When sourcing Phoenix bicycles, the price is heavily influenced by the frame material (High-carbon steel vs. Aluminum alloy), the braking system (Mechanical disc brakes vs. V-brakes), and the drivetrain components (Shimano vs. domestic brands). For B2B buyers, it is essential to verify the welding quality (smooth vs. fish-scale welding) and the paint finish (electrostatic spraying for rust prevention). Ensure the load capacity meets your target market standards, typically 100kg to 120kg for standard adult models.
