I did today, on my wife's brand new Amflow PX Medium. I set it up fully the same as my Kenevo SL, with same ZEB fork.
Here is comparison for anyone:
- This bike must measure geometry different to other brands, or to Specialized. The Medium Amflow with 455mm reach felt almost two sizes smaller than my Medium/S3 KSL with 460mm reach. And I don't mean seated position, but actual reach while standing on pedals. I will try to measure this manually because something doesn't add up. The bike is super small.
- It's not that much front heavy as I expected, the 700W battery is fairly well balanced into frame.
- It's super smooth in delivery, ridiculously well. I would not call it unnatural, I would say it's absolute state of art, it's miles above every other engine I tried. It has zero unintended overrun, something Mahle engine with the single magnet just cannot compete with. But it does have quite pressure or what to call it when you run into 25kmh limit, unlike the Mahle which I never even notice. I would not call the engine pleasant to pedal in off mode or after limit.
- I tuned my wife's bike to be 21.5 KG (pedals included) with older ZEB and still the same heavy supergravity radial tires mostly by carbon wheelset, carbon bar and tubeless setup. To get this under 21KG would require trail setup which I am not fan of.
- Even with 170mm ZEB and mullet setup, it rides like trail bike with quite "above bike", not "inside bike" feel. It's not mini-enduro in any way at all, which surprised me. I wonder if it's the Float-X tune or what. I feel like the BB could be lower.
- And ultimately, even for such light-weight full-fat setup, the bike is very much full-fat in nature and behavior. I am not sure I am convinced... I wasn't super awed. I was ready to ditch my Kenevo SL and get on DJI bandwagon but now I am not sure. That light-weight experience isn't there. My KSL is almost 20KG with pedal and yet it feels rather like normal bike. This at 21.5KG does feel like every other full-fat, just super refined.
So yeah, DJI is the next best thing and other engines may as well stop selling, but SL category isn't dead as I thought. Right now I will still keep my Kenevo SL for some time as I ponder my upgrade path.
