There are dedicated cycle stores throughout the residences - ask at Customer Services for the nearest one to your building. Depending on where you live, there are different ways to access them:
Apartments (e.g. Kinder, Allen Court)
Get your key fob activated at Customer Services.
All other properties (e.g. Stephenson, Broad Lane Court)
Pick up a cycle store key or get your swipe card activated at Customer Services.
Cycles should not be stored in your accommodation as they can obstruct fire escape routes. If found, they'll be removed and you'll have to pay a £25 retrieval fee.
