Your Bike Has a Rack. Why Is Your Back Still Carrying Everything?

A backpack may be convenient off the bike, but during the ride, your shoulders and back carry every pound. Heat builds up. Straps restrict movement. And everything you need for the day stays attached to your body.

RideMate moves the load from your back to your bike—without leaving you with an awkward bag when the ride ends.

Drag

Pack it at home. Secure it to your rear rack. Ride through the city. Take it inside when you arrive. RideMate is designed to move with your day—not stay attached to the bike.

One Bag for the Whole Commute.

  • Pack Your Day
    Load the gear you need for work, exercise, errands, and the ride home.
  • Let the Bike Carry It
    Secure the bag to your rear rack and keep the weight off your shoulders.
  • Ride Through Changing Weather
    The roll-top closure and welded construction help protect your belongings from rain and road spray.
  • Carry On When You Arrive
    Remove the bag from the rack and use the adjustable shoulder strap away from the bike.

Use a properly sized protective sleeve when carrying a laptop. RideMate does not include a dedicated padded laptop compartment.

Pack the Workday, Not Your Back.

The 16L main compartment gives you flexible space for the things that change from one day to the next.

ROCKBROS 16L waterproof bike rear rack bag with roll-top design for cycling commuting and travel

A reinforced base helps the bag hold its shape on the rack, while six attachment points help reduce unwanted shifting during everyday rides.

Stable Where It Matters.

  • Reinforced Base
    Supports the load and helps the bag remain upright on the rear rack.
  • Six Attachment Points
    Distributes the hold across the rack instead of relying on a single strap.
  • Compressible Roll-Top
    Adjusts to changing loads and helps keep contents from moving inside the bag.

Built for Wet Commutes.

Rain can arrive before work, after work, or halfway between the two. RideMate combines TPU-coated 600D polyester, welded seams, and a roll-top closure to help keep everyday essentials protected without a separate rain cover.

Find the Right Carry Setup for Your Commute.

Every carrying system makes a different trade-off. RideMate is designed for riders who want to remove the backpack without committing to a bulky or proprietary rack-bag system.
Carry Option Advantages Limitations
Backpack Easy to carry anywhere after the ride Keeps weight on the rider and may cause back heat
Pannier Setup High capacity with a lower, more stable cargo position May provide more storage than everyday commuters need
Proprietary Quick-Release Trunk Bag Fast attachment and removal May require a compatible rack or dedicated adapter
RideMate 16L Balanced capacity, lightweight design, weather protection, and shoulder carry Fewer internal compartments and no one-click mounting system
