Powerful but Heavy

Crazy power - hits 45mph no problem. Great for trails. The only downside is the extra weight from the battery. Still, totally worth it!

5. Is this kit suitable for off-road use?
Absolutely. This kit is optimized for both on-road and off-road use, with durable components to withstand rough terrains. The 80Nm torque output provides strong hill-climbing power, while the brushless direct drive motor ensures smooth and efficient operation over rocky trails and steep inclines. For safety, we recommend ensuring your bike frame is sturdy and installing the included torque arm for extra stability.

6. The kit comes with a variety of essential accessories to support installation and maintenance: - Brake Sensor: Allows safe braking by cutting off motor power when engaged. - Torque Arm: Adds strength to your bike frame to handle the powerful motor. - ECMF (Electronic Control Management Fuse): Helps protect the motor and electrical components. - Tool Kit: Includes wrenches and tools for easy installation and adjustments.

This protection allows you to ride in rainy or wet conditions without worrying about damaging the electrical components. However, it’s advisable to avoid fully submerging the components in water.
9. How long will the battery last?
The battery is built for long-term reliability, with a lifespan of up to 800 charge cycles. Under typical use, this translates to around 3 years of performance before any noticeable capacity reduction. Smart power management features also help extend battery life by regulating output based on usage and conditions.
10. What kind of maintenance does this kit require?
The Kirbebike kit is low-maintenance, thanks to its robust and high-quality components. Basic maintenance involves keeping connections clean and tight, checking the battery status regularly, and ensuring proper tire pressure to optimize range and performance.
