Shimano Steps e8000 Torque/Power values

[EzRyder]

Does anyone know if there is information on how much Torque &/or Power is available in the different modes, Eco L/M/H, Trail L/M/H etc?

From the Shimano folks... here is a range table for various assist modes that you can extrapolate to power levels.

The chart should be updated to reflect that the max torque of STePS 6100 is actually 60 nm... the original STePS 6000 is 50Nm.

Hi there, This appears correct-ish. The max torque of STePS 6100 is actually 60 nm (see Shimano's website here: https://bike.shimano.com/en-EU/product/component/city---trekking-e-bike-e6100-series/DU-E6100.html). Also, the range on every STePS 6100 bike that I've plugged a 504 Wh battery into is 90-95 on high and 190-195 on eco (when one looks at the estimated range screen). And those are class 1 bikes, not EU bikes.

Thanks for the correction!

I found this chart online and it appears to be in error regarding the new Shimano Steps E-6100 system... the specs shown match the older E-6000 system.

Shimano has also introduced an entry level E-5000 system with 40 NM of torque.

I've ridden Steps 5000, and it's a lightweight and low-profile system that feels smooth and consistent so there's a lot to like about it. If you're mostly riding on flat ground, you'll probably like it. If you do a lot of hills, you might not find the 40Nm of torque to be sufficient. Going from STePS 5000 to STePS 6100 is a 50% increase in torque, but on a hill it will feel like an even bigger difference. You need a certain amount of torque to defy gravity, and the amount the torque exceeds that by is what you're perceiving. So let's say you need 30 Nm of torque to defy gravity on a steep hill, going from 40 to 60 Nm there might feel like you're tripling your power (one has 10 Nm of torque above the minimum amount required, the other has 30 Nm in excess of the minimum required to get up that hill).

Shimano's now slotting their motors into their traditional numbering system. So STePS 8000 is XT-grade, STePS 7000 is SLX-grade, STePS 6100 is Deore-grade, making STePS 5000 either what Shimano calls "non-series", or low-end Deore. Alivio is 4000-series, so if they do a STePS 4000 then it'll be an Alivio grade by Shimano's new numbering convention.

Thanks for the detailed information on the Shimano Steps system hierarchy.

Interestingly I have a few eBikes with the original Steps 6000 system (50Nm)... one has XT components and the other has SLX components.

First ride: Bianchi Manhattan

Every now and then you need to go to Italy and ride bikes in the sunshine. Or, at least, I do. This time I persuaded the nice folks at Bianchi to lend me their new Manhattan city e-bike for the week, and I'm glad I did: it's a very nicely-specced fast urban bike that's fun to ride and built to...

Does anyone know if there is information on how much Torque &/or Power is available in the different modes, Eco L/M/H, Trail L/M/H etc?

Specifically regarding STePS 7000 and STePS 8000, you can tweak how much power each mode gives you via an app. There are three settings for each. By default STePS 8000 has Eco set to high, Trail set to low, and Boost set to high.
