Romancing with Fazua? Interesting.
I think so too. Not my cup of tea, but I can see there might be a few people at Specialized beginning to sweat.

I like the idea =no indication of pricing yet?
430wh battery means fairly regular recharges I'd imagine.

Think they weigh about 18kg.
Motor (60Nm) AND 430Wh battery weighs about 4.3kg. https://fazua.com/en/energy/ride-60/
Not quite as greedy as a Bosch CX.
You might get a bit more range on this one though

The UBN 5 ticks a lot of boxes for me: discreet, belt drive reasonable battery life, integrated lighting, but not sure I'd be willing to pay R&M premium pricing for this. Intrigued to see where this lands pricewise.
I'd be interested if there is any big brand cycle manufacturers that are doing that type of spec

Not necessarily Sam. The lightweight e-bikes with less powerful motors (like all Specialized SL ones and Fazua) tend to consume far less battery than their full power cousins.
As I own and ride my Vado SL a lot, I have gathered a plenty of statistical data. Let us look to the performance of a lightweight vs full power motor e-bike for similar rides:
- Vado SL, 116 km, 244 m elevation gain. Battery consumption 436 Wh. Battery consumption factor: 3.75 Wh/km. Average speed of 20.4 km/h
- Vado 5.0, 117 km, 224 m elevation gain. Battery consumption 747 Wh. Battery consumption factor: 6.35 Wh/km. Average speed of 22.7 km/h
P.S. My own contribution to the SL ride was slightly over 50% while it was a tad less than 30% on the full power e-bike trip.

Hello Stefan.
Do you have data on your energy contribution for each of your two rides?
Cheers

Yes! I indeed do!
- Vado SL ride: my own energy contribution was 443 Wh
- Vado 5.0 ride: I contributed with 312 Wh.

Awesome - thanks for sharing Stefan.
This aligns with what the sales guy at Specialized told me too for the Turbo Levo vs Levo SL......
In te end I went with full version of Turbo Levo, love it, but great to see your own data analysis above!

Yeah, I saw that debate.... are smooth welding joints really something to get hung up on? Never made sense to me.The particular portion of people who have been waiting for eternity to be finally seen on an R&M with smooth welding joints probably won't do that

Sam, if I ever wanted to buy an e-MTB again, I would go with the full power Levo, too. It is hard for me to even imagine my
Which I made on a Giant Trance E+ Pro.Thanks Stefan.
Adjusting for differences in average speed, doesn't the data indicate that the rate of total energy use (bike + rider) is close to being the same and the that V 5.0 is using more energy because it's providing greater assistance? Set at a higher level of assistance?
Interesting.

Hmm...
The Vado SL ride used 879 Wh, while the Vado 5.0 one took as much as 1059 Wh. I cannot interpret these data. I can only guess the cruising speed for each of the rides was different. As I can remember it, the Vado SL ride was very steady on speed, and 25 km/h was never exceeded. Meanwhile, the Vado 5.0 trip was full of high speed bursts (slow ride off-road, fast ride on the pavement). One thing is sure: higher assistance on the full power e-bike (with twice as much powerful motor!) replaced the cyclist contribution greatly.
Now, let us talk on the UBN. The actual function of a city e-bike is a short commute, or perhaps a ride to a cafe or library or perhaps a small grocery shopping. The UBN battery would hold a lot of time! If I only used my Vado SL for grocery shopping (my typical round trip ride is 15 km), I could probably re-charge my e-bike every second or even third day!

And now, the best! During my early ownership of the Vado SL, I let a female friend of mine ride my Vado SL for a long distance trip. She is an extremely powerful rider (the material for a competing gravel cyclist as it turned out later). She rode Vado SL assisted uphill/upwind for several kilometres, and then switched the assistance off totally. See the statistics:
She used as little as 67 Wh from the SL battery!
If the Fazua system turns out to be good and reliable, I see a great future for R&M UBN e-bikes for the richer part of the e-bike community! Very promising!
