Wheel One of the most frequent questions we have gotten over the years is whether one of our Stowaway Trikes can take a bigger Rear Wheel. Up until now this has not been possible. We are excited to announce the new Stowaway II 24” . We have designed an extension kit that will also be retrofittable to most Stowaways built in the last 5 years. This kit is superior to other extensions we have seen due to the fact that it uses an oversize 12mm Thru Axle for rear wheel stability and that it raises the dropout for the wheel so that the Trike can remain at the proper angle. The Stowaway II with the 24” wheel and standard 30 Speed has a gear inch range of 19.9” to 113.2” . The new Stowaway II 24” is priced at $ 2299 with your choice of 170mm or 160mm Crankarms. We will also have a few available with 152mm Crankarms. Stowaway 24? and 26? Upgrade kits are available for any Stowaway Trike from 2015 to the present. You can check via your serial # which will begin with a number 15 or greater. The kits include a 24? or 26? Wheel including a Tire and Tube, a 24? or 26? Frame extension, a 12mm Thru Axle, a new fender, and a set of longer rack rods. You will need to move your cassette from the old wheel to the new. **Add $125 to price shown to cover incrued shipping costs

One of the hottest trends in the market- both 2 and 3 wheelers- has been Fat Tires. And who wouldn’t want one? They are a blast to ride on rough roads, trails and sand. In all honesty though for most of us, it’s not going to be your only ride. In addition, because of the nature of what you will be riding a Fat Trike on- your Fat Tire trike is likely to take more of a beating than your shiny pampered road trike. With this in mind we set out to design a Fat Trike that would meet certain criteria: Affordable: Again- this is not likely to be your only Trike, is going to take more of a beating than your other Trike, going to ride in Mud, Snow, Sand etc- so you don’t want to invest a fortune in it. Foldable: Since our premise is that it will be sharing space in your garage with your rides, and the fact that Fat Tire Trikes are just BIG- it would be nice if it took up a little less space. Unsuspended: There are 2 schools of thought on this obviously, and of the Fat Tire Trikes in production now, ICE & Sun, use suspension, Azub, and we do not. Here is our reasoning- First they are Fat Tires (duh) ! You are running these at approximately 10PSI- this gives you all the suspension you need. Secondly suspension- especially nice suspension- adds a lot of cost, weight, and complexity. Fun: Fat Tire Trikes are great fun to ride, but if you have ridden all the brands- you will definitely realize some steer and ride way better than others. Great handling and comfort is a must We are pleased to introduce our FOLDABLE Terrain 20 and Terrain 26 Fat Tire Trikes. The Terrain models are available with either 3 20" x 4" Wheels or 3 26" x 4" Wheels. Terrain Models feature a powder coated , foldable Chro- Moly frame. Terrain models will come equipped with our signature Mesh Seat with 4 adjustable angles and 3 height positions. X Seam Ranges have also been increased – the Terrain will accommodate riders with X Seams from 34 ¼" to 47 ¼" (900mm-1200mm ). We can also accommodate even larger X Seams with an XL Boom ($40 additional) . Rounding out the features are Avid BB5 Disc Brakes with locking Parking Brake Levers and a 7 Speed Shimano Drivetrain with a Twist Shifter. The Terrain 20 has a weight limit of 275 Lbs. The Terrain 26 has a weight limit of 325 Lbs. An Electric Power Assist Version of the Terrain 20 is available in limited quantities.

Hydraulic disc brakes and an 11-speed drivetrain keep the ride feel consistent and intuitive. This is the perfect bike for when you need a little extra grip rolling over tricky roots and rocks.

Much like its larger-wheeled sibling, the Mahuna, the Cinder Cone is the perfect all-rounder for the person looking to ride off-road or cruise around the backwoods bike paths. It features an air fork with 100mm of travel, as well as a dependable 11-speed drivetrain and disc brakes. If you're a fan of plus bikes, you can run up to 2.8" tires. The Cinder Cone is where the mountain meets functionality at a great price.

The Dew Deluxe is the workhorse of choice for commuters from all around the world, whether riding to work or to the grocery store. A reliable, easy-to-ride bike ensures a safe and efficient ride every time you're on it.

We're excited to see where people take the Ecoco. It's going to make quick work of running errands. It's the perfect boardwalk beach cruiser. Its sleek metallic black paint on its low-slung step-through frame with internal battery goes with pretty much everything, and its Shimano E6100 motor ensures that you'll make it to the top of that big hill in time to watch every single sunset. Dependable Shimano shifting and disc brakes will keep all the moving parts running smoothly. It comes with fenders, front and rear lights, and a kickstand. The only thing needed, is you! Kona 6061 Aluminum Kona 7005 and 6061 Aluminum alloys are used extensively throughout our fleet of mountain and asphalt bicycles. A tough, durable, light alloy, 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. 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.

This Kona classic brings some of the finer things to light. The Fire Mountain is running a smooth-shifting 9-speed drivetrain to keep things manageable across varying terrain and hydraulic disc brakes to stop on a dime.

Available for smaller riders in a 26" wheeled XS version and a 27.5" wheel for sizes S-XL. Wheel size: - Size X-Small: 26-inch - Sizes Small – X-Large: 27.5-inch

How do you improve on a bike that already feels pretty damn close to perfect? Steel seemed like a solid move. Helping to smooth out your ride and turn heads, the Rove DL (formerly called the Rove ST) features a stunning Kona Butted Cromoly frame and Project Two Cromoly Disc fork. A reliable SRAM Rival 1x11 drivetrain and TRP Spyre C brakes ensure the bike functions as nicely as it looks. The all-new Rove DL is running on WTB KOM Light Team i23 TCS rims wrapped in WTB Venture TCS 47mm tires, making it ready for anything! 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 dimension of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. 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.

Sometimes we hit a crossroads where the pavement ends, and the dirt begins. Enter the Rove NRB. 650B wheels, our new carbon flat mount disc fork featuring tons of mounting options, and mechanical disc brakes mean that transition from pavement to dirt is seamless. Couple those features with a SRAM Apex 1x drivetrain, and the Rove NRB is begging to take you away from your traditional route and into territories unexplored.

Whether you’re a seasoned dirt jumper or just learning to cruise your neighborhood pumptrack, the Shonky is the perfect weapon of choice for the jibby side of biking. A Cromoly butted frame holds a Manitou Circus Expert 100mm tapered fork that gives you just enough suspension to save your wrists. Fast-rolling Maxxis DTH 26x2.3” tires sit aboard WTB ST i30 rims. Run as a singlespeed, as all proper dirt jump bikes should be, the Shonky is a party waiting to happen.
