Raleigh Talus 1
$430.00
At home on dirt, gravel, and pavement, the Talus 1 keeps the adventure going when it's time to explore the path less traveled. To give you the ideal balance of stability and easy handling, the Talus features Progressive Wheel Sizing, using the wheel size that best matches the rider size.

Giant ATX 2
$450.00 - $475.00
Navigate urban streets, cruise the bike path, or explore forest trails. Part mountain bike, with its flat handlebar and plush suspension bike, and part city bike, ATX is at home in any environment. Closely related to Giant off-road bikes, ATX features the familiar flat-handlebar and 100mm suspension fork of a traditional XC mountain bike. A lightweight ALUXX aluminum frame, engineered with comfortable geometry for challenging terrain, adds to its rugged personality. It also uses size-specific wheel diameters—smaller size bikes use 26-inch wheels, while larger sizes use 27.5. This tailors the bike’s handling to every rider’s size and height. Powerful disc brake technology gives you confident handling in all weather or riding conditions, and integrated mounts let you easily add racks or fenders to suit your riding adventures.
Cannondale Trail 8
$485.00
Cannondale's Trail lineup generates a passion for mountain biking—from your first time out to your next big challenge. Light and lively, stiff and snappy, the Trail frames showcase Cannondale's decades of expertise in aluminum craftsmanship. Their Dirt-Tailored geometry brings both quickness and composure, with short chainstays for agility and traction, a slack head angle for unwavering stability, plus wide bars and a short stem for total control. Each Trail model is sweetly priced, but make no mistake—wide range gearing, powerful disc brakes, and durable wheels and tires contribute to big trail readiness. A mountain bike designed to raise your game and ignite a passion for the trail, naming this bike was a no-brainer.
Cannondale Trail 7
$488.72
With its progressive geometry, impressive construction and high-end features, the Cannondale Trail offers unreal performance and killer value. Built on a strong C2 alloy frame with 100mm of trail-absorbing suspension provided by the SR Suntour fork, the Trail 7 is the bike that will make you fall in love with mountain biking. The 18-speed Shimano Altus drivetrain with EZ Fire shifters provides smooth, fast gear changes, while the Shimano hydraulic disc brakes keep you in control no matter what the conditions. Durable Cannondale double-wall rims and trail-grabbing WTB tires will have you flying fast and furiously even when the trail does its best to slow you down. To optimize fit and handling, Cannondale uses 27.5-inch wheels on the X-Small and Small frames and 29-inch wheels on larger frame sizes. Dressed up with Cannondale's own high-quality aluminum components, the Trail 7 is ready for your next adventure.
Giant Talon 29 3
$520.00 - $530.00
With smooth stability and added balance, this lightweight hardtail 29er puts you in control. Built on a lightweight ALUXX aluminum frame that features classic hardtail design and the added off-road stability of larger diameter 29-inch wheels, Talon is a great choice for XC terrain. The frame geometry is specifically designed for its wheel size and 100mm suspension fork. The result is a confident ride that’s perfect for XC riders looking to increase their speed and improve their skills on fun singletrack rides. - ALUXX-grade butted aluminum frame - SR Suntour XCT HLO 100mm-travel fork with hydraulic lockout - Giant double-wall rims with Maxxis Icon tires - Shimano 3x8-speed drivetrain with Tektro hydraulic disc brakes
Surly Lowside Frameset
$600.00
Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It’s just as happy riding singletrack as it is parked outside your favorite drinking establishment. Lowside is a singlespeed. Singlespeeding has been a part of Surly’s DNA since day one when we launched the 1x1 Rat Ride. After a lot of Homie Fall Fests and more feats of strength than we can recall, we decided to discontinue it a couple years back. Lowside picks up right where the 1x1 left off. Some have dubbed the Lowside the ultimate pub cruiser. - Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles - Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though) - Clearance for 26 x 3 or 27.5 x 2.8 tires
Surly Troll Frameset
$699.00
Off-road touring can be a zesty enterprise, but it’s not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent’s basement. If you’re going to ride your bicycles where no one can see, you better take gear that’s up to the task. Troll is up to the task. Our Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. We’ve also adorned this frame with our Gnot-Boost spacing, allowing you to use any mountain bike hub whether it be 135mm QR, 12 x 142mm thru-axle, or 12 x 148mm Boost hub. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and the dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don’t get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the down tube. Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible. Man has known for eons the call of the indifferent forest. The inexorable march of time, and dumb crap like cell phones, have dulled our senses and made us afraid. Reclaim your animalistic tendencies atop Man’s greatest invention.
