Keep in mind that right now, all your bike memories involve him.
With the passage of time, you will be building NEW bike memories and experiences, and these will stand on their own.
Instead of your bikes just evoking sad old connections in your mind and heart, perhaps a positive step would be to start building up a few new bike memories to call your own.
New beginnings can start with just tiny little steps in a new direction. Make something small and good happen. Take yourself for a cappuchino on your bike.

I wish you well.
