360° Rotating Bicycle Cup Holder

This holder secures a standard beverage container to a bicycle frame while allowing unrestricted rotation around a vertical axis. The design prevents spillage during motion and lets the rider reposition the cup without removing the mount.

Rotation is facilitated by a pair of sealed radial ball bearings pressed into a stainless‑steel housing. Each bearing supports axial and radial loads, enabling smooth 360° turnover with a torque requirement of less than 0.2 Nm under a 0.5 kg load.

Materials commonly offered include 6061‑T6 aluminum alloy for the main body, AISI 304 stainless steel for the bearing housing, and glass‑filled nylon for the cup cradle. Aluminum provides a tensile strength of ~310 MPa with a density of 2.7 g/cm³, while the nylon cradle resists impact and retains flexibility at temperatures from –20 °C to 80 °C.

Mounting adapters are supplied as interchangeable clamps that fit frame tube diameters ranging from 25 mm to 35 mm. Each clamp uses a stainless‑steel M5 bolt with a nylon lock‑nut, delivering a clamping force of approximately 150 N when tightened to 3 Nm.

The holder safely accommodates containers up to 500 ml in volume and a maximum weight of 0.6 kg, which corresponds to a safety factor of 4:1 based on the yield strength of the aluminum arm under a static load test.

Surface treatments include clear anodizing (12 µm thickness) for the aluminum parts and passivation for stainless steel, providing resistance to UV degradation and salt‑spray corrosion per ASTM B117 testing for 500 h.

Typical applications include urban commuting, long‑distance touring, and delivery services where riders need frequent access to hydration without dismounting. The rotational feature reduces the need to adjust the bottle angle when navigating tight turns or steep gradients.

Quality control follows a three‑stage process: incoming material inspection (spectrometric verification of alloy composition), dimensional checks on critical features (±0.1 mm tolerance on bearing bores), and functional testing of rotation torque and load endurance (10 000 cycles at 0.5 kg). All units are supplied with a test report upon request.

Customization options include laser‑etched logos on the aluminum arm, alternative cradle colors (black, grey, or safety‑orange), and bespoke clamp sets for non‑standard frame sizes (e.g., oversized tubing or integrated mounts). Tooling adjustments are quoted per project based on volume and complexity.

Packaging for wholesale shipments uses double‑wall corrugated cartons with internal polyethylene foam inserts that immobilize each holder and prevent abrasion. Cartons are sealed with strapping and labeled with handling instructions; palletized loads are stretch‑wrapped for stability during transit.

Frequently Asked Questions

• Can the rotation tension be adjusted? – Yes, a set‑screw on the bearing housing allows fine‑tuning of drag between 0.1 Nm and 0.3 Nm.
• What information is needed for a quotation? – Required details include order quantity, preferred material finish, clamp diameter range, any branding specifications, and destination for freight calculation.
• Are samples available before production? – Sample units can be dispatched; the client covers sample cost and shipping, which is credited against the first production order.
