Not too sure how to approach this - Don't have anyone to ask

Hey everyone haven't been active on here just because of all the drama hope everyone has calmed down now.

I want to just say this to somebody but I don't really have anyone to ask so I thought I'd make a post on here.

I've always loved motorbikes and as I'm getting older I find myself wanting one more and more, but the issue is my entire family are so anti motorbike it's ridiculous. I've tried to bring it up in the past in a jokey kind of way but they all just say the same thing "if you get one of those death traps I will smash it up myself" blah blah blah.

I'm still living at home I have a car but it's quite expensive and now that I'm not doing 140 mile journeys all the time since I split with my ex the cost of the car is getting kind of unnecessary and I would rather not pay for it. I could do my CBT and get all the tests done and I'll be able to get a nice bike that won't cost me £340 a month like how my car is currently.

I just don't know how to bring this up with my mum mainly because it will just turn into an argument and all she'll go on about is the fact that my step dad had a friend that died on a bike a couple years ago. But if I say yeah well I wont ride like a d!ick like he did, (because that's what got him killed he was doing motorway speeds in urban area and broadsided a car).

It's also a bit deeper than the fact I "just want a bike" I have lived my life trying to do the things that I think everyone will approve of and not always doing what I want to do. And seeing bikes just seems so freeing a stress relieving being in the open air like that.
