Is the Quick 4 Remixte good for commuting?

Yes. It has a step-through frame, rack and fender mounts, and 35c tires that roll well on pavement. The rigid fork and rim brakes are the main limits for rough roads or heavy rain.

What is the difference between the Quick 4 and the Quick 4 Remixte?

The Remixte uses a step-through frame with a lower standover height. The standard Quick 4 has a conventional top tube. Components and wheels are otherwise similar.

Can I fit a rear rack and fenders?

Yes. The frame has rack, fender and kickstand mounts, so a rear rack and full fenders fit without adapters.

What size tires does it take?

It comes with 700c x 35c Schwalbe Spicer Plus tires. The frame and fork clear somewhat wider tires, but check clearance before fitting anything much larger.

Does it come with pedals?

Cannondale typically ships the Quick 4 with basic platform pedals. Confirm the spec with the store if pedals matter to you.

Is the Quick 4 Remixte worth it?

It is a light alloy step-through hybrid with practical mounts and clean cable routing. Weigh that against its rigid fork and rim brakes, and compare it with other alloy step-through hybrids before deciding.
