A **72V 3000W** electric bike (or scooter) conversion kit is a high-power system designed for speed and performance. Here’s a breakdown of what you need to know:
**Components of a 72V 3000W Kit:**
1. **Motor**
– Typically a **brushless DC hub motor** (either geared or direct-drive).
– Rear-wheel or front-wheel mounting options.
– Rated for **3000W continuous**, with peak power higher (e.g., 5000W+ under acceleration).
2. **Controller**
– **72V-rated**, often **50A-60A** current output to match 3000W power.
– Some kits include **programmable controllers** for speed/acceleration tuning.
3. **Battery**
– **72V lithium (Li-ion/LiFePO4)** recommended (lead-acid is possible but heavy).
– **Capacity**: ~20Ah-30Ah for decent range (30-50+ miles depending on usage).
– Must support **high discharge rates** (e.g., 50A+ continuous).
4. **Other Parts**
– Throttle (thumb or twist grip, often with **variable speed control**).
– Brake levers (sometimes with **regenerative braking**).
– Display (shows speed, battery level, error codes).
– Wiring harness, connectors, and sometimes a **torque arm** for motor stability.
