Yes, you have to charge the battery if you want to use the electric motor, which we assume is the reason you’re looking into eBikes? The charge process is as simple as plugging it in, just as you would with your mobile phone. To fully charge the battery for either the Tern GSD, HSD or Quick Haul, takes about 4 hours.
The battery can be removed from the bike for charging. This is super convenient if you want to take it up to your office with you to charge while you stare out the window and think about what you want to do next with your Tern.
So how long does a charge last? Using a single standard, fully charged battery, the Tern GSD will run between 50 and 110 kilometers, depending on how heavily you rely on the pedal assist and how much load you carry. The Tern HSD will run for between 42 and 110 kilometers. The Tern Quick Haul will run between 53 and 105 kilometers.
