OYBike was a bicycle sharing scheme in west London, Reading, Farnborough and Cardiff in the United Kingdom.

The Cardiff scheme ended 23 December 2011 with OYBike citing a lack of ongoing sponsorship.

The OYBike system was developed by former cabbie Bernie Hanning over the last 20 years but officially launched as a trial in 2004.
