We're committed to building safe and reliable bikes.

Your Ride, Your Way: Groceries, backpacks, pets, or even two passengers--carry it all with ease and enjoy the convenience of riding light but living big.

Enjoy Your Family Time: a durable 6061 aluminum alloy frame, a high-quality suspension fork, and hydraulic brakes for strong stopping power on both wet and dry roads

IPX4 waterproof rating: it's not afraid of rainy days, and the spacious shelves allow parents to easily take two children to enjoy outdoor time.

With its powerful electric motor and sturdy cargo area, this bike is capable of carrying up to two children comfortably and safely. You could also carry an adult on rear rack.

The torque sensor pedal assist system measures the power you apply to the pedals and adjusts the electric assist accordingly, providing smoother acceleration, better hill-climbing capability, and improved energy efficiency. This feature makes torque sensing cargo e-bikes more intuitive and enjoyable.
