My local pizza shop just handed me a card with their own site (and app) for ordering delivery and pickup with fewer fees and lower costs than [your-favorite-vc-funded-third-party-food-delivery-service] after I used one of those services to pick up a pizza because it was severely discounted there.
I pretty much have received the same quality of service and high fees from all of these competitors and personally have no loyalty to any one of them. It's all about the cost. If your product is cheaper with one over the other, I'll just use that.
On the bike aspect, it wasn't uncommon to see bike deliveries for Favor in Austin and Caviar in Boston.
