comment rear panniers attachment catching in spokes
Similarly Altura have a decent hook that stays put on the roughest roads. My cheap pannier uses velcro which is fiddly and dirty to attach but works surprisingly well. If you're using a pannier with bungee attachments you might consider shortening the bike to increase the tension or giving it a bit more to hold on to. On some racks a bungee attaches to a non-structural part of the rack that could have a notch filed in it.

comment Buying mudguard and pannier together vs separately
@BPugh I'm inclined to agree - or to say "get the right rack and make the mudguards work somehow". There's a good selection of cheap plastic mudguards for everyday use, and they're easy to modify.

comment Buying mudguard and pannier together vs separately
@BPugh on the topeak super tourist (quite a nice rack if rather heavy, and some good bags for it) it doesn't even do that because the mud comes up too far back. I modded mine with the addition of a tail made from a very cheap plastic mudguard which made a huge difference.

comment Do DC HUB Motors For Electric Bikes use regenerative braking?
A recent question here was about using an ebike on a commute to the top of a serious hill. In that (rather niche) case regenerative braking might be of some use. If any supercaps replaced Li-ion batteries they would save weight - but even if they added weight, ebikes tend to have very heavy frames - an alloy frame instead of steel would soon deal with that.

comment Do DC HUB Motors For Electric Bikes use regenerative braking?
@Blam, it's 5000J of energy to go from 36 to 0 or 0 to 36. The only reason 1000W comes in is the assumption of braking in 5 seconds. If you could deliver 1kW you could theoretically accelerate from 0 to 36 in 5 seconds as well (ignoring losses, gear changes etc). You're right that there's no point pedalling against a regenerative system.

comment Why does the glue in a puncture repair kit dry up so quickly?
That's all very well, and I do this with neoprene glue, but it doesn't do much good if the glue is needed in your bike kit to get you home.

comment Are there any high power bicycle generators?
At a quick look it seems to be a normal hub "dynamo" (not really a dynamo as it's AC) max 3W (so not high power). The clever bit is in the cable, though it's probably only a rectifier and DC-DC converter.

comment What gloves work well for winter riding?
Too short for a real answer, but ski gloves are good especially for a ride that's long enough to get properly cold but not long enough to warm up again. Be sure to get them plenty big enough though, especially with thumb shifters. I've seen high-vis ski gloves in the bike department of a shop round here - they might be a good option as ski gloves are ften dark and not good for signalling.

comment Simplest and best way to keep water bottles clean and hygienic?
@CareyGregory or if they sit around for a while - by the time it's been drunk from a few times or sat around open to dry and gather dust the water isn't pure and stuff can breed in it. I'm not saying it will make you sick, but it can taste rather unpleasant. The dishwasher also does a decent job of getting road grime off the nozzle.

comment Is it good practice to wave following cars through when safe?
I don't often find it helpful when cyclists do this when I'm driving - I don't trust many people enough to overtake when they say it's clear. So I don't do it cycling. What I do do sometimes is ride wide through the tricky bit, then very obviously tuck in when it's clear to pass -- one example is on a stretch of my commute with verge rather than pavement (sidewalk) and which is wider and straighter than the previous bit - it feels like it gets more cars through with less impatient-to-dangerous overtaking than just staying out.

comment Breathable backpack
I've seen these but never used one - it looks like it would shift the load quite a long way from your back. I'm used to packing rucksacks with the heaviest stuff low and close (from hiking but it holds if you have to ride with it -- it's more stable).

comment Suggested tire pressure for an “overloaded” bike
With moderately large tyres you should be able to go up to the sidewall pressure at the back without the ride being too rough for the passenger. A seatpost-mounted child seat is supposed to have some flex compared to a rack-mounted seat; the question doesn't say which it is. At that much weight, unweighting the saddle to use your legs for suspension of your weight over bumps (and avoiding big bumps such as kerbs) would be a good idea. Realistically you're on your own legally unless it falls to bits on the way out of the shop anyway.

A single layer of heatshrink should do the trick. Or full-finger gloves, especially if the metal feels cold to the touch.

comment Brake lever grips
@Vorac it's worse than that on cheap v-brakes: The plastic bends so much the levers touch the grips without locking the wheel with recommended pad clearances and toe-in.

comment Why does reducing bike weight have such an impact on speeds?
"when tire design is the same, then wider is LOWER rolling resistance!" - for the same pressure yes, but the pressure probably won't be the same (for that matter that design probably won't be). If you mean even taking into account pressure changes, {citation needed}. But in the Q both were road bikes, I think we can assume similar wheels (and handling).

comment Minimal gear for dry winter riding in the city
You also need some means of carrying a lock or 2 (search here for locking strategies if you're new). Personally I tend to lock the helmet to the bike with my cable lock (2nd lock).
