How to Build a Fixed Gear Bicycle

Fixed gear bikes normally only have one gear and cannot coast. There is no freewheel mechanism that allows the wheels to move independently. The pedal on a fixed gear bike is always moving while the wheels are moving. They are durable, easily maintained, operate easily and are quiet to ride. A fixed gear bike has become a novelty.

Difficulty: Moderately Challenging

Instructions

1. Find a bicycle frame in a style that you like. Strip all the excess parts off the frame. Clean off any rust and paint the frame in a color that pleases you.

2. Decide if you want to keep the rear wheel or buy a new one and start afresh.

3. Connect the cog directly to the rim of the wheel. Remember not to forget the lock ring.

4. Remember there are two types of threading on the fixed gear hub. One is closest to the spokes and the other is second and smaller and is a reverse thread.

5. Screw the cog on to the right and the locking screws on to the left. Install the cog by screwing it on by hand.

6. Tighten the chain around the new cog and rotate the wheel backwards until the chain begins to act like a wrench. Continue to rotate the wheel backwards until it is hard to move, the cog is now on tightly.

7. Use a lock ring spanner to tighten the lock ring after you have begun to thread it by hand. You are now finished. Enjoy your new ride.

Tips & Warnings

• A rear brake is not necessary.
• Cogs will need to be purchased separately.
• Buying a rear wheel can be pricey, but it will save you many headaches later.
• With a reverse thread the old saying "righty-tighty, lefty-loosey" does not apply.
