Hub motor as mid (illegalbike) 6000-12000W / 33-35kg

I like how you made the video in front of a gas station :wink:

I'm glad that you appreciated our humor

Damn Russians I'm going to get a submarine I'm going to come over and I'm going to steall that bike. and declared it was an American made USA .
of course if I want to get a submarine I'm going to have to ask Columbia that they would help me.


good job

 

[999zip999]

Colombia has the best submarines

good job

in this case I will add a mount for a Kalashnikov assault rifle and a pair of ground-water torpedoes to the bike


thanks

Mr illegal, could you share some details of how you've constructed the main pivot? Looks very tidy, but the bearing axial loading etc?

in the last video I demonstrated the main pivot, maybe it will be useful for you. The motor, frame and swingarm on the same axis are difficult for mass production, the next frames I will design with inrunner motor

Unfortunately my Russian isn't great. I watched the whole video to find the bit I think was your explanation but... Didn't really get it. There's no English translation or subtitles on YouTube unfortunately.

Would be cool to see this mass produced. Your plan to sell them? How much?

I think he made the frame holes for the swing arm large enough to push the motor axle sideways in (first on side, than the other), than he'd clamp the swing arm around the axle flats, and finally slide-on the bearings on both sides + that tiny bolt to hold everything together. Smart but certainly not easy to build.

Hi, awesome project, seem to be a really good machine.
you made it on aluminium, what nuance? did you made thermal post treatment after welding?

 

[ZeroEm]

I'm interested in how the motor is mounted and lock into the swing arm? I see some pictures and have ideas in my head but would like a better look.

Hey Dmitry, another question - what's all the software you are using for design? Thanks.

hi, i didn't learn heat treatment, but i'm cunning, so i used an aluminum alloy with 5% magnesium. This alloy does not require heat treatment and is easy to weld. Alloy AMg5 or another name 5056

unfortunately, all frames of this version are sold and I cannot show this unit disassembled, there are several preserved photos from different angles

Hey! I use 3DSMax for design, as can quickly draw a model. And I do the calculations and CNC preparation in SolidWorks. Suspension calculation in the program Linkage

 

[ZeroEm]

Thx, got it. the rear swing arm clamps on the axel, and the axel pivots in the frame.

ok thanks you, unfornately in france there is no 5000 series tube seller...

 

[illegalbike]

another eternal hub for 10-12 kw mid motor ebike with 4 industrial SKF bearings and anthers

 

[Hummina Shadeeba]

are the frames for sale in the near future?

 

[TorontoBuilder]

I love your builds, but even more I love the videos of you riding at high speed with very little noise.

 

[Hummina Shadeeba]

i cant speak russian but at minute six as you point to the axle it sounds problematic. https://www.youtube.com/watch?v=sEaH_lAp8Jk
im guessing it's problematic attaching the hub motor's axle, which is both threaded and with flats, to the front of the frame. Im guessing you banged a metal tube on the motor shaft ends to make round shafts for bearings?





Using a hub motor as mid drive seems ideal. Why are you are interested in using an inrunner next?

the nut itself has a bearing fit.
one frame came to me for maintenance, soon I will be able to disassemble and show the motor mount

I want to try to make different frames and find out which is better

 

[Hummina Shadeeba]

Yes

How much and how soon


everywhere selling the motor says its max rpm is 600. I don’t know ur gearing but think u said 2:1 and looks fast. I wonder what rpm you do and why they state 600rpm and if in a built wheel the spoke tension would be added to the force but when running the motor bare as you do.. what you think?

 

[ZeroEm]

Can not go faster than unloaded speed. It will be up to your Voltage/motor Kv. Wheel size will not be an issue.

[Hummina Shadeeba]

I mean what is the max rpm the motor can mechanically take before flying apart.(what rpm would be electrically ideal is another question). And I think all the sellers I’ve asked are misunderstanding me too and bet the motor can do way more than 600rpm


It’s 638rpm as they advertise it with the 20” wheel so they surely aren’t answering the question and likely don’t know.

((They told me they’ve tested it to 930rpm))
