Jake's Bikes is situated in Haymarket Walk, a small shopping precinct between the Bus Station and St. James Barton roundabout (the Bearpit), almost underneath the Premier Inn hotel.
If you're walking or cycling, from the Bearpit just head towards the bus station through the pedestrian underpass and you will see Jake's Bikes at the far end of the ground floor of Haymarket Walk, opposite the Mayflower Chinese restaurant.
If you're driving, from the James Barton roundabout take the Marlborough Street exit towards the BRI Hospital, and then immediately turn left onto Cannon Street, just before the bus station. There is a pay-and-display car park on the right, or there is a loading bay at the far end of Cannon Street. Jake's Bikes is just down the steps on the left of Cannon Street.