Surly Karate Monkey Frameset
$785.00
The Karate Monkey frame features updated, progressive trail geometry, a new tubeset, and Surly’s Gnot-Boost rear dropout system to support multiple drivetrain and wheel size configurations. - 100% Surly 4130 chromoly steel frame and fork; double-butted main triangle and 44mm headtube - Tubeset uses the same trumpet tubes found on Instigator 2.0 frame - Adjustable rear dropouts with 145mm Gnot-Boost spacing works with 142 x 12, 148 x 12mm, and 135mm w/ 10/12 washer - Internal dropper seatpost routing - 30.9mm seat tube ID - Clearance for 29 x 2.55 or 27.5 x 3 tires
Surly Big Fat Dummy Frameset
$1,650.00 - $1,730.00
The Big Fat Dummy is a long tail cargo bike that took a few too many doses of growth hormones. At first glance, you might say that Surly just put bigger tires on a Big Dummy. But if you said that, you'd actually be very wrong so just… don't. Think of Big Fat Dummy as more of a second or third cousin to Big Dummy rather than a brother. They share some of the same DNA and look sort of similar, but they're two very different bikes and really only interact when they both reach for the potato salad spoon at that family reunion that no one really wants to be at anyway. Now that that's out of the way, let's get down to the nitty gritty of what makes this hulking beast of a bike tick. Surly's goal with designing a cargo bike around fat tires was to create the most stable, stiff, and traction-laden ride possible while hauling a ton of stuff. Big Fat Dummy has a longer toptube and slacker headtube than its more svelt cousin giving it a nice, predictable, and stable ride. They also used thinner, lighter tubing to construct its cargo area so while it's an overall burlier bike, there's not much difference in weight. Big Fat Dummy accepts either 10mm or 12mm axles in the rear with a spacing of 190/197mm. That big ‘ol spacing equates to one thing: tire clearance for days. Big Fat Dummy maxes out at a massive 26 x 5.25" tire.* While that large of a tire provides the most traction and stability a bike can possibly offer, it's also a lot of rubber to push and might not be for everybody. Luckily, Big Fat Dummy is also a blast to ride with 3" tires too. It uses the same 100mm suspension-corrected fork as the Wednesday, meaning if you want to add a little squishy-squishy to your ride, you can throw a Bluto on and let ‘er rip. If you intend to carry a passenger on your Big Fat Dummy, Surly requires use of their Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility. All Big Fat Dummy framesets and bikes ship with a Dummy deck, rails, bags, and the aforementioned Dummy Rail Collars so you can immediately start hauling cargo — human or otherwise. Big Fat Dummy is ready and willing to carry all sorts of crap — literally. It's already in use on an organic farm in Ecuador so it's likely that it's hauled some form of manure by now. *Using a 26 x 5.25" tire will cause some drivetrain limitations. For all the nuts and bolts of compatibility read Surly's blog on the subject.
Wilier Triestina Jaroon Plus Rival
$2,899.00
The Jaroon Plus is the new high-end steel frame dedicated to the touring and bikepacking world. As in the Jaroon model, the Jaroon Plus is welded with a special technique that hides all welding material inside, making the frame appear clean, and the seams flawless. What’s unique about the Jaroon Plus is the 29 plus wheel sizing, 29-inch diameter with a width coverage of 3-inches. It is a sort of MTB that, thanks to the 16 degree flared out racing handlebar, becomes a hybrid born for adventure. SRAM's Apex 1 x 11-speed drivetrain easily shifts through a wide range of gears, while the SRAM Rival hydraulic disc brakes gives you the power to stop in all conditions. Technologically speaking, the frame has a rear through axle, differentiated diameter head tube, 27.2mm diameter seat-post for greater comfort, disc brake system and monocoque all-carbon fork with through axle. For maximum versatility, the frame has been designed to mount mudguards and rear rack.
