Is range of amflow as good as mondraker Bosch system.

[David1960]

I am thinking of getting amflow pro carbon but worried I can’t get range of my Bosch mondraker 750. My mondraker can do 35 to 40 miles in turbo. Can amflow do same range. Most of mileages I have seen on Facebook show people doing not much mileage above 20 miles. I have my Bosch on max power 85 nm and get huge Mileages.

As mentioned in the other thread . You say that's in "Turbo" - which is totally the wrong mode to be in looking at your ride stats ..

82w average would suggest you're in motor off .

Or maybe .. eco ?!! Maybe ?

All turbo will give you is an erratic ride. You'd be better in EMTB.

Batteries/motors are generally down to physics ..

If you pull the same power from an amflow, you'll get about the same range/altitude per WH of battery.

Obviously that's not 100% fixed, it depends how you ride, what terrain you're riding on . It will vary rider to rider also.

Thanks. That’s really helpful. Why did you say at 82w motor is off.

Fantastic. Thanks.

Sorry, I had Sam Hill on the brain from watching the Redbull Rampage on the weekend in Tasmania, and commentators continually talking about the "Sam Hill Line".

His name is Sam Wordley. I've fixed the post.

I stand corrected.

Either way it's another product plug.

From the other thread as it's more relevant here :

What should average power be on emtb then if using correctly. Not really sure what you mean when you say I am not using emtb as emtb. Really appreciate your replies. Thanks

82w average seems like a very low average watt figure - in any mode.

In turbo it's quite hard to apply the power smoothly, so it's much harder on the drive train, especially when changing gears.

EMTB mode adapts more to your input in how much power it gives out, so you have to work a little harder than in Turbo, but the power is more controllable and the range you'll achieve will be considerably higher and it's far easier to ease off the pedals/power to change gear and then re-apply the power more smoothly.

It might be that you generally stay in one gear so in that case it won't wear your drivetrain too quickly. But, to average 82w you must be hardly applying any assistance yourself ? I think if you look at most rides on a normal bike with no motor, the watt figures would be higher than that.

From my experience, most people who ride in turbo do it to go faster and so they're also applying as much power themselves as possible - so the average power figure would normally be quite high.

I don't ride in just Turbo much anymore, but here's a Turbo only ride for example :

In this case, it's difficult to say exactly if an Amflow would give you similar range/altitude because it depends how much power the bike will try to output in turbo from very little rider input. It might react much more forcefully, in which case you'd be going faster, using more average power and would end up with less average range. I believe you can/or will be able to adjust the power settings in the different modes on the Amflow, so in theory, you'd be able to adjust it so it did match your Bosch range. However, if you wanted to take advantage of more speed/power, then you'd need to make sure the battery was proportionately larger on the Amflow compared to the Bosch to get the same range.

Hope that helps

Thanks that’s very useful.

You have to keep in mind though that Sam adjusts the calculations to the same size wh battery. Not total range.

It’s really useful but more of an efficiency comparison not full range test.

Did i miss it in the video, but there's only the Bosch Race not the standard motor?

 

[Doomanic]

What terrain are you riding to get that range? If I had to guess I'd say canal tow paths and tarmac. 3300ft ascent in 39 miles is almost flat, my usual rides are 3300-ish ft in 12-15 miles.

 

[daytrader]

I own a mondraker crafty Gen4 with 625 battery and get a range of 1400-1600hm
now with the amflow pl and 800 battery i get even more range . . but you have to decrease power settings in the app, because on default levels the amflow are much more powerfull and so the range will be less / or same as a bosch system

I have to do a fair amount of road and trail to get to where I want to cycle - up to Darwin tower.
