comment Do pedal-driven bicycles exist that can handle highway commutes?
In theory one could build a flywheel-assisted unit that would let you "store up" energy by pedaling for several minutes before you began moving. At best you'd need to pedal about 5 minutes standing still for each minute of highway speeds you achieved. Beyond that there are are beginning to appear various solar powered cycles that can provide some assistance, but they would not permit sustained highway speeds.

comment Would rim brakes help a slightly bent rim?
It means something has "given" -- either the spokes have stretched or the rim has bent or some such. In general, you attempt to correct the problem by adjusting the spokes, though there's a limit to how well that can work.

comment Rear cassette 'ticking' forward, making chain catch, what is the problem and how do I solve it?
The ratchet mechanism in the rear hub is probably sticking. My understanding is that it's best to replace the "freehub" assembly than to try to rebuild it, though rebuilding is not impossible if you're so inclined.

comment Would rim brakes help a slightly bent rim?
No. But it's possible that the wheel realigned itself slightly as the stresses in the spokes equalized. Also, of course, the brakes will wear faster when the wheel is bent and so the gap between wheel and pad will grow.

comment Best kind of bicycle for lower back issues?
You might be advised to get your back checked out. Probably a doc first, and then a physical therapist, to learn some back stretches and exercises. As we get older our muscles get weaker (and lazier) and it takes more effort to keep them properly toned.

comment Tyre suddenly gets tilted
One should make sure the wheel is pulled all the way rearward before centering and tightening.

comment average cycling speed 12km/h
Yes, it's a bit tedious to do so, but not rocket science: Count the number of teeth on the largest front cog and the smallest rear cog. Either report those numbers here or plug them in to a gear ratio calculator.

comment How accurate is the 'calories burned' figure on my GPS device?
It might be correct within a factor of two, in not-too-extreme cases.

Well, you can time yourself for a KM or two, if there is a convenient stretch of road with KM markers. Or purchase an inexpensive cyclometer (though the quality of those has really gone downhill for the past 10 years or so).

Well, you'll probably need to replace the chain, or at least a few links. And, unfortunately, having the pin break on a chain tool (especially a cheap one) is not unusual.

comment average cycling speed 12km/h
It is slow, but everyone moves at their own pace. Select your gear based on the effort required to maintain a decent cadence (70-80 is good). If you feel you can put out more effort (over the distance you're doing) then use a higher gear. (Your highest gear would be the largest front sprocket and the smallest rear sprocket.) If the highest gear is not satisfactory, you can probably get the rear cluster changed for one with smaller cogs.

comment Road Bike Tire Throwing Rocks
Are you saying the stones are thrown from the back, or do they "squirt" out the sides? I have stones "squirt" on occasion but they rarely travel more than a couple of feet. And (nearly bald) road tires won't throw stones out the back.

comment Is my six-year old touring bike worth repairing?
A decent touring bike, at 6 years old, is practically brand new, unless you've really abused it.

comment Bicycle saddles
The theory is that the hole removes pressure from some important nerves and blood vessels in the nether region, and also allows a bit more ventilation.

comment How difficult is the switch from flat to drop bar?
Difficult??? When I ride a bike with flat bars it feels very unstable! I can't wait to get back to my tourer.

comment What's wrong with my tire?
Yep, no reason for it to not simply be bad luck. Unless you're habitually running your tires underinflated and hitting lots of potholes and curbs, in which case don't do that.

comment bike keyhole broken
You can haul it to a locksmith, or you can use a bolt cutter or angle grinder as stated. We can't advise you further without knowing what kind of lock it is -- cable, chain, U-bolt?

comment Cuyuna Lakes, MN Camping?
(That area of the state is filthy with resorts and campgrounds. The Cuyuna County State Recreation Area has a campground, and there are maybe 2 dozen private campgrounds. But most are not really set up for tent camping, so you probably need to ask someone in the area.)

comment Corroded brake levers
(There is a slight chance that what you see is staining of the anodized layer, but I don't know of a way to remove the stains without damaging the surface.)
