[KAISDA K201 – All‑Round Dual‑Battery Electric Assist Bike]
Opening Summary
The KAISDA K201 is built for female riders who seek freedom and fun, combining the stability of a fat‑tire snow bike with the convenience of urban commuting. The dual‑battery system, powerful assist, and solid construction let you enjoy a long‑lasting, worry‑free ride – whether through city streets, along sandy beaches, or across snowy trails.
-
Dual‑Battery Long Range – Say Goodbye to Range Anxiety
The K201 features a concealed 10.4Ah battery plus a rear‑mounted 10.4Ah battery, delivering a total energy capacity of 748.8Wh. In pure electric mode, it offers a range of 70‑80 km (at 25 km/h); in pedal‑assist mode, the range extends to 80‑90 km – meeting the demands of long‑distance travel. The batteries maintain high efficiency even after 1,000 charge‑discharge cycles, and with an intelligent BMS protection system, they are safe and durable.
-
Smart Assist System – Speed at Your Fingertips
It offers 1‑5 levels of pedal assist plus a pure throttle mode – Level 1 for gentle, energy‑saving riding, and Level 5 for powerful performance. The top speed is strictly capped at 25 km/h (compliant with national standards), ensuring both safety and efficiency. The centrally mounted LCD display clearly shows battery level, assist level, and mileage, while the USB port allows emergency charging for your phone – keeping all ride data visible at a glance.
-
All‑Terrain Adaptability – Comfortable Riding Experience
20×3.0‑inch CST wide tyres paired with an aluminium alloy frame handle mountains, flats, snow, and sand with ease. Mechanical disc brakes (180 mm rotors) deliver responsive stopping power, and the front and rear kickstands ensure stable parking. The saddle height is adjustable from 84‑100 cm, fitting riders 155‑180 cm tall, and the leather‑foam saddle reduces fatigue on long rides.
-
High‑Quality Components – Craftsmanship in Every Detail
Shimano derailleur and 7‑speed freewheel provide smooth transmission; the KMC chain and integrated bottom bracket are built for durability. The LED headlight (German standard) and brake taillight enhance night‑time safety, while practical features including full plastic mudguards and a rear rack come as standard. The whole‑vehicle waterproof wiring harness is designed to operate in temperatures from ‑10°C to 45°C.
-
Portable and Easy to Store – Lightweight Design
With a net weight of 33 kg and folded dimensions of just 92×46×114 cm, the K201 fits easily into a car boot. The main aluminium alloy frame is finished in sleek black, and the package dimensions of 140×26×74 cm facilitate convenient logistics and transport.
