  1. Hi,
    I installed a little Pedro's expandable under-the-seat bag, but I had
    to remove the red reflector. After I readjusted the seat height, (I'm
    a shortie), there was no room to re-install the red reflector on the
    seat stem.

    Is there a red reflector available on the market that I can use by
    attaching it to the back of aseat bag? Can someone suggest an
    alternative to the seat stem reflector? I'm stumped...I just hate to
    give up that little bag full of useful goodies.

    Thanks, as usual, for the great help I've been getting, Mikie

    Hi, forget the relector and buy a small rear light. One with mounting
    options.

    See what Sheldon says about reflectors:

    can you mount is on one of the seat stays instead?

    In the past, I've installed reflectors on bags. Any reflector with a
    screw mount can be used that way, by poking (or hot melting) a hole
    through the bag fabric. It's best if the bag has adequate stiffness to
    keep the reflector pointed straight back. Use a stiffener or washer
    cut from milk jug plastic, if necessary.

    On one of my bikes, I have an LED blinky with a reflector built into
    the lens clipped to the seat bag. The bag has a two-sided zipper, so I
    can center the zipper opening straight behind me. The blinky has no
    screw thread, but it clips nicely into that opening.

    An optical feature that may not be obvious, is that retro-reflectors,
    as most such devices for vehicles are, use trihedral reflectors,
    commonly called "cube corners", (three plane surfaces oriented at 90
    degrees to each other) that return incident light back to the source,
    as do glass beads in Scotchlite(R). Therefore, such reflectors must
    only be facing to the rear sufficiently to expose a reasonably large
    projected area to incident light.

    From this, I take it, the reflector is not exactly facing to the rear
    and of course it doesn't need to.

    Get some 3M reflective tape at an auto-parts store. Wrap it around your
    seatpost, seat-stays, and anywhere else visible. Rims is a good spot,
    as well as cranks and head-tube and fork blades. More effective than a
    flat reflector IMO because it can be seen from many different angles.

    I would just get a simple battery powered LED tailight to put on the back of
    the bag.
    In blinking mode most all the LED tailights almost run forever.
    Although there are like hundreds of different types to choose from;
    an amazingly good cheap one is the BELL brand ultra bright 5 LED tailight
    that you can get from Walmart of all places.
    The LED tailight also has some reflectors in the rear lense as well. I
    typically only use the blinking mode.
    All the other modes aren't of interest to me, but the single rotating slow
    blink mode might be good for group rides in twilight conditions as it
    doesn't irritate those who are behind you so much. They have a headlight
    that isn't bad either, I like the white LED blink mode on it too as it also
    lasts forver in blink mode too. The little halogen light works Ok though,
    but not super bright.
    Yes there are better lights that one can get, but these work pretty good
    though and are cheap too.

    Well, they have their limits regarding angle of incidence. I've ridden
    behind cylcists with LEDs and/or tri-panel reflectors pinned to
    backpacks or floppy bags. The cube corners pointed way off-axis, and
    the devices were useless.

    It's actually very close - I just double checked. The reflector axis
    was within about a degree of being parallel with the ground (IOW, pitch
    angle). Yaw angle (side to side) was biased about three degrees
    leftward.

    This bag and blinky combination behaves that nicely with no special
    help. Again, if necessary, I'd have added stiffeners to keep things
    focused.

    Which country?

    I'm in the USA and took mine off. Until recently I had a nice compact
    blinky Sigma Sport rear light. The bracket just broke and I have yet
    to address it.

    I don't ride at night, but if I do, my other bike has two tail lights,
    front light, and wheel reflectors.

    This is true, and it disturbs me to see loops for mounting blinkies on all
    kinds of bags and clothing. This gives a false sense of security and
    encourages misuse. I see a lot of riders with blinkies clipped to their
    backpacks [censored]-nilly, and they're barely visible.

    Fortunately my seat bag, a Trans-it model from Performance, has a nice
    tight loop to hold my blinkie at the right angle. My blinkie is a Cateye
    model that's also rated (CPSC) as a reflector. But when it's dark enough
    for the reflector to be useful I have the blinkie on anyway. So while
    reflectors are a good idea, you should also just buy a good blinkie and
    use it.

    Scotchlite tape is very effective. The heels of your shoes, the rear
    faces of your cranks when they're pointing up, and the insides of your
    rims are good places to put it.

    DOT-type reflectors are great, but again, you need a place to mount them
    properly.

  13. If it causes problems mounting a reflector, it will also cause problems
    mounting a blinkie light.

    You may be able to sew a strap to the back of the bag, then mount a
    blinkie there. You may be able to mount it to the seat tube. You may
    be able to buy a clamp for mounting a rack to a seat stay, then get a
    reflecor or blinkie to attach to that.

    I'd say the red reflector is a good idea even by day, light just for the

    I designed my own blinky and haven't settled on where to mount it. Most
    probably it will *not* wind up in place of a reflector that's clamped to a seat
    stay; I don't want it so close to the bottom of the HUGE anorak (a hand-me-down)
    that I wear in bad weather (too easy for anorak to cover the reflector when I'm
    sitting upright). I don't like seat post mounted or seat mounted
    lights/reflectors for the same reason. An additional reason is that one of my
    bikes has a rear rack, which is often *very* loaded, the load obscuring from
    rear view everything above top of rack and below my hips. So I'm leaning
    strongly toward mounting reflectors and blinky on the rear of the rack.

    With a nod to the other posters who emphasized the hazard posed by improper
    mounting angle, two nights ago I saw a rider with a blinky attached high on his
    back zip past my house. He was in the drops, so blinky pointed almost straight
    up. I wondered if I would have seen the blinky if it hadn't been foggy and
    rainy (some reflections) at the time.

    Out of curiosity - are LED tail lights legal there, or (as was true in
    Britain) do the laws still specify old-technology filament lamps?

    And a related question: When a person's bike has practically adequate
    but technically illegal equipment, how do European authorities react?

    In the US, almost all bike regulations are totally ignored. Only
    terroristic-sounding frame decals are given any attention. What's it
    like over there?

    What about one of those out-riggers that puts the reflector out to the
    left side to help claim some road space? A day-glo vest w/ reflective
    stripes is always pertty good too.

    I use a blinker that clips to my waistband. Reflectors really aren't
    enough to do the job IMO. On my old seat bag, there was a short strap
    across the back that allowed clipping a blinker directly to the bag.
    You could also poke a hole in the fabric and mount the reflector to
    the bag.

    There are also reflector brackets that mount to the seat stays, but
    for visibility from both sides to be assured, you'd need two of them.

  19. Additional issues:

    Low-end Wal-Mart bikes of my experience tend to have lousy seats;
    don't be surprised if you find that the seat on this one either
    refuses to stay securely clamped (tilting when you hit a bump) or just
    can't be ridden comfortably.

    The lack of a hand brake for the front means that you're going to have
    a much longer stopping distance than you would if a front brake was
    present.

    Before you ride the bike, look closely at the position of the valve
    stems in the wheels. If the stem is angled or seems jammed to one
    side of the hole in the rim, deflate the tire, reposition the tire and
    tube as needed to get the stem centered and straight, and reinflate.

    Remember, tires lose air slowly no matter what you do; get a tire pump
    unless you have a source of compressed air very close by. Never ride
    on a flat unless you have a fondness for replacing things that could
    have been reused.
