Combined with this one

the first one you atatch to a basket or crate of your choice. The second one to your rear rack. Then you click them together fo a ride.
Have not used this, just know how it works. Maybe there are something on youtube.
The caddy I use. We`ve got one on each Brompton (facing backwards becouse of the fold) to carry tiny backpack and another small bag that we use as handbag when riding. On the luggage block we have the heavyer Brompton luggage.
Also used the Caddy on my Daon Curve becouse I do not like the looong luggagetruss. I use this basket
https://www.sjscycles.co.uk/luggage/...grey-24-litre/ It connects to the Caddy at the top of the bag so hanging down from there. Caddy can not be mounted too low becouse of this. This is not my main bike or my shopping bike, I would go for something sturdyer for that.
The Dahon frontrack have been used on three bikes here, we have two now. None of them Dahon bikes but the rack is great if you like a pannier solution. Rides great also with just one pannier.
I like to be able to hang stuff on the bike, especially if on a bike holyday. If the bike is loaded down it is better to walk the bike home from the shop than to ride with plastic bags and stuff from the handlebar.
Edit: If you are close to a IKEA they have wooden boxes in two sizes that are cheap. Could maybe be combined with the two click fix thingys for the rear rack.
Maybe a Caddy and this one for the front?
