Police are investigating the theft of three bikes from The Tri Store in Grove Road, Eastbourne, about 2.15am on Tuesday 3 September.
The suspects used a sledgehammer to smash their way into the premises and steal the bikes – one of which has since been recovered.
Officers arrived at the scene, and a man seen in possession of a brand new bike was spotted nearby and arrested in connection with the incident.
The other two bikes remain outstanding at this stage.
Police are appealing for anyone who saw what happened, or anyone with CCTV which may have captured the incident, to report it online or call 101, quoting serial 155 of 03/09.
Specifically, police are urging anyone who saw three men in dark clothing or anyone cycling in the area around that time, to come forward.
A 32-year-old man from Newhaven, arrested on suspicion of burglary, has been released under investigation pending further enquiries.
