comment First time commuter needs advice
"same route" - I'd say try a range of routes at first before settling in to 1 or 2 regular routes. You may well find that if you coincide with school drop off your regular route becomes difficult or dangerous because of bad parking and another route may have a tendency to ice in frosty weather. So know your options.

comment Trailer connection, off the shelf parts and proven performer
I was thinking of the surge brake question and remembered that there was no good conclusion - but thought you might need something. I suggested an electric braking approach there - for a completely non-connected electric brake you could use a sensor for a bike computer and actuate on a maximum speed (i.e. maximum pulse rate).

comment Trailer connection, off the shelf parts and proven performer
A few things strike me as being issues: Is the PVC pipe really durable enough given shifting loads? What happens when the slope changes - could the bow or stern bottom out (looks like it to me)? How does it handle down hill (I'd consider some form of drag brake on the trailer that you could set at the top of the hill to provide some friction - even a spoon brake)? How would you repair all the custom parts and the dolly on the journey? Can you actually go round corners? It looks like a nice simple solution, so these thoughts are meant to help in limited words.

comment Stationary bike calories
@mattnz it's a quick and easy way to compare sessions - reasonably reproducible on identical machines and at least better than a subjective comparison between two different machines or exercises.

comment Which is the safest side to place a foldable rack-attaching bike basket?
A folding basket is more likely to fold than protect anything - unless the contents act as a cushion.

comment How to clean and brighten reflective wall tires
Mine are Schwalbe rather than continental but while they don't look perfect after a normal soap & water wash with a bit of a brush they're almost as reflective as new after 3000 miles of commuting. I have been known to use a pressure house on my rims and tyres only but there's no real benefit to it and keeping the high pressure spray away from the bearings means it's more hassle than it's worth.

comment Could I be pumping up my tyres the wrong way?
To pump up road bike tyres with my double barrel foot pump i actually have to push on the garage ceiling. The track pump is hard work but much more sensible. The combination of static friction and the overpressure needed to actually get site into the tyre means you'll need quite a bit more down force than just pressure * pump cross section.

comment Bike computer with backlight
I've found that with a lot of the cheap stuff things like backlights and battery status lights can be excessively bright, almost dazzling - so be careful choosing.

comment Is standing up and pedaling on multi-gear bicycles a bad idea
Offroad #2 applies to commuting given the state of the cycling infrastructure and roads round here and many other places -- the traction aspect is really quite important at this time of year (wet leaves, muck washed onto the road).

comment Removing spray paint to reveal frame's factory paint job
In which case you may as well try progressively harsher solvents on the off chance. White spirit, acetone, cellulose thinners then paint stripper (for example). nothing to lose.

comment Centermounted kickstand on touring cyclocross
It's not a nice centre stand like you've got, but there are some really solid kickstands that attach to the left chainstay by clamps - on steel or alloy that may be an option.

comment What bike/helmet camera resolution is needed in order to read licence plates?
A major issue will be that most rugged cameras have wide angle lenses - and that's normally what you'd want for a surveillance camera. Looking for a narrower field of view would help as that would mean more pixels per number plate at a given distance -- but a smaller chance of seeing the plate at all.

comment Is it safe to mount fender stays and disc brakes on the same bolt?
Another workaround may be to screw in a stud (threaded rod) then the brake, then a nut, done up tight, then the fender mount, then another nut, preferably a dome nut to avoid sharp edges on the stud which would have to be cut to the right length.

comment Croozer bike trailer optimalisation for less tire detoriation
It's also possible that the extra load (implied by longer trips) means more scrubbing. It would seem to be worth trying to get to the bottom of the play in the mechanism - perhaps some close-ups of that would help.

comment Biking in the winter more difficult?
If (as suggested below) the grease has thickened up due to the cold, all the extra effort you're putting in (which has to go somewhere) should end up thawing out the grease (you could be talking in the range of 100 W split between all the bearings). Also with the bike starting from a garage the grease wouldn't be that cold. I've not gone that cold on my hybrid but have taken it out for an hour a few degrees below freezing without any noticeable penalty. If it's not been ridden for a while, does everything spin freely in the (relative) warm? Is the chain rusty or stiff?

comment How to build surge brakes on bike trailer?
On the other hand emergency-stopping a 150lb trailer without a brake on it could be interesting. You can assume you're not going in a perfectly straight line, so it will try to overtake you - hopefully on the hitch side and therefore without the towing arm hitting the back wheel. So it might be nice to have in a rare set of circumstances. Which makes it hard to test. Given the recent discussion about brake lights I wonder about an electrically-operated trailer brake. A few C-cells and a solenoid wouldn't add much weight. The switch would need to work in the same movement as normal braking.

comment Why are brake lights not common?
With a 20mph zone now covering most of a hilly city around here the situation changes: Bikes and cars are going at roughly the same speed (though car drivers often don't realise this before they act) and freewheeling downhill means the pedals aren't going up and down.
