I keep wondering about the evolution of speccing parts for e-bikes. From my understanding, it went like this:
1) Full-fats came (80nm+ torque): Brands came with 2300 grams wheelsets (DT HX1700 at 29"&35mm), 1500 gram tyres (Schwalbe Eddy Current), heavier cassettes,etc.. To withstand the "power" was the main argument, not heavyness of bike&rider.
2) SL E-bikes came (35-50nm): Above not needed, let's get back to Exo Dissectors and XC/Trail wheelsets.
3) Latest full-fats, even more powerful than previous gens (120nm)... back to same spec as SL-Bikes; Exo Tyres and Trail wheelsets. Internet is awed at weight miracle!
So was the overbuilding paranoia unwarranted or what :- ) ?
When you actually take the system weight of DJI (Motor+Battery), it's actually surprising close to everything else right now on market (current-gen). It's just much more powerful at given package, but neither motor or battery is magically light-weight. All the weight-saving comes from the build, all to create youtube headlines.
wonder how much these are in the USA.. or are they not coming to USA this year? seems like they are pushing it more international only first
A google search returns this: "As of July 22, 2024, DJI drones are not currently banned in the USA, but the situation remains uncertain. The US Senate’s version of the 2025 National Defense Authorization Act (NDAA) does not include provisions to ban DJI drones, unlike the House version which incorporated the Countering CCP Drones Act. "
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.I wonder if they will sell the motor, battery and looming separately, once my 7th brose motor fails I'd like to say you know what, I'm gonna retrofit this beast into my specialized
I would like them to but I really doubt it, almost none of these motor manufacturers want to deal with the average consumer. Imagine the support headache of the average Joe trying to figure all this stuff out, ordering the wrong thing, over torquing bolts, pinching wires, not understanding electrical concepts etc. It would be a disaster I’m sure.Really hope they do, like how the bafang motors are.

I see a lot of people saying this, but honestly, what in that motor would have come from a drone at all… It’s not like they took a drone motor or something and slapped it in a bike, this clearly would have been a new grass roots project for them that likely wouldn’t have had anything other than maybe software in common to the drones. I’m not saying it necessarily will be super reliable at all, but just saying because they made drones that it won’t be reliable seems a little tenuous. Would we be saying this same stuff if it was just a brand new company making a motor system?Although the spec's are good, I don't see a lot of reason to assume that they will be super reliable. Drones are a very different application for electric motors and electronics to bikes. Although the drones are tough, they only fly for what 20 minutes at a time and then hopefully land smoothly 99% of the time. Users are expected to be careful with them and limit their exposure to the elements. They need to be running at close to their maximum power and efficiency for most of the time.
Bikes are ridden hours at a time, in terrible conditions and experience thousands of small impacts/accelerations per hour and several heavier/larger impacts/accelerations too.
They may well have done an amazing job, but only time will really tell.
I wasn't saying it will be unreliable. Just that we don't know how reliable it will be. Bosch is an even bigger company with wider experience and still has taken (is taking) a long time and a lot of iterations to become reliable.I see a lot of people saying this, but honestly, what in that motor would have come from a drone at all… It’s not like they took a drone motor or something and slapped it in a bike, this clearly would have been a new grass roots project for them that likely wouldn’t have had anything other than maybe software in common to the drones.

the questions you ppl have and not using your own brain. how many 185mm trunnion shocks are you aware of that have a hub longer than 55mm? exactly…What travel do you think you can get at the back?
Yeah, I am also kind of confused by the hype.Although the spec's are good, I don't see a lot of reason to assume that they will be super reliable.
The package overall is quite good if you're looking for a trail ebike, for enduro or serious stuff it's lacking a bit...
.....................
According to his statements and the settings he had in the app he was at 90Nm, 2/3 of max assist(cca 250%) and did 44km with 1608m of altitude gain draining the 800Wh to a complete 0%.
This would equate to 50Wh per 100m altitude gained.
................
