Pannier for rear-battery bike

[Sfield]

Yesterday was my first day commuting with my Raleigh Detour IE-- and the ride went well. What didn't go so well was getting my Blackburn Rear Central pannier bag to stay on the rack (this fit my regular bike, but that never did end up getting used to commute). So two questions: first, is it incompatible with my e-bike or am I doing something wrong, and second, any recommendations for a pannier(s) for a laptop on one side, and when needed, to pack clothes/ groceries/ battery, etc on the other

Pictures of your particular issue may illuminate? -probably a mod or adjustment to increase the strength of any elasticated clamps or clips will be all thats needed. tho the variety of options and solutions makes it tricky to know them all.

Due to a rigid frame and bumpy roads when needed my laptop is carried in a backpack on the bike, when just a laptop and a handful of peripherals like the power brick its not a great hinderance and the added security of constant personal contact and not double taking over every 2nd bump in the rd outweighs any other issues for me


my paniers are the cheapest from ali express but can hold 2x 8xtin 'hic' packs each side without splitting packs (can take a bit of persuading with tall tins..) zips? ha, no they didnt last long.. and as such i have no qualms leaving them attached permanently to the bike.

And while not stylish at all i like the convenience of largeish boxes front and rear to just drop bags etc in when needed.. but the cheap n tatty look i aim for to hide my bike when left in town might not be what your after..

I've posted a pic before but here it is again. I put one of my batteries (14s6p) in my trunk bag leaving the panniers open for everything else. The battery is strapped to the rack through tiny slits in the trunk bag and panniers using very large cable/zip ties. No issues after 8,000 miles.

(So is a "trunk" bag called a "boot" bag in Euro land? - heh!)

You already have a sizable battery on the down tube, why do you need a second battery?

I had aliexpress permanently mounted strapped on panniers (one on each side). Didn't like it because it is permanent. I like quick release systems such as Rhinowalk & Ortlieb where you lift a strap and the pannier releases instantly from the rack.

I don't like range anxiety and rarely charge to 100% in an effort to prolong the lifespan. My rides are typically 40-60 miles with an occasional 80+ mile ride. Some of my best rides started out as a 20 mile jaunt and turned into an epic 75 mile trip. The 14s4p shown in the picture on the downtube (was my original pack) was not enough and when I needed it most (I'm an old guy) it would die. It's been replaced by a 14s5p since the picture so I run 14s11p total of Panasonic 3400 mah cells. Most of the time I charge to 80% and still don't have to worry about a 60 mile ride.

Hmmm.... I never thought about or needed panniers to be removable. Even when I travel overnight I roll my bike into the room with me. It's even been on a few hotel elevators - chuckles......

For my use (grocery for example), it's nice to be able to lift one strap and take the whole bag into the house instead of unloading each item into another bag.

Ok, so you need the range. I had a 48V 7 Ah 5 lb battery for a short while strapped on the rear rack and could feel it negatively affecting the handling, until I relocated it to the down tube, which made it so much better.

How about this for your bike? Ebike Triangle Battery | EM3ev

Dude - I go riding with those panniers full, stuff piled and strapped on the trunk bag and many times add my handlebar front bag full. So what handling? I'm a country cruiser. I'm more worried about a comfortable seat after 60 miles then I am handling - heh! No need to point me towards other batteries when I have no problems. I'm very happy with what I have.

OK I get the full picture now . Enjoy your ride!

Many rear racks for touring have a bar for hanging the panniers a couple inches below the rack top. One of those would more than likely address your problem nicely.

That looks like a nice well made rack. How much is it? Link?

It's only one that I found on an image search. There are many others like it. This one comes from Great Britain I think:

I found an odd assortment of hardware helpful for creating tie-down points for bungee cords:
Amazon.com Black Button Stud Screws
Amazon.com Gun Black Chicago Screws
Amazon.com Metal Belt Clips Single Hole

Note that I also make my own bungee straps using 3/16 inch diameter shrink wrap and JB-Weld to join the ends together forming loops of the appropriate length.
Amazon.com Bungee Cord 1/8 inch diameter

Do you have pics of where you installed these hardware assortment? Is 1/8" bungee what you use mostly? Is it strong enough for most uses?

 

[LewTwo]

Well this is the only current example I have. It is mainly for small item so I do not have to carry them in my hand or a back pack (those are hot when the temps hit 100 degrees in the shade). The bit on top is one of the bungee straps. The four bolts that mount the battery plate are about an inch too long (on purpose). That is what holds the bungees on the underside. The belt clip is in on the surface on the the front of the box. Note the reflector on the ass end. I also used the Chicago Screws to fix it in place so that the inside surfaces of the box are relatively smooth.

I wore out the wheels on Burly Travoy trailer (too many trips to the grocery store I guess). I did something very similar with the bags on it but I actually used paracord to secure the bags.

Ok I see you made the bungee into a loop doubling it's strength so essentially you have an 8 mm bungee. Do you JB Weld the ends with a butt joint? I assume you do not melt the ends with heat before the epoxy? How well does it hold? Any failure?

Affirmative on the butt joint. Never assume ... I melt the ends and then trim them square with scissors. I also use the 5 minute version of of JB-Weld and let it set (as opposed to full cure) before sliding the heat shrink over it. It helps to have something to hold the ends together while the epoxy is setting (two alligator clips fixed 1 inch apart).

Strength is based on area. I could do the math but I am too lazy. I would hazard a guess to it being a closer equivalent to a 6 mm diameter bungee than 8 mm. Negatory on the breaks thus far (knock on wood).

Went to Maldives with my girlfriend, Came back some days back. You all are great folks, Thanks for the head-ups. issue sorted.

Many thanks.
