Just curious how old are you?
In my personal experience my pops got me into bikes, all kinds. In high school I restored his 70's road bike and I still have it to this day. It's the last thing I have of his and I'm really glad my pops got me into bikes. However my brother is the exact opposite doesn't like bikes or anything my pops and I did.
I would be straight up and I bet your pops would understand too.
