Just starting out.
 

Can someone please point me in the right direction of what kind of bike to get, I'm recently starting to commute with my bike and it's really crappy so I'm looking to invest in a decent road bike to commute with.

Any bike will work fine for commuting, and older bikes can be fixed so they work like new pretty cheaply. However, if you have some money to spend on a road bike, I would recommend a 'gravel bike', 'cross bike', or 'endurance' road bike. These are all variations on the traditional road bike (the ones made strictly for racing), but are generally more comfortable to ride.

If you want more specific recommendations, post your budget and that will make things easier.

Without knowing your preferences, your commute, your location, it's pretty difficult to guess what kind of bike you'd want. What do you have now and what do you not like about it? What can you spend, are you shopping new or used? How long is the ride, and would you set out in rain or snow?

There are lots of variables.

• Are you commuting 1 mile on the flat, or 30 miles over wicked hills?
• Fair weather commuting? Foul weather commuting?
• Roads Conditions?
• Security/Theft at both ends of the commute?
• Budget?
• Goals beyond commute?
• Loads?

Personally, I like a nice road bike. But I also like Craigslist Specials where one can often get twice the bike for half the money. Thus, my choice would be based on what is available, not some pie in the sky ideal.

Some things to think about:
I like a steel frame because I find them comfortable, durable and affordable. Steel is a little heavier than aluminum, but often gives a more comfortable ride.
If you are commuting 5 miles each way or less and it's not too hilly, consider a single-speed bike. They are low maintenance, simple to operate and cheaper than a similar geared bike. Riding single-speed will make you a stronger rider and you may find it more fun than riding geared; I do and my commute is 25 hilly miles round trip.
Look for a bike that can use wider tires, 28-35 mm. They will help you negotiate badly maintained roads, dirt roads and other hazards and you'll ride more comfortably.