Haro Shift R9
$2,999.99
Built around our new Four-bar linkage frame with up-to-date geometry and proprietary X6 aluminum tubing, the Shift R9 is the ultimate ride-anywhere-ride-anything Enduro model. With a steeper seat tube angle for more efficient pedaling plus a slacker head tube angle and longer reach for an improved attack position, the Shift R9 will satisfy a wide range of riders. With 160mm of rear travel and 170mm of front suspension provided by Rockshox, the Shift R9, with its new Shimano XT and SLX 12-speed components, allows for a smooth ride up or down the hills, under the clock or not, with a wide-range gear ratio and precise, crisp shifting. Features - Shift R X6 series 4-Bar Linkage frame, 27.5" Enduro geometry, 160mm travel, Boost thru-axle dropouts - Rockshox Super Deluxe Select R Trunnion rear shock w/ reservoir - RockShox Yari RC 27.5" Boost fork, 35mm, 170mm travel - Praxis Cadet forged crankset, M30 Axle, 32T alloy chainring - New Shimano XT 12-spd rear derailleur - New SLX 12-spd shifter & 10-51T cassette - WTB ST Light i-29 27.5" rims, tubeless ready - New Kenda Nevegal-2 27.5x2.6" tires, 120 TPI, Aramid Beads - Shimano MT 520/501 4-piston disc brakes - X-Fusion Manic 125/150mm internal dropper post & remote

Haro Shift Plus I/O 5
$4,499.99
The Shift i/O 5 is a powerful All-Mountain contender. Built upon our new 4-bar linkage frame with 160mm of rear travel and a Suntour Aion 35mm EVO Boost fork, it features Shimano's E-8000 MTB-specific mid-motor system that delivers 250 watts of power, 70 Nm of user-friendly torque, and a new internal 504Wh battery for an outstanding integrated look. A new 2021 Shimano Deore 10-speed 1x transmission keeps things simple while the Kenda Nevegal 2 27.5 x 2.6" tires with U-40 double wall rims make you feel like you are on rails around even the loosest terrain. The Tektro 745 4-piston hydraulic brakes, with their powerful braking, will bring it all to a quick stop when needed.

Cannondale Jekyll 1
$5,499.00 $8,200.00 33% Off
This precision instrument is for the enduro artists, the ones who will use its Gemini dual-travel and poppy quickness to dance and float through the chop and chunder on their way to the top step. The Jekyll delivers all the slack stability you’d expect from a top enduro rig, but with uncanny agility and snap, thanks to 27.5 wheels and the ultra-short chainstays of our Ai rear end. Asymmetric Integration (Ai) delivers some of the shortest stays on the trail, yet has more tire clearance and frame stiffness than even Boost frames can muster. Plus a rear wheel that’s stiffer and stronger thanks to the Ai even-dish build. It all adds up to the kind of agility and traction that has to be ridden to be believed. Co-developed with Fox, the Gemini system adds two ride modes (Hustle & Flow) to the killer performance of Fox shocks. Flip to Hustle to shorten the travel and ramp up the spring rate for a snappier, more responsive feel for pumping through turns, sprints, and traction-challenged climbs. Flip back to Flow for full Fox travel when things get rough. Placing a link between the swingarm and the shock allows Cannondale's engineers to customize the system's leverage ratios for optimal suspension response throughout the stroke and keep the suspension active under braking while retaining the stiffness, durability, and reliability of a single pivot design.

Cannondale Moterra SE
$8,500.00
Moterra is an e-mountain bike with infinite capability. The shackles are off, now go ride the unrideable, over and over again. Moterra is all-mountain ready, built to go hard with 160mm of trail-crushing, dialed suspension. With big, grippy tires, properly wide bars and short stems, powerful brakes and dropper posts, and a water bottle in the front triangle, Moterra is ready for the good stuff. Utilizing size-specific Center-of-Gravity data, the Proportional Response suspension linkage is tailored by size so that every rider experiences optimized suspension performance while braking, climbing, and descending. Our Ai Offset Drivetrain opens up the rear triangle for more tire clearance while keeping the chainstays short for nimble agility. A stiffer, stronger rear wheel is just icing on the cake. A Carbon frame keeps the mass to a minimum. But since our engineers prioritized durability over gram-counting, confidence is built-in (and so is a lifetime warranty). To protect the motor and battery from damage, Moterra features a sealed battery cover and a burly, trials-style skid plate. Proprietary Cannondale motor mount positions the Bosch drive unit low and forward in the frame, keeping the Center of Gravity low and the chainstays short for uncommonly agile handling. LockR pivots enable a thru-axle pivot system that creates a rock-solid connection between both sides of the swingarm for instantaneous response. No twist, no flex, and no special tools required. - Carbon front triangle, SmartForm C1 alloy rear triangle - RockShox Boxxer Select Charger RC, 180mm, DebonAir dual-crown suspension fork - RockShox Super Deluxe Select rear shock - Stan's NoTubes Flow S1 wheels - SRAM GX/NX Eagle drivetrain - SRAM Code R hydraulic disc brakes - Bosch Performance Line CX 250W motor - Bosch PowerTube, 625Wh battery
