Battery range

What is the battery range of a SHIMANO STEPS e-bike?

There are many variables that determine the range of your battery. These can include rider weight, wind, terrain type, and assist level being used.


Long-term battery storage?

  • Store in a cool, indoor location with a stable temperature between approximately 10 to 20°C
  • No direct exposure to sunlight or rain
  • Charge battery to around 70% before storing
  • Every six months, charge the battery back up to around 70% 
  • Before using the battery again, charge it completely

What do I do if the range shown on my bike is fewer? 

The range overview is recalculated continuously by calculating speed, driver behavior and power consumption. This means that range overview makes a prediction, which can vary depending on these different factors.

Battery capacity

What is the battery capacity?
SHIMANO STEPS offers two battery options: 418 Wh and 504 Wh

How much does the remaining battery capacity decrease after several years?

Generally, the battery will decrease by approximately 5% a year. Which means about 95% capacity remains after year one, and 90% after year 2. 

Charging battery

Do I need to empty the battery completely before recharging to expand battery life?
No, as this will not affect battery life. Simply charge your battery any time you feel you need it.

How long does it take to charge a SHIMANO STEPS battery?

The battery will charge from 0-80% in 2 hours, and from 0-100% in 4 hours.

Running on empty battery

My STEPS battery is empty. Do I need to charge it right away?
You need to charge it back up to 70% if you plan to directly store your bike for six months or more. Otherwise, if you plan to use your bike in the very near future, simply charge the battery before your next ride.

Can I still pedal if the battery is empty?
Yes, but you won’t have any support. As e-bikes are heavier than normal bikes, it’s best to avoid these situations. If you are using Di2, you can still shift gears for a while as this uses less energy.

Will display still work if battery is empty?
Yes. When riding with an empty battery, the ride-assist will stop but there will always be some extra ‘bring me home’ energy to run the display as well as (if installed) bike lights and Di2 shifting. 

Does pedaling recharge the battery?
No. Pedaling the bike does not recharge the battery.
