I would have liked to see more rfoom in front of the cyclists rather than behind them. Good rule of thumb is to always shoot with more room for the person/animal etc. in front for them to move into
I think a bit faster shutter speed would be good here. Good expression on the subjects. Nice color. What would this image look like with the subject in the left third of the frame?
I find it awkard having them on the right hand side since they appear to ride off the edge. IMO it would be better to have them on the left side of the frame.
I think it'd be better to have the cyclists entering the photo (place tyhem on the left) rather than them leaving. Makes the photo feel cramped at the moment
