You need to know what saddle height manufacturers are using to create the effective seat angle as that's how the effective top tube is measured.
That's why you can't use the real seat angle (centre of the seat post measurement) to compare bikes.
As a potential buyer I find this interesting.
I currently ride a large Orbea Rise (2023). I've just taken the same measurement (crank centre to top of head tube centre) and it's 795mm. On paper the geometry of the Rise and Amflow in large are practically a match.
For all we know early adopters may experience the best customer service known to mankind.:)
I've just noticed they have a 30-day unconditional return when bought direct from their website. That's pretty good and shows confidence in the product.
I too have a Rise (Hydro) - which I'd also...
I watched the Velomotion review and even he says the test bench doesn't replicate real life riding.
He had a lot of praise for the motor especially the power delivery - watch the last 10 mins.
Awesome.(y)
So looking at the Fox Transfer spec total insertion length is 288mm which is longer than the max of 270mm stated in the Amflow manual. Presuming the frame is a size L.
Out of curiosity can you measure BB centre to top of seat tube?
I'm trying to establish how much seat post drop I can run. I struggle with long seat tubes.
If the effective length is 450mm then that's ok but on my limit.
If it's the height as per the diagram then the effective length (centre to top) will be approx 462mm.
Does anyone know if the new 630W battery is compatible with the previous version of the Rise running an EP801?
Would be a nice upgrade with no weigh penalty.
