Three wheel cargo bike

When sourcing for B2B purposes, prioritize the load capacity, which should typically range between 150kg to 300kg depending on the frame reinforcement. Ensure the frame is made of high-carbon steel or reinforced aluminum alloy for a balance of durability and weight. For electric versions, look for a brushless DC motor (250W-750W) and a lithium battery (48V 15Ah or higher) with Samsung or LG cells to ensure longevity and safety. Additionally, verify the use of hydraulic disc brakes rather than mechanical ones to ensure reliable stopping power under full load.

Compliance is critical to avoid customs seizures. For the European market, the bike must meet EN 15194 standards for EPAC (Electronically Power Assisted Cycles) and carry a CE marking. For the North American market, ensure the battery pack has UL 2271 certification and the charger is UL 1310 compliant. If the cargo bike is intended for food delivery, the cargo box material must be food-grade (BPA-free) and meet local sanitation requirements.

There are two main designs: Tadpole (two wheels in front) and Delta (two wheels in back). Tadpole designs offer superior stability during cornering and better visibility of the cargo, making them ideal for urban delivery. Ensure the model features a differential gear system on the rear axle (for Delta) or a tilting mechanism (for high-end Tadpoles) to prevent tipping. Always request a stability test report or a video demonstrating the bike's performance at a full load capacity on a 15% incline.

Professional suppliers on Made-in-China.com often provide OEM/ODM services. You should negotiate for customized cargo box dimensions, insulation layers for cold-chain logistics, and integrated GPS tracking for fleet management. For branding, request UV-resistant powder coating in specific RAL colors and silk-screen printing for company logos to ensure the brand remains visible despite harsh weather conditions.

The biggest risk is shipping damage due to the large volume and weight of the product. Mitigate this by requiring SKD (Semi-Knocked Down) or CKD (Completely Knocked Down) packaging in 7-layer corrugated cartons with wooden crates. Another risk is battery degradation during long sea transit; ensure the supplier ships batteries at 30-50% charge and provides a Material Safety Data Sheet (MSDS) and UN38.3 test report for hazardous goods handling.

Use a 30% deposit and 70% balance payment structure, with the balance paid only after a successful pre-shipment inspection (PSI) by a third party like SGS or Intertek. When sourcing via Made-in-China.com, prioritize Diamond Members and Audited Suppliers who have undergone on-site factory verification. Explicitly include a 1-2 year warranty clause for the motor, controller, and frame in the Proforma Invoice (PI).

Due to the high volume, Sea Freight (FCL - Full Container Load) is the most economical method. A 40HQ container can typically hold 40-60 units in SKD form. Ensure the supplier provides a Certificate of Origin (Form E or Form F) to leverage potential Preferential Tariff treatments under trade agreements. For the final mile, confirm if the supplier can provide DDP (Delivered Duty Paid) terms if you do not have a local customs broker.
