hello everyone.

i don't have any photos of my "street party bike" yet as it isn't working at the moment. my sony CD player's spindle is grinding the base so it's won't play anything. it's more of a cruising bike than a street party one. it's a mountain bike with a pair of mission M71s hanging off the rack in back in banjo saddlebags. as i already had most of the parts needed to throw it together, i decided to invest in a sonic impact class T amp to get rolling. i loved my panasonic class D reciever already, so getting a sonic impact was a no brainer.

the saddle bags are lined with a few layers of cut down 1/4" camping pad to keep the speakers from rattling in the cases. had i known back then i could just buy pannier hooks for about $2.50 a pair, i would have bought them instead of $80 worth of saddle bags. then, i could also unplug the ports for more bass as well as have a cleaner looking install.

on top of the rack sits a little dollar store basket that i put the amp in. i lined the underside with a piece of the camping mat to keep it from rattling too. it's held down by two bungee cords with pieces of velcro wrapped around them. i use the cords to suspend and shockproof the CD player. it works great. i've never had a dropout.

i came here though because i'm planning on hooking up the bike i edited in the photo i'm posting here. i like the idea of a trike because it's much more stable than trying to hook a mountain bike up. whenever i'm getting off my mountain bike, it tries to tip over or do wheelies with all the weight out back. not only that, 5 1/4" 2 ways with 10 watts can't compete with a nightclub's system blasting out open doors in a parking lot. the DJs here SUCK. i want to build a bike to "funk them up". everything they play is atonal and attitudal dreck.

i joined here so that i could post a thread to see if anyone knows where i could get 25wpc class D modules for my mains and a 50w monoblock for bass. i don't want to get too power hungry as i'm going to be using NiMH AAA and D cells. i don't want to lug a 40 pound car battery around in an approximately 20"w X 10"d X 12"h 3/4" MDF box with multiple drivers and probably some custom lighting too.

i can't create any threads yet, i guess because of posting probation, so i'll visit this thread. i'll be needing help from more tech saavy than me members to design the system. it will definately be acoustic suspension as i like tight punch bass and hate ported resonant boom. it gives me a headache.

i'm thinking of going with up to 4 X 8" daytons for bass duties as doubling drivers twice should give me 6 free dB, but wonder if that would actually be bad as they would roll off quicker. i know it takes internal volume to get extension. would a single larger driver actually dig deeper?

these are the kinds of questions i need to plan out the system. i DO have a pic that i photo edited of the bike i'm looking into. it's alot nicer looking than my 15 year old mountain bike.

some info i can share with everyone here is 1st check fossilfool.com out. it's a site dedicated to street party bikes and they sell some off the shelf gear too. as i started researching "bike stereos", i started finding sites like that one and this one too. there's another site that should be linked to fossilfool, or at least that FF is linked to. i can't remember what it's called though. it's related to FF. they want pics of bike systems, so definately stop there and show your stuff off. i was surprised to find there's actually a bicycle street party scene just last month.

as to batteries, energizer NiMHs are about the best you can get according to the shootout i linked to from steve's-digicams.com. photographer's are really into battery performance which helps us portable audio people out. good batteries are only part of the equation though. a good charger will get those last few millivolts out of a battery as well as not shorten it's lifespan like quick chargers do.

if you want to read up on batteries and chargers, check this link out. BTW, not all 2500MH (etc.) batteries are created equal. some manufacturers overrate their cells. anyways, here's the link and the pic of my next bike.

hmmm... i can't attach the trike pic because the file is too big. i'll have to see about reducing it as well as putting my current system back together and shooting it too

thanks a bunch for that handy 41KHz link v-bro! i've been looking all over for 25-50w class D modules to no avail. all i've ever found is 10-15w like one of the 41KHzs, sonic impact & charlize or 180w+ units like UCDs. at least now i know where to find units with more oomph than my sonic impact but that won't eat batteries like crazy

welll... there goes 16 minutes of my hour on this library computer! i was writing a reply regarding getting info, tang band drivers and my speaker project and got logged out when i tried to reply and couldn't retrieve the reply by backing up. hey... DIY, stop doing that!

i'll just say that i got parts express' latest flyer and tang band 3"" aluminum cone drivers are on sale for $8.88 compared to $17 something and leave it at that.

i won't get into using them in line arrays in lieu of lowthers again lest i waste the time it took to type this message too.

