Saracen Ariel 50E Elite

About the Saracen Ariel 50E Elite

Saracen's Ariel 50E Elite sits at the sharp end of their e-MTB range, a bike that borrows heavily from the brand's downhill racing pedigree and wraps it around a motor that'll haul you back to the top. Built around a hydroformed 6013 alloy frame with Saracen's TRL suspension platform - the same linkage-driven single-pivot design honed on their Myst DH bike - it pairs 160mm of Fox 38-E Factory travel up front with a 150mm Fox Float DHX2 Factory coil out back. The Shimano EP8 motor delivers 85Nm of torque, fed by a substantial 720Wh Darfon battery tucked inside the downtube, and the whole package tips the scales around 25 kilograms. It's a hefty proposition, but one that makes sense when you consider what it's built to do.

This isn't a bike that apologises for its weight or tries to be something it's not. The geometry is slack and long, the suspension is plush and progressive, and the component spec - full Shimano XT drivetrain and brakes, RaceFace carbon bars, a KS LEV Integra dropper - reads like a wish list for anyone who spends more time pointing downhill than up. Saracen includes a convertible linkage in the box, so you can run it as a full 29er or flip to a mullet setup with a 27.5-inch rear wheel, tweaking the handling to suit your local trails or your mood. It's a thoughtful touch that adds versatility to a bike already brimming with capability.

The Ariel 50E Elite is designed for riders who want to session descents without the faff of shuttling, who'll gladly trade a bit of weight for a suspension platform that stays glued to the ground when things get rough. If your weekends involve steep chutes, rooty gullies, and the kind of terrain that makes you check your brake pads afterwards, this bike will feel like it was built for you - because it was.

Saracen Ariel 50E Elite geometry

The Ariel 50E Elite's geometry leans heavily into stability and confidence at speed. Reach figures stretch out across the size range, putting you in a centred, balanced position that favours descending over tight, twitchy climbing. The head angle sits around 64 to 65 degrees depending on setup, slack enough to inspire confidence when the trail tilts down but not so extreme that it feels unwieldy on mellower terrain. Paired with a 76-degree seat angle, you're pushed forward over the pedals when climbing, helping to keep the front wheel planted even when the motor is doing most of the work.

Chainstays are a consistent 465mm across all sizes, short enough to keep the bike feeling playful in tight corners but long enough to prevent the rear wheel from getting too lively under power. Wheelbase grows as you move up through the sizes, stretching out to well over 1,200mm on the larger frames, which translates to a planted, composed feel at speed. The bottom bracket sits relatively low, dropping the centre of gravity and adding to that glued-to-the-ground sensation, though it does mean you'll need to pick your lines carefully over roots and rocks if you're not carrying speed.

When you switch from the full 29er setup to the mullet configuration, the geometry shifts subtly - the rear end drops slightly, quickening the steering and making the bike feel more agile in tight, technical sections. It's not a night-and-day transformation, but it's enough to notice, and it gives you a way to fine-tune the bike's character without buying a second frame. Stack heights are generous, keeping the front end high enough that you're not diving over the bars on steep descents, and the overall package feels like it's been optimised for riders who want to go fast when the trail points down.

Component choices & upgrades

The stock build on the Ariel 50E Elite is already impressively sorted. Fox Factory suspension front and rear, Shimano XT 12-speed drivetrain, four-piston XT brakes with 203mm rotors, and DT Swiss HX 531 rims built to handle the extra demands of e-bike duty - it's a spec sheet that doesn't leave much room for complaint. The RaceFace carbon bars and Turbine stem keep the cockpit stiff and responsive, while the KS LEV Integra dropper offers 150mm of travel (125mm on the Small) with clean internal routing. The Maxxis Minion DHRII tyres in 2.4-inch width provide predictable grip, though they're running EXO casings rather than the burlier DoubleDown or DH options.

If you're planning to push the bike hard in rocky, root-strewn terrain or spend a lot of time in bike parks, upgrading to a more robust tyre casing - DoubleDown or even a full DH casing on the rear - will save you from trailside punctures and give you more confidence to lean into rough sections. The stock tyres are capable, but they're not indestructible, and the bike's weight and power can punish lighter casings over time. Similarly, if you're on the heavier end of the rider spectrum or prefer a firmer rear end, swapping the coil spring in the DHX2 shock is straightforward; Saracen specs different spring rates by frame size, but your riding style and weight might demand something different.

Beyond that, the stock build is hard to fault. The Shimano XT drivetrain is reliable and precise, the brakes have plenty of power and modulation, and the suspension is as good as it gets without stepping up to custom tuning. If you're chasing marginal gains, a lighter set of pedals (the bike doesn't come with any) and perhaps a carbon seatpost could shave a few hundred grams, but honestly, on a 25-kilogram bike, you're better off spending your money on riding more and worrying about weight less. The Ariel 50E Elite is built to be ridden hard, and the stock spec reflects that.

