Until 1 July 2013, the only bicycles that were allowed were folding ones. DLR stated that this is because if evacuation is required, they would slow down the process. DLR cars, especially older rolling stock, were not designed with bicycles in mind – if they were allowed, they might obstruct doors and emergency exits. Since January 2014 full-size bicycles have been allowed on DLR trains at off-peak hours and weekends (except Bank Station, where bicycles are not permitted for safety reasons).
