Aden Powerkit Sport V2 - 1500W Spoke drive

[neptronix]

Hasn't been mentioned on this forum yet so i figured i'd kick off a thread.

https://aden-sports.com/powerkit-sport/



2kg ( 4.4lb ), 1500w max, 40kmh ( 25mph ) top speed. Uses a 36v battery.
90NM of torque, pas or throttle capable.

25mph only requires about 500w, so this extra 3x power on tap to climb should make for good hill climbing power.
Could sub for a mid drive.

$1600 USD / 1500 EUR for the drive unit, battery is another 500 EUR

Video of installation:

My thoughts? this would be worth the price for me if the drive mechanism could handle 48v. 2000w is where things start to get interesting for me.

I haven't tried to compare them yet; I wonder what design improvements they made from the original system?

ADEN-Sports, Power Kit Race (Review+Pictures)

Hello everyone, there are many ebikes, but only a hand full like this one. Thats why I would like to pass on my experience and share my passion for the concept. IDEA: Take your DH-bike and convert it into an electric MotoCross bike within only a few hours. My Bike: Its a Solid Strike L/XL...

Quieter and a lot less power!

Oh if we want to talk about single geared drives then we should also mention:
Aden Powerkit Sport V2 - 1500W Spoke drive
This has a 500w max version that's a bit cheaper.

It appears they don't ship to the US?

 

[neptronix]

I updated that thread so we don't end up going too off topic here.

 

[neptronix]

Emailed them.
They say it won't run on 48v.
They say they can ship to the USA. Therefore they may ship to other countries.

Is it wateproof? I see like coils in the stator I dont thinks thats wateproof or am I wrong

90NM of torque, pas or throttle capable

It appears the pas sensor is not included with the kit? And the one sold is 1 pole? I wonder if a 12 pole or better can be retrofitted for more responsive pas

The description makes it sound like that might cause some interesting behavior, since the system will think you're pedaling 12 times as fast.
"The PAS system enables assistance based on cadence, meaning you no longer need to constantly operate the controls on the handlebars (thumb lever or throttle). Assistance is now provided based on the pedaling frequency (rpm)."

It would require modifying controller parameters

I'm not familiar with the controller, but if that's an option, then sounds good. I wonder if there's enough slack in that cable to place the sensor near enough to the bottom bracket. Might be tight depending on the frame's chainstays.

I'd have a hard time not voiding the warranty and plugging a VESC in it and running it on 48v in the name of science.

Rim friction drive is an improvement. Add a "toothed" profile to the rim wall and you're in business. Could be nasty noisy though, and requires grease, and greasy rims would be a hard sell, despite making for simple maintenance.

Unless you ride indoors (velodrome, etc) where the dust is filtered out of hte air that would be hard on the gears as the grease accumulates dust and grit which then grinds up the gearing. (here in Phoenix there's a lot of flinty dust, so I don't even oil or grease my chains, and they last far longer that way than if I did).

This thread:

What a dumb looking bike

Go for it, @Chalo

endless-sphere.com

shows one possible example of this kind of drive, and while the gearing and rim have a "cover" I could pretty well guarantee it'd be easy for dust, dirt, etc to get in there and do this. I don't know if they grease the teeth or not; I wasn't paying close enough attention to the disassembly video.

You thinking of getting one? I'm likely going with the bikeon bc of ts. Also they said it can run 52v

Maybe you should wax them. See Zero Friction Cycling for test results. Silca and Ceramic Speed do good immersion waxes, or drip waxes if you can't be bothered. Wax doesn't attract grime nearly as much as oil.

Would be tough to do an immersion wax on a whole wheel's rim gear.

And the grit that gets in there would still be pressed into the wax by the gear teeth, and then still grind up the gears.

I dunno.
It looks like you can buy all the drive parts from them.. so you could recover from blowing the gears if you run 48v anyway.

On the other hand, i notice now that both sides of the case are open... lots of opportunities to ingest dust/rocks/water. The company says it is no big deal, but.. i have my doubts!
