Using the Basil Portland rear bike basket is a breeze. First, check if your bike has a MIK system carrier or carrier plate. If it does, you can directly use the pre - mounted MIK adapter plate on the basket to attach it to your carrier. If you need to adjust the strap, simply detach it and set it to your desired length, then click it back onto the basket's rim. When loading items, keep in mind the 10 - kilo weight limit and 25 - litre capacity to avoid overloading. For maintenance, regularly wipe the basket with a damp cloth to keep it clean. Avoid using abrasive cleaners that could scratch the aluminium surface. Store the basket in a dry place when not in use to prevent rust and damage.
