EDIT: I wonder if the mtb brand ambassadors for Bronco will start spruiking the Bronco bike 🤣😂🤣

Why do car companies keep doing this? Do they really sell any?
 
Just saw Pilg's new eeb - damn the tech is moving quickly ; I cannot believe how normal it looks. I shudder to think how much this will cost in aussie pesos :eek:

A month or two ago I started seeing Amflow ads on FB and was wondering who TF are they, hyping up these bikes with no pricing info. Then went down a YouTube rabbit hole of emtb videos thanks to this thread. They do look very attractive with some clever tuning options and a nifty display thingy. Wonder if Amflow will do their own version of an MGU

The 'possible' big issue I think is Aussie law and other countries specify 250w max at 25kph. Now the 25kph is fine but how does this peak power go with the law. They can push the boundaries like all other manufacturers but at some stage it will cross the line. Bosch will give you a few seconds at 600w-85nm at high cadence. The Rocky Mountain has the highest power at 108nm.

Boost mode on this DJI, gives you 30 seconds of 120nm at 1000w :oops: That is nutts from such a small, light motor and battery. It is literally a game changer. I've watched a lot of Jonesy on a load of EMBN vids and sometimes think he is playing good shit down to keep manufacturers happy, I have never seen him, nearly speechless.

Sams bikes video says on sale here next month, as you say everyone goes way past 250W mark stuff knows how they work that out

Very aware of the limits but where is the line on boost.

Next we'll have bikes that have a MCR of 250w but a press of the boost button gives you 3000w for a minute.

The flaunting of this has been minimal to date with boost being pedal assisted by rider power at a certain cadence for a few seconds.

NSW is a bit different, "An electrically power-assisted cycle has a maximum continued rated power of up to 500 watts", whereas other states are 250W.. up to 25km/hr..
but up to 200W, there are no speed/assistance restrictions... (ie, is ungoverned)

https://www.transport.nsw.gov.au/roadsafety/bicycle-riders/ebikes
https://transport.vic.gov.au/road-rules-and-safety/electric-bikes

has this https://www.dji.com/au/avinox#160830
"In Boost mode, riders can enjoy a max 30 seconds of 120N·m drive torque and an instantaneous max output of 1000 W,"
3. 105 N·m is the sustainable torque output of the DJI Avinox M1 Drive Unit. The DJI Avinox M1 Drive Unit has a rated power of 250 W.

so.. for this DJI, anywhere is Aus is OK

I did wonder how that worked. since all motors are well over the 250w in peak power. So, I assume that a motor can't run at that full peak power for very long or is it all a bit of a gentlemen's agreement and no one really checks the output?

Yeah, it always concerned me that the attraction for manufactures to always to be bigger and better, would lead to an ever-increasing arms race of power in pedal assist Ebikes.
They have well enough power, just make them lighter and more importantly more reliable and serviceable.

The peak power element seems to have been given the blind eye so far, given that is just a second or two with decent rider input. The new Bosch CX Race has a race mode with 400% of rider input, plus the 2 wheel revolution run-on after pedalling has stopped. There's a few pushing (over) the limits currently with innovation. This DJI motor seems to have hit every limit out of the ballpark.

1000w for 30 seconds is massive. At one stage on an all out effort my 5 second power was just over 1000w, in the last 90 days with a couple of races and a few green jersey sprints its 660w for 30 seconds. Its nearly hard to fathom a bike giving 1000w for 30 seconds then adding the rider input during the boost. Drivetrains and chains are creaking at the though of it.

The flaunting of this 'peak power' on ebikes for hill climb racing may force a legislation change to include peak power limits if the boundaries are continually pushed.

I think the law will look the other way a bit.
Many bikes are exceeding 250-500w already and where there is money involved it usually wins.
Money speaks.
Our mad friend keeps talking about Amflow and it is an incremental improvement but small powerful motors dont necessary have a long life.

That's another reason why if they are going to use conventional bicycle drivetrain we really don't want more power. Chains, freewheels and cassettes struggle enough as it is with a full power bike.
I can see it though; marketing won't be able to help themselves and will want to one-up the opposition and to be able to claim the most powerful title.
If all Ebikes currently had the 35Nm of the old Levo SL, everyone would be totally fine with it but give the hint of a bit more power and it's like a carrot on a stick.

I'm pretty keen as well to be honest but will wait and see how things go.

Will also be interesting to see how the warranty is worked. DJI have a good reputation on their drones and cameras but I cant find any authorised Amflow dealers in Australia yet.

Vorsprung does not like the trunnion/clavicle mix.

I get 1000km from a Linkglide chain and they are supposedly the longest lasting available. Faark, we'd be down to 1 chain a month with the power on this bike, popping the boost button every 31 seconds :D
 
Have to appreciate the effort that has been done to help with this yearly problem. Kudos for giving it a go.

I am still 50/50 if I'd rather the thrill of the chase and run the gauntlet tempting the evil bird to peck off my ears.
On a brighter note, seems to be proven that we don't really need ears in order to wear glasses.
