Our E-bikes are built with one of three batteries that power the motor: the EnergyPak Smart, the EnergyPak Smart Compact, or the EnergyPak Side Release. Also available is the EnergyPak Plus, a small backup battery. All four rechargeable batteries detach from the frame and can be plugged in either on or off the bike, depending on how accessible your outlet is.
The strength of each battery is measured in watt hours (Wh)—a unit totally different from watts, which many cyclists use to measure their own power output at any given moment as they ride. But mainly: The higher the watt hour of your bike’s battery, the more power it can hold.
The EnergyPak Smart is the highest-capacity battery available for our E-bikes, ideal for long, intense rides where you’ll be using a large amount of pedal assistance or encountering a lot of loose gravel, snow, mud, or other unpaved terrain. The slim, streamlined battery is integrated right into the frame of the bike for a clean look and feel. It comes in three different watt hour (Wh) versions: 625, 500, and 400 (if the bike you buy comes with the 400 or 500 Wh battery, it’s compatible for an upgrade). All three Wh levels of the battery charge from dead to 80 percent in under three hours.
The EnergyPak Smart Compact is our 500 Wh electric road bike battery, which has the sleekest profile designed to help your E-bike blend in with a fleet of non-electric road bikes. Both the EnergyPak Smart and EnergyPak Smart Compact have aluminum casing to help prevent overheating, for both safety and battery-life extension purposes.
The EnergyPak Side Release comes on many of our commuter E-bikes and entry-level electric mountain bikes, shaped specifically to fit into step-through models. It’s available in 500 Wh and 400 Wh and slides into the side of the downtube, rather than removing from the bottom the previous two batteries listed. EnergyPak side release’s waterproof rating is IPX5, slightly less than the rest of Liv’s batteries (IPX6, which can withstand a bit more pressure).
If you’re taking an extra-long trip where you might need extra battery life before you reach a place you can recharge, the EnergyPak Plus, a 250 Wh backup battery, is available. It’s small, lightweight, and can be mounted directly to your downtube to add more miles to your ride. It charges relatively quickly, up to about 80 percent capacity in just two hours, so you can change up your main battery and this one in a single evening.