For comparison at comparable conditions my 26kg Reign E with 85Nm at 250% Assist, Launch 5, + my 90kg can eek out 60km with 1900m of altitude gain. That's cca 42Wh per 100m altitude gain...........
The usual questions when comparing range:......................
Anyway the ebike future looks interesting ️
Hey Steve, I take range talk pretty seriously and know the variables that affect it pretty good, I wouldn't write all above if the variables wouldn't be comparable and here they are.The usual questions when comparing range:
How did your riding weight compare to that of the tester?
What about the tyres/pressure etc?
It is weird they chose to use a 36 and not 48v system, especially as a newcomer to the scene who should have been able to leap ahead of everyone else; Brose is just now learning the lesson finally and going to a 48v system after several years.Hey Steve, I take range talk pretty seriously and know the variables that affect it pretty good, I wouldn't write all above if the variables wouldn't be comparable and here they are.
That's why the Wh/altitude gain comparison, as all else(two bars, three bars, km, etc...) is completely useless info when comparing range.
As written I am 90kg ride ready + 26kg Reign E. I basically ride the same size Maxxis WT tires he does in the test, only my front is EXO+ not DD, the terain is also comparable and by his looks he is probably around the same weight maybe a bit more, although his bike is 6kg lighter.
And if you read to the end, I did write at the end it's the first tests and it's to early to jump to conclusions, but gives a first view also I am not the first saying the motor has high consumption, I did catch that somewhere on the forum or if not mistaken...
Will take this opportunity to include something I didn't include in my previous writing, maybe some interesting info for someone interested in the tech and the bike. This information is also from another german yt reviewer 2 months ago after Eurobike, he was one of first if not first to ride the bike in the woods and he is presenting it with one employee from Dji.
He asks a question how it's possible to achieve 1000W of peak power.
His anwser went somehow like this...We don't pedal in completely round motion, so our power input isn't round(the same amount at every moment). So when when we are in the power pedal phase the power is reduced from the motor, but in the dead zone pedal phase the power is added. As the bike has 10 different sensors that's measured so fast and power reduced/added so fast it's not felt by the rider, but what it does it enables to reach peak power of 1000W with still staying inside the legal limit of 250W average.
As I also wrote it is a 36V system, it's impossible to cheat physics, with higher wattage comes higher amperage. Higher amperage means higher heat, higher heat means higer energy loss = reduced efficiency.
Solutions to this are better cooling that can be passive-more mass-lighter motors are weak at this, air channeling(which no brand has been doing except Merida tried something).
Or
Higher voltage = lower amperage = lower heat = less energy loss in the form of heat = increased efficiency.
That's why the most SL ebike motors work on higher voltage, energy efficiency with smallish batteries and motors is key and that's why imo the future is in higher voltage systems, especially if people want more power at the same efficiency.
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 installed so you cannot mess it up. Provide a detailed spec sheet for every bolt required and a general install guide, maybe even a video or two. Honestly if you are capable enough to build up a bike from the frame you shouldn't have any issues build a emtb as the process is very streamlined already with other manufactures like bosch and bafang. And just a few short youtube videos to make things super clear and you are set.I would like them to but I really doubt it, almost none of these motor manufacturers want to deal with the average consumer. Imagine the support headache of the average Joe trying to figure all this stuff out, ordering the wrong thing, over torquing bolts, pinching wires, not understanding electrical concepts etc. It would be a disaster I’m sure.
The only way I could see them becoming available to consumers would be if one of the DIY frame OEMs like Dengfu or LC decide to become DJI customers and they could possibly sell a kit with a frame + electronics together. Still not sure if DJI would even want to sell to someone like that though, I could picture them only wanting their stuff to come on complete bikes, especially if agreements with other bike manufacturers might call for it.
Most current shocks and forks have a 50hr service cycle. But on an eMTB you’re getting 2-3x Laps in, in that 50hrs, regardless of fitness or skill level. The same goes for tires, brake pads and other consumables.Needing a tougher build is more about how/where you ride it. If you're doing flow trails all the time, then you don't need Enduro spec shit. If you're jumping it and slamming rock gardens, then you probably do.
