Marylebone station has space for 462 bikes, while Euston can store 415.
The London terminal with the most space is Paddington with 682 places, while Waterloo has spaces for 573.
For those who get warm in the saddle, Paddington and Euston also have shower facilities.
All four are in the top 20 stations in Britain for storage, according to the survey by Leisure Lakes bike suppliers.
“Many stations are ‘cycle friendly’ with plenty of storage,” the company’s Ben Mercer said. “This makes cycling more accessible to commuters or students.”
Security is taken seriously with nearly all stations having CCTV in storage areas.
Most have sheltered storage for keeping bikes dry. But cyclists using Waterloo have to leave them in the open, exposed to the weather.
Simple bike stands and racks are the most common storage, while Didcot Parkway in Oxfordshire is the only one of the top 20 with ‘lockers’ as well as compounds, stands and racks.
