Bigant Heavy Duty Collapsible & Stackable Plastic Milk Crate - Snap Lock Foldable Industrial Garage Storage Bin Container Utility Tote Basket (Purple, 1 Small Crate)

Fits my Tern front rack and adds so much capacity. Does reduce the usefulness of the front light but it’s still good

This is the most heavy duty consumer-grade collapsible crate (foldable container) I can find after intensive research online. This is much more reliable than other cheap ones such as the “Instacrate” from Costco, and can holder a much heavier load without breaking due it is superior design and construction. Made in Korea btw.

I zip tied this to the back of my bike and it’s perfect to leave closed until needed
