Nothing with cycling on the road but there are strict traffic laws which governed how cyclist should cycle including the maximum no. cyclists in a group etc. in
groups of no more than five bicycles in length.
" On roads with two or more lanes, cyclists are allowed to cycle two abreast, capping such a group to 10 riders. On single-lane roads and in bus lanes during bus lane operating hours, cyclists would have to continue riding in single file, which caps such a group at five riders.
This is due to “space constraints” on Singapore's urban road network, the Ministry of Transport had said then.
Those found violating the rule would face a fine of S$150. "