Where the Saracen Ariel 50E Elite excels

The Ariel 50E Elite is outstanding at one thing above all else: descending. This is a bike that feels at home on steep, technical trails where the suspension needs to work hard and the geometry needs to inspire confidence. The Fox Factory suspension soaks up repeated hits with a smoothness that lets you carry speed through rough sections, and the slack head angle keeps the front wheel tracking predictably even when the trail gets loose or off-camber. If you're the kind of rider who lives for the descent and tolerates the climb, this bike will feel like it was built specifically for you.

It's also excellent for riders who want to session trails without the logistics of shuttling. The 720Wh battery and efficient Shimano EP8 motor mean you can rack up serious vertical without running out of juice, and the motor's customisability via the E-Tube app lets you fine-tune power delivery to match your riding style or conserve range on longer rides. The convertible linkage adds another layer of versatility - run it as a 29er for stability and speed, or flip to a mullet setup for a more playful, agile feel in tighter terrain. It's a bike that adapts to your needs rather than forcing you to adapt to it.

Where it's less ideal is on mellower, flatter trails where the weight becomes more noticeable and the suspension feels like overkill. The Ariel 50E Elite is built for big hits and steep gradients, and if your local trails are more cross-country than enduro, you'll find yourself wishing for something lighter and more nimble. It's also not the bike for riders who prioritise all-day comfort over outright capability - the aggressive geometry and firm suspension tune are designed for performance, not for cruising. If you're after a do-it-all e-MTB that's equally happy on fire roads and black-diamond descents, this isn't it. But if you want a bike that'll let you ride harder, faster, and with more confidence on the kind of terrain that makes your mates turn around, the Ariel 50E Elite delivers.

Saracen Ariel 50E Elite FAQs

What is the weight of the Saracen Ariel 50E Elite?
The Ariel 50E Elite weighs around 25 kilograms, which is typical for a full-power e-MTB with this level of suspension travel and component spec. It's not a light bike, but the weight is a trade-off for the robust frame, large battery, and downhill-capable suspension.

What is the battery capacity of the Saracen Ariel 50E Elite?
It's fitted with a 720Wh Darfon battery, one of the larger capacities available on e-MTBs. That translates to extended range, especially if you're using the motor efficiently, and it means you can tackle longer rides or more vertical without worrying about running out of charge halfway through.

Is the Saracen Ariel 50E Elite good for climbing?
It climbs capably thanks to the Shimano EP8 motor and the 76-degree seat angle, which keeps your weight forward over the pedals. The suspension platform offers a decent climbing mode, and the motor's torque makes short work of steep pitches. That said, the bike's weight and downhill-focused geometry mean it's not as nimble or efficient on climbs as a lighter, more XC-oriented e-MTB - but it'll get you to the top without complaint.

What type of riding is the Saracen Ariel 50E Elite best suited for?
It's best suited for enduro, aggressive trail riding, and bike park sessions - anywhere the trail points down and demands confidence, capability, and suspension that can handle repeated big hits. If you're spending most of your time on steep, technical descents and using the motor to get back to the top, this bike is in its element.

What are the suspension travel figures for the Saracen Ariel 50E Elite?
It runs 160mm of travel up front via the Fox 38-E Factory fork and 150mm of travel at the rear through the Fox Float DHX2 Factory coil shock. That's a generous amount of travel for an e-MTB, and it's tuned to handle the extra weight and forces that come with a motor and battery.

Can I convert the Saracen Ariel 50E Elite to a mullet setup?
Yes, Saracen includes a convertible linkage in the box that lets you switch between a full 29er setup and a mullet configuration with a 29-inch front wheel and a 27.5-inch rear. The swap changes the geometry slightly, making the bike feel more agile and playful in tight terrain, and it's a straightforward process that doesn't require any special tools.

What motor does the Saracen Ariel 50E Elite use?
It uses the Shimano STEPS EP8 motor, which delivers 85Nm of torque and is known for being quieter and more customisable than earlier Shimano motors. You can fine-tune power delivery, assist levels, and other settings via the Shimano E-Tube app, which is a nice touch if you like to tweak things to suit your riding style or terrain.

What is the difference between Saracen Ariel models?
The Ariel range includes both electric and non-electric models, with different levels of spec and intended use. The Ariel 50E Elite is the top-spec electric model, focused on enduro and aggressive trail riding with Fox Factory suspension and Shimano XT components. Other models in the range, like the Ariel 60 Elite, are non-electric and more gravity-focused, while the Ariel 30 Elite is a lighter, more trail-oriented non-electric option. The key differences come down to suspension travel, component spec, and whether or not there's a motor involved.
