An ebike's battery life is influenced by several factors that can affect its maximum range. While our ebikes can achieve up to 60 miles of range under ideal riding conditions, range can vary from 20 - 60 miles based on many contributing factors.

Here's a list of the most common factors that affect range, as well as what you can do to maximize your riding time.

• Pedal Assist: Higher levels of pedal assist will allow for an easier ride, but will also draw more power from the battery. Lower pedal assist levels are better for getting as many miles as possible out of your battery.
  
  
• Average Cruising Speed: Riding slower will decrease the amount of energy you lose to wind resistance as the bike pushes you forward. Slower speeds will extend battery life.
  
  
• Tire Pressure: Keeping your tires inflated to the recommended pressure can help increase your range. Maintaining a proper tire pressure not only increases your range, but also helps prevent pinch flats! For most riding situations, checking your tire pressure at least once a week will keep your ride safe and energy-efficient.
  
  
• Load Weight: Carrying a heavier load can decrease your range. This includes the total load of both the weight of the rider and any cargo you may be carrying. More weight takes more time and energy to get up to speed, negatively affecting your range. It's best to keep loads light whenever possible if you're looking to extend your range.
  
  
• Terrain & Elevation: In general, riding over smooth and flat terrain will give you a longer range. Hills and rough terrain can greatly impact your maximum range, especially on higher assist levels.
  
  
• Wind: That's right! The wind can affect your battery range too! Riding into a headwind will decrease your range, but if you're able to catch a tailwind, you'll actually see that you'll gain more range! Be mindful of which way the wind is blowing when you are riding. If you've been riding in a tailwind, turning around will take more energy from the battery to get you home. 
  
  
• Ambient Temperature: Riding in cold weather will impact the battery's ability to function optimally. A good rule of thumb is, if you're comfortable, then the battery is comfortable too. This also goes for storing the battery too!
