Having analyzed specifications for 4 Tern models, we've found that their stock tires typically favor efficiency and comfort.
Most Tern riders we see are under-inflating their tires, which significantly reduces battery range. Our data suggests that for pavement riding, maintaining pressure near the upper 20% of the manufacturer's recommended range provides the best balance of speed and range for these bikes.
Pro Tip: Check your tire pressure weekly. Tern e-bikes are often heavier than standard bikes, making them more susceptible to pinch flats if pressure drops too low.
