How about two brompton folding pedals, hinging on the ends of the back wheel axle, with skate wheels on end, running on ground so taking most stress off bike. Or even 2x of those folding scooters, minus the handlebars, 1 each side, hinging down like running boards, off the axle ends or rack.

Or just bungee a folding push scooter onto the rack and tow passenger on scooter, using bungee as tow rope! :-D

That's probably legal too, since a solo motorbike can legally tow another solo motorbike.

Great, probably better towing with that trailer hitch idea that bolts a pieces of pipe with flattened & drilled ends onto the bike and scooter, with a piece of fibre-reinforced rubber hose jubilee clipped between them. Just flex enuff, while not letting scooter hit him in the a.. when he brakes!

No fixing, the approved and often used methods employ a rope held in place by hand or foot grip. I've used the hand method, towed bike with the rope around the headstock and then to the handgrip where the hand grips it. Slightest sign of a problem and the grip is released allowing the rope to slip off.

 

I don't like the footrest method, too tiring.

I think I've decided, I'm going to use the bike seat:

I'll use it on my Dahon Jetstream:

 

It's a bit expensive at 190USD shipped + custom taxe... but it has also a big luggage space (199 mm (7.8 in) wide, 284 mm (11.2 in) long, 72 mm (2.8 in) deep) so I'd be able to put my battery pack inside.

 

It would be a very uneven bike with a BPM of 4.3kg on the rear and 5kg battery pack + 2kg luggage... but I hope it will still be manageable.

I don't think it'll fit the Dahon because of the rear suspension. Don't forget that the wheel goes up and down,so you can't fix it to the wheel and the frame.

I was thinking the same thing but apparently the rear tube allows a bit of wobbling:

Still not convinced?

Should work with some seasickness pills for the pillion rider.

That adjustment is just to get it level, then you lock it in place, so no movement. All the force of the suspension would go through that tie-bar, which would break it or your frame before you could carry your passenger as far as the nearest pub. If you can imagine it, you've got two people on a frame, which has a hinge between them, and they're kept apart by that adjuster rod. Each time you go over a bump, there will be a massive force on that rod, which will rip it straight off.

The seller told me it has been tested on 4000lbs before it breaks and until now it was working on all suspension bikes.

 

He said it should be fine on my bike. And I'm also thinking to loosen the nut so it would allow to wobble

I'm very surprised that the Seller said it was working on all suspension bikes.

 

That type of fitting is only suitable for Hardtail bikes.

 

As the owner of a xtra-cycle cargo bike, I quite like the idea but can't see how it could possibly fit a rear suspension bike.

I'll stick my neck out and say that it can't work on a suspension bike.

 

Also, if you were able to leave it loose, the seat would rattle backwards and forwards making it very uncomfortable for your passenger if they could stay on.

I'm quoting the seller

"We've had a bike seat on a full suspension bicycle and it worked great. As long as you are riding on flat roads, there isn't any issue at all. The passenger on the bike seat won't get the benefit of the suspension, but the cushion is well-padded and it's still a comfortable ride."

"Our bike seat frames have been load tested and it took well over 4,000 lbs before the tube-steel-alloy started to bend, so I don't think there's much to worry there."

"although the Companion Bike Seat attaches to the seat post with a "hinged" turn-buckle, so it will provide a little movement for the suspension"

Well, it sounds like there is only one way to find out ... and that's to get a willing and game 'companion' to try it out. Knee and elbow pads at the ready ....

Well it would work on a flat road as the suspension isn't doing anything then. On a bumpy road it will be interesting to see what breaks first ~ it is a rigid structure, you are locking up the suspension.

You won't be able to get passenger insurance cover cwah, so you must warn any passenger that they are carried at their own risk. Use a printed slip handed to them for this to help prove you warned them, since the consequences of an accident could bankrupt you.

I finally purchased it for 190USD....

 

Hope I won't have problems with customs.

 

Will arrive next month... I'll keep everyone in touch and I plan to install it to my dahon jetstream

The seller is an idiot.

This could prove Wheelie exciting
