comment 9x4 spoke pattern
While the spoke nipple placement seems the same in those two examples, the lacing pattern seems a bit different.

comment Air Pressure on wheels
Assuming x is in bar or PSI, as those are the common units used, then, having an x value of 90 would mean that the front tire is at 89 PSI, and the rear tire is at 92 PSI. You might as well just call it x, as most pumps don't even measure that accurately, as 2 psi is not going to make a huge difference. If we are talking bar, then then we have an x value of 6.2 bar (90 psi) and we have the front tire at 5.2 bar and a rear tire at 8.2 bar, which is too much of a difference to be reasonable. Also, I can't seem to get a value for x that makes sense value no matter which units I use for weight.

comment Air Pressure on wheels
Also, if the pressure is too high, then the tire will be unable to absorb irregularities in the riding surface. In a velodrome, pressures around 180 psi are not uncommon, but on the road this is unheard of because it would be uncomfortable, but would also require the bicycle to be lifted over the bumps, causing quite a bit more lost energy than simply having the tire deform around small bumps.

comment What kind of bicycles do they ride in the Tour de France?
There's a rule in the UCI that parts must actually be commercially available, so by definition, they have to be riding stuff that's available in bike shops. However, you'll only see them riding the top end stuff, and if you were to buy the same bike from the shop, it would probably cost you $10,000+. I personally think the only reason these bikes are sold in shops is because it's required the pro parts be available for sale. The bikes they ride in the TdF are way more advanced than most people would get from a shop. You won't see the pro's using Shimano 105, even though it's quite good.

comment 3 flats in 650 miles (1030 km) on hybrid bike. Tire pressure wrong?
Could just be cheap tires. Tires is one of the things most often skimped on, even when purchasing a high end bike. Most people buying a hybrid would not even stop to think about asking what kind of tires were on the bike. That isn't to insinuate anything negative about people who buy hybrids, I've bought one before myself. However, I think that many people who put any serious mileage on a bike will come to the conclusion that a road/touring/cyclocross bike is a much better option as the drop handle bars allow the ride to be a lot more comfortable due to enabling more hand positions.

comment Winter deraillers
If you don't have horizontal or semi-horizontal dropouts, you may still need a chain tensioner with an IGH, but they are much more simple, and some have no moving parts and therefore have fewer problems.

comment Will 40km E-Bike trip in Texel Island(Holland) be hard for untrained people?
My only real concern would be how well they knew how to ride a bike. Sure, quite a few people learn how to ride bikes as kids, but many of them stop before they've even had a chance to ride with gears. If they haven't biked in a long time, then riding an e-bike might actually be more difficult than riding a plain old pedal bike. Depending on traffic, road condition, and other factors, some people might actually have trouble handling the bike itself.

I meant moderately fit as in not majorly overweight or other physical conditions that would lead to problems of increased activity. I recommend that you see if you can rent some e-bikes at home (or just a single one to share for the day) to get a feel of what it's like if you are unsure.

comment Will 40km E-Bike trip in Texel Island(Holland) be hard for untrained people?
As long as the E-bikes have a range of 40 km on the terrain you are traveling (range will vary depending on hills), you should be fine. 40 km would be quite a short ride, and even at a moderate pace of 20km/h (most e-bikes max out around 28 km/h depending on jurisdiction) it would only be 2 hours of actual cycling. As long as your group is in moderately good physical condition, it should not be hard.

comment Cycling Computers for seamlessly uploading to Strava?
I don't own one, but most of the time for stuff like this if you just don't have Garmin Connect installed, or make sure the background process isn't running. From the sounds of it, Garmin Connect will come up as soon as you plug it in.

comment Can I use a 1“ stem on a 1 & 1/8” steer tube?
In that case, they also make adjustable angle threadless stems. I had one before, and I didn't really like it, as it had some movement in it. Maybe mine wasn't good quality. Anyway, I understand why you'd want to use a quill stem in this situation. Makes adjusting the height pretty easy.

comment Cycling Computers for seamlessly uploading to Strava?
Funny how the cycling specific units make it more complicated to upload you rides. I have an Oregon 450, and all I have to do is plug it in, it shows up on my computer as a USB drive, I go to Strava and upload the file. Couldn't really be any simpler.

comment Is 11- 34 rear cassette necessary?
The other option, which would end up being more expensive, would be to switch to a triple chainring in the front. This would require changing the shifter as well. This would give you more range, while allowing you to keep the spacing between the cogs the same. I had an 11-32 before and I found the difference between successive gears was too big and I was always in too high or too low a gear to be really efficient. I already had a triple, and went with a 12-23 as I was able to find the right gear a lot easier.

If you're using a quill stem, you might want to look into getting a quill stem adaptor. This would allow you to use a more modern stem which are available in many more lengths and angles than traditional quill stems.

comment Wheel size for heavier rider, larger vs smaller
@DanielRHicks If your only concern was a strong wheel and whether or not you could ride over bumpy surfaces, then a small metal cylinder like the hub would be actually quite appropriate.

comment Can you tell me what the name of this bike is?
It looks like yours has a white pie plate/spoke guard on the back, whereas in the question it looks metallic. Also, the crankset on yours is hollow to look like a flower, where as is the question they look more like the Sting-Ray, although it's hard to tell. Also, I don't think boys rode purple bikes in the 70's, although I could be wrong, so I would have to guess the picture in the original is somewhat color accurate, although now that you mention it, you really have me thinking it might have been purple.

comment Can you tell me what the name of this bike is?
That looks a lot more similar than my answer. Basically identical except for the colors. One difference though, is the bar holding up the back of the seat goes quite a bit higher than the edge of the seat, whereas in the question the bar basically stops just above the seat, but that could just be a girls model vs. boys model difference.

comment Is This Bike Worth 7K
Yeah, you really have to think about something like this as a business investment. Coffee is very high markup. You can make a cup of coffee for about 20 cents, and then sell it for $2. So you'd only have to sell about 4000 cups of coffee to make your money back. That's 40 cups a day (which isn't even a lot of coffee to sell) over 100 days. I'm not sure what the franchise is like, or how much their cost on coffee actually works out to, but it seems like a relatively cheap way to start a business.

comment Can you tell me what the name of this bike is?
@DanielRHicks Yeah, I couldn't find a model that matched exactly. The basic design is a Sting-Ray, and looking for that would be the best bet for getting something similar in the current market. I looked at a lot of pictures on Google last night, mostly because these are such nice bikes to look at, and I didn't see anything that matched the bike in the question, especially in relation to where the chainstays/curved tubes meet so close to the headset tube. The drive train, seat, rear fender and handlebars are pretty much identical to the pictures I've seen.

comment Is it possible to add speeds to single-speed bike?
27 speeds is a lot of speeds. Most bikes with 27 speeds don't really have 27 different speeds, as there are a lot of combinations which are basically the same as other combinations. Even pro racers only have 22 speeds, again with some overlap. 7 or 8 speeds provides plenty of range.
