Back to 16850 cells: here's a really handy configurator website for custom packs based on individual cells.

If I do go the 16850 route, I can fit 10kWh+ in easy.

BMW modules trial fitted to modified Freccia frame.

Nice. Interesting to know that they clear the narrow bit near the headstock - that was looking very tight on my measurements!

They won't clear the engine subframe.

Oh wow, they fit very well between the chassis bars.

@clanger9 how are things going on the project, any progress? Not many bikes here, so I'm kind of curious...

It's sort-of on hold at the moment until I can get more workshop space. I managed to get 12.5kWh / 60kg in the frame with enough space for the rest of the bits (boy is it tight!). Paul Compton is totally right about the lack of space in these things. I have been a bit distracted by the Ultraviolette F77, which is basically the exact bike I am trying to build, except it lacks onboard AC charging. So close!! Maybe I will wait until someone crashes one so I can grab the running gear...

Cool, nice packaging, never thought of stacking at an angle - probably because the hub motor makes that bit easier.
Have you selected a motor yet? On Damien's discord Jamie (@bigpie) posted a picture of the Outlander _front_ motor (which might be small enough) to stay in the OI ecosystem.
Unfortunately there are no decent pictures on Google that I could find, let alone dimensions, but the Wiki has some details: https://openinverter.org/wiki/Mitsubish ... _Transaxle

I was planning to use this one and retain the existing chain drive, but with 27KV windings to avoid an additional reduction gear:

However, I don't know for certain if that idea will work. If not, I'll need a reduction gear and cross-shaft...

A hub motor would make life a lot easier, but lightweight 20kW+ hub motors don't exist (yet)
