I think the original connection of Lonsdale for Mods was that when Carnaby Street first started getting noticed there was a Lonsdale shop right round the corner (Beak Street?), and since Mods were in some ways the instigators of wearing sportswear as casual clothing, they started adopting the T shirts, boxing boots, sweatshirts etc. Ditto for cycling. When I first visited Carnaby Street about 1980 (it was really crap then!) I'm pretty sure the shop was still there.
