How to make a suicide hub safe?
Hey i am planning on making a suicide hub, because i do not have enough money to buy a real track hub. So is there a way to make a safe suicide hub. I have heard of welding/brazing but i want something simpler.

Best thing is to rotafixa the cog on the hub and add a bottom bracket lockring - but most importantly, use a rear brake for braking instead of backpedaling. This is, in a nutshell, what Sheldon Brown recommends.

If you use brakes, you're fine. If you don't use brakes, rotafix the rear cog on and possibly use some JB Weld. If you're planning on going down a lot of hills, use brakes.

The title is contradicting

You gonna eat that?
I actually have the parts to do a suicide hub on an old Schwinn when I get around to it. I picked up the parts for next to nothing at a swap meet. I figure it will be a learning experience. When I see how it goes together I will JB Weld it but also I will see if there is any way to put a set screw in it. I'm a mechanical engineer; I never depend on adhesives for critical joints.

No. I haven't looked at it yet. I'm thinking of a teeny little set screw... the smallest I can get... and maybe drilling through the threads between the cog and hub (parallel to the axle), then just screwing the screw in without tapping, and just locktiting in place. I see the wheel as pretty much disposable; I got the whole bike for $10. If I decide I like FG then I'll get a proper wheel with a track hub. This is kind of a try-before-you-buy/learning experience project.

The point of the suicide hub is that you don't have to do it yourself. Instead of cutting yourself with a razor "across the street" or "down the street", you can just let your cog spin off while skidding down a hill. I swear getting hit by a semi is less painful than blood letting, and looks wicked cool.
Use a brake.

Maybe put a bottom bracket lockring over the cog? It probably won't help much since they thread on in the same direction.

Suicide up is only OK SS, nogo on FG.
Seriously, if you really want to trim it up, go SS until you can afford a new hub.

Aww... will the BS flood ever stop? Why don't you people actually think a bit with your heads instead of going with the herd and parroting each other?

Despite the silly name, this is no more dangerous than using a freewheel, as long as you keep front and rear hand brakes installed.

And if you ask "Who the heck is Sheldon Brown anyway?" - well, he was only the greatest advocate for fixed gear riding ever to walk the earth (and pedal thereon).

A so-called "suicide hub" can be perfectly safe for street riding. The real danger comes from not using brakes regardless of whether "suicide hubs" OR track hubs are fitted.

My buddy was running suicide style without a lockring for a while and somehow he didn't die, then i stomped on his cranks backwards to show him what would happen. After seeing the cog backing itself off, he wanted to fix it. A bottom bracket lockring and some red loctite got it working fine, no problems since then.

The OP has not commented on using brakes, I wish he would. Again, if you didn't hear it, it is only suicide if you run brakeless.
