That looks like the original battery...  ???

How is that not leaking fluid everywhere?

If you click on the picture it blows it up some and you can see that the battery IS leaking . the original  battery box is total rust and you can see where it has rusted that whole area!!!! I could see mounting an AGM battery on it's side you can mount them upside with no problem. I guess he didn't care about acid running all over his bike!!!

Is there any tread on that tyre, what am I looking at?

My favorite is how the PO cut the seat pan to make room for the battery. Seems like a good way to potentially burn one's bum.

Lester, That looks like a different front guard(METAL) that has been completely rusted from the battery!!!!.

I'm sure it would amuse Nelson.  I think it proof that even insane people can be "creative".

You think sitting on the battery, insulated by a thin layer of foam, going over bumps and road grade changes is an improvement to the original design?

Is there ANY vibration isolation between frame and battery, as the original battery box has?

Did you know you can kill batteries or shorten their life with vibration?

Do you think raising the center of gravity on the bike helps it maneuver?

Is the bike marked up elsewhere with Crayon?

That's a good point.  When the rear suspension compresses, what does the tire now hit?

Perhaps the bike is just a display model, never intended to be functional?

considering the location of the battery and the impending leakage, i think it's appropriate to refer to the fluid as 'BATTERY ASSID"

Battery is a AGM Battery and is supported by insulation to prevent vibration. Looks like PO fabbed up a piece of sheet metal to hold the battery. Rear tire still looks new LOL. and acid isnt leaking, thank goodness.

 Reading various comments, I wondered what everyone was looking at?
It's pretty obvious to me it's a sealed AGM battery and you don't have front section of rear guard fitted

That is an interesting set-up to say the least. I can't believe the guy actually cut the seat pan and foam!

Would be fun to hear his explanation for that one.

What made us think it a lead-acid battery is because you see lead plates through the side, but must be an illusion!!

If you already have all the answers, why did you start the thread?

The sheet metal bracket is attached directly to the frame, and the battery is in direct contact with that.  Any frame vibration it transmitted directly to the battery.  Didn't you *just* have to replace that battery?
Come to think of it further, what holds the battery in place, the closed seat foam?

The setup is an engineering disaster, or afterthought at best.  I wouldn't consider living with it the way it is.  But then, I wouldn't have bought it with those mods, for fear that other things were tampered with in similar fashion.

Having said that, I'm a sucker for a cheap rescue project.  Were it free, I'd probably collect it to rescue and make whole again.

A switch to Lithium battery might be worth while. They are sealed like your AGM, but even smaller and lighter. It might allow you to fit a seat with a full pan.

if it's a sealed battery, i see no problems with it in that *location* on the bike.

but like the other guys said, how it is installed seems like a bad idea.  one short circuit and you're going to have molten foam all over your ass.  low risk of that really happening, but hey, being on fire sucks.

I think with some minor (or major i guess lol) improvements to the current mounting design you can have a safe and reliably mounted battery there.  I would fab a sheet metal insert to install on the seat pan to house/guard the  battery from being sat on, then mod the mounting bracket to be more vibration reducing.  but there's only so much vibration that can be reduced.  bumps are bumps, and people still drive hardtailed bikes without buying a new battery every 6 months.  i bet the sealed batteries hold up better against vibration anyways.

 Probably because it wasn't previous owner or wanted to get everyone else's opinion of just how dumb it is?

This is my first bike and dont know much about em so.....Bought the bike like this...Learning as i go. Thanks for your opinions and your smart a** comments. I recently did buy a battery but i killed the previous one by leaving kill switch on. Also its obvious i dont know all the answers or i wouldnt be posting questions on this wonderful/helpful site. I was just curious because ive never seen anyone else with this set up so thought i would ask. Im glad i did, so i can start looking into setting it up properly and safely. Thanks again guys

After 40 yrs of working on bikes I've seen so much stuff done I tend to be pretty cynical.
It wasn't you, but, I did get reaction and clarification  ;)
Did I mention I spend 4 yrs studying psychology?  ;D

I don't know how good it is bolted down but I don't like how close that positive side is to all the metal parts hard to tell from the pic.

You get used to it after awhile. Comes with the territory,I suppose. 


Welcome to bikes! Have fun with it! I know you will.

I would think it's pretty hard on the ass to sit on that for very long.. Is there some reason the battery CAN'T be mounted in the box meant for it??? Maybe the PO bought too large of battery!!!

 Crazypj! Did you just STUDY PSYCHOLOGY or did you learn PSYCHOLOGY???  That's why DOCTORS always just PRACTICE in medicine or in their speciality because they never actually LEARN it!!
Did I mention I SPENT over years 40 years working on aircraft and I only had to PRACTICE for 2 years!!!

I just read that AGM Batteries are vibration resistant.........Bike didnt come with original battery carrier so thats outa the question unless i buy one. What would you guys suggest? Should i buy an even smaller mor expensive battery or should i attempt to get a cafe racer seat so i can store battery in hump. I like the original seat for passengers once the bike is safe. Ive been riding the bike here and there, even a couple of times to work and all seemed fine. Should i stop riding it?
