Excellent build, also very beautiful to look at; I hope to see a video of it in action. It's strange that the author encountered difficulties in soldering XT90 connectors; I actually never soldered more than a few of them but never had any problems; it is possible that either they were of dubious quality (far east clones with possibly sub par copper contacts?) or they weren't clean enough. Nothing that a good solder iron, as the author suggest, and good use of flux can't cope with.
For those in need of a good solder iron, avoid cheap no-name ones or Hakko 936 and similar clones and all those using the same stylus (there are at least a dozen different rebrands) because they all are bad: they indeed work with very small solder joints but will fail with bigger contacts or larger pcb tracks, although the power should allow them; the reason is always the same: too small thermal mass and bad thermal contact between the internal heater and the tip. Any used Weller WTCP will perform a lot better roughly for the same price, or check the Pinecil, which for the price performs really well and is also a 100% Open Source Risc-V platform.
About bicycles, unfortunately I'm too big for them; even if I wasn't overweight, my mass would exceed 100Kg anyway, but hope to see 3 wheeled EVs imported or produced in Europe. Someone here mentioned Arcimoto a while ago and now I'm in love with their Roadster model after seeing a video. Unfortunately, high price aside, it's US only at the moment.

Or simply use too small an iron for the job. XT90 isn't the problem here, more likely it is the fact that the wire drains heat so fast that you don't get to a nice temperature.
