Liquid nail question, ss to fixed

Hello everybody, recently I have seen a lot a kids around my campus with fixed gears. So I found my old BMX bike that I would like to convert, so I could just try out riding fixe. Also I have been reading a bunch of threads where people used lock tight on their cogs to make them fixed.

My questions are

1. Would I be able to achieve the same results if I use liquid nail instead of lock tight on the cog?

2. also how would I have to take apart the freewheel to apply the liquid nail/lock tight?

3. and last I want to know what would happen if I back pedal with liquid nail/lock tight on the cog? I don't understand what happens if I would back pedal.

Also thanks in advance for answering my questions

Sal

JB welding a freewheel is called a suicide hub for a very good reason. If you do try it, don't remove your brakes!

Back pedaling with a fixed gear will make the bike move backwards assuming you're standing still. Applying back pressure while rolling will make you slow down.

It sounds like you're thinking that people are gluing their freewheels into fixed cogs...this is not the case. Some people will put a track cog onto a hub with freewheel threads, in which case some loctite would be a good idea. Trying to put glue into the mechanism of a freewheel is not going to work.

A suicide works like this:

BMX freewheels 16t and bigger are ISO thread, as are track cogs and old English bottom bracket lockrings.

The freewheel is removed, Loctite is applied to the threads, and the cog and lockring are screwed on.

This is not as secure as the cog/lockring combo on a track hub because these have left hand threads for the lockring. When you backpedal on a suicide hub, eventually the twisting is going to move the cog, and that will loosen the lockring. On the track hub, this rubbing force is in the direction that tightens the lockring.

THIS!

what happens if you backpedal? in the setup you are suggesting you probably lose some teeth.

It's not uncommon for some flatland BMX riders to use a fixed hub.

I've got this setup on the flip side of a Bianchi Pista, the rear hub of which is threaded for fixed track cog and lockring on one side (with 16T track cog) and freewheel on the other side. The freewheel side now has an 18T track cog, BB lockring and copious quantities of Loctite for street use. Also put a front brake on for street use as I fully realize there's a possibility it could come loose with too much back pedal force, and I shouldn't be doing skidz with it.

When I rode bmx my flatland rig was fixed geared 20/37. Made it really easy to pop the front end up.

A suicide hub is a normal threaded road hub with track cog and bottom bracket lockring. This is not that... I've welded (not JB) up a crappy bmx freewheel out of boredom while stuck in Alaska for a few months because there was an abandoned bmx bike left in the garage. It worked, but I wouldn't trust it for anything other than tooling around.

I would recommend using Tub & Tile caulk rather than Liquid Nails because it will resist mold and mildew.
