Status: ✅ Successfully Completed
Total Development Time: 4-6 weeks
Final Cost: ₹26,000 | Estimated Market Value: ₹35,000-40,000
Description: The core propulsion system. We selected a brushless DC (BLDC) hub motor for efficiency, reliability, and minimal maintenance. The motor mounts directly in the wheel hub and converts electrical energy into rotational motion.
250W Hub Motor: ₹2,500 - ₹3,500
350W Hub Motor: ₹3,500 - ₹5,000
500W Hub Motor: ₹5,000 - ₹7,500
BLDC Hub Motor in Action - 350W, 36V System
Lithium-Ion Battery Pack - 36V 10Ah with BMS
Description: The energy heart of our project. We selected LiFePO4 lithium-ion batteries for their superior energy density, longer lifespan, and safety. These batteries power the entire system and determine the riding range.
36V 10Ah Battery: ₹8,000 - ₹10,000
36V 13Ah Battery: ₹10,000 - ₹13,000
48V 13Ah Battery: ₹12,000 - ₹15,000
Description: Smart sensors detect rider pedaling patterns and optimize motor response. We integrated cadence sensors that measure pedal rotation speed and trigger appropriate motor assistance for smooth, natural riding experience.
Cadence Sensor: ₹800 - ₹1,200
Torque Sensor (Optional): ₹2,000 - ₹3,000
Speed Sensor: ₹300 - ₹600
Cadence Sensor Detecting Pedal Motion - Real-time Signal Flow
Programmable Motor Controller - Live Operation View
Description: The intelligent control unit that manages all electrical system interactions. It regulates power flow from battery to motor, processes sensor inputs, and manages multiple assistance modes. This is the "brain" of the e-bike system.
36V Basic Controller (15A): ₹1,500 - ₹2,000
36V Standard Controller (25A): ₹2,500 - ₹3,500
48V Advanced Controller (35A+): ₹3,500 - ₹5,500
Note: Prices are approximate based on 2025 Indian market rates. Actual costs may vary based on supplier and component quality.
See how our custom-built project delivers superior value compared to ready-made market electric bicycles
Our project costs ₹26,000 vs market bikes at ₹25,000-60,000. Pay only for real components, no brand markup!
Fix any issue yourself with easily available generic parts. No expensive service center visits required.
Upgrade motor, battery, or controller anytime. Market bikes are locked to proprietary parts.
Gained hands-on experience with electronics, motors, and batteries - something no market bike can offer.
Upcycled an existing bicycle frame, reducing manufacturing carbon footprint by 60%+.
Built entirely with our hands - a true engineering accomplishment, not just a purchased product.
🎯 Final Verdict: Our DIY E-Bike wins in 12 out of 13 categories!
