Transport Minister Norman Baker MP has announced that Southern Rail is to build an £850,000 "cycle hub" at Brighton station, with £550,000 of the funding coming from the Government.
The new two-storey building will be built at the rear of the station and have up to 500 spaces - increasing the total number of cycle spaces at the station by around 220.
Planned facilities include a cycle hire and repair shop, lockers, toilets and showers.
Mr Baker said: “We want to make cycling a genuine and viable option for everybody."
Work is due to begin in early summer and be completed by the end of the year.
