Folding Bikes - bringing your girlfriend her bike?

I am sure I saw it somewhere here, but am going to ask you all, anyway.
at certain times, I must meet my wife, and then go home together.
since I don't own a car, I was thinking of carrying a folder with me on a folder,
then cycle home together.
should I
-carry it on a trailer?
-design a backpack, to carry a 16" folder.

a backpack would be nice, since my hasa folder is approx. 11kg..

any ideas are welcome..

I vote for trailer or figure out a way to put it on the rear rack. Carrying it on your back would be very uncomfortable.

Do you have a rack? I would see if I could strap it onto my rack in an upright position.

I vote trailer, no doubt. I would hate riding if I had a 25-30 lbs on my back.

For short distances of under 2 miles I have been known to just ride my bike and "tow" a second bike alongside using my right hand on the stem of the bike being "towed". This is not the safest way and I would only do this for short distances on a relatively flat route, and I keep my speed very low, around 7 or 8 MPH. Braking is reduced as you only have one hand free for the brakes, plus you have the added weight of the towed bike. This should only be done if you are comfortable with your skills.

For anything longer than a couple of miles, if you don't have the skills, or on very steep hills I would suggest using a trailer. Using a trailer is much safer all the way around.

chop did a post on it seacrh for him

Depends on the bike.

If you're both on folders, then a trailer would be great.
If you're on a cargobike or extracycle however...

when you have a sewing machine and an old back pack, you can make a back pack specificly to carry a folding bike. you can sew some longer straps to the bag and then fasten the bike to you back. just like bike meseenger do carry huge boxes with them... other then straps, velcro bands and elastic cords can be used as well.

This is how I usually carry two folders:

now i see your moulton again....any updates ???

Easy, make a little wooden tray with one of those Motorcycle tanknets/nets used on some bike baskets and if possible make the wooden
tray easy to remove from your rear rack. This would set you back about $ 25 and would be a heck of a lot less top heavy/uncomfortable
than the backpack option.

Everything is stripped off and clean, but sitting in the garage. I'm still saving up for the new and replacement parts. I already have a vision of what it' gonna be though: all flowery and girly, like the London Cyclechic R20:D
