Import Electric Bicycle Conversion Kit Qd-S002b — Buy in Bulk from Supplier in China

The Electric bicycle conversion kit QD-S002B is a front‑wheel conversion solution that replaces the standard hub with a brushless geared motor, allowing a conventional bicycle to run on electric power. The kit supplies a complete set of components including the motor, mounting brackets and step‑by‑step installation instructions, and it is engineered to fit a broad selection of adult bicycles with 26‑28 inch wheels. Compatibility information is provided by the supplier, and the kit carries the supplier’s quality certifications for safety and reliability.

In the e‑bike market a front‑hub motor of this type is typically rated at 250 W, which meets many regional speed‑limit regulations. Standard e‑bike builds also use a 36 V lithium‑ion battery and a matching controller, both of which are common across conversion kits and give a practical range of 40‑60 km per charge. Typical torque output for a high‑torque hub motor is around 50 Nm, enabling confident hill climbing and smooth acceleration. These industry norms help buyers compare the QD‑S002B against other conversion options.

The kit is suitable for individual commuters, bike‑share operators and small retail workshops that want to offer an electric upgrade without investing in fully built e‑bikes. Trade terms mentioned by the supplier include flexible minimum order quantities, FOB or CIF shipping from Chinese ports, and payment by L/C or T/T. Prospective buyers should ask the supplier to confirm the exact MOQ, lead time and any additional documentation required for customs clearance before placing an order.
