Now that I know my folder is here to stay, I'm thinking of essential upgrades like: a bike mirror, lights, pedals & a basket.

However, it seems like I have to consider foldability whenever I add something like:

Bike Mirror

Which types should I consider that won't interfere with the fold, if any?

Lights

To blinky or not to blinky?...That is the question. Whether 'tis nobler in the mind to suffer the bings and dings of riding in the dark or to take arms against a sea of cars
by having front and back lights... and in so doing...avoid them. Yep, you guess it. It's another question except it has to do with either getting a static light or blinking one.

Normally I don't go riding at night but as the days get shorter, I can see riding home a little after dusk from work.

Pedals

Pedals, pedals everywhere but few will fit my bike.

I am thinking of the MKS FD-6 to replace the clunky suntour ones I now have. Not sure if the MKS FD-6 will be just as thick as the ones I have now. Yes, the few nano cm I don't have to adjust to, via the seat height, does matter.

Does anyone know for certain then if the MKS FD-6 is thinner in profile than the suntour pedals that came with the bike? I can't find measurements anywhere on the web on this.

Basket

Thinking of getting the seat post or frame adapter to put a klixfix wire basket in the back or front. However, something tells me that the seatpost or frame adapter would interfere with the fold. Am I correct on that?

Not crazy about handlebar baskets. I've got too much crap and I find them a little too distracting.

Sorry for all the questions. If the bike was just a regular bike, I wouldn't have to ask the above. However, since the key feature of the bike is the fold, I'm trying to keep this feature intact but not at the cost of overall safety (bike mirror) or basic convenience (basket).
