Thank you! Projects like this keeps the gap between corporations and people open.

Yeah Pedro, it's gotta be brushless, field oriented control, torque from standstill and good efficiency

Great update!
Some notes from a bike mechanic:
> It's absolutely crucial that the driveshaft is out of a stronger material than aluminium. Cranks are generally made out of aluminium, and you want your crank to break, not the driveshaft. Even if it's an open source project! So I'm happy to see you went with steel instead :)
> I think it is important you choose an appropriate engine for this build. Like others have pointed out: Brushless is the way to go. And I would opt for a flatter, more compact design, so it is easier to house under the frame.
> I don't know how you can make the bearing work. Bafang engines use a ratchet system, similar to the body of a cassette. Seems reliable enough, maybe consider something like that. Rollerbrakes and some internal hubs (Elevandi) also use the technique used in the bearing. Perhaps it is needed to design this yourself and incorporate it in your design.
> If at some point you could incorporate a torque sensor, that'd be great. Mid engines really thrive on that.
Thanks for sharing!

You are making one of the best projects in the world, and thank you for sharing your knowledges for free with Us. From Uzbekistan, Zarafshan city with love and respect for your job

wow, hidden gem of a channel this one. tons of cool videos full of open source stuff

Your trike looks awesome.

Nice project sir! I think you should really go with at least something like 7070 110kv brushless and a better torque friendly gear ratio.
My Italian channel is all about stuff like that if you want to take a look 😊😊
Can't wait to see v2!

respect!

This is the world i am dreaming about. Thank you so much!

So, beautiful work.

Thank you!!

Good job, looks like an awesome project

Wow, this is amazing! Thanks for sharing!

Thank you. I learn a lot from your project.

This is such a cool project!

Dam you are a genius, don't give up,you can make majica.👏👏👍😊

Great channel

slit in the clutch bearing (cut it once length-wise), pre-heated metal rail inserted in the housing, epoxy glue

Super stoked and interested!

Absolutely love every single video of yours! Keep it up!