STOP LOGGING ME OUT!

it happened yesterday too. i had to rewrite the message at home and save it to CD to post it.
 
yes, i know how to do that, but of course the thought only ever occurs to me AFTER i lose a document unfortunately. i still do things like i'm at home out of instinct. oh well. if it had been anything SERIOUSLY important, i would have went over it again.

sadly, my current bike is STILL not working because sony is giving me the "your warranty is expired, it sucks to be you" repply about the CD player. the darn thing was acting up long before the warranty expired. i just thought it was CD-Rs causing the issue.

the problem is CLEARLY that it's defective. how could my listening to roughly 1 CD a week when i go get groceries or do laundry over 5 months cause a spindle to grind the base? my $10 durabrand unit took more abuse than that piece of junk sony and still works fine. it just doesn't have skip memory.

i'd been trying to contact sony literally for a coupole months, but i'd only remember the player at night when i'm grocery shopping or doing laundry usually. if i brought the info to the library, i'd forget it before leaving and i don't think this small town even has a repair shop.

i refuse to pay more than that piece of hfgouybu cost in repair when sony should be fixing it or replacing it to begin with.

i'm getting no-where with building a bike either as the uppity lowrider bike shops can't be bothered to answer the questions of someone about to plop $550 + shipping on a bike so to heck with them! i'm probably just going to get a "grandpaw" trike and hook that up. i won't deal with ANYONE that has lousy customer service.

anyways, here's another audio bike pic for now until i get something accomplished with my own projects. i'll probably just end up buying a panasonic player and giving evil sony bad PR every chance i get in the short term. it actually looks alot like what i was planning except i was going for a more low key/factory look

PS... it just got logged out AGAIN, but this time recovered my text by backing up and copying before logging back in. THAT'S where my replies are getting lost. after i logged in, i got a "no thread specified" error message
 
i beg to differ. if some big corporation sells me a DEFECTIVE piece of equipment that finally decides to totally break just AFTER the warranty expires and thumb their nose at me, i MUST get satisfation.

doing nothing and letting them get away with it is bad for one's health.

sorry, where i come from, there's consequences for wrongdoing.

besides, i'm quite convinced the piece of junk was DESIGNED to break asap anyways. their designers decided to put the battery compartment inside the player and all the way in the back where one has to put strain on the lid EVERY time one is removing batteries. one's knuckle will have to bend it back until one can get enough leverage to remove the battery. i cringed every time i had to remove a battery and feel the strain on the lid's plastic hinges.

i'm ALSO still holding a grudge from a sony technician DELIBERATELY breaking a cassette with test tones showing that my $700 portable cassette recorder (still under 5 year warranty) because i got sick and tired of sending it, waiting 2-3 months, getting it back unrepaired and repeating 3-4 times uuntil the warranty DID expire.

sony sucks rotten eggs. i bought a boombox from them (which sears lost, but made more than good on with store credit... great customer service sears!) that had an annoying mechanical buzz right out of the box.

oh no... sony has become a mortal enemy now with this latest nose thumbing incident. i will attack them every chance i get for all of the trouble they've caused me and believe it, they've hurt me more than i have them, but at least i'm doing SOMETHING.
 
here's some new pics

well, i bought a 24" trike yesterday and rode it about 10 minutes of the way home before i turned around and returned it. it was making me seasick. i just ordered a two wheeler and will be going the trailer route.

until then, here's some other systems

well, i got my street party bike back up and running. i had to buy a THIRD portable CD player to do it. the 1st one didn't have anti-skip and that wretched sony unit died right after the warranty expired. i had intened to buy a creative labs 1gb MP3 player, but the one i bought was SUPPOSED to work with windows 98 according to the box, but when i got it home, the software refused to load stating it wouldn't work with my OS and my PC couldn't recognize the player without drivers. needless to say those liars got a real nasty email from me. i'm still out $15 for the USELESS USB 2.0 PCI card i bought to be able to buy their bait and switch player. it drives me nuts when big corporations stick it to consumers and get away with it.

