The OEM 5000W ebike kit is a high-power conversion system designed to transform standard bicycles into electric speed machines. It features a robust motor, advanced controller, and customizable battery options, delivering speeds up to 50+ mph. Ideal for off-road enthusiasts and commuters seeking extreme torque, this kit prioritizes modularity, durability, and compatibility with most bike frames.
How Does the Segway XYBER Compare to the Sur-Ron?
How Does the 5000W Motor Compare to Lower-Powered Ebike Kits?
The 5000W motor outperforms standard 250W-1000W kits with 300% more torque, enabling hill climbs up to 45° gradients and acceleration rivaling gas-powered motorcycles. Unlike entry-level kits, it uses a 3-phase brushless DC design with liquid cooling options, sustaining peak performance without overheating during extended high-load use.
When comparing acceleration metrics, the 5000W motor achieves 0-30mph in 3.2 seconds versus 8-10 seconds for 1000W systems. The advanced stator design features 0.35mm silicon steel laminations, reducing eddy current losses by 18% compared to conventional motors. Professional riders appreciate the dual Hall sensor configuration that maintains precise rotor positioning even at 1200 RPM rotations. For technical maintenance, the modular gearbox allows easy access to planetary gears without full disassembly – a critical advantage over sealed mid-drive units.
| Power Rating | Max Torque | Peak Efficiency | Cooling Method |
|---|---|---|---|
| 5000W | 350Nm | 92% | Liquid/Passive |
| 1000W | 95Nm | 85% | Passive Only |
How Long Does the Battery Last Under Maximum Power Draw?
Using a 72V 30Ah battery at full throttle (90A discharge), runtime is 18-22 minutes. However, eco-mode extends range to 45 miles at 25mph. The system supports dual-battery configurations through parallel connections, doubling capacity. Samsung 40T 21700 cells are recommended for sustained 100A bursts without voltage sag.
Advanced users often implement hybrid battery configurations using primary and auxiliary packs. Through the controller’s priority charging algorithm, the system automatically switches between battery sources based on voltage thresholds. Field tests show that running dual 72V20Ah batteries in parallel provides 35 minutes of continuous WOT operation while keeping individual cell temperatures below 60°C. For optimal performance, battery maintenance requires monthly balance charging and storage at 50% charge in temperatures below 40°C.
“The OEM 5000W platform bridges the gap between ebikes and light electric motorcycles. Its true innovation lies in the modular controller architecture—professionals can stack multiple units for 15,000W+ drag racing builds. However, users must prioritize frame reinforcement; we’ve seen 3mm steel dropouts shear under repeated 0-40mph launches.”

FAQ
- Q: Does the kit include regenerative braking?
- A: No—direct drive motors required for regen aren’t compatible with this geared hub design.
- Q: Can I use solar charging?
- A: Yes, through MPPT controllers supporting 72V input, but full recharge requires 6+ hours at 1000W solar input.
- Q: Warranty duration?
- A: 6 months on motor/controller, excluding water damage or overvoltage misuse.
The OEM 5000W ebike kit redefines electric bicycle performance, offering motorcycle-level acceleration and hill-climbing capabilities. While requiring technical expertise for installation and legal awareness for operation, its industrial-grade components and customization options make it the ultimate choice for adrenaline-seeking riders and technical enthusiasts pushing ebike engineering boundaries.
