There’s the obvious ones, like Condor, Cycle Surgery Spitalfields, erm…
All much of a muchness. Loads of Evans. All are staffed by underpaid bods with varying degrees of interest. Stocked with loads of gear at full RRP.
It’s a bike shop, what do you expect? I can’t imagine any bike shop is ‘not to be missed’.
Brick Lane Cycles is a nichetastic fixie/fakenger shop. Lots of decent second hand bits, mostly roadie, but some nice bargains to be found, if you look closely. It’s not actually on Brick Lane, but on Bethnal Green Road, at the top end of Brick Lane.
