The Strider Sport has a seat height range from 28-48 cm (11-19 in.), which means it fits a huge range of inseam lengths (30-51 cm [12-20 in.]).

SIDEWALK ADVENTURER Everyone remembers their first bike; the combination of freedom and fun. That bike needs to be fun, comfortable and safe, which is why Laser 16 features a lightweight aluminum frame, removable training wheels, and BMX-style handlebars and saddle. LIGHTWEIGHT ALLOY FRAME Extra weight is the enemy of any bike. This is especially true for youth bikes, when the riders themselves are relatively light-weight. It’s tough to beat the cost-to-weight ratio of aluminum, which is why Laser 16 features a lightweight 6061 aluminum frame. This keeps the overall weight down, making the bike much more fun and easy to ride. TRAINING WHEELS INCLUDED When it comes to learning to ride a bike, building confidence is the name of the game. Laser 16 is equipped with training wheels, so young riders can build that confidence safely. - Lightweight 6061 aluminum MX-moto frame design - Tubular unicrown fork, MX Hi-Ten, straight blades - Electro-plated black steel rims, steel front and Hi-Stop coaster brake rear hubs - CST Dirt Knobbie tires - BMX high-impact resin pedals - Hi-Stop rear coaster brake - BMX style handlebar with a safety bell - Jamis BMX Jr. saddle

Kona 6061 Aluminum Kona 7005 and 6061 Aluminum alloys are used extensively throughout our fleet of mountain and asphalt bicycles. Tough, durable, and light alloys, both Kona 7005 and 6061 deliver fantastic, reliable performance that lasts for thousands of rides. Much of our 7005/6061 tubing is butted and/or formed, meaning the tubing's wall thickness can be increased or decreased as well as shaped, so we can fine-tune a particular frame's strength and ride characteristics depending on its intended application. Internal Headset Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible.

The Honzo 20 is for the mini ripper who has no problem keeping up with the older sibling and needs a bike that rides hard too! A redesigned frame fits wider 20x2.6" Vee Tire Crown Gem tires, making it easier to roll over obstacles on the trail.

Steel Commuter and Gravel Bike Preamble is a hard-boiled steel commuter built for comfort, durability, and buffoonery on pavement and gravel. Nothing More is Needed. Nothing Less Will Do. The challenge was thus: Build a serious steel bike and give it only the attributes that matter most. Make it quick and comfortable on pavement, as well as confident and compliant on degraded surfaces. What the Enginerds put forth is Preamble, a pavement and gravel utility worker that proves you don't need to cut corners or clip coupons to make a more affordable steel bike. You just need to keep shit simple. Preamble can run racks and fenders and carry a couple water bottles. Surly was raised on stealing basic cable, after all. Smooth and efficient on asphalt, Preamble's double-butted main triangle provides a resplendent ride feel and withstands abuse from life's inevitable potholes. Make it your own with flat bars, drop bars, a basket, or bags. On the road to steel euphoria, Preamble is the gateway drug. Let facts be submitted to a candid world: - Offered in flat-bar and drop-bar configurations - Easy T-Shirt sizing to fit nearly every rider (XS, S, M, L, XL) - Sloping top tubes on XS and Small frames for improved standover and comfort - To offer the best rider experience for every frame size, XS and S frames get 650b wheelsets while M–XL get 700c - Custom-cast single-position vertical dropout

Often imitated, but never duplicated, the Honzo is a part of Kona's foundation. The Honzo is the solution for the rider wanting something a bit more aggressive than a traditional cross-country hardtail.

Whether you're a seasoned rider looking for a timeless hardtail or a newer rider looking to go a bit deeper into the mountain bike world, the Honzo is an excellent choice.

