Thanks for the photos, nice and tidy solution.

For what it's worth, crimp connectors including Anderson's have always been more reliable for me than soldered connectors. Most OEM crimping and pin tooling prices are outrageous. Plenty of affordable high-quality alternatives are available for common connectors. If a 150amp crimp connector with for...

Thanks for this. Such concise descriptions of circuit limitations/boundaries is very rare to find.

Exactly, Alan thanks for taking the time to inform others. Much appreciated and food for thought.

Nice job, must have a long range. What did you do with the thru axle swingarm to accommodate the hub? Cut slots and add a torque arm? If you could post a close up pic that would be great. Cheers

Good news, I'm new to ebikes and looking at a similar frame without shocks or forks. I'm also interested in suspension options, although I haven't searched for specs yet. Do you know the rear shock travel, eye to eye measurements, and fork specs? No need to check if you don't, I should do a bit of r...

Fame!

Not as good as your sultury radio voice

What a legend, AFIK one of the few members to post a thread about how to recycle pouch cells.

Glad more bits are arriving, will it take a week to look at freewheel threads? Seems a while but most good places are busy. Is your problem with the motor thread or freewheel thread? Gl with the fix hopefully you get it back sooner.

Oh I see that makes sense, could be as simple as over spray from painting. If you don't need a thread file a small pick or similar might be enough to liberate wayward paint.

Does the axle nut travel all the way down? Likely to be an issue with machining of the axle flats. Try working the nut up and down with plenty of lube (oh that's awkward). If not there is always room in the tool kit for a thread file or tap and die set. Edit: thinking out loud because I've never add...

Judging by the half-arsed effort that resulted in a wonky controller label I'd say proceed with caution Good luck with the set up looks pretty basic.

Nice IP rated JST connector available with multiple pin configurations.
6 pin male manufacturer part number JSTJWPF MFR PT 06R JWPF VSLE.

Hi, would you mind sharing how you developed the textured ABS? Did you use moulds or was it a handmade process? Perhaps I missed this in another thread.

Nice rig Thorium and a solid write up. I hope you have a great time, keep an eye on controller temps if you plan to give it a hiding. How did you source the battery? I have a spare 20s BMS but unfortunately, AFAIK it won't suit your 21s pack. Good luck

Love the build, looks like a metric shed load of fun. Love the porka in the toy shed.

Sorry to hear about your crash, it could have been a lot worse as you could have ended up under the following car. As above, unfortunately, you're not alone in experiencing this type of failure. Depending on throttle type I've also read posts (John CR, I think) about adding a resistor to clip max th...

Thank you, Chris, you share so much cool stuff. Leads to an interesting idea of tab connected fusible links attached to a cooled heat spreader that also improves ampacity. Next question is can desired cooling be provided via a fusible? If not, forgo the fusible link for improved thermal management; ...

Edit: sorry just saw details, glws.

Dave, thanks for the video. I'll address a couple ideas about noise. Firstly, your voice provides a great reference for powertrain sound. Powertrain sound seems very low during in the cadence demo. IMO speaking in "motorcycle mode" and a view of camera setup might help customers to better ...

Hot dam Foolsday that was a very insightful post I read the cells are welded to nickel terminal plates. Is that pure nickel at 0.13 mm? If I read correctly (aplogies on my phone) the heat spreader was directly affixed to the nickel terminal plates? Cheers

Perhaps the temperatures were logged across the pack?

Dtx, Dave, FastJohnny, thanks for posting your decision considerations. Understanding these decisions helps readers evaluate real-world consequences of bolting on a such a high torque high power system. From my perspective of evaluating mid-drive options with experience limited to a 5kw hub, I belie...

Take a bow you deserve applause, for those of us considering alternative mounting please add separate motor, drive, and controller dimensions to the webstore?

Very interested in the cell fusing and materials used for statement "cells are actively cooled with a CNC machined cooling plate mounted to the terminal plates through electrically isolating material'' Thanks for sharing.

There are lots of dyno types; inertial (only mass, but not capable of performing steady tests), water braked, eddy current water cooled, friction dynos, etc. Hi E-vektor, from your posts I read you have experience with dynometers. I'm interested in a DIY solution for an eddy current braked dyno. Ha...
