Cool new Triangle bag with carry strap

[mlt34]

I'm really on the fence about this new triangle bag. It looks like a good waterproof pack, and the main advantages are 1) it is easily removable and 2) it has a carry strap. This would be good for people who are in a similar situation like me: I've got a big heavy triangle battery that is awkward to remove and carry with me during times where I park and don't want to leave the battery with the bike. Generally I lock the zipper on my EM3EV bag but sometimes when I park in a less than great area I don't want to take the chance of someone simply cutting through my bag to steal my battery.

A bag like this would allow me to carry the entire bag with battery on my shoulder. And the button snaps make it easier to remove, with only one large velcro strap up top. I don't know, what do you guys think?

The downsides are it's a weird green and has a single zipper pull so I can't lock the zipper pull with a luggage lock like I do now...

They usually steal the whole Bike

I say buy one, and review it. Seems more water-proof than many existing triangle bags.

Does look good. I like the single big Velcro on the top, it should be quite strong.

Is it big enough? If so, as long as the big velcro strap holds securely and fits around top-tube it should work. But only you can determine if it’s worth it - ‘does look weird to my eye at 1st glance.

For small packs (5Ah hardcase) I'm kinda fond of those little top tube saddlebags. You can always add a couple for longer trips.

But another angle I’ve come up with for larger battery pack is using bag inside of a bag. In other words, battery pack goes into a normal tote bag with D rings for a shoulder strap. Next, stuff that into a EM3 triangle bag. Easy to take with me and looks “normal” which is always better for bypassing NYPD manned inspection tables in Subway stations.

That's actually something I've been kicking around for a while too! I'm thinking of sewing a 'skin tight' triangle shaped bag for my triangle pack that it always lives in, and it will have a small shoulder strap. That way when I take the battery out to charge, the bag is just a part of the battery and I never worry about it, but when I want to remove the battery and take it with me during instances I park for long periods of time, the battery's form fitting bag has it's own strap to carry it. Maybe eventually I'll get around to trying it....

The one thing issue I haven't quite solved is that I want the shoulder strap to always be there so it's ready when I need it (and I don't have to remember to bring a separate shoulder strap) but I want it kept out of the way 99% of the time. I was thinking maybe combining nylon webbing with a short piece of elastic waist band material sewed on the end that pulls the strap tight to the perimeter of the triangle when not in use, and stretches to allow a full shoulder strap when needed. I've have to keep kicking the design around a little more if I want to actually attempt to make the thing...

Most of us have numerous webbed bag straps with strong plastic clips and hardware laying around. I keep one inside the battery tote bag with the battery pack so it’s always there if/when I need it. I feel better with plastic hardware than metal when stored with the battery pack.

Recently, I bought and learned to use one of those sewing awls w/black thread. Very handy for adding D rings, repairing bags and/or modifying buckles and straps.

I wouldn't exactly describe these sewing awls as "speedy" but with practice and patience they can produce a nice stitch/seam.

Hey, I like it! Neat tool.

I actually got a sewing machine on aliexpress last year and it's been working great. I learned to sew and have made a number of projects, just haven't gotten around to trying my luck at a battery bag yet. That little tool would be a nice addition though. It's also probably great for heavyweight things like thick canvas or leather that a normal sewing machine couldn't do.

Yeah, nice bag but won't hold the capacity of an EM3ev bag. Perfect for a smaller battery though.

I don't need to carry my batteries that far, never park where there is much risk. But all my batteries get a coroplast box around them, that includes a carry handle. Then I don't drop em between the bike and the charge station.

Any regular sewing machine should easily make a carry bag, that could go inside any box or bag. Just needs room for the strap inside. or put d rings on the bag, and clip on the strap each carry.

I should get in the battery bag business. I have an industrial sewing machine. But no way anybody is paying me what custom work would cost them. No competing with china. It wouldn't fly.

We (dad, brother) learned automotive upholstery back in our show car day. Dad even machined a button covering die we crimped buttons using a drill press. Seemed you kinda need those commercial sewing machines when you get into heavyweight fabrics, piping, zippers, web strapping.

I agree a person can’t make much on single piece work. But if/when you “find” the ideal “design”, ring China for mass production. Of course, copies will soon flood the market, haha…

NYC ain’t got room for sewing machine these days. I’m just happy to be able to repair a favorite old bag, add D rings or rework a web strap with whatever hardware I desire.

Sewing awl can work through several layers of heavy materials. Slow but steady...

Purely FYI for ideas: I use a triangle frame bag, but inside that the battery lives in a smaller travel bag for carrying to/from the bike racks. So I never need to remove the triangle bag.
The smaller bag is designed to be thin, breathable, light, and is strong enough for a 11 lb triangle battery. Like this:
