It's a bit more complicated than that...
Experiences vary. I've been riding across zone 1 for 18 years in rush hour without a major incident, and with only two very minor ones. In all that time I've never seen an incident. For more on the risks of riding in London, google "Jo Wood denominator neglect".
Bikes on trains and some tubes are basically allowed outside of rush hour. The most popular bike in London is the Brompton, precisely because it's not subject to this restriction.
