Hi,
Yesterday I broke the front bumper on my Miyata seat. It cracked along the
perimeter of the area that bolts to the seat.
These things seem impossible to get (although unicycle.com said they’d be
stocking them whenever Miyata can send them some). Does anyone have experience
gluing cracks in their Miyata seat bumper? If so, what glue did you use and how
well did it work? Any other ideas?
Thanks,
Kris.

I’m surprised at you. A guy who takes such good care of his equipment breaking
bumpers? What sad times these are. 
It saddens me more to say that I’m not aware of a glue that will do anything
useful toward fixing those things. You might be able to repair a rear bumper, at
least cosmetically, but I don’t think it would be able to take much pounding
after that. But the front bumper/handle gets an awful lot of stress.
I wish I had some of that glue they use to stick those reflectors onto the road.
You know, the ones that mark the lanes? That’s some form of hot glue that can
take being run over by 1,000,000 trucks. It’s gotta be good glue. But I still
don’t think you’d be able to stress the joint by using the handle. You need a
new bumper.
It’s annoying that a factory in Japan is cranking out tons of those things, but
we can’t get any shipped over here; even though there is demand. The demand
isn’t very big, but it’s equal to nearly any other spare parts situation.
One possibility is to pester Matt Hyer for more parts, especially seats and
bumpers. Matt is the guy at Miyata’s US warehouse. He doesn’t have a tremendous
amount of control over what gets shipped his way, but he can at least
communicate with the folks in Japan.
For Kris, I wouldn’t mention that you’re in Canada because that might be a
different distributor. But if you buy your stuff from UnicycleSource, you are a
US customer. Call Matt at Miyata USA: 1-800-323-8553.
Remember, if you plan to buy a unicycle, get it from UnicycleSource
(1-800-UNICYCLE, www.unicycle.com), where you can talk to an expert who knows
what unicyclists need!
Meanwhile, we need seats. Different people have different preferences, but many
prefer the Miyata design. That’s great, but it’s always such a pain to get them,
especially ones that aren’t seasick-green. We need somebody to start
manufacturing heavy duty seats and posts for us adults. Seats with strong
bumpers, good padding, and available add-ons like handlebars (hand supports),
computer mounts, brake mounts, etc.

Re: gluing uni bumpers
Kris,
You beast!
I am afraid that you will need another bumper. I believe the bumper is made from
nylon and there is no effective adhesive for bonding this together. The area
around the holes is the weak area so it is bound to fail at some point.
While we are on seats… have you noticed that Unicycle Source are now
stocking carbon fibre replacement seat bases. These should help with the life
of the other seat components as it will not flex like a standard seat base.
The seat does not require the standard reinforcing on a Miyata seat so it
lighter as well.
Cheers
Roger

Re: gluing uni bumpers
If it’s really nylon, then couldn’t it be melted back together? As I know from
years of climbing with nylon ropes and slings, nylon melts easily and can be
used as glue. No idea if it would really work on your bumper, but it sounds like
you have nothing to lose in trying.

I’ve tried it! I was able to melt it back together and it would seal together,
but it was very weak and didn’t last more than a week after that. This was for
an old style miyata seat which is impossible to even find a manufacturer
replacement anymore since they are no longer made, so I decided to make my own
out of composites, a combination of Carbon fiber and Kevlar. So far it’s lasted
me about half a year and it still looks like it’s in good shape.
