Whoa, whoa, whoa, back up here. I'd be the last person to say that Lenin et al. didn't do their best to organize and lead the Petrograd masses but you're putting way too much emphasis on that. The bridge battles broke out without any pushing from the Bolsheviks at all. Hell, that evening, Lenin'd tried to get other members of Party leadership to mobilize what support they had to counterattack the Provisional Government after Kerensky shut down the presses, but he got shot down.
Honestly, with Kerensky threatening to call off the second All-Russia Soviet plenary session and breaking up Bolshevik printing presses, and considering the outbreaks of support the Bolsheviks and the rest of the far left got without even asking for it - July days ring a bell? "Take power, you SOB!" - saying that the October Revolution was totally top-down is absurd, a relic of partisan Western Cold War scholarship.
