This video gives a taste of the LiveOnBike performances we’ve been doing on SF Cruiser rides this summer. Joel Elrod, who had just finished playing a gig with Pleasuremaker, is drumming on a SPDS electronic drum machine. The signal from the SPDS is carried from the back of the Mundo to the front where it enters a DIT Head Unit containing a Rolls MX56c 4-Channel mixer and Shure Wireless body pack microphone, and DoubleWide Down Low Glow battery that powers the SPDS and a dual tube DLG system for 5 hours.

Skip ahead to 1:15.

The LiveOnBike rig also has a microphone seen in this video of Janaysa performing at the Bicycle Music Festival, but it takes longer to set up, so we haven’t been using it with Joel. The signal of the Shure body pack on the LiveOnBike rig is caught by the receiver on the backrest of the Choprical Fish. I select the tracks from an iPod on the control panel of the Fish. When I pick a new track, Joel listens for a few moments and then picks up the beat and improvises on the playing-card-sized rubber pads of the SPDS.

Both Adam (pilot of the LiveOnBike Mundo) and I have the ability raise and lower the volume level of the SPDS. When I was piloting the bike for Janaysa, I was able to set her vocals and keyboard levels independently using Channel 1 and Channel 2 of the MX56c. We were experiencing a very short range with our wireless transmitter that night, as you can hear in the first moments of the videos.

The DIT Head Unit uses the excellent 1-button KlickFix handlebar mounting system, and the wiring harness simply Velcros to the bike, so we can convert the Mundo from Town Hauler to Rock Star in only 5 minutes, and that includes mounting the SPDS and aTractor seat. I know that’s lot of names for you, but well, that’s how we did it.

A couple new products are helping bike people cruise with music this spring.

The Gadget Bottle is a functional water bottle that has no batteries or speakers, but its unique shape allows you to strap a cell phone with an internal speaker and listen to your MP3s as you ride. It fits inside a standard water bottle cage. At 2:35, inventor Steve Lach takes a phone call from his wife, holding the entire Gadget Bottle to his ear, with his flip phone securely rubber banded in place! No problem with one-handed use while cruising or training.

To up the volume a bit, the iHome2Go Cycler is a rechargeable black water-bottle shaped single-speaker music system that conceals an iPod and includes a handlebar mounted control.

Eugene, Oregon-based bicycle advocate and customer Shane Rhodes, a.k.a. The Bike Phantom, recommends it and says the volume is big enough for a small cluster of riders to hear the music. With a 3″ speaker, the Cycler isn’t going to deliver satisfying bass hits. It’s a basic law of speaker design that the smaller the speaker and its enclosure, the harder it is to get good bass response.

But how important is bass response on a bicycle? I think it’s essential, and Rock the Bike is obviously committed to the path of building bicycle music systems with cabinets large enough to deliver satisfying bass. With good bass, you and the people around you feel ‘in the music’. Without good bass, you can sing along with your friends to your favorite songs, which is a wonderful experience. But it’s a different experience than cruising in the music, which feels a bit like being in your own music video. Plenty of people disagree with me on the importance of bass response.

Others are more hardcore than I am:
