My BMC road machine 01 51cm fit without removing the front wheel
During summer time I keep my bike at all time in my car at work because I go for a bike ride when I finish.
The front disk wheel is a thruaxle I have to unscrew with Allen keys and not a quickrelease
I slide it rear wheel first and then my 40cm width handlebar with the front wheel goes in the trunk by entering at 90 degrees to clear the lower trunk plastic part then I turn it and slide it with the whole bike and it goes in in barely 5 seconds.
My wife can’t do it and can’t get the bike out as it’s a specific twist to get it in and out
