    That Speed looks great. Don't worry about age. Bikes are not like cars, that one looks hardly ridden.

    I'd say the Lexy is worth the extra. It has better (looking) componentry, especially replaceble chainring (good if you want higher gearing), aero rims, non-kid tyres, ahead-stem... It's a bit hard to...

    The comment that the pin rotates freely makes it puzzling that it simply won't drop out. Maybe there is a ridge in the pin eg at the grub screw location, that requires good alignment of the hinge...

    I haven't done the Brommie often at all on my work commute, but I think the Ti Swift is about 10% faster. I will try it out a few times this week, Friday at least, to see.

    I don't think "better" is the right word... some people want more of an urban bike while others are more interested in minimising weight while retaining gear range... or simply like a derailer...

    Did you undo the grub screw that prevents the pin from being extracted? At the middle of the hinge.

    I just made my spare Ti Swift with a SRAM Automatix with coaster brake. I am liking it much. Hardly using the front brake. On my other bikes I normally only use the front except in emergencies when I...

    Gear ratios are 62" and 84".
    Haven't weighed that bike yet... the hub gear is quite hefty so I expect 9kg.
    This is indeed the 1st frame. I fixed the problem with the seat tube alignment by careful...

    Made some springs over the weekend, and finally now the shifting point is where I like it. I haven't measured the shifting point speed but it is probably around 13-15mph.

    I see the Hasa F3 has horizontal fork ends, so good for IGH. I also see the rear wheel has 28 spokes so if you buy a 28H Automatix hub then you can use the same rim.

    Good job on the repair!

    It is hard to make a call that the repair is going to be good or not. The best you can do is start riding (suspect you have already done so) and form a view on how sturdy...

    One thing is very important: Get a bike with track fork ends, not vertical dropouts, or you won't be able to set chain tension.

    Check the steering bearing for over-tightness. The bars must turn completely free without having play. If the bearings bind a bit, this will ruin the basic balance act of cycling and make you veer...

    I just checked, seems #16 wire is just thinner than 1mm...! The spring gauge in my hub is much thinner than that, I think even less than 0.5mm.
