The Best Safety Flags for Tricycles: Be Seen Over Parked Cars

This is the flag most trike riders end up with, and the reason is the sectional pole. It comes in five 13.78 inch fiberglass lengths joined by four connecting tubes, so you pick the height rather than accept one. The maker suggests four or five sections for adults and two for a wheelchair, which is a useful range: on a low recumbent, three or four sections lift the flag well above the seat without the pole whipping in a crosswind.

The flag itself is orange polyester that is printed, waterproof and easy to wipe clean. Fiberglass is the right material for a flag on a trike because it bends in a gust and springs back, where a rigid pole would stress the mount. Compared with the second Uelfbaby, it is the same family of product with a long record of owners; the choice between them is less about the pole than about the bracket and the age of the design.

It suits a rider who wants a proven flag and the freedom to tune the height. The caveat is that every extra section adds leverage on the mount, so build only as tall as your route needs and check that the bracket is tight after the first few rides.

This one looks and behaves like the first Uelfbaby, and the two are close enough that the difference is mostly in the mounting. It attaches at the rear axle, which puts the pole at the back of the trike, centered and behind the basket, where a following driver sees it first. It is also pitched at kids, older riders, trailers and wheelchairs, and the same five-piece fiberglass pole gets you to six feet.

Compared with the first Uelfbaby, this one has the shorter owner record but the clearer mount; compared with the MAQIHAN, it goes higher, by half a foot. On a trike, the rear axle sits in a different place from a bicycle's, with a wider axle and often a differential housing, so look at where the bracket would sit. Make sure it clears the axle nut, the basket and the rear tires before you commit to it.

It suits a rider who wants the flag at the back and the height of a full pole. The honest caveat is that a bracket designed for a bicycle dropout may not fit a trike's wide axle at all, so confirm the clamp can reach before you order, or plan to mount the pole to a rack or basket frame instead.

The MAQIHAN is half a foot shorter at its full build, with five 11.8 inch fiberglass sections and four connecting tubes, and its flag is orange on both sides. That matters on a trike more than on a bicycle, because a following driver sees one face and a driver coming the other way sees the other, and a flag printed on only one side shows white fabric on the back. The flag is waterproof PVC, which wipes clean.

It comes with a bracket for the rear axle, so the same mounting caution as the second Uelfbaby applies: check that a trike's axle is within reach of the clamp. Compared with the Uelfbaby pair it is shorter, which is an advantage in low branches and garage doors and a disadvantage when you need to clear a parked van. Its owner record is smaller than either of them.

It suits a rider who wants a good-sized flag without the full six feet, such as a recumbent or a rider who passes under trees. The caveat is the thinner owner record: a new design can show a weak point in the connecting tubes or the flag stitching after a season, so check both when the weather turns.

The RAXCONN is the only flag here with a pole that telescopes, running from 11 inches to 63 inches, or about 5.3 feet, in a smooth slide. That removes the connecting tubes that can work loose on a sectional pole and lets you drop it to a short height for a garage or a narrow door. The flag is 25 by 35 cm with a 5 by 18 cm reflective strip, so headlights at dusk have something to bounce off, which an orange flag alone does not give.

It mounts with a pole holder that clamps to a rail, with a 3.5 cm wide clamp that grips thick round tubes. That is a real advantage on a trike, where the rear basket frame, a rack tube or a seat stay is often a better mounting point than the axle. Compared with the Uelfbaby and MAQIHAN, it costs more and has an alloy pole instead of flexible fiberglass, which is stiffer and bends less in a gust. Its owner record is the smallest in the group.

It suits a rider who wants a reflective strip and a pole that stows short, and who has a round tube to clamp to. The caveat is that a stiff alloy pole puts more force on the mount in a crosswind, so tighten the clamp well and check it often.

The second RAXCONN is a sectional pole you can adjust from 1.5 feet to 6 feet, with a flag in a novelty dinosaur-tail shape, reflective stripes and a string of lights. The flag is polyester with a fiberglass pole, and it attaches at the rear axle like the Uelfbaby. The reflective stripes give the same dusk benefit as the telescopic RAXCONN, and the lights add a point of color near the top of the pole.

On a trike, a flag with its own reflective and lit elements is more useful than a plain one, but it still does not replace lights on the trike itself. A string of lights on a pole is a small glow, not a headlight, and it is not a substitute for a proper rear light. Compared with the telescopic RAXCONN, this one uses a flexible fiberglass pole and a rear-axle mount rather than a clamp, and its owner record is a little larger.

It suits a rider who wants reflectivity and a taller flag on a rear-axle mount. The caveat is the same as for every axle mount: check that the bracket reaches a trike's wide axle, and look at how the lights are powered and how often you will need to replace the cells.
