    Hi,

    I'm looking to build a bicycle soundsystem (well I've already build two, but one weighs a ton and the other is too quiet and has fairly poor sound quality)

    Priority is the efficient and light speakers that give a decent enough quality sound. The setup is battery powered and will generally be playing in the open air both on the road and at festivals, there will usually be multiple bikes synced together if that makes any difference.

    I've found there is a decent selection of 12V amps available thanks to car based systems, but I don't know enough about speaker specifications to know what I'm buying. Any recommendations?

    Thanks,
    Michael

    Probably a bit obvious but...

    Choose high efficiency speaker drive units. Typically PA drivers have a higher efficiency than traditional hifi drive units. Horn loaded high frequency drive units can be extremely efficient.

    Select drive units that use neodymium magnets as they're usually much lighter (often pricier though).

    Class-D amps (some of which are misleadingly called class-T amps) would be very efficient and make the most of limited battery power. Even low powered 'Class-T' amps will give high volume when coupled with a high efficiency speaker.

    You could consider an active speaker design which would do away with typically heavy passive speaker crossovers but the weight saving could be negated by the need for additional amplifiers. Active designs typically have marginally superior efficiency and audio quality but not sure if it's worth the extra expense for a bicycle setup.

    Suggest these type of speaker drive units:

    Just an example - other manufacturers sell similar ranges.

    Could always adapt an existing high efficiency passive speaker kit:

    Lots of other possibilities on this website.

    There are lot of battery powered Bluetooth speakers that can easily be held in one hand. Given the application, these seem like the simplest solution, though they are small and you can expect performance in proportion to their size.

    Samsung Bluetooth Speaker Dock - Google Search

    Beats Pill 2.0 Speaker - portable

    Superfi - HMDX Jam Party Bluetooth Wireless Speaker

    Superfi - HMDX Jam Rewind Bluetooth Wireless Pocket Speaker

    Superfi - Jawbone Mini Jambox Wireless Bluetooth Speaker (Opened Box, Blue Diamond)

    There are tiny amps that can be battery powered that sound pretty good, though the rated power is low -

    Lepai for example -

    Lepai amp - Google Search

    As far as speaker, you have to accept that the sound is going to be limited by the size. How big can you handle? How small do they have to be?

    You might be able to find some tiny satellite speakers, though don't expect any bass from them -

    Superfi - Wharfedale Modus Cube Speakers (Pair)

    W x H x D (mm): 142 x 160 x 122

    In all honesty, I don't think you have remotely given us enough information to advise you in any productive way.

    How big can this system be? You plan to carry a 12v battery, some type of amp, and some speakers of unknown size. That doesn't seem like it would lend itself well to easy casual riding.

    We need to find some compromise between what you expect, and what is reasonably possible.
