Stacked official word: 
Your 20" Kink Nathan Williams is a top tier pro level street and park bike, that is why it is Nathan Williams signature complete bike. This bike is light enough for high bunny hops and strong enough for big drops. The frame has a long 21" top tube, pro geometry and is supported by full 4130 chromoly tubing. The handlebars are a large 9.25" Nathan Williams signature bars to give tons of room in the cockpit. The forks are 4130 chromoly with a 1 pc steerer tube to prevent them from bending. They also feature a dual offset adapter that can be easily change out. The heavy duty sealed wheels will hold up to any grind and come with the 4 Cinema C4 plastic pegs. The rear hub is a mission freecoaster to allow you to do tricks rolling backwards or forwards. Your feet are supported by the super light Kink tubular 3pc cranks and have a super spinning sealed mid bottom bracket. The small 25t Cinema Reel Guard sprocket reduces weight while pedaling exactly like the big sprocket bikes. The brakes have massive braking power due to the 990 technology and the stiff aluminum. The seat is a aftermarket Cinema waxed canvas which is fully adjustable, making this bike perfect for any rider. Purchase this bike today, and the streets are calling.

Pro Level Components. Signature Street Geometry. Built to Progress.

Tired of upgrading your beginner BMX bike one component at a time?

The Kink Williams BMX Bike is a premium 20 inch freestyle BMX bike designed for riders who want professional level components, modern street geometry, and a complete BMX built around the riding style of professional BMX rider Nathan Williams.

As Kink BMX's flagship signature complete bike, the Williams combines a 100% 4130 chromoly frame, fork, and handlebars with a sealed Cinema Pilot freecoaster, Cinema 444 rims, four Cinema C4 pegs, and signature aftermarket inspired components.

Unlike many entry level BMX bikes, the Kink Williams comes equipped with components specifically selected for technical street riding, grinds, fakies, manuals, spins, and advanced freestyle BMX progression.

100% Chromoly Signature Frame

At the center of the Kink Williams is a 100% 4130 chromoly frame with double butted top and down tubes.

Its 21-inch top tube, 12.75-inch chainstay, and 75.5 degree head tube angle create a responsive street BMX setup with room for riders who prefer a longer cockpit.

The full chromoly frame provides a higher specification foundation than the high tensile steel frames found on many beginner BMX bikes.

Kink Williams Adjustable Offset Fork

One of the standout features of the 2027 Kink Williams is its signature 100% 4130 chromoly fork with adjustable 20mm and 25mm offsets.

This gives riders two front end geometry options without replacing the entire fork.

The shorter offset offers a more responsive steering feel, while the longer setting can provide a slightly different balance of responsiveness and stability.

Cinema Pilot Sealed Freecoaster

The Kink Williams comes equipped with a Cinema Pilot sealed freecoaster rear hub.

A freecoaster allows the rear wheel to roll backward without continuously rotating the cranks backward while the hub is disengaged.

This makes the Williams an excellent option for riders interested in learning fakies, 180 to fakie combinations, and technical street BMX tricks.

Four Cinema C4 Pegs and Hub Guards

Want to learn double peg grinds, feebles, and more advanced street combinations?

The Kink Williams includes four Cinema C4 pegs and front and rear hub guards.

These components give riders a street focused setup without immediately needing to purchase a complete grinding package separately.

Cinema Components Throughout

The Williams features several recognizable Cinema BMX components, including:

• Cinema Pilot sealed front hub

• Cinema Pilot sealed freecoaster rear hub

• Cinema 444 rims

• Cinema Beta 25T guard sprocket

• Cinema Sync half link chain

• Cinema Williams 2.5 inch tires

• Cinema CK pedals

• Four Cinema C4 pegs

Together, these components make the Williams a higher specification complete BMX for serious street riding.

Signature Four Piece Handlebars

The Kink Williams includes signature 9.25 inch rise, four piece handlebars made from 100% 4130 chromoly with TruTherm heat treatment.

The bars pair with a Kink Brute 48mm stem to create a modern street oriented cockpit.

Brake Setup Options

The Kink Williams includes removable brake mounts and an optional Mission Cease V2 rear brake kit.

Riders can choose a brake configuration that suits their riding style.

Full chromoly. Sealed freecoaster. Four pegs. Adjustable fork offset. Premium Cinema components.

The Kink Williams is built for riders who want more from their BMX.

Why BMX Riders Choose the Kink Williams

Nathan Williams Signature Design

The Williams is developed around the riding preferences of professional BMX rider Nathan Williams.

Its geometry and component package reflect a technical street BMX approach.

Full Chromoly Construction

The frame, fork, and handlebars are all constructed from 100% 4130 chromoly.

Adjustable Fork Offset

The signature fork allows riders to choose between 20mm and 25mm offsets.

Sealed Cinema Pilot Freecoaster

The rear freecoaster is designed for riders who want to roll backward without continuously backpedaling.

Four Pegs and Hub Guards

The included Cinema C4 pegs and hub guards support grinding without requiring a separate peg package.

Premium Cinema Components

Cinema hubs, rims, tires, chain, sprocket, pedals, and pegs make the Williams a component-rich complete BMX.

5 Problems You Can Run Into With Other Beginner BMX Bikes

1. High Tensile Steel Construction

Many entry level BMX bikes use high tensile steel frames, forks, or handlebars.

Although suitable for learning basic BMX skills, riders progressing into technical street riding may want higher specification materials.

The Kink Williams advantage: A full 4130 chromoly frame, fork, and handlebar package.

2. Cassette Hubs When You Want a Freecoaster

Many beginner BMX bikes come equipped with cassette rear hubs.

Cassette hubs are useful for many styles of BMX riding, but riders who want to develop fakie combinations may prefer a freecoaster.

The Kink Williams advantage: A Cinema Pilot sealed freecoaster comes standard.

3. No Pegs or Hub Guards

Some beginner BMX bikes require riders to purchase pegs and hub guards separately.

The Kink Williams advantage: Four Cinema C4 pegs and hub guards are included.

4. Limited Fork Offset Options

Most complete beginner BMX bikes use a fixed fork offset.

The Kink Williams advantage: Its signature fork provides adjustable 20mm and 25mm offsets.

5. Replacing Multiple Stock Components

Upgrading a beginner BMX with sealed hubs, a freecoaster, premium rims, a guard sprocket, a half-link chain, and street pegs can become expensive.

The Kink Williams advantage: These street oriented components are already included in the complete bike.

5 Reasons the Kink Williams Stands Out From Many Beginner BMX Bikes

1. Full 4130 Chromoly Construction

The frame, fork, and four piece handlebars use 100% chromoly construction, offering a premium structural package.

2. Cinema Pilot Sealed Freecoaster

The freecoaster drivetrain makes the Williams especially appealing to riders practicing fakies and technical backward rolling tricks.

3. Four Cinema C4 Pegs and Hub Guards

The included grind setup supports technical street riding without requiring immediate additional accessories.

4. Adjustable 20mm/25mm Fork Offset

The Kink Williams signature fork gives riders a geometry adjustment option that is uncommon on entry level complete BMX bikes.

5. Premium Signature Components

Cinema 444 rims, Cinema Beta guard sprocket, Cinema Sync half link chain, Cinema Williams tires, and signature chromoly handlebars distinguish the Williams from basic beginner complete bikes.
