Hey thanks for looking and for the comments all! I must say that I have been inspired by the mods presented in this forum and that it is only fair that I share my experience with my Brommie. Now to answer a few questions.
Somna, I see what you mean about the bent S-stem assembly and how it would interfere with taller bags. With that in mind, I think my present setup will allow the use of the grocery basket. I am pretty excited about getting it as I plan to mod a few bags and baskets so that they can be secured to the frame that comes with the folding grocery basket. I think a small black plastic milk crate will look good on the bike. Thanks for the clamshell tip on another thread, by the way.
About the rollers and heels - I did have some problems with heel strike at first, but I adjusted my pedal stroke to clear the rollers. This was a long time ago, it has been months since I had my last heel strike. For people that can't seem to get rid of heel strike, there are pedal extenders available that increase the Q factor of the pedals. I have several inline skate wheels of varying diameters and I experimented with different sizes and combinations. I found that I prefer the larger wheels as they can negotiate sidewalk cracks and uneven pavements better. They really make subway forays easier as all the bike needs is a little nudge. Once in the train though you have to wedge the bike between your legs or a wall so that it doesn't roll around. An interesting fact about the 100mm Razor scooter wheels is that they are actually around 2mm thinner than a regular inline skate wheel, so that helps a bit. On a related topic, all of my relatives know that I am on the hunt for inline skate wheels so they save their old skates for me instead of throwing them out
I am very happy with my handlebar choice. It allows me to get into a slightly more aerodynamic position that I am used to. At the same time, it gives me a wider grip that gives me better steering control and breathing. I searched the internet for the tallest mountain bike riser bar that I could get and I wound up with this Azonic WF Riser. It is available at 1.5", 2", and 2.5" heights and I opted to get the tallest one. The stock M handlebar is 5 inches tall and gave me an upright ride that was Ok with me but I felt that I would be better off with lower handlebars. I am 5'10" by the way and my preferred road bike size is 56 c to c.
Shiny, thanks for the link on that gadget, that looks very interesting. Another future mod that I plan to do is to install swiveling casters so that I can maneuver my folded bike like a shopping cart. Now that would be interesting
By the way, I have noticed that my folded Brompton when pushed travels in a slight arc rather than in a straight line. Do your bikes do the same?
