Testing differences vs claimed are interesting but could be explained. We still don't know where DJI is getting their power figures. It seems in the EMTB motor world the big players go off power at the crank, notably not bafang though which is at the battery. From my prospective of high power...
Relevant comments below from WwC, that the bike will come to the USA in early 2025 and that other brands will have the system in the future not just amflow
From my understanding ebike-mtb power figures were either at the wheel or tested at the wheel but then because they calculated for drive train losses removing them in their figure. I'm not sure which one they are referencing for there figure though. I don't know what the German testers use...
Does seem to depend on the publication though, as Ebike-mtb's testing shows a different result. Unfortunately I don't speak German so it's not easily for me to follow exactly how they do their testing, so maybe the testing method is different, giving different results. I do see in the comments...
That's if you trust Bosch's 600w figure, which I don't. Ebike-mtb tested a gen 4 and found it will output nearly 750w at the crank, not even input wattage before inefficiencies. I've also seen a youtube channel test a turbo levo, same thing peaked 25% higher than claimed. I wonder if DJI is...
Not saying they don't or that this is something DJI started, just that I find it weird someone wouldn't choose a motor whos only difference is double the power, especially when you can lower the power to match it if that's what you want
Even if the 120nm system can be configured to only output 60nm in user defined modes? That way if you ever change your mind you can then access the power
I would love to hear about the pointed and well-reasoned opposition to this issue and the arguments they proposed. Personally, I can't think of a single reason that raises a significant concern that couldn't also occur with a normal bike, such as bad behavior. Studies have already shown that...
If you look at the E55 thread you will find I also agree with this, just depends if you are willing to do all the work to make a larger battery fit including permanent mods to the frame, vs a native fit.
@Daxxie has done the frame modifications to his E23, which is the same frame but a wider...
I would strongly consider the E55 for your needs, it has a a stock battery case of 56 21700's. If you use 6ah 21700's in that case you could get to 1200wh, and the E55 in large has more than enough room to fit a range extender, 14s1p would be another 300wh. I believe the E22 can also fit a 14s4p...
Everyone else pretty much covered it but rated power is basically how much power it can sustain without overheating in a set time, no law around how high you can peak. I believe for the EU it was over 30 minutes but I'm not 100% sure on that. I would actually love to find out more on how this is...
Doubt it will cause a whole lot extra wear, but if it was a huge concern dropping down to a 10 speed would likely be more than enough. Motors with more power (although not eu 250w legal) have been on the market for a while, dropping down to a 5 speed would be massive overkill
I mean Dji already has experience dealing with the average consumer and even DIY market (see drone parts they sell). As for issues that could arise during building I would say they just need to nail the process down for installation, keep things simple. Every cable one has one place it can be...
Really hope they do, like how the bafang motors are. Pick the frame you want a build it up yourself. That's where I usually am on here looking at the cool frame up builds in the DIY section.
Just do what the diy market has had for decades and put a switch on the charger to adjust the charge rate. Add a piece of paper explaining to charge on the slow mode unless you need it for best health. Which it seems like DJI is doing considering they list two different charge rates.