anyways, here's some shots of my bike with the new $20 coby anti-skip player i bought to get it back in action. it doesn't sound quite as good as the sony, but it works well enough and the volume potentiometer on the side makes reaching back and adjusting volume easy while riding. finding buttons is harder.

the bungee cords have velcro strips on them to hold the player and the extra springiness gives the player another layer of skip protection. i've never had a disc skip with this setup.

if you look closely, you can see a sonic impact amp at the bottom of the basket. it's only rated for 15wpc, but it can put out enough clean bass to humble most boomboxes except maybe that giant JVC 50wpc "kaboom box". the ports are plugged and the bass is tight and punchy if not quite gut massaging. people passing by at the nightclub are all surprised that a bike can play so loud and clean.

the speakers are mission M71s. (5 1/4" X 1") 2 ways rated at 88dB. they actually put out a surprising amount of bass for their size. with a 100wpc reciever, they can boom with some authority and stay clean.

the first pic in the album is my new bike and a photoedited concept for a wooden rack to hold the speakers and gear. the next 4 pics are the system as i'm using it now and the final pic is the concept i was originally going for with my system. i was going to build a subbed box for the back, but after riding a trike, it made me seasick so i scrapped that plan

http://s188.photobucket.com/albums/z157/zeroemission/

by the way, eventually, i plan on having custom fiberglass enclosures built for the lowrider with 92dB dayton aluminum cone 5" or 6" woofers with either a peerless 1" aluminum dome tweeter or maybe a planar or ribbon tweeter biamped with a second sonic impact amp. just the box will set me back $400+ though so that's probably a project for next year.

Agreed on the sony thing. They don't seem to be able to get optical drives right after all these years.

I had a similar experience with a CDR drive from them (back when they cost about $750)
It started having problems a couple months after I bought it. Tried phoning their tech support several times. Every time they suggested some other brand of media I should try. As it got older it got steadily worse. One friday afternoon I called them, they said there was a firmware update that "fixes that problem". When it didn't make any difference and I phoned them back on Monday they said my warranty had just run out, but that they could repair the drive for a flat rate of $300.

I bought a refurbished Mitsumi for $400 and have trashed sony at every opportunity since.

preach it brother preach it!

EVERYTHING i've ever bought from them has been a headache. my VCR's power button has fallen off so now i can't turn it on or off without the remote. the DVD player has THE WORST row after row of identically shapped buttons and refuses to zoom past 16X9 even when set up for a 4:3 TV set. my onkyo could turn 2.35 format into near full screen with minimal letterboxing where the sony cuts the top and bottom off when zoomed (just try to find the zoom button by feel!) and stays at 16X9. try changing a disc when the sony's playing... not gonna happen. try programming tracks on all 5 discs... not gonna happen either. then there's the boombox i bought last year that buzzed right out of the box, going in circles with their techs for a year on my $700 cassette deck until the warranty expired and they lost 3 case screws, or the mini recorder whose battery compartment was DESIGNED to break the second you try to change batteries. my CD player was designed like that too. sony likes to put batteries deep inside unfriendly cases that you have to strain and eventually break with every battery change.

the CD player is just the latest thing sony's done to *CENSORED MOST VIGEROUSLY* me over. enough is enough.

my philosophy is turning the other cheek is just asking for a second serving.

if i'd invested as much as you did on that disc drive, i'd be stark raving mad. did you ever try contacting the attorney general? they are good at making unethical companies behave. i had to use them when earthlink was DOUBLE BILLING me when my accessforfree (actually $10 a month account) expired and switched over to them. i only found out about it 8 months in when i tried to talk to a tech on the phone and they kept saying the email address i didn't know existed. then, once i found out, they just played the "it sucks to be you card".

when some big greedy evil corporation tries to stick it to you, write your attorney general. they're the next best thing to super heroes in fighting the forces of evil.
 
the sad thing though it's still just a millionth of a percent to them. it's like auto makers deciding how many lawsuits equals enough incentive to fix a problem.

still, if enough people that get shafted by any corporation speak up instead of taking what they're given like good little sheep, i mean consumers, companies might start to take notice.

it's all good, now i'm a big panasonic fan. so far, i haven't had any problems with anything i've bought by them. they, and samsung were the two most reliable brands in the survey i saw some 5 or so years ago.

