Specialized Rockhoppers/Hardrocks, and some awful ‘Smith & Wesson’ things.
City of London Bicycle Babylon used to ride stuff like SC Chameleons and Spesh S-Works HTs, but they ran up a £17000 debt with the bike shop I worked in so their account got stopped until they paid up. I think most of the money they spent was an utter waste though really; just a bunch of coppers wanting nice bikes, rather than simply tools for the job.
I think far more coppers should be out on bikes; the number of overweight plod is increasing dramatically. Have they dropped the fitness requirements or something? Too much driving about in cars eating bagels, and not enough chasing villains. Lazy buggers…