The Unit X has become a cult favorite among die-hard Kona fans. Maybe it's the Cromoly frame. Maybe it's the fact that it's a bike packing monster, or its well-geared 12-speed drivetrain, or modular dropouts which give you the ability to run it as a single speed if that's your thing. Maybe it's because the rigid fork makes it that much more of a classic. We may never know why the Unit X is such a popular bike, but we can only guess it's because it is one of the most practical machines in our lineup. REYNOLDS 520 CROMOLY Reynolds 520 tubes are mandrel-butted for accurate profiles and available in a wide range of shapes. Weight savings from butting provides competitively priced, light framesets that are noticeably compliant on the road or the trail, and are guaranteed to last a lifetime. INTERNAL HEADSET Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible. 44mm HEAD TUBE 44mm headtubes are a versatile spec which works with both straight and tapered steerers by switching out the lower headset cup. The stock configuration is internal and is for 1 1/8" steerer. Switching to an external lower cup allows for the use of a tapered 1.5" steerer. The best of both worlds. TUBELESS COMPATIBLE RIMS Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems. 12x148mm AXLE 12x142mm, 12x148 and 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142/148/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted.

VERSATILITY Renegade enables you to be a commuter in the morning, leader of the after-work group ride and take off for a 300-mile bikepacking expedition over the weekend. All with a single bicycle. With over 20 fork and frame mounts you can now choose to mount fenders, rear carrier, low-rider front carrier (or two cages for water bottles/storage) and three front triangle water bottles. Add clearance for 700 x 50mm and 650 x 2.00"* on our steel and aluminum models, and it's clear the Renegade series is equipped to accommodate any adventure. *Renegade carbon models are designed to accommodate up to a 700c x 37mm tire without fenders or 35mm with fenders. *Steel and aluminum Renegade models are designed to accommodate up to 700c x 50mm tires without fenders and 35mm with fenders. ADVENTURE FRAME DESIGN Starting with a wide and consistent stack and reach range, we set out to design a frame that could handle on or off road conditions while maintaining a comfortable and consistent ride. As you start to review the geo chart you will notice we have 3 different fork offsets, BB drops and rear center measurements depending on frame size. This is unique. We set out to ensure every Renegade rider will experience the ultimate in adventure bike performance regardless of their frame size. Most of our competitors simply design one fork and strap it to every frame size. While this may work just fine for a bicycle that's designed to be ridden with a single tire size (think a road racing bike), it significantly impacts the handling and ride quality of an adventure bike when swapping out your 28's for 32s, 40s or even 47mm tires. Add size specific tubing, where we vary the diameter of the frame tubing depending on frame size and 2 different sized rear triangles and you have what we feel is the perfect adventure geometry for all sized riders and the best riding adventure bike period.

FULL RANGE The Renegade is ready for any adventure, no matter which Renegade you ride. The long and tall endurance geometry is designed specifically to ride comfortably all day on the road or in harsh conditions off-road. The smooth ride of the full carbon fiber Renegades set the bar for how we designed the steel and aluminum bikes. With disc brakes and the ability to mount up to a 47c tire, these bikes are ready to go just about anywhere. All you need is the desire to push, pedal and explore. With a full range of sizes from 44 with 650 wheels to 61cm there's always a Renegade designed just for you.

You're looking for a smooth ride across mixed terrain. You're a fan of steel. You have discerning taste but aren't caught up in trends. You want a bike that looks good, rides great, and will last you a lifetime. You're the person that buys a great product at a great price. Look no further than the Rove DL. It's been a workhorse for years. Inspired by mountain biking, but decidedly more touring oriented, the Rove DL checks all the boxes for functionality, comfort, and style. KONA CROMOLY Very few materials offer as much shock absorption, durability and supple-ride characteristics as steel. We've never strayed from cycling's original material and have worked tirelessly to adapt, refine and innovate Kona Cromoly framesets as rider demands continue to evolve. TAPERED HEAD TUBE More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it's needed. TUBELESS COMPATIBLE RIMS Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems. 12x142mm AXLE 12x142mm, 12x148 and 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142/148/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. For 2017, you'll see the 12x148 Boost standard in the mix. Boost spacing provides more tire clearance at the chainstay yoke, while the rear wheel is stiffer and more durable relative to a 12x142 thru-axle. 650b WHEELS 650b wheels and tires have a similar overall diameter to a traditional 700c gravel or commuting tire, but with a smaller diameter rim and a wider, taller tire. The extra air volume in this new generation of urban and mixed-surface tires means they can be run comfortably at lower pressures while still rolling quickly on a variety of surfaces. It's the best of both worlds.
