Review 2024 Amflow PL Pro 800 wH

[David1960]

Yes we don't know what's round the corner enjoy but take care folk are crashing every week, me as well

Really what happened.

 

[Binhill1]

Really what happened.

I fell off and had silly crashes more times in first two years of having a Ebike than I did in over thirty years of off toad cycling. Only had one four years ago that did damage broke some ribs. I had a very lucky escape in November at Loch Affric going fast 20 mph ish on quiet flat downhill nothing technical. Wet patch and front wheel just went hit ground really heavy bruised side of thigh and outer shoulder but ok , probably 7 miles from civilisation .

Unfortunately I broke my collar bone 2 years ago. Caught side of pavement doing very slow speed and fell over. Easily done.

 

[David1960]

Yes mate did his shoulder in November then a month later out for our xmas meal i thought he was pissed. Got checked out at hospital that day he was told he'd had a tia in afternoon and a mini stroke a wee while ago. Back in action now so about 6 weeks after tia it's taken.

Not trying to outdo anyone! I had brain haemorrhage 6 mths- after banging my head on boot of car. Had slow bleed which did not realise till I lost my speech. Drilled hole through my skull to drain it. Back cycling !!

Don't let little scratches put you off, it's part of EMTB !

In the last 6 years I've fractured my skull, Pelvis, both collar bones, sternum, all the front ribs and most of the back ones (a horse did the others in the same time window). On the bright side, even if you're stupid you eventually learn from your mistakes and with a mix of better protection and learning to ride more within your abilities .... you hurt yourself less (in theory).

Back to your range questions. If you consider a Bosch in Turbo is peaking around 600w. Your ride average is 86w, so a lot of the time you must be at the assistance cut off. The Bosch eases off power near the cut off, so even though you're in Turbo, you're not using all of the power - only a fraction of it for most of the time. The Amflow behaves similarly, so assuming you ride similarly, in theory, you'll get similar range.

I still think you should use a different mode though if you can as your cassette usage is high, which is normally poor gear changes under power (which will happen in Turbo - high power/long overrun=hard to make smooth timed changes). You should be aiming for smooth changes and at least 3000km especially as a lot of your ride is on flatter easier surfaces.

yes you are spot inspector poirot - absolutely perfect assessment. Is it no good going over the cut off or should you always stay at speed that uses motor. I usually go to cut off on flat with my riding - thinking I am saving battery.

 

[David1960]

Also if I kept speed below cut off would that give me longer use of chain and casette.

I don't think so. Not unless it's "waving" on the cut off for some reason - ie, spiking power on power off, which it shouldn't be. It should be fairly smooth at or near the limit. Highest wear is normally when changing gears - especially when under power, it's learning to ease off, feel the assistance ease, change, then back to hard pedalling (or harder) to bring the assistance back up. It can take a long time to build that feel and adapt to the timing until it becomes second nature.

I run derestricted sometimes to test motor power/battery and motor temperature loads and limits and don't notice any higher wear.

Brilliant glad your OK now.

Sorry - got it wrong - meant to say -am I wearing chain and cassette out more by cycling above cut off point. Should I always cycle below the cut off speed.

My mistake, no, riding over the cut off will be fine. As you say, you'll get more battery range But proportionally you shouldn't experience any more relative wear.

 

[Binhill1]

Never mind the technical stuff back to old codgers failing off bikes etc. Met these two up my local hill ( Binhill ) . They had a great time out of the care home with two young carers for a few hours . So there is life after the Ebike.

You are fantastic. Learnt so much. Thanks.

You might know what this is Zimmerframe. Out yesterday on Levo put a bit power on peddle get a crunch noise as if it was jumping the chain or freewheel???. This happens occasionally once a month maybe. To me sounds feels like rear but could it be motor ?. I had new cassette on my old original wheels as other wheels getting a service but I has done it on the Hope wheel as well. Any ideas.

Could be the belt slipping, but think that's more of a Ziiiippp. Could also be the cassette slipping on the splines, or loose cassette (check its tight - but maybe check the splines at the same time if you're doing that). More likely though it's an older chain with the newer cassette so it's slipping sometimes maybe ?

Thinking similar only does it once when it does it though. More likely on the road and when cornering to go up on pavement. Strange one. Probably never know . Thanks

regarding range, I found it pretty interesting, that when riding with my buddies on a bosch (when they are riding on turbo, and I am riding on turbo), we get more or less, the exact same range, with more or less, the same % left. Of course, I am putting out more power, with more battery capacity, but still...its pretty much the same.

That’s really interesting. I would have thought I would have to drop power down when cycling with my friend who has Bosch cx motor. But based on what you are saying may be not. Because was worried I might not get same range as him because the power off the amflow in turbo is higher.

You mostly won't ride in turbo. I can easily keep up with my Levo in turbo by riding in trail on the Amflow. I did some timed tests up a 2.5km climb and the Amflow in trail still slightly beat my Levo times.

The Amflow is a great bike no doubt about that, i dont mind a bit of flex on the back end. But the one point i dont like is that when hit hits the UK limiter 15.5 it feels like someone pulling you off the bike, none of my S of the post 5 years were like that all very smooth an progressive.

The Amflow will improve. Mine was extremely draggy when new. I contacted Amflow and they told me it's the motor seals that need time to ride in. After 280kms it's much improved and getting close to how my Levo feels over the limiter..

A dab of silicon grease behind the spider will help a bit as well.

I will say that with the motor off there's still drag. So running out of battery won't be ideal. And over the limiter cadence matters. More drag at 60 than 90rpm.

Thanks. I am going to try trail mode next time

Thanks. I am going to try trail mode next time

Also in my tests yesterday I repeated the same climb 4 times. 2 in turbo and 2 in trail. 2.5km 250m elevation. I'm 100kg in kit. Average gradient was only 7% though.

Trail was 8 minutes and used 8% battery.
Turbo was 5 minutes and used 12% battery.
My Levo times are close in turbo to the Amflow in Trail.

So I use 50% more in turbo than trail, which makes sense. You'll still hit the boost button occasionally, which is quicker again, just to see the look on their faces as you sail past them.

Yeah, I agree, ya know, I have found you definitely don't need to ride on turbo with your buddies on a bosch,,shimano, or similar, ....well......unless your buddy that you are riding with, has Olympic skill & fitness....

One of my best friends, (that I ride with most of the time) , has that, ....Olympic skill and fitness....so on "trail," I generally can't pass him, but I can easily, no problem, stay up with him, on "trail" mode,,...however on turbo, he will eventually, bite the dust.. as soon as we hit the uphillls. If you have skill, but you are too "old" to have Olympic fitness, ....meaning you are over the age of 20 something... .... the bike makes up for that. You feel like, and can ride like, that guy Ned Overend.... WAY back in the day, ... super fast.....If you can have the skill to ride like Ned, with this bike, you can do that, even if you are "old", without the fitness.. OMG, so fun.

My Olympic skilled Buddy, after a few rides, said... "Man, I am going to get a crazy workout, trying to catch up with you"........he is right.

Love this. I am 63- with amflow I am now an Olympic athlete - who would have thought ?
