Inspired by the MiniMODs Single Spoke EZwheels

Launched in early 2025, the Single Spoke Knob Hinge Clamp carries the same clean, elegant, and minimalist aesthetic that defines the MiniMODs brand. The design is both functional and visually striking, making it the ideal companion for the MiniMODs Single Spoke EZwheels, MiniMODs X-Roller Extender, and MiniMODs Adjustable Front Carrier Block.

Key Design Features

• Single Spoke design — Stylish and perfectly paired with Single Spoke EZwheels.

• ‘Petal’ base design — Four subtle protrusions provide better grip, allowing the knob to turn smoothly and lock securely with a final twist.

• Reverse thread screw — Prevents the stop screw from loosening when the knob is turned.

• E-circlip on hinge plate — Keeps the plate in place, enabling one-handed operation.

See-Through Safety Window

A MiniMODs innovation, the hinge plate features a first-of-its-kind see-through safety window. This lets riders quickly check whether the safety gap between the hinge and hinge clamp plate is at least 0.90 mm (per Brompton’s user manual). If the gap is smaller, the hinge plate should be replaced for safety. This feature makes inspections easy, fast, and reliable.

Strength & Compatibility

Made of durable alloy and fully reinforced, the enclosed hinge plate ensures long-lasting performance. It is also fully compatible with the original Brompton Hinge Clamp Lever and sold as a pair.
