ORTLIEB E-Trunk Rear Bag 10L Offering a spacious 10-litre capacity, the ORTLIEB E-Trunk Rear Bag is designed for electric bikes as well as non-electric bikes, and is super quick to install thanks to the Top-Lock adapter system. Disconnection is also fast, using the two release handles, so you can take the bag with you when you've locked up your bike. If you need to place the bag on the floor, the two attachment hooks act as feet, and there's a removable strap for easy carrying.  The E-Trunk is packed with features to improve functionality and the PVC-free PU-coated nylon construction ensures the contents is well protected from the rain. When in place, an anti-slip device prevents excess movement on the rack, and the bag is compatible with most carriers with an 80 to 160mm width. As well as the main compartment, there are three internal pockets, a mesh outer compartment and an elastic cord for stowing spare layers. You can even fit a bottle cage, dealing with the problem of not having enough mounting points on longer rides. Closure is via a secure magnetic lid, and the outer of the bag incorporates a place to clip on a rear light as well as reflective details to each side.
