Direct Factory Kids Bicycle Cup Holder – Quotation Ready

This component is designed to attach to the frame of children’s bicycles and securely hold a standard 350 ml beverage container. The design focuses on minimizing added weight while providing sufficient retention force to prevent spillage during typical riding vibrations.

Product Overview

The cup holder consists of a molded polymer cradle, a stainless‑steel mounting bracket, and a quick‑release clamp that fits tube diameters from 22 mm to 28 mm. All interfaces are designed for tool‑free installation, allowing assembly line workers to secure the holder in under 15 seconds per unit.

Key Technical Characteristics

Material Options

• Cradle: UV‑stabilized polypropylene (PP) with 15 % glass‑filled reinforcement for increased impact resistance.
• Mounting bracket: AISI 304 stainless steel, 1.2 mm thickness, electropolished finish.
• Clamp mechanism: Nylon 6,6 with a stainless‑steel spring (wire diameter 0.8 mm) for consistent clamping force.
• Optional colorants: PP can be compounded with standard RAL pigments (e.g., RAL 5015 blue, RAL 1023 yellow) without affecting mechanical properties.

Customization Choices

• Clamp range adjustment: interchangeable inserts to accommodate tube diameters from 18 mm to 32 mm.
• Cradle depth: optional 10 mm extension for larger containers (up to 500 ml).
• Branding: laser‑etched logo on the stainless‑steel bracket (maximum line width 0.2 mm).
• Packaging: bulk trays of 100 units or individual blister packs with recyclable PET.

Typical Applications

The holder is intended for children’s bicycles aged 3 to 8 years, where riders frequently carry drinks during short trips to school, parks, or neighborhood rides. By positioning the container at the lower downtube, the center of gravity remains low, reducing the risk of handling instability compared with handle‑bar mounted alternatives.

Manufacturers of kids’ bike frames can integrate the mounting bracket as a pre‑drilled boss, allowing the holder to be snapped on during final assembly without additional tools, which simplifies inventory and reduces assembly time.

Quality Assurance

Each production lot undergoes dimensional inspection using a coordinate measuring machine (CMM) with a tolerance of ±0.15 mm on critical features such as cradle inner diameter and clamp bore. Material composition is verified via spectrometry for PP grade and stainless‑steel alloy content. Functional testing includes a vibration sweep (5 Hz to 200 Hz, 0.5 g) to confirm that the container does not disengage under simulated riding conditions.

Visual inspection checks for surface defects, flash, and color uniformity. All inspected parts are recorded in a traceability system linked to the production order number.

Packaging & Shipping

Standard packaging places 100 holders in a corrugated cardboard tray with interleaving sheets to prevent surface abrasion. Trays are stacked on pallets (max height 1.2 m) and secured with stretch film. For air freight, each tray is placed inside a double‑wall carton with corner protectors to meet ISTA 3A standards.

Marking on each carton includes part number, batch code, and quantity. Custom labeling (e.g., customer PO number) can be added upon request.

Lead Time & Sample Arrangement

Tooling‑ready parts typically ship within 15 working days after receipt of approved drawings and material specifications. Sample units (up to 5 pieces) can be dispatched via express courier within 5 working days, with shipping costs borne by the requester.

For production runs exceeding 5,000 units, the lead time extends to 20‑25 working days due to additional quality‑control cycles and palletizing.

Frequently Asked Questions

A: Yes. The clamp design uses a split‑band mechanism with interchangeable shims; we can provide custom‑machined shims to match specific tube geometries after receiving a profile drawing.

A: We need the desired quantity, material grade (standard PP or glass‑filled), clamp diameter range, any color or branding specifications, and preferred packaging (bulk tray or blister). Providing a target price range helps us prioritize options.

A: Incoming material is checked with a spectrometer; first‑article inspection includes CMM dimensions and functional vibration test. Subsequent lots are inspected using statistical sampling (AQL 0.65 for critical dimensions, AQL 1.0 for visual).

A: We support FOB Ningbo or Shanghai, CIF to major ports, and express courier (DHL, FedEx) for samples. All export shipments comply with ISPM‑15 wood‑packing regulations when pallets are used.
