compactness and stability. The folding mechanism is a key advantage, transforming the bike into a manageable size for easy storage in apartments, offices, or on public transport. This makes it an ideal solution for those with mixed-mode commutes or limited living space. Despite its foldable nature, it boasts a impressive maximum load capacity of 150 kg, ensuring it can accommodate a wide range of riders and their cargo.
The Heart of the Ride: BAFANG Motor and Torque Sensor
Many entry-level e-bikes use cadence sensors, which simply provide power when you pedal, regardless of how hard you’re pushing. The Kuiperbelt S1 elevates the experience with a torque sensor. This advanced system measures the actual force you apply to the pedals and provides proportional motor assistance. The result is an incredibly natural and intuitive riding feel that mimics the sensation of having super-powered legs. It delivers power exactly when you need it, especially useful for accelerating from a stop or climbing inclines, making for a smoother and more efficient ride.
Paired with this smart sensor is a reliable 250W BAFANG rear hub motor. BAFANG is a respected name in the e-bike industry, known for producing durable and efficient motors. This motor provides ample power for urban terrain, offering quiet and responsive assistance to conquer hills and extend your range without breaking a sweat.

Go the Distance: LG 21700 Battery and Impressive Range
Powering the S1 is a high-quality 48V 15Ah battery utilizing LG 21700 cells. LG is a top-tier brand known for its high energy density and long-lasting performance. The 21700 cell format is a newer, more efficient standard than older 18650 cells, offering better capacity and longevity. This premium power source is the key to the bike’s claimed maximum range of 115 km (over 70 miles) on a single charge.
While real-world range will always vary based on rider weight, terrain, assist level, and weather, starting with a high-capacity battery from a reputable manufacturer like LG means you’re getting the best possible foundation for long, reliable journeys.
