Loud Stereo for Bike

I had to take the fairing off the Type 10 to do it, but I've mounted a Ghetto Blaster on the forward cargo platform. I have two batteries, a 12V/12ah and a 12V7ah, and a 140 watt 115 volt inverter.


Photo was lit by the morning sun.


Plugged into the Battery charger.

Here's a bike I see around town all the time that has a car stereo and speakers installed on the front. Sounds pretty good too

A bike stereo is pretty easy to make. If you don't want anything that's too loud, the easiest way is to get some computer speakers that take 12v at Goodwill and power them with a UPS battery and get your music out of an iPod.

To get louder than that, the best way is to get some car stereo speakers (preferably more efficient ones! efficiency matters!) and make enclosures for them (styrofoam works well -- it's light, though it's not sturdy so you'll have to make it stronger somehow) and mount them somehow -- a trailer or Xtracycle works nicely. To power them, get an efficient T-amp (much better than a car stereo amp) and more UPS batteries or possibly LiPos if you have them available, and again, the music comes from an iPod.

True, but at least the guy in my video isn't playing rap songs that talk about drugs and violence. To me, that bike is a refreshing change from the usual bass-heavy cars I hear rumbling around here.

True that. My response is more tongue in cheek than serious. We've been literally silent for over 100 years, our time has come!

Yea, That guy has a cool bike. I like the fenders. Unfortunately, I'm logged in at a Library computer today, where I don't have the privelege of sound. The first twenty seconds of the video were best, where I could see the fiberglass job the guy did.
Thank you.

You're welcome I hope you can hear the sound sometime. It's pretty good.

Yes, I can hear the sound now. I think that the second song is Pink Floyd. I don't know what group played the first song, but if I was forced to guess, I would say it sounds like Frank Zappa's band.

But that is loud. My boom box can't go that loud.

That guy obviously built his own speaker enclosures as well as fenders. It also looks like the front of the bike is still in primer gray.

I'd love to see more bikes like this. There is a pedicab around here that runs around with a small boom box strapped to the frame. Here's a video I got of it.

You can beat that. Take the body off the Pedicab and set up a dance platform. Add a pole, pole-dancing young lady, and some disco music, and you're good to go...

This thread reminded me that I have a small set of powered speakers that I have always wanted to attach to a bike, but could never think of a way. Well, after adding some baskets to my mountain bike I realized I solved the attachment issue:
Its an "iPal", got it for Christmas or a b-day one year. Hooks up by cable to my mp3 player. Not as big or elaborate, but will help make the ride to and from work a little more interesting.

Not sure how well styrofoam enclosures would work (styrene maybe, but foam?) but PVC works.

Hello,

The stereo did it's job. I just got back from the Saint Patrick's Day Parade. I rode the bike ahead of the parade as soon as the road was closed. I chose to play the song "Pink Elephants on Parade" (from the Walt Disney movie "Dumbo"). I had to rewind ten times. Actually, it wasn't loud enough. And after I watched the parade, the battery was too weak to play, and the tape slowed down. I had the lights on, so I killed the battery.

If you can figure out some type of amplifier, the SanDisk Sansa Clip is a tiny mp3 player that has an FM tuner, voice recorder, and capability to record from the FM tuner. I have two of these that I use all the time on rides.

Seems to me you should be shopping around for a durable, lightweight solar panel for keeping your battery topped off.

That's a good idea. I had a 20 watt solar panel a long time ago, but I sold it to a friend who needed to keep his boat battery charged, in order to power his bilge pump. I really need to get a new 12v PV panel.

It's monaural, but here's another amplified bike I saw today. He wired a small mp3 player to an old Radio Shack megaphone. He also has some tiny powered speakers for when he doesn't need much volume.

I don't mean to get off topic, but I started this thread, and I thought it would be better to have one long thread, rather than two short threads, about the same bike.
Can you see what I did? Yes, the BMX bars have been replaced with ape-hangers (we called them hi-rise handlebars when we were kids).
Much more comfortable to ride. I don't have to bend over. I have actually used this bike to haul potatoes and onions home from the local vegetable market.

I have also made feet for the kickstand. Each leg of the centerstand kickstand has ten disks of yellow foam poster board, five drilled, three with cut slots, and two left whole to cover the holes, and epoxied together. Surprisingly , the foam board has held up to the weight of the bike. The feet were needed because the kickstand was a little too short for the bike. These feet also work to prevent to bike from sinking into soft ground. As you can see , I have a small piece of cabinet drawer plywood, under the kickstand, to protect the carpet.

These are the photos I took a few weeks ago and forgot to upload, Thanks for waiting patiently.
