Cheap Plastic Bicycle Cup Holder – Bulk Supply

This component provides a simple, low‑cost method for securing a beverage container to a bicycle frame or handlebar. Designed for high‑volume production, the part is molded from thermoplastic polymers and can be supplied in quantities ranging from a few thousand to several hundred thousand units per order.

Material and Design Characteristics

The holder is typically made from polypropylene (PP) copolymer, selected for its balance of stiffness, impact resistance, and resistance to UV degradation when stabilized. Additives such as hindered amine light stabilizers (HALS) are added to extend outdoor service life.

Standard dimensions are approximately 85 mm length, 55 mm width, and 45 mm height, with a wall thickness of 2 mm. The part weighs about 12 grams and can support a static load of up to 15 kg without permanent deformation, as verified by short‑term flexural testing.

Key Specifications

Manufacturing Considerations for Bulk Orders

The part is produced using single‑cavity or multi‑cavity injection molding tools. Cycle times typically range from 12 to 18 seconds per shot, depending on hot‑runner design and wall thickness. Tooling life exceeds 1 million shots when proper maintenance and corrosion‑resistant steels are used.

Tolerances are held to ±0.2 mm on critical dimensions to ensure consistent fit on standard bottle diameters (65‑75 mm). A visual inspection station checks for flash, sink marks, and color uniformity before packing.

Typical Applications

Bicycle cup holders are most beneficial where riders need hands‑free hydration without adding significant weight or complexity. They are commonly installed on commuter bicycles, electric‑assist bikes, and children’s bikes where a standard bottle cage may be impractical.

• Urban commuting – allows rider to carry coffee or water bottles while navigating traffic.
• Delivery e‑bikes – provides quick access to beverage during long shifts.
• Recreational kids bikes – offers a safe, spill‑resistant container holder for younger riders.
• Folding bicycles – compact holder that does not interfere with folding mechanism.

Quality Assurance and Testing

Each production lot undergoes dimensional sampling using calibrated calipers and coordinate‑measuring machines (CMM) on a statistically significant sample size (typically 1 % of lot). Load testing is performed by applying a gradual force until deflection exceeds 1 mm, recording the failure point.

UV exposure testing follows ASTM G154 cycle, with color change and tensile retention measured after 500 hours. Parts that retain ≥80 % of original tensile strength are accepted for outdoor use.

Ordering and Packaging for Bulk

Standard packaging places 200 units per corrugated carton, with cartons stacked on pallets (typically 40 cartons per pallet). Each carton is lined with a low‑density polyethylene bag to prevent dust ingress. Pallets are stretch‑wrapped and corner‑protected for containerized shipment.

Lead times depend on tool availability and order size; for repeat orders using existing molds, a typical window is 3‑4 weeks from receipt of purchase order to ex‑factory readiness.

Frequently Asked Questions

Can the dimensions be customized to fit non‑standard bottle sizes?

Yes. The mold can be altered to adjust the inner diameter and depth; new tooling quotes are provided after reviewing the required specifications.

What information is required before a quotation can be issued?

We need the expected annual quantity, preferred material grade (standard PP or UV‑stabilized), color, any logo or marking details, and target delivery schedule.

Are there any minimum order quantities for bulk pricing?

Minimum order quantities start at 5 000 units for standard colors; lower volumes are possible but may incur setup fees.

How is quality inspected before shipment?

Incoming material is checked for melt flow index, final parts undergo visual inspection, dimensional sampling, and load verification as described in the quality section.
