It includes a handlebar twist throttle and mounting brackets for straightforward setup. Best for: Builders seeking a compact mid-drive option with good torque and easy mounting. Limitation: Lower voltage means lower top-end speed compared to higher-voltage kits.
NB POWER Hydraulic Brake Hub Motor
Brand: POWER. This rear motorwheel (QS 205 V3) delivers 5000W and uses a 72V Sabvoton controller with PAS and alarm options. It features a 150mm dropout and a TFT color display for monitoring. The setup is suited for riders who want integrated wheel-drive with programmable control. Best for: Riders seeking a complete rear-wheel drive solution with onboard electronics. Caution: Dropout compatibility should be verified with the bike frame to ensure proper fit.
KR5V 72V 5000W Brushless Motor
Brand: doinal Store. This high-power 72V motor peaks at 8000 RPM with 5000W, offering 35 N.m peak torque. It includes a smart temperature sensor (KTY84-130) for real-time monitoring when paired with programmable controllers. The aluminum housing with IP54 protection supports outdoor use, and a front/back or bottom mounting option increases versatility. Best for: High-performance builds needing strong power and real-time temperature feedback. Limitation: High heat load requires effective cooling during sustained use.
Buying Guide
What to consider when choosing an electric motor for a motorcycle conversion:
- Voltage and power needs: Higher voltage systems (72V) deliver more top speed and torque but require compatible controllers, wiring, and battery packs.
- Mounting style: Hub motors simplify installation on wheels, while mid-drive kits offer better balance and gearing options for torque. Check dropout widths and frame clearances.
- Cooling and weather resistance: IP ratings and heat dissipation features help ensure performance in hot or wet conditions during long rides.
- Controller compatibility: Programmable controllers enable tuning of acceleration, braking, and current limits. Ensure the controller matches motor ratings.
- Thermal protection: Temperature sensors and heat sinks prevent overheating, extending motor life on demanding terrain.
- Installation complexity: Some kits include throttles, mounting brackets, and displays, while others require additional components or custom wiring.
- Reliability and weather exposure: Aluminum housings and protective seals contribute to long-term durability in outdoor riding scenarios.
FAQs
- What motor voltage is best for a motorcycle conversion?
Voltage choice depends on your battery and controller. Higher voltages (e.g., 72V) offer more top speed and torque but require more robust components.
- Are hub motors easier to install than mid-drive kits?
Hub motors are often simpler to install on compatible wheels, while mid-drive kits may require more space and alignment but deliver better balance and gearing options.
- Do I need a programmable controller?
A programmable controller helps tailor acceleration, braking, and current limits to your riding style and terrain.
- What safety features should I look for?
Look for temperature sensors, IP ratings, and heat sinks to prevent overheating in demanding conditions.
- Can I reuse existing battery packs with these motors?
Battery compatibility is essential. Ensure your battery voltage and current capabilities are matched to the motor and controller ratings.
- What is dropout compatibility for rear hub motors?
Dropout width must match the wheel dropouts of your motorcycle. Verify measurements before purchase to avoid fit issues.
