When it comes to the functionality of a bicycle trailer, there are differences that are considered when answering the question: what will I be using my bicycle trailer for?
There are 3 things to consider when choosing a bicycle trailer for your specific style of riding:
1. Is the bicycle trailer single or two wheel?
2. Does the trailer mount to the axle or the seat post?
3. What is the carrying capacity?
Bicycle trailer functionality differs by whether it is a single or two-wheeler, and how or where it is mounted to ones bicycle (axle or seat post). These two specifications will affect the cyclist’s ride, how much weight can be carried, where the bike trailer can be used (i.e.: paved roads, trails, city streets), whether it follows directly behind the bicycle and/or whether there is a possibility of it tipping over.
Axle-mounted single wheel trailers are designed to follow directly behind a bicycle’s back wheel, cutting a narrower profile through traffic and are as functional off road as they are in and out of city street potholes. Two wheel trailers differ in mobility and size. They do not follow directly in-line with a bicycle’s wheels, are much wider on the road and usually have a heavier carrying capacity.
Here is the breakdown:
| Attachment | Attachment | PROS | CONS |
| Single-Wheel Axle Mounting | Attaches from left and right side of axle | Follows directly behind bicycle wheels at all times | Heavy cargo is being balanced on one wheel and may affect cyclist |
| Single-Wheel Seat Post Mounting | Single bar attaching trailer to seat post | Less stress on axle or bike, quick and easy attachment, Most carry heavy loads | Does not follow directly behind bike wheels, heavy loads on single wheel trailer affect rider, most often does not have a flat bed area for cargo |
| Two-Wheel Axle Mounting | Attaches to left side of axle only | Allows you to place your bike down without affecting trailer and cargo, carry’s heavy loads | Wide and bulky, does not follow directly behind bicycle wheels (cautious wide turns needed) |
| Two-Wheel Seat Post Mounting | Single bar attaching trailer to seat post | Carry’s heavy loads, less stress on rear axle, seat post attachment can be used as handlebar | May tip on sharp turn or if you hit a pothole/speed bump in the road |
Whether you are commuting to work by bike or touring the country with a handful of things, bicycle trailers can prove to be a huge help in carrying heavy cargo.
