I had a harder time with this one. I think partly because it was inside at night so there was not adequate light. Hence the noise. This image was taken with an ISO of 1600, F3.3 and shutter speed 1/20. I found the faster the shutter speed, the better you could see the pedals, crank and spokes of the rear wheel while they were in motion. However most of the images with a faster shutter speed were too dark/underexposed.
