For me, its really having the bike at my friends house that is really killing things. It was fine for the first few years, but imagine everytime you want to ride, you have to drive 20mins, awkwardly try and find somewhere to park, deal with their new dog that has already tried to bite me once, move 4 damn E-bikes out of the way in his garage, then put them back and lock the garage, just to ride.
I've been ready to buy a house for months now, but frankly the prices are bullshit. If I could literally walk out my front door and get on the bike, then I would be way more inclined to ride.
In addition, I've expanded into new interests as well. So its still fun to ride, but just not the obsession it used to be.
