Bike Desk Business Expense?

Last year I purchase a road bike for $5,000, a stationary trainer and desk so I can ride and work at same time. 

The bike is stored in my home office full time and I work for 2 hours a day, five days a week while riding. I take it out a few times a month on weekends. 

 

Would the bike, desk and stationary trainer count as office furniture and qualify as business expenses? 

 

Background:

I am fully self employed and qualify for the home office expense. I typically don't have a ton of business expenses.
