Best road bike for beginner

Hello everyone,

I'm looking to buy my first road bike. I've decided to go with a used one, my budget is 400 USD. I'm 5'1", so it's been hard to find a bike for my size. I've found four good options and would like know your opinion. Thanks!

1. Triumph IronHorse Sport – 200 USD

2. Dolce Specialized Road Bike – 300 USD

3. Felt ZW95 – 400 USD

4. Specialized Roubaix – 400 USD
