If you'd like to ride a bike, but just can't bear the thought of giving up your 10,000 watts and and 18-inch subs ... your Fitty Cent or Solja Boy (or whatever... sorry, I'm not very 'hep' to that type music) ... this might be just the ticket.
You're neighbors can still know you're headed their way, five minutes before you get there! (I imagine it must have a bank of batteries, and you can plug it in and recharge it.)
Seriously... can you imagine punks rolling down the Greenbelt on a nice summer day with these things in tow? Surely Picnic Rage would ensue.
