more torque or newton inside 100 to 140 RPM.

Pity they haven't recorded the motor noise.

 

[Manu]

With more newton inside 100 to 150 RPM is more easy have 45km/h with unlocked speed

 

[Stefan Mikes]

Torque only means acceleration, not the speed.

The keyword in Manu's post is "unlocked." The PW-X2 motor is designed and delivered with a 25 km/h limit.

I understand that. With higher torque it is faster to reach the 45 km/h but it has nothing to do with maintaining the speed. To maintain the high speed, you need power. High torque is also helpful on off-road climbing; sometimes it means the rear wheel slipping (the mud, a wet stone slab...)

Will be interesting to see if Giant puts these in their bikes this fall. Wondering if Giant will stick with the 375 wh batteries or will move up in capacity. Most want more, though I'd have to admit that 320 wh in my Creo seems like it will be enough.

You're fit and able. Most of e-bike riders are not and depend on the battery very much. To be able to make a 100 km trip, I actually need more than 720 Wh.

I do get the sense I am a bit younger than most on here and that is a factor. But I also think that weight of the bike makes a bit of a difference. A more aero position on the bike makes a significant difference if you travel 30 km/hr. or faster.

I do recognize that some/many prefer a more upright riding position. One of my friends has back issues and insists on a completely upright riding position. In that case I suppose slowing down probably increases efficiency. My first ride on the Creo I used 2.2 watt hours per km, I was pleasantly surprised at that.

I've noticed many on here like to ride at speeds of over 30 and 40 km/hr. - I agree at those speeds you're burning through battery pretty quickly. On my Juiced CCS I can literally see the battery gauge dropping if I'm riding above 40 km/hr.

 

[Stefan Mikes]

You're right with the aero position @Captain Slow. This must bring a big saving at higher speeds. Next, if you are a lightweight person and your bike is lightweight too, you win on the climbs. I totally support the design of the Creo if it is used by the right cyclist for intended purpose. However, Giant downsized the batteries in e-bikes ridden for different purposes, that is, commuting and recreation.

Regarding the areo position, I often lean on the handlebars when fighting adverse wind. Cannot do too much until my stomach flattens when I lose weight

I say this because I see it from the point of unlocking, for yamaha so far it has never failed to have something illegal to unlock speed and I think this would not be the case in the future.

to have top speed you need revolutions and newtom, the newtom is the ability to move so much weight per meter, comparing to the FIRST MID-DRIVE PW and the new PWX-2 are too many differences, the first one DIES AT 100 RPM WITH 10 NEWTOMS COURSES AND THE PWX-2 AT 100 RPM GIVES ABOUT 70/80 NEWTOM = 70 KG IN ONE METER, WITH A WHEEL OF 29X2.0 PLATE OF 38 AND CASSETE 11 TO 96 RPM give 45KM / HY YOU HAVE 70/80 newtom, if you unlock

the pwx gives 45km / h with effort, the pwx-2 has much more potential and that will be noticed

Yes, that's a good point and the reason I was turned off on the new Giant ebikes i.e. only 375 watt hours of energy stored. I would agree for a commuter type bike that the 375 wh battery there is less adequate than the 320 wh I have in the Creo.

 

[Stefan Mikes]

I cannot fail to notice Manu you must have overslept your physics lessons...

RedPed module FW2.0 for Yamaha PW-X / PW-SE / display A & display C

The maximum speed of the RedPed module FW2.0 for Yamaha can be set via the app to an individual value between 15 and 75 km/h (the maximum speed actually achievable depends on the engine and the chain ring).

unlocked to Pwx-2

Yamaha pwx vs bosch a 45 km / h

you class physic lessons ,no par,newtom,no speed.

 

[Browneye]

50km/h??

 

[Ebiker33]

80nm max, they need to pump those numbers up, at least get up to the TQ motor at 120NM

 

[FlatSix911]

80nm max, they need to pump those numbers up, at least get up to the TQ motor at 120NM

Looks like the new PW-X2 motor delivers 70Nm at 100rpm and 60Nm at 120rpm...

 

[Stefan Mikes]

Brose motors deliver 90 Nm, so what?

I'm confused. My 2018 giant has 500 wh stored ( full e pro) and all but the cheapest giants still have that - am I missing something?

Will be interesting to see if Giant puts these in their bikes this fall.

They already have it in the 2020 range - they just didn't make much noise about making less noise
