Radical, modern geometry with a very long reach and a super slack head angle make this bike ideal for anyone who likes to go full gas! The Cromo frame is strong and overbuilt, but at the same time light and responsive. It will be a perfect platform for building an aggressive 29” trail bike. Fitted with a good 140mm fork and dropper post, the Eccentric will fly across trails and put the kind of smile on your face that only a hardtail delivers.

DESCRIPTION

The beautiful carbon Define is now available in metal. It was a big challenge to translate the complex lines of this bike to another material, and we have sweated every detail of this high-end alloy frame to make it as light and as sexy as possible. Some of the unique features include an adjustable BB height and semi-integrated cable guides - a practical and elegant solution of the internal / external cable routing dilemma. Big sealed pivots keep it stable and guarantee long periods of smooth, service free function. There are a few things that we borrowed directly from the Snabb - and that is the kinematics of the 4-bar suspension that everyone loves (Pinkbike: "There is so little pedal-induced bobbing at play here that it sort of boggles the mind”).

GEOMETRY

At Orange Bikes it's all about the ride, and we've made substantial improvements to our e-bike chassis which deliver the most engaging trail feel, The 170mm travel Surge will take on the biggest terrain, and is not shy when is comes to sending those gaps. Excelling where the uplift doesn't go. Some of the best trails lie beyond where your lift pass takes you – enter the Surge.

The second generation of the Surge E.P.O. model incorporates the new Shimano 8035 battery technology which has allowed us to revise of the ergonics of power assist controls - it's one those little things that can feel like a big difference.

Big adventures and an e-bike with big ideas, way above the lift station. Fast and sure footed, the stability in the Surge's geometry will give you confidence on any trail. 

The updated Surge is a revelation and we urge you to try one. E-bikes can be a devisive topic, but once you are bitten by the bug they are hard to resist.

CONSTRUCTION

Something that was painstakingly pored over was the suspension characteristic of the new Alpine 6, with everything we gained from that bike we wanted it to translate across into the Surge. Revisions have been made to the shock mounts to accommodate the new metric rear shock (230x65) and the increase in travel from 160 to 165mm, we have also focussed on increasing the amount of progression in the system which has seen a substantial increase, reduced the bike's anti-squat value and decreased the amount of pedal kickback in the system.

The new Surge’s redesigned front triangle accomodates the new Shimano 8035 battery system in under an integrated battery cover within the reprofiled downtube. The profifle of the frame is now much more streamlined and the battery is easily removable for charging.

While the rear swingarm has taken cues from our 327 DH bike in its profile, this has been done to help deal with the large amounts of torque being produced by the motor, the additional overall weight of the bike and the fact that this bike acts like your own personal uplift vehicle where descents are the order of the day.

SHIMANO EP8 DRIVE UNIT

We have worked closely with Shimano since the introduction of the very first Electric Powered Orange model. The Shimano drive assist philosophy is very much like our own. Their system does what it needs to do, then stays out of the way when it's done its job, letting you ride the way you want to.

The brand new Shimano EP8 unit is an improvement in every way to the previous model, making what we considered the best even better. The new drive unit is slimmer, sleeker and more compact than its predecessor, but don’t let its size deceive you. The EP8 packs a punch with enough power to get you to the top of any epic climb. The streamlined, integrated design not only looks the part, but it also allows for increased ground clearing for when the trail gets technical.

Everything about the EP8 is designed to allow you to focus on the ride. The new unit operates with little noise, letting you to focus on the natural sound of the trails without distraction. The newly refined Trail Mode utilises all 85Nm of the EP8’s power to effortlessly and intuitively assist you on your ride. Whether tackling loose sand or steep mountain ranges, the drive unit rapidly and seamlessly self-adjusts so that you can be safe in the knowledge that you’ll always have maximum traction and control. The harder you push, the more power will be delivered to assist you, meaning that no trail is off-limits. 

The lightest full-power system, weighing in at just 2.6kg and with a 36% reduction in drag compared to the previous model, the EP8 will not hold you back. An improved clutch mechanism makes for a more responsive ride, with a smoother cut-off when pedalling above 25km/h. All of this puts you in complete control of the bike, with fluid pedalling and no surprises. The EP8 also offers an improved Walk Assist Mode, fully supporting you to push your bike with a one button control, allowing you to hop on and off with ease.

With the E-Tube Project App you can choose from 10 levels of assistance and set the maximum amount of torque best suited to your ride style across three modes, allowing for a fully customised ride before you’ve even put on your helmet. Preferences can be saved to different profiles so that you can quickly and easily switch between them for different terrains, or if swapping from the daily commute to weekend trails.

The EP8 also offers peace of mind. The smart, heat-conducting magnesium materials and a completely redesigned motor housing means that the unit handles rising temperatures on climbs easily, guaranteeing you maximum torque for longer. The new colour display is also fitted with an anti-theft mount and is optimised to be visible in bright sunlight, meaning that you can spend less time with your head down and more time enjoying what the bike has to offer.

The Zest 24 is a proper no-compromise mountain bike designed around junior riders’ needs. Whether they are heading for the hills, taming red routes or just mucking about in the woods it’s ready for adventures, big and small.

A bike designed to tackle whatever is thrown at it has to be tough and easy to handle, so we scaled down our trademark confidence-inspiring geometry whilst keeping the fun full sized. The Zest 24’s aluminium frame offers the same blend of high strength and low weight you’ll find on our larger bikes along with the same common sense features.

A frame as capable as this deserves high-performance components. 65mm travel GRIND suspension forks help to keep the flow through the rough stuff while hydraulic disc brakes give greater control and stopping power to smaller fingers. SRAM’s NX 11 speed drivetrain offers slick and reliable performance with a wide spread of gears to help with scaling climbs and scolding descents.

 THIS HARDCORE HARDTAIL'S THE ONE TO BEAT

The Orange Crush is a bike you don't want to mess with. It's loved and revered, with award winning performance. It's the definitive aluminium hardcore hardtail.

The frame is bang on point, the rear triangle features a 148 Boost bolt-through axle, giving unparalleled stability to what is already a strong and rigid chassis. The model's geometry runs a 64° head angle which, matched with the Crush’s long top-tube design, adds an extra degree of confidence in the handling. With a short 50mm stem the rider is right where they need to be for direct control and weight distribution. Short chainstays make climbing as sweet as ever for a long-forked hardtail, those stays now reshaped with a CNCed yoke on the chainstay to allow plenty of clearance for a more than chunky 2.6 tyre.

The Crush’s unshakeable attitude is as strong as ever. Built tough to be ridden hard, where it really excels, on the rough stuff.
