Electric bike kit is the ultimate shortcut to owning a custom, high-performance e-bike—no need for expensive pre-built models. SiAECOSYS offers a range of electric bike kits designed to simplify e-bike builds and upgrades, combining core components like mid-drive/hub motors, controllers, speedometers, and heat management tools. 
Whether you’re converting a traditional bike to electric or enhancing an existing e-bike, these kits deliver reliability, power, and ease of use tailored for e-bike enthusiasts and daily commuters.
What’s in a SiAECOSYS Electric Bike Kit?
Each kit is curated to provide a seamless, plug-and-play experience, with components optimized to work in harmony. A typical premium kit includes:
High-Power Motor: Choose from options like the QS138 4000W V3 liquid-cooled mid-drive motor (ideal for speed and hill climbing) or hub motors with compatible heat sinks (e.g., QS205 HubSink V2) to prevent overheating. Motors feature IP67 waterproofing, 72V compatibility, and peak power up to 13.5kW for robust performance.
Matching Controller: Sine-wave controllers like the EM200-2SP Votol (with enlarged heat sinks and CAN-BUS support) ensure smooth power delivery, regenerative braking, and up to 600A peak phase current—critical for stable e-bike operation.
Intuitive Display: A 6.8-inch high-resolution speedometer with Bluetooth projection, FM radio, and customizable settings (language, units, power display) keeps riders informed in real time.
Ergonomic Throttle: The Z6 throttle, with integrated reverse, parking, and 3-speed controls, simplifies rider operation and reduces the need for extra switches.
Thermal Management Tools: Optional QS205 HubSink V2 heat sinks (delivering ~200% better thermal dissipation) to keep hub motors cool during prolonged use, especially on steep hills.
Key Benefits of SiAECOSYS Electric Bike Kits
Simplified Installation: Most kits require no specialized tools—components like mid-drive motors eliminate the need for complex gearboxes or clutches.
Customizable Performance: Adjust speed, torque, and power parameters via the controller’s software; switch between lithium/lead-acid battery displays; and choose metric/imperial units to match your preferences.
All-Weather Durability: IP65–IP67 protection ratings for motors, controllers, and displays ensure resistance to rain, dust, and temperature extremes (-20°C to +70°C), making the kit suitable for year-round use.
