I will have to take my recumbent trike to the public weightbridge to find out!
It is made of lead rain gutters reinforced with concrete. ......
actually it is about 17kg excluding rack and mud guards and my overfilled panniers!
With panniers it weighs about the same as a small house - especially going up hills. Maybe I should revise what I carry - but I know that the day I set off without 3 spare inner tubes and a repair kit, or the spare 8 links of chain, or the first aid kit including an adult and a child size airway, or the large adjustable spanner, or the spare set of spare lights (in case my spare set doesn't work) or the multi tool, or the spare battery for my phone (even though my phone will run fine for a day or two even with sat nav running) or the spare.........well you get the jist.
