The Trek MIK 2.0 Utility Trunk Bag is a versatile trunk bag built around the updated MIK 2.0 mounting system, designed to make on-bike storage as straightforward as possible. MIK 2.0 provides secure, integrated mounting to compatible racks with a click-on, click-off attachment that installs and removes in seconds without tools - making it practical to take the bag with you when locking up, transfer it between bikes that share a compatible rack, and switch between cycling and on-foot use within a single trip.
The adjustable carrying strap is a practical addition that the MIK 2.0 bag includes as standard - allowing the bag to be carried over the shoulder or by hand when off the bike. For commuters who ride to a destination and then carry the bag into an office, shop, or venue, the carrying strap converts the trunk bag from a dedicated rack bag to a functional carry bag without requiring a separate bag transfer. This dual-use character suits riders whose journeys involve both cycling and walking segments.
The MIK 2.0 Utility Trunk Bag is built around a practical multi-pocket storage system. An internal mesh pocket keeps smaller items organised inside the main compartment. Two side pockets - each with a smaller internal pocket - extend accessible storage to the bag's exterior for items that need to be reached quickly during or without opening the main compartment.
A dedicated zippered phone pocket with a soft lining is accessible from the top of the bag, protecting the phone screen from contact with other items and allowing access without unloading the main compartment. For riders using their phone for navigation or music, top-access phone storage is a practical convenience that the MIK 2.0 bag provides as a dedicated, separate compartment.
A light loop allows a rear light to be mounted directly to the bag, keeping it at a consistent height regardless of bag contents and removing the need for a separate seatpost or rack mount for the rear light.
The MIK 2.0 mounting system is the updated version of Bontrager and Trek's MIK rack interface standard, providing the same secure integrated connection to compatible MIK racks with any refinements that the 2.0 iteration introduces. MIK compatibility requires a compatible rack - confirm your rack uses the MIK standard before purchase, as the MIK system is specific to racks designed around that interface.
Reflective details are integrated into the bag's construction for enhanced visibility in lower light conditions, complementing the rear light that can be mounted via the light loop. An integrated rain cover is included and stored in the bag's rear pocket when not in use, ready to deploy when weather conditions change unexpectedly.
The bag is designed for compatible MIK racks using the MIK 2.0 mounting system. Confirm your rack uses the MIK standard before purchase - the MIK interface is specific to racks designed around that system and is not universally compatible with all rack types.
Yes. An adjustable carrying strap is included, allowing the bag to be carried over the shoulder or by hand when off the bike - a practical feature for commuters and riders who carry the bag into buildings or use it for both cycling and walking portions of a journey.
