From official data:

QUOTE Local variations in cycling rates at least once per week, for any
purpose, show large differences in cycling levels across England.

In 2022, Cambridge (50%), Oxford (35%), Isles of Scilly (30%), Hackney
(28%), and Southwark (25%) were the five authorities with the highest level
of cycling rates.

These rates show a large contrast to the authorities with the lowest level
of cycling rates, which were Bury, Sandwell (5%), Rochdale, Bolton (4%) and
Oldham (3%). This does not include local authorities where data has been
suppressed due to low sample sizes. ENDQUOTE

NOTE: the three authorities with the lowest rates of cycling, namely
Rochdale, Bolton, and Oldham, lie in the Greater Manchester area, which
consistently claims high usage for its bike-hire schemes. Clearly these are
not reaching the low-cycling areas, and Greater Manchester seems to be
doing little about it apart from talking-up its bike-hire successes.
