In order for an EEG signal to overcome noise it is typically time locked to an event and recorded multiple times. The signal is then averaged time locked to the stimuli. How is this done cycling around NYC? Do you politely ask a driver to swerve into your path 5 or 6 more times in order to get a proper sample of the event?
If you have experience in fMRI consider that this EEG is going to look like continual gradient and line noise artefacts, potentially highly correlated to the type of road surface the bike is currently on. Please explain how this can be 'averaged out' in order to obtain a signal.
