    Finished - 1500w 20" Electric BMX Build

    Cool! I'm interested to know how the wrapped 3d prints are holding up? are they all PLA? I've been toying with the idea of building an entire frame using some kind of combination of 3d printing and carbon fiber https://endless-sphere.com/forums/viewtopic.php?t=111541

    Custom frame for the Cyclone Coaxial motor

    Thanks! Life has been pretty busy lately but it's still ticking along slowly - I'll post an update when some real process has been made.

    Simple, open source middrive anyone can build

    Cyclone.tw and sickbikeparts both have a range of various freewheel adapters etc that may be of some use.

    3DE - 3D Printed Carbon Wrapped e-bike frame

    From what I've read a basic rule of thumb is the carbon should be the same thickness as if you were making it from mild steel.... so in the case of a bicycle that would be between 0.8 and 1.2mm thick in most cases (for the frame tubes, thicker for the BB etc) ...I will probably go 1.5 plus to...

    Just a quick clip of a new Carbon Frame I'm Designing Bg_gLKTSYpQ Similar specs to the previous one - this is just the initial conception - Cheers

    Best Mid-drive Motors in 2021

    OK interesting, Look forward to hearing more about your improvements - As you know I'm doing that exact thing 'building a bike around one' I think the Coax motor is a really good starting point and yes you're right in stock form it has some issues, I have a few ideas myself about some improvements.

    Best Mid-drive Motors in 2021

    Screen grab from website - Looks suspiciously like a cyclone coaxial motor to me? By reading some of the other posts you have made a bunch of upgrades to it? torque sensing for one? and a custom controller of some sort? Or am I off the mark entirely?

    Custom frame for the Cyclone Coaxial motor

    Thanks - it's just revision 1, once I have some time in the seat I have lots of plans already to make it better

    3DE - 3D Printed Carbon Wrapped e-bike frame

    I'll have a look at what files i have - from memory some aren't 'manifold' but still printed fine.

    CF or Glass Fiber over PVC Pipe

    Does room temperature cure epoxy (the type used for wet lay up) deform with heat after it's cured? If not I wonder if the shape could be 3d printed with PLA (coated in release wax before lay up) then after curing the PLA could be heated and shrunk to be removed leaving the external carbon shape...

    20s8p battery 20 groups of 8 OR 8 groups of 20 better?

    Ok - makes sense, thanks

    20s8p battery 20 groups of 8 OR 8 groups of 20 better?

    Thanks for the response, Yes - you are correct, but I don't think I explained very clearly - What I mean is: I could make a group of 20 cells into a 20s 1p 'pack' then connect 8 of those 'pack's in parallel to make 20s8p OR I could make a group of 8 cells into a 1s 8p 'pack' then connect 20...

    20s8p battery 20 groups of 8 OR 8 groups of 20 better?

    As the title suggests I'm designing a 20s8p battery. is 20 groups of 8p cells OR 8 groups of 20s cells better and why? I'm sure I've read about this somewhere but my brain isn't working today

    Best frame for stealthy e-bike build? Eleek Ekross vs. Qulbix vs. Vector Typhoon frames?

    You should check out the futr frames as well - made by the same people that make the genuine stealth bikes http://www.futrelectricbike.com/product/beta-snow-white

    Custom frame for the Cyclone Coaxial motor

    :lol: you're probably right. For me the driver is that for the same money as a few parts would cost from a local shop I could buy an entire sheet of material and make 5x the same parts... I guess growing up reasonably poor made me put a high value on self sufficiency that I still carry with...

    Not really any notable progress - I've been a bit distracted building my CNC... hoping to get her up and running over the christmas break... thanks for the push though probably just what I needed!
