Cache Box for the Tern HSD

How to Install the Cache Box on an HSD E-Bike

The Cache Box is a discreet yet handy frame bag that’s made for carrying items you may need while out and about on your HSD e-cargo bike, such as a chain lock, hand pump, pocket tools, and more. Made of water-resistant material to keep its contents dry, the Cache Box bolts securely onto the bike frame under the seatstay, and holds up to 2 kg (4 lb) of your bike essentials. 

Although the Cache Box is designed for the HSD, the instructions for installing it on HSD Gen 2 bikes are slightly different from those for HSD Gen 1 bikes. But don’t worry—it’s just as simple! This article will provide all the necessary information you need for a smooth installation.

What's included in Cache Box

You’ll also need a few tools for installation. Grab a 4 mm Allen wrench (otherwise known as the L-shaped wrench) and a pair of scissors.

Not sure if you have an HSD Gen 1 or Gen 2? There's an easy way to spot all Gen 2 bikes, and that's the charging port located on the top tube. If there's no charging port on the top tube, you have a Gen 1 bike.
