To mount the Trixie bike trailer on a bike such as a Flyer, a few important factors must be taken into account:

- Design and type of bicycle: The trailer can usually be mounted on bicycles with a suitable rear axle.
- Permissible total weight of the bike: Make sure that the total weight of the bike and the trailer is within the permissible limits.
- Design of the dropouts or axle: The bike is usually mounted on the rear axle. An adapter may be necessary for certain axle types such as thru axles or solid axles.

It is advisable to consult the operating instructions for your bike model and, if necessary, contact the bike manufacturer to ensure that the trailer is compatible. Mounting on the rear axle is the most stable and does not hinder mounting and dismounting.
