Giant Ease e is very less supporting

[Hampie1965]

I have recently bought a very nice Giant Ease e , ( bike has 2 batteries, 36V vertical positioned) but very less supporting, do somebody have experience with such kind of problem?

 

[Jeremy McCreary]

very less supporting

Not sure what you mean by that. Are you getting less assist than you expected? Are the battery mounts not secure?

 

[Stefan Mikes]

I know what he means. The Ease E+ provides a little assistance.
Well, this is a relatively old e-bike, and the front hub motor is really weak (30 Nm). It is what it is.

Thanks for the reply. The assistance is only when I push hard on the pedals.

We don't know what the history of the e-bike is and what could be broken (if anything).

 

[Jeremy McCreary]

Does this occur in the highest assist level? With maximum throttle? Does the bike have torque-sensing assist?

could be 2 things, Sensor calibration or batteries are end off life. You could visit a proper bikeshop (from the top of my head, Theo Schilder would be the one).

buiten dat, heb je een Charge of een Evo display op de fiets? Beiden hebben een optie om foutcodes uit te lezen, en is dit een versie met voorwiel motor of een driveunit in het midden bij de pedalen? Ik zou verwachten een met een voorwiel motor.

 

[Stefan Mikes]

With maximum throttle?

What throttle (Wrong continent!)

Does the bike have torque-sensing assist?

PAS only.

 

[Jeremy McCreary]

PAS only.

Torque-sensing is a type of PAS. So is Specialized's power-sensing assist.

 

[Stefan Mikes]

Torque-sensing is a type of PAS.

I said that in the sense of the "American PAS", that is, the system only checks if you are rotating the cranks and the wheel's moving.

So is Specialized's power-sensing assist.

You have just coined a new and proper term. Our mid-drive systems is a way more refined.

We need a term to arch over cadence-, torque-, and power-sensing assist schemes. And we have one: pedal assist system (PAS). Why muddy it up?

Just one reason to keep PAS generic: My wife's Velotric has a dual PAS — cadence-sensing and torque-sensing, either/or, switchable on the fly.

You have just coined a new and proper term. Our mid-drive systems is a way more refined.

Just a logical extension of the cadence-sensing and torque-sensing terminology, as the Specialized mid-drive PAS doles out motor power primarily on directly measured rider power.

 

[Stefan Mikes]

Jeremy, anyone here understands PAS as the system that just activates the motor by pushing pedals. Why to create confusion.

Exactly — why create create confusion?

And what makes that narrow usage (to mean just cadence-sensing PAS) American? You're using it, and you're Polish. Some of our UK members do it, too. And I'm American, and I don't.

 

[Stefan Mikes]

Simple PAS has overwhelmed North America with thousands of cheap Chinese e-bikes that either have "PAS" or "torque sensing" and/or "throttle". (Throttle is illegal in the EU and UK).

Europe has heavily gone towards mid-drive since simple "PAS" was a thing.

What's "simple PAS"? Why not just say "cadence-sensing" so everybody knows exactly what you mean?

The simple PAS does not measure cadence It is on/off.

This bike is build in Flevoland NLD, this bike has either a fron wheel motor and a torque sensor attachet to the BB, the one with the midmotor Dive Unit has a DU from Yamaha branded for Giant. Both these systems use a toqrque sensor and a speed sensor, the Yamaha DU also has the driveshaft sensor like the Brose, Mahle, Bosch etc DU's

Based on the discription by the OP from Alkmaar (which is a city in Noord-Hollad NLD) has one presumably based on the discription from a batch prior to 2020. The ones with the frontwheel motor can actually be callibrated by a Giant dealer (for the BB torque sensor) and they can run a diagnostic for the battery health. One thing I forgot in this case (few years have passed since last servicing a Giant from this series) is that the speedsensor could also be dropping signal. Based on the OP I do think its ither the torquesensor calibration or worn batteries, so a dealer should be able to check those out.


btw, the assembly line n Flevoland builds a lot of (E-)bikes for a lot a different brands (had some though talks with dealers where a different brand came out of a bike box than what was written on the outside) and yes also the big names from the USA are also assembeld there.

Really sounds like a local Giant dealer is the OP's next step. Hope there's a quick and inexpensive fix.
