The pump and patch kit are effectively static weight on a bike. What's referred to as rotating mass on a bike (usually talking about wheels+tires) is noticeable. Maybe not as much on your city bike, but the thing that usually makes a bike feel heavy is the weight of the wheels, not the overall bike itself. Best of luck with them.
