Shimano currently offers 3 different battery capacities: 418Wh, 504Wh and 630Wh. They all produce the same amount of power. However, they differ in the amount of charge they’ll hold. Think of it like the size of a gas tank. Therefore larger battery choices won’t help you ride faster or climb better, just ride further & longer. For example, assuming your motor is consuming 250 Watts of power a 500Wh battery’s charge would last two hours. Although the larger the batteries capacity, the heavier they are.

General Battery Information

Can I upgrade battery from 418Wh to 504Wh?

Yes, you can.

Can I upgrade battery from 418Wh or 504Wh to a 630Wh?

It depends. Not without a BM-E8016 battery mount. If your trike was purchased before 2020, then you’ll certainly need to upgrade the battery mount. Trikes purchased in 2021 or later generally have the new mount, but check to be certain. The 630Wh mount is backward compatible with the smaller size batteries, but not vice versa.

Can I lock the battery?

The battery locks into the mount automatically. There is a key included which you can use to unlock and remove the battery.

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, motor choice, rider weight, wind, terrain type, riding speed, and assist level being used.

Long-term Battery Storage

  • Store in a cool, indoor location with a stable temperature between approximately 50 to 70°F with no direct exposure to sunlight or rain.
  • Charge battery to around 70% before storing
  • Do not keep the charger plugged in for extended periods (i.e. weeks or months)
  • 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 less than I saw before?

The range overview is recalculated continuously by monitoring speed, rider behavior and power consumption. This means that range overview makes a conservative prediction, which can vary widely depending on these different factors, even between rides. A hard fast ride uphill on a previous ride will cause the estimate to predict less range for the next ride. It’s only guessing.

Battery Capacity

What is the battery capacity?

SHIMANO STEPS offers three battery options: 418Wh, 504Wh and 630Wh.The 630Wh is not directly interchangeable with the others, as it requires a heavier duty mount.

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

Will emptying the battery completely before recharging expand battery life?

No, 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, depending on the size of your charger. Chargers are available in 2 Amp (typical) or 4 Amp (large) sizes.

Running on an Empty Battery

My STEPS battery is empty. Do I need to charge it right away?

Depends. If you plan to directly store your bike for six months or more, you will need to charge the battery back up to 70%. Otherwise, if you plan to use your bike in the very near future, simply charge the battery before your next ride. It is not required that you fully charge the battery before using it.

Can I still pedal if the battery is empty?

Yes, but you won’t have any motor assistance. 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 the shifter uses far less energy than the motor.

Will the display continue to work if the battery is empty?

Yes, when riding with an empty battery, the ride-assist will stop but there will always be some residual battery power to run the display, as well as integrated bike lights and/or Di2 shifting (if installed).

Does pedaling or braking recharge the battery?

No, the Shimano STEPS Systems do not support regenerative braking, therefore pedaling or braking down hill does not recharge the battery.
