Beginner friendly: Moderate

Starting a bike renting side hustle can be relatively easy for beginners with no special skills or background. Setting up a bike rental business typically involves acquiring bikes, safety equipment, and creating rental agreements. Costs range from $500 to $2000 depending on the number of bikes purchased. Online resources like YouTube provide tutorials on setting up and marketing a bike rental business, making it easier to learn the ropes. With effective marketing strategies and good locations for bike stations, beginners can start earning a profit within 2-4 weeks. I'd rate it a 3 because while it requires some initial investment and effort to set up, the learning curve is manageable for most people.
