Two Month Review Of Cervelo Rouvida Rival Road Ebike

[Stefan Mikes]

@rdv please be aware major industry players such as TREK have left the Fazua system for good because of the system unreliability. The manufacturers' new choice has been the TQ system...

Another member recently reported an 80-90W Pr cap for medical reasons.

With the average Pr a way below that! One of my e-bikes of choice has been a Vado SL Gen 1 with a 35 Nm motor. I just ride it slower than my 85 Nm Vado 6.0 allows for.

A measured average rider's power from one of my recent rides. It could even be as low as 47 W (I suffer from leg atherosclerosis).

Wondering if this thread might awaken.

I've started contemplating a switch from a TQ HPRR50 to the Fazua Ride 60. It's my particular age (upper70s) and health (angina) that are not allowing me to draw the TQs full potential. I can't contribute more than 100W for more than a few seconds, or the angina will shut me down entirely. That becomes an issue with the TQ due to its 200% maximum support, which means I only draw a sustainable 200W from the motor, missing out on the 300W stronger riders can take advantage of. (I've pleaded with TQ to allow a 300% maximum assist, without increasing its 300W output, to no avail).

An associated issue is that I generally pedal at relatively low cadences of 50-70 rpm, mostly around 60, which is not best suited to the TQ.

The Fazua Ride 60 seems to overcome these constraints if I understand its operating parameters correctly. I'd appreciate feedback from users of the Ride 60 on whether a setup such as I might start out with is tenable at 60 rpm.
Breeze: 100W input, 100 or 125W maximum support
River: 100W input, 200 or 250W maximum support
Rocket: 100W input, 350W maximum support, possible short boost to 450W

Dreaming?
Thanks, Rob

Hi ,I ride on the Rouvida Cervelo with Fazua Ride 60 for about 9000-10000km/y [5500-6000 ml] mainly on mountain and steep climb over 10%...I'm 72 ,178 cm x 78kg, in 2020 I got 2 stents and due to a cancer I had radioterapie twice...Nevertheless for the time being I'm still in a decent shape [ I never smoke,no alcohol, drogs,mainly vegetarian...]
My set-up on the assistance are:
Breeze 100w/130w [ used at 90%]
River. 180w/170w [ used at 10%]
Rocket 280w/150w [ never used]
On uphill [ gradient from 5% to 10%]in Breeze mode my average HR are between 120-130bpm and HR max limited to 150bpm...
The assistance is consistent and fluid but as for all mid-drive motor linked to the speed cadence : my average is between 60rpm to 75rpm
Honestly speaking I do not believe You could feel a huge difference with TQ50
but I cannot report about the Fazua performance at its max assistance
For what's concern the reliability the only issue I encountered was about engine noise under stress...I got two engines replaced on full warranty without any problem [ all the matter solved in two days]
If I can express my suggestion most probably You could get a better solution with the new Bosch SX but I had not opportunity to test so far comment based only of expert reviews. Good luck and enjoy your ride

Pinarello dropped the Ride60 in their Nytro road/gravel e-bike line due to unreliability and lack of manufacturer support. They switched to TQ. There are still lots of them out there, though.

What kind of bike do you have now, and if you could have everything, what would it be? We only know what motor you have.

As reported in my previous message the Fazua's assistance has been efficient and extremely fast and this is not only my experience but from other friends of mine.The system is extremely flexible and tunable ,the level of assistance not invasive but concrete...The main issues recorded with the Ride60 have been at the beginning linked to some software bugs, now fully solved via OTA update,and the mentioned noise under stress...Personally I had two engines replaced under Warranty more or less after 5000/6000km/each .
For what's my knowledge, as few friends own Trek with Tq50, some have experienced the same....in other words the so called light motors seems to be more vulnerable or less reliable once very much used on strong ride...much different experience if compared with my previous experience Bosch CX Performance [ Cannondale Topstone Neo 1 Lefty ] ...but weight, drivability, noise...different.
For what I heard from few users the new Bosch SX seems to combine the durability and efficiency with excellent performance and reasonable weight.

Thanks for the interest and suggestions.

I presently ride a Trek Domane+ SLR6 with the TQ HPR50. I've logged 8,000 miles on it. Aside from the unusable phantom 300W, and the support erosion due to my low cadence, the only problem with the motor proper has been the rattling noise in stretches when the motor goes underutilized. On slower flat rides I still ride my regular bike.

Loaded with precautionary equipment, the Domane+ weighs 32 lbs. I don't welcome the thought of lifting something heavier onto a high hatchback mounted rack, and plan to stick with lightweight mid drive motor road bikes for as long as possible.

I'm in research mode and have been reading up on other motors. My understanding is that the Bosch SX and Mahle M40 favor strong rider input and high cadences, whereas I'm clearly in the low input and low cadence camp. The Avinox and Ride 60 support low cadences better. While the Avinox M1 and Maxon Air S show great promise, they are not likely to migrate to road bikes any time soon.

The insights in this thread provide encouraging feedback of the Ride 60. It appears that Fazua has come a ways toward solving the reliability problems. I interacted with Fazua some years back and found their responsiveness to be the excellent, to the point of remotely diagnosing and making a replacement motor and replacement battery available, as Blackvipergts also attests. The experience with TQ has been the opposite – scarce outreach and updates, automatic responses promising consideration followed by neglect - no feedback or explanations.

Blackvipergts, congratulations on achieving such an admirable level of power and conditioning. I'm a bit unsure as to which is your input wattage in your set-up.

Again, thanks to all, Rob

The Avinox and Mahle M40 are both big beasts of motors so the systems will be heavier, Mahle is very new so not many brands yet and all EMTBs. Avinox has some gravel bike take up, but small brands as of yet. Orbea use the Shimano EP8 in their new gravel bike Denna, it's good on low cadences though a bit heavier then TQ/Fazua etc but has had strong reviews, and yes the Bosch SX seems designed to deliver only in very high cadences.

Any models with the TQ60 as you are familiar with that system already? Would that give you enough power?

 

[stompandgo]

Now that we know that he rides a road bike, I was going to suggest the Denna, even though it's a gravel bike. With Di2, you can do amazing things with the EP8, which is a great mid-drive system. Also look at the Cannondale Synapse Neo Allroad, which uses the 55Nm 600w Bosch Performance Line Sprint motor, which can be user configured for up to 400% assist. Yes, Bosch Performance Line motors like cadence, but with 400% assist, I think that would meet your needs. Worth a try.
