DIY portable, adjustable and easy to build MTB kicker ramp

Borrowing from various DIY guides on Youtube and the internet my son and I built our own version in a day - copying the best features from the ones we found. We wanted something that was easy to built, could be put together quickly, reasonably light-weight and with adjustable run-in plate and angle on the kicker. Result was better than expected and takes only a minute to assemble. Dimensions 150 cm x 65 cm and adjustable height 50 cm or 56 cm (only 6 cm - but a lot more kick :-) ).

Dimensions of the individual parts can be found on these photos:
