The bar indicators on Bosch Intuvia

[JackStraw]

Hi All,
I hope you are well. Do you know what is the exact meaning / definition of these bars on Bosch Intuvia display?
I know this is to do with how much assistance you get from the electric engine at a given moment but is there any unit of measurement behind it?
ECO - 40% of assistance
TOUR - 100%
SPORT - 180%
TURBO - 270%

Thanks

I have only ridden Bosch a few times but isn't it measured in Watts? That was certainly the impression I got from the line graph shaped like a o_

I have a Raleigh Motus Active Line with Bosch Intuvia.

In general terms the % assistance is a % of the total assist available. So Eco offers 40% of the assistance available, Turbo offers 270% of the assistance available. But the amount of actual power delivered depends on the motor and the battery. Your bike should have a manual which will tell you the figures and this site (I'm sure Bosch has one as well but I couldn't find it just now) explains in more detail https://www.freeborn.co.uk/help/bosch-assistance-modes-explained.

It can get quite complicated at first as depending on the system it's possible to customize the assistance given, either through the app or the device. Bug enerally I've found but generally I found when first using the bike that experimenting with all modes was best.

I can't customize my levels but I found as a guide Eco I use all the time, and when loaded with panniers or trailer is fine on flats or gentle hills. Tour I used more on steeper ascents, or when loaded on most surfaces (I've used a trailer with my bike hauling 30kg or more - very useful!). Sport I've rarely used but Turbo I have for very steep ascents or when starting off with a very heavy load.

I'm sure this really does make sense, but I can't figure it out. How can it offer more than what is available?

Turbo offers you a ton of assistance, but when you select it, it says "sorry, that's not available"? Kind of "jam tomorrow" sort of thing?

That web site is interesting

It explains why Turbo (that I hardly ever use) sometimes feels like it is helping a lot - and sometime doesn't

I think it’s like in Spinal Tap

If I understand the tech correctly then the motor is capable of providing a higher assistance for a short time, so that's why you get the +100% modes. Or the Spinal Tap explanation is equally as important.

My assist can be weird under weight, especiallu when towing I noticed I need to pedal at consistent cadence, or the assist seems to come in waves. Certainly when I was towing some bricks, at least 35kg a time worth, it worked best in a very low gear spinning quite high.

 

[ebikeerwidnes]

I do find that highish cadence is best on mine

powering up a hill standing on teh pedals and turning them slowly doesn;t get you the assistance you expect
change down and you get more

or so it seems - by that time I am too k******d to think properly!

Does yours not whine at you to change down? The last one I rode kept telling me to. Even when assistance was off!

No - very basic version though
2019 version - Purion controller and active line motor

never makes any kind of noise or suggests anything

Mine does, I think I can turn that 'feature' off though.

What model motor and controller?

What model motor and controller?

It's Active Line and Intuvia, the manual says I can turn it on off: https://cdn.css-help-center.prod.co...255_Intuvia_MY26_WEU_oReg_v1.pdf?_=1749727465

If I remember after my ride tomorrow I'll try it.
