S/15 or XS/13,5'' WOMEN'S MB FRAME SUITABLE FOR DOWNTUBE MOUNTED BATTERY

[Grldn]

Dear all,

I am looking for a SMALL (S or XS- 15'') women's mountain bike frame suitable for BBS02 (bottom bracket 68-73mm) that has enough space to place a down tube mounted battery like the one in the following link:

I have already put the BBS02 on a Specialized Myka Sport Disc 2014 (S/15) with a VERY HEAVY rear rack mounted battery and this is not working. The bike is very heavy and unstable.Weight is not distributed equally.

Any advice/suggestion would be appreciated.

Thanks

Quick question: You don't want a triangle pack?

Thank you for your response, after long research and test drives i came up to the conclusion that this plastic cases are the most suitable and handy. The option of a triangle battery or generally a battery in a soft case is the last i would go for. What i want to do is to move the cells from the heavy aluminum case that is on the (extremely heavy) rear rack to a plastic case like this. I already use the BBS02 with this kind of down tube mounted battery on a man's Giant Trance size L and it works perfectly. The main objective is to find a suitable frame for this type and size of battery.

The bags are the last resort, and inexpensive. There are a lot of cases out there, water bottles and the newer slimmer cases. Someone like Paul, EM3ev, might be able to do something custom. If you want a new battery pack it all depends on the capacity versus discharge rate. You could get high capacity cells. less weight, smaller form factor.

I already have the battery cells, just need to take them out of the aluminum case and get rid of it and the rear rack. Then put them in a different case.
First and most preferred option is the case i mentioned above.
Second is the case you are talking about.
I am checking now the Specialized Expedition (http://www.eriksbikeshop.com/Assets/product_images/PR3C12498_mlg.jpg. )
The frame hopefully has enough space even on the S size. Looks like only this kind of ''hybrid'' and not pure mountain bike frames will work for this project.
If i can change fork/handlebars and put mechanical disc brakes it would work. I will check it at the shop tomorrow.
Thanks again
