Yes, and two possibilities came to mind for doing the battery differently.
A TSA-compatible 99 Wh power brick or two, suitable for checked and carry on, providing limited duration and assistance, but being at hand.
And a COTS "portable power station"[1], which can be ground shipped to meet you at your destination, from home, or from a store.
The ideas are to optimize the bike for shipping by removing any trace of the battery from it. And to optimize the battery for shipping and availability by going generic.
EDIT: Another comment[2] observes the battery in the post is available from Home Depot, so that might suffice for COTS generic availability. So an airline story might reduce to: leave the battery at home; attach the conversion with velcro instead of zip ties (or bring snips and a bag of ties); unbolt and remove the conversion before check in, and bag it separately from the bike; get a new battery at the destination, by visiting or shipping from Home Depot; and put the conversion back together.

- sudosysgen 5y agoGood luck getting usable range out of two 99Wh batteries with such an inefficient drivetrain.
- mncharity 5y agoAh, interesting, the article doesn't seem to mention range. This comment[1] reports the article battery as 160 watt hours, so 2x 99 Wh might be an upgrade. One use case I pictured was last leg after airport arrival when traveling minimalist and budget. As a transportation alternative/supplement to mitigate last-miles time/$/hassle cost.

"While most airlines do not have a firmly defined maximum number of batteries under 100 Wh that can be brought aboard, we'd suggest travelling with no more than 4-5 LiGo's per person in order to avoid extra scrutiny. We have had customers travel by air with as many as 12 LiGo modules on them, but we wouldn't recommend that as a matter of course."
