A single 3/8 inch stainless steel rod can be welded as a brace on
Miyata seat posts to stiffen and support the front of the steel base
plate where the seat is mounted. This may make Miyata seats with a
front handle more effective. However, strengthening the seat post
base plate may cause the seat itself to take more stress. On the
other hand, the Miyata seats seem to be less prone to failure than
(unbraced) Miyata seat base plates.
Two 5/16 inch stainless steel rod braces can provide support closer to
the front end of the seat base plate and to each of the two front
corners of the base plate, resulting in an even stiffer base plate (at
the front end).
Stainless steel will match the rest of the seat post in appearance and
texture. More importantly, stainless steel is extremely resistant to
The front seat plate braces may also be effective for other brands of
unicycles. A stiff front seat plate is a positive attribute in a
unicycle, even one without a handle built into the seat. Both
artistic unicycling and long distance coasting are easier with a
stiffer seat plate and seat. It may be an advantage in MUNI as well.
Finally, a separate steel handle below the seat braced to the seat
post as mentioned before (done well) is clearly superior to the
alternative I mentioned. However, my alternative also strengthens the
front of the seat plate and consequently the seat as well.
Perhaps, a seat plate brace can be combined with a separate steel
The separate handle shouldn't extend more than a few inches in front
of the seat. However, it should be far enough forward so there is
plenty of room between the seat and handle for one's hands to easily
move between without even the remotest possibility of getting caught
