It’s actually just a cheap Amazon net that I removed 4 of the clips from and zip-tied to the back of the basket (which is a Wald 137). I have no complaints, it’s worked for me. I went cheap because I wasn’t sure if I’d end up using a net or a bag, but I can recommend it.

I do it on my ebike sometimes. When I’m not using it to bike to the studio or to wherever I’m going that day, it can be a great excuse to get out and ride the bike and get paid for finding new little routes to get to different places around your city. And like I said, GET PAID FOR IT. Now idk what kind of ‘scooter’ you have so idk what the storage would be like, but I’ve got both a front and rear basket on my Lectric XP and sometimes I easily fill up both baskets. Thank god for my cargo net https://www.amazon.com/dp/B0022ZXO40/ref=cm_sw_r_cp_api_i_KVPC80MHGQZY2Q02CKRV

Not OP, but I got this net from amazon and have been very happy with it. (I had gotten a cheapie net for half the price before this one, but you can absolutely tell the difference.) https://www.amazon.com/gp/product/B0022ZXO40/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I got this one from Amazon. After a few big packages and probably improper wrapping (I’d wrap it around the seat when not in use in the future) it’s got slight stretch. Still useful whenever needed.

If you use a bungee net, there's no limit to what you can carry, provided it fits on the deck. Strap it down and just stand on the back of the deck, or ride with 1 foot. The net I linked could fit a week of groceries/case if beer/5 pizzas. Its just about balance

Something like this

They have a wide variety of sizes and are low profile so you might be able to just wrap it around the bag if you can't feel it when it's on your back then np, wrap the shoes up in it.

I have a porteur front rack (basically a little platform that mounts on my front wheel).

If I'll be on a particularly bumpy road, I'll use this: PowerTye 50152 Black 15"X15" Cargo Net featuring 6 Adjustable Hooks & Tight 2"x2" Mesh https://www.amazon.com/dp/B0022ZXO40/ref=cm_sw_r_cp_apa_basUBbAEW9B9T

Otherwise, if the road is smooth and the pack is pretty light, I'll just loop the Nomin straps around my handlebars so it rests on the platform lengthwise.

I just picked up this guy off Amazon. It was kind of an afterthought purchase, but I've ended up using it every day for commuting. It just hooks to the frame below the seat and works great.

I lost mine within the first month of getting my bike. Now I just opt for a cheap helmet net I got at the motorcycle store.

Cons: if someone wants to steal your helmet, it's really no hassle. Then again, if someone really wanted your helmet, a thin wire probably wouldn't stop them. My insurance against helmet theft is a cheap helmet no one wants to steal.

Pros: securely fastens helmet to bike, can throw a helmet under there while riding (couldn't do that with wire cable), can also use net for holding other stuff while riding, like groceries.

1 should be a cargo net or two... best bang-for-your-buck riding accessory ever. Some other ideas:

oxford heaterz heated grips (if cold weather is a factor when/where he rides)

TechSpec tank grips

colorful adjustable brake and clutch levers

rear stand (if his future bike doesnt have a centerstand this is great for maintenance

sena bluetooth headset

tail bag or tank bag (Kriega US20 is an awesome do-it-all tail bag option)

service manual for his future bike (if he's interested in twisting his own wrenches)

I've had very good luck with these bungie cargo nets, but I'm also attaching them to an actual luggage rack. I usually use two, one front to back, one side to side. https://www.amazon.com/gp/product/B0022ZXO40/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

The rokstraps work well too.

Maybe something like this

Put various size pillows between them and the net to keep their limbs seated in the slots.

Just a lame generic one I found on amazon. Does the trick though.

Here is what I'm using for the rack and for the cargo netting I'm using a cheap one on amazon. The rack has been great so far but I'm not 100 on the netting juuusssst yet

Fits my front rack perfectly!

This one is by far the best one Ive used. https://www.amazon.com/dp/B0022ZXO40/ref=cm_sw_r_apan_i_Z9S730KPK2558VNA1742?_encoding=UTF8&psc=1

Just some cheapo one off amazon. This is the one I got, but there were a million options that I'm sure would work just as well. https://www.amazon.com/dp/B0022ZXO40/ref=cm_sw_r_apan_glt_i_1JR1QJN3C2EFF1V3XNTB?_encoding=UTF8&psc=1

Just to throw out a slightly different idea, https://eugenebicyclist.com/2011/07/11/how-to-make-a-cratie-i-e-how-to-bungee-crate-to-bike/

You would not even need bungees then. Anything in the basket rides with you.

They also sell elastic cargo nets too https://www.amazon.com/PowerTye-50152-Black-featuring-Adjustable/dp/B0022ZXO40/ref=sr_1_5?ie=UTF8&qid=1479710141&sr=8-5&keywords=cargo+net
