Modular backend system.
You can couple on a bicycle, for example, a load hanger, a child trailer, a dog trailer, etc. This is comparable to a vehicle with 4 wheels with the appropriate weight of a trike or quad.
To couple on a trike or quad an additional trailer is not so useful, much better seems to use the already existing three or four wheels direct for more transportation.
A few examples of the idea of the modular backend system:
a) Short version without rear module:
The frame was briefly provided with a separation point behind the rear axle, where other rear frame parts can be easily screwed on. Nevertheless, there is usually enough space around the driver's seat to invite something.

b) Camping module:
The camping module is screwed on to the separation point. If the tailgate is open, there is a small camping table. The load capacity of the trike has grown by more than 100 l and that with an additional weight of about 3 kg.
In the camping module fits in, for example, a whole shopping from the supermarket, or even tent, swimwear, gas cooker and food.

c) Tub module:
The tub of a wheelbarrow with a capacity of about 85 l was installed in a module, empty weight approx. 6 kg. If bulk material is in, the tub can be easily dumped. Up to 25 kg can be transported in this way.
