hello. i am newbie to power generation by bicycle. i have always shied away from the grunge aspects. nowadays, the hubs are higher output, less drag, and even have little plastic tubular capillaries {for technicians to microscopy out grease with nano snake threads- (somebody's gonna do it!)} so the dynohub can breathe; and will not seize. there is company making a battery to connect to the dynohub, to maintain the power output required to operate the Iphone. i see there is a Deluxe model that does not have the same output at slower speeds. I am basically ruling out bottle dynos for noise. i intend to stream XM/Sirius satellite radio into the iPhone as i ride. can no longer leave all my toys home. i ride what could favorably be described as a lope, unless going downhill. i will be riding moderately along , listening to satellite radio, streaming through my Iphone, while not draining its battery. what is wrong with me? which dyno do i need?
