Bulk Aluminum Alloy Bicycle Cup Holder Supplier

A bicycle cup holder secures standard 350 ml to 500 ml beverage containers to the frame or handlebar, allowing riders to hydrate without stopping. In bulk supply, the holder is produced from aluminum alloy to achieve a high strength‑to‑weight ratio while resisting corrosion from sweat and environmental exposure.

Material Composition and Mechanical Properties

The most commonly used alloy for this component is 6061‑T6, which contains approximately 0.6 % Si, 0.28 % Cu, 0.2 % Cr, 0.28 % Mg and balance Al. In the T6 temper it exhibits a minimum tensile strength of 310 MPa, a yield strength of 275 MPa and an elongation of 12 % at break.

Design Features and Dimensional Tolerances

The holder features a cylindrical cup receptacle with an internal diameter of 74 mm to accommodate standard bottles, a wall thickness of 1.2 mm for stiffness, and a mounting flange with two M5 holes spaced 30 mm apart for bolt‑on attachment.

• Internal diameter tolerance: ±0.2 mm
• Wall thickness tolerance: ±0.1 mm
• Mounting hole position tolerance: ±0.15 mm
• Surface roughness (Ra): ≤1.6 µm

Typical Applications in Cycling Industry

Beyond simple hydration, the cup holder reduces the need for riders to carry a backpack or waist pack, thereby lowering the center of gravity and improving handling on uneven terrain. Its aluminum construction also acts as a heat sink, drawing away heat from the bottle contents during prolonged exposure to sunlight.

Customization Options

• Overall height adjustable from 80 mm to 120 mm
• Cup receptacle diameter customizable between 70 mm and 80 mm
• Mounting pattern (hole diameter, spacing, thread type) can be altered to match OEM specifications
• Surface finish options include clear anodize (10 µm), colored anodize, powder coat (60 µm), or laser‑etched branding

Quality Assurance and Inspection Protocols

Each lot undergoes incoming material verification via mill test reports, followed by first‑article inspection using a coordinate‑measuring machine (CMM) to confirm critical dimensions. Subsequent production parts are checked with statistical process control (SPC) on key features, and a random sample is subjected to a 50 N pull‑out test to verify joint integrity.

Packaging and Logistics for Bulk Orders

For bulk shipments, holders are placed in recyclable polypropylene trays that hold 40 units each, stacked five trays high inside a double‑wall corrugated carton. Cartons are sealed with moisture‑resistant tape, palletized (1.2 m × 1.0 m base) and stretch‑wrapped to protect against humidity during ocean freight.

Frequently Asked Questions

• Can dimensions be customized for specific frame geometries?
  Yes, the cup receptacle diameter, wall thickness and mounting hole pattern can be adjusted based on customer‑provided CAD models or physical samples; tooling changes are quoted per project.
• What information is required before quotation?
  To generate an accurate quote we need the desired alloy temper, target dimensions, surface finish, order quantity, and any required certification (e.g., RoHS, REACH).
• How is quality inspected for large batches?
  Inspection follows the sampling plan outlined in ISO 2859‑1, with critical dimensions checked on every 200th part and mechanical testing performed on a statistically significant subset.
• What are the typical lead times for bulk orders?
  Lead time depends on tooling availability; standard configurations ship within 3‑4 weeks after receipt of purchase order, while customized designs require an additional 1‑2 weeks for tooling and approval.
