I have a question, actually two questions, that I am hoping someone can answer. I purchased a Giant Road E+1 at the beginning of May. It has five levels of assist; ECO, ECO+, NORMAL, SPORT, SPORT+. The motor says " SyncDriveSport ." When I look on the Giant website SyncDrive Sport only shows 3 levels of assist. The only SyncDrive with 5 levels of assist is the SyncDrive Pro. Further, on the Yamaha website, there are only two motors that could have 5 levels of assist; the PW-X has 5 levels going up to 320% power but it only assists up to 25/kmh. There is also a PW 45 which does not have a description of levels but states that it is for bikes with assists upt to 45/kmh, and is the only motor model they show that assists above 25/kmh. Furthermore, neither the descriptions of motors on the Giant website nor on the Yamaha website show any motor with assistance levels with the names my bike has. On the Giant website the SyncDrive Pro shows a maximum assistance level of 360% power. Does anyone know what motor I have on my Giant Road E+1 and what is the maximum assistance level power % on my bike? Also, I see that Giant is no longer offering the Road E+1but now offers a Road E+ with a Syncdrive Sport motor and a Road E+Pro with a SyncDrive Pro motor. Does this mean that the current Road E+ that Giant is offering only has 3 assist levels as Giant describes on its website for the SynDrive Sport motor?

I think it's not necessarily simply up to the motor, but more up to the controller and firmware. I just got a 2019 Giant Fathom E+ and it also has the Sport motor. The controller and interface are called Ridecontrol One and it also has 5 levels of assist.
Older models had the three levels of assist, and newer ones have the five, even with the same model of bike. They updated the bikes, but not the info you are reading.
What year is the bike? I've seen different controllers and displays. Evo?

Hi,
Thanks for the reply. My Road E+1 is 2018. Do you know what the top level assist percentage is? Is it 320% which is the top level of the Yamaha PW-X motor according to the Giant website, or is it 360% which is the top level assist percentage of the Syncdrive Pro? Giant says on their website that the Syncdrive Pro is the same hardware as the PW-X but that they have been able to increase the percentages of the assists at all 5 levels with software. There is a comparison of in pdf file on the Giant ebike website.

My display is the EVO display.

I'm fairly sure that the Sport goes to 320%, and the Pro goes to 360%.

Thanks, I will try to investigate further and post whatever I find. There is definitely a discrepancy between what Giant says on its website (Syncdrive Sport has 3 assist levels) and what the Giant Road E+1 actually has (5 assist levels). Perhaps Giant will eventually rectify this.

I think Giant is better at building bikes than websites.:D
You can't find anything about the 2019 Fathom E+ I bought this week.

similar confusion i went through. my understanding is that from 2017 to 2018, Giant added 2 levels of assist. so they went through a mid-year model change but did not distinguish between 2017/2018. pw-x is 320%

I was been able to contact Giant by phone yesterday, twice. The person I last spoke with read the specifications to me for the Syncdrive Sport that is on the Giant Road E+1 which has 5 levels of assist. They are as follows;
80nm torque maximum at all levels of assist
110 rpm maximum cadence for all levels of assist.
power assist percentage increases;
ECO 50%
ECO+ 100%
NORMAL 175%
SPORT 250%
SPORT+ 350%

I was told that these numbers vary from what I might find on the Yamaha site because Giant modifies the motor performances through software.

The number I found was called customer support 866 458 2555. When I called the recorded voice said this was the recall number and to leave a message, which I did. My call was returned and the person I spoke with was very helpful, cooperative and knowledgeable.

These are not quite the same specifications as I was given on the phone earlier in the day when I called a different Giant number. This was the Giant general number which is 805 267 4600. I first spoke with an operator, asked if I could be connected with technical support and was transferred. The person I then spoke with gave me essentially the same information as above in terms of torque maximums, cadence maximums, and assist maximum of 350% (note the Syncdrive Pro used on the new Giant Eroad +Pro has a maximum assist percentage of 360% according to the Giant website). However, this person told me that the power assist percentages at the lower levels were the same as the Syncdrive Pro which would mean;
ECO 100%
ECO+ 175%
NORMAL 250%
SPORT 300%
SPORT+ 350%

The person I spoke with who gave me this information was also very cooperative and seemed to be knowledgeable. I don't think that he was reading the statistics to me as he did not give me specific percentages for the assist levels below SPORT+. He just said they were the same as for the Syncdrive Pro.

As I had left a voicemail message at the first number I had called, this call was returned later in the day. I told the person who returned the call that I had already spoken with someone at Giant who had given me the information I had requested but asked as long as he was on the line if he could confirm the information I had received earlier, which is the first set of assist level percentages I have listed above.

I did not ask either person if these specifications were the same for other Giant Ebike current models that use the Syncdrive Sport and have 5 levels of assist.

Yes it's true that Giant's Website is confusing. I guess ordering their bikes is like selecting from a box of chocolates. Well I pulled the trigger and ordered 2020 Explore E+ 4 STA (Medium). I think it's basically the 2019 model 3 updated with a 6 sensor Yamaha Sport mid-drive. I was checking the Giant Website the other night and it popped up cheaper than the 2019 E+ 3. No E+3 for 2020 so far. Ride, Forest, ride!
 
SM79, if you have a 2019, the Ride Control App (iphone/android) will let you adjust your settings at each level. For example at ECO the default is 50% and you can bump it up to 75%. The ECO+ is 100% and you can bump it up to 125% or 150%. Sport+ is set to the max 350% by default.
