How Cog works

The global marketplace for bikes and cycling components — built for cyclists, by cyclists.

Buying

Browse thousands of listings or use the search bar to find a specific bike, frame, or component. Filter by category, condition, price, and more.

Click Buy now to purchase immediately at the listed price, or Make an offer to negotiate. Sellers have 48 hours to accept or decline.

All payments go through Stripe — your card details are never stored by Cog. Payments are held securely until the item arrives.

The seller ships directly to you. If the item isn't as described, contact us within 3 days for a full refund under Cog Buyer Protection.

Click + Sell and fill in the details — title, category, condition, price, and up to 8 photos. Good photos and accurate descriptions sell faster.

Buyers can make offers or purchase outright. Accept, decline, or let them expire from your dashboard.

Once a buyer pays, funds are released to you minus Cog's 5% platform fee. Payments are processed within 2–5 business days.

Package the item carefully and ship within 3 days of a sale. Upload the tracking number so the buyer can follow delivery.
