Fly loads with bike. Takes ten mins to shove it in Evoc. Don’t let anything down no need. I recommend air in your tyres, will protect the rim. Reverb I just shove down. Planes are completely pressurised.
At check in you check in both hold and bike bags. Then take bike bag to oversize check in. Collect everything other end. Sometimes oversize stuff ends up on separate area.
You have bought sports bag for cycle extra baggage allowance (some are free on long haul but limited to 23kg) and it’s within the weight limit.. Easyjet weight limit is 32kg.
The overall strategy I adopt is to fit in with the airlines sausage system. If you do you go through no issues.