JVC probably has to be the worst. i've heard alot of bad things about them and when i was TRYING to return a DVD box set that had terrible compression artifacts and dropouts to no avail at best buy, i saw a bunch of returned products including a camcorder and DVD player that were all JVC.

all of those brands USED TO BE bulletproof back in the 70s.

greed is a terrible thing. whatever happened to pride in craftsmanship?
 
WOW! what kind of amplification are you using? with that many speakers and that much cabinet volume, in bet you can really project.

a recumbent is nice for hauling all that weight in comfort.

man, i'd love to see that system smoke a typical car installation in a dB drag race. i bet you get alot of auto hate with that system.

it's too bad that there isn't a dedicated street party website where everyone can show off their systems and share tips and tricks. fossilfool is the closest thing, but they're about advertising THEIR systems more than showing everyone else's. i've tried to post there to no avail.

for the moment, i wouldn't be surprised that you have the loudest bike system in the world.

how about hooking it up visually now? put some EL wire or LEDs inside your bandpass boxes and maybe wrap some EL wire around the outside of your cabinets too, unless you're trying to be stealthy.

either way, nice system. very CLEAN looking installation.
 
Amplification on that version was one partly blown Class G custom amp (when it was working it was 3900w rms), the subs are taken care of by a JBL Class A/B 510w rms jobbie.

The priority with that system was to make it as cheaply as possible without sacrificing quality.

It went very very loud, and Critical Mass in London loves it. Always have people dancing along in the streets and never had a problem with a car drivers, they normally shout turn it up lol, even the police put in song requests. I guess what makes it different from most other systems on CM is that it's rich, full bodied full range high quality sound compared to most others which are distorted.

If it was in a car it'd go very loud and score some decent SPL in a db drag. Sadly, open air it won't rack up much.

As for finishing it (and this is the bit that I get called a chav), it has two 6ft EL Glow Wire around the subs on either side that dance to the beat. The sub enclosure has a 12" bi colour neon, and the top box has 2x 12" bi colour neons, 4x 4mm rear tail lights and best of all it's all remotely activated :)

You can see full specs on www.bikeology.net along with links to other systems and there's even a forum on there.

PS - As for being the loudest big mounted system in the world, I wish! That probably belongs to the AV2Hire guys from London (friends of mine) who have 3 radio linked bikes with proper PA cabs and a Bose Acoustic Wave Cannon.
 
cool, thanks for the info. it looks like you blokes across the pond really have your doo-doo wired tight. systems CAN move alot of air in the open. once someone with an SUV system played his bass so loud that he made all of the aluminum (translation: aluminium LOL) siding at a car wash buzz.

maybe SPL would be higher inside a car with the windows closed, but with as much power as you claim with unimpeded subs, your system would be quite competitive at sidewalk level.

out of curiosity, what is the purpose of the airspace between your subs & mains? do you have additional subs in there or is it a modular system for easier setup and takedown?

i'll have to check your link out. i'd like to see more as well as your friends' systems.

it must be nice living in a country that isn't as high strung as here. i get alot of "hatin' on my system" by local rednecks where i am, but the ladies love it. with just 10wpc & a pair of mission M71s i just can't compete with nightclub doors like you can so i have to ride the sidewalks. every once in a while a yokel gives me flack for it.

keep the bicycle faith my brother!

just getting back from your website, very nice with helpful tech data. the only complaint i'd have is that all of the links to high res pics are dead. i'd really like to look at that rig in detail. as much as i want to build an integrated bike system from scratch, i think it might be easier to do a wagon for my lowrider. i already have a 10" goldwood sub in a carpeted enclosure i could use for phase 1 of such a system and it would put my lowrider to good use. the only problem is i need to do something about the banana seat. 30 minutes riding makes my "fun zone" go numb, but the bike already gets thumbs ups for looks without a system.

BTW have you seen "choprical" yet? check this full custom out
