Moustache Mardi 27.4 FS

The urban e-bike that makes everyday life easier

The Mardi 27.4 FS is built for maximum comfort around town. Front and rear suspension, wide tyres, an ergonomic saddle and an adjustable riding position help smooth out cobblestones, potholes and rough city streets.

Its Bosch Performance Line PX motor delivers powerful, natural-feeling assistance, while the 600Wh battery provides plenty of range for commuting, errands and longer weekend rides.

A Shimano Nexus 5-speed internal hub lets you change gear easily, including while stopped. Paired with a Gates belt drive, it offers quiet, clean and low-maintenance everyday riding.

Easy to use

The low-step frame makes getting on and off straightforward. A remote-operated dropper seatpost lets you lower the saddle at traffic lights, making it easier to place your feet securely on the ground.

The five internal gears are controlled using a simple twist shifter and can be changed while stationary.

Double suspension comfort

A 100mm SR Suntour suspension fork absorbs bumps at the front, while Moustache’s Magic Grip Control rear shock adds comfort beneath the rider.

The Selle Royal Essenza+ saddle, ergonomic grips and swept-back adjustable handlebar support a natural, relaxed riding position.

Powerful Bosch assistance

The Bosch Performance Line PX Smart System motor produces up to 90Nm of torque, giving the Mardi strong assistance on hills and when accelerating.

The integrated Bosch PowerTube 600Wh battery offers a claimed maximum range of approximately 137km under ideal conditions. An optional Bosch PowerMore 250Wh range extender can increase total capacity to 850Wh.

Everyday security

An AXA frame lock makes it easy to immobilise the bike during quick stops. A compatible plug-in chain can be added to secure the bike to a fixed object.

The battery uses an ABUS XPlus lock with the option of matching keys through the ABUS One-Key system.

Adjustable riding position

The adjustable stem allows the handlebar to be raised for a relaxed, upright position or lowered for a slightly more active and efficient riding position.

Ready for daily transport

The Mardi 27.4 FS includes full-length alloy mudguards, integrated lights, a kickstand and a rear carrier.

The suspended rear carrier is compatible with MIK HD and QL3 accessories, allowing riders to fit panniers, baskets, crates or a compatible child seat.

Through the Bosch Smart System and eBike Flow app, riders can access features including:

  • Navigation
  • Customisable assistance modes
  • Display settings
  • Additional theft-protection features

How to Choose the Right Electric Bike

When you chat with us - whether in the shop or online - we’ll usually start by asking two simple questions:

Where do you want to ride? Do you tackle a big hill, cruise a long flat commute, or a bit of both?

Do you need to carry anything? Is it cargo, a kid, or a mix of everything?

Big hills usually mean more power and stronger brakes. Long commutes might call for a high-speed option with a larger battery. Carrying kids or heavier gear might mean looking at stability and the right accessories.

It can feel overwhelming with so many models out there, but that also means there’s a perfect match for your lifestyle. We’ll help you find it - and you can take a test ride to make sure it really fits into your day-to-day.

If you want to explore yourself on our website, go to our electric bike page and use the filters to narrow down your options based on how you answered the questions above.

Non-electric bikes are fine for flat, short trips with lighter loads, or more recreational endeavors. But if you’ve got hills, longer distances, or a wriggly kid or gear on board, an electric bike will change your life. The motor takes the sting out of climbs, makes heavy loads manageable, and opens up bigger commutes sans sweat.

Worried you'll get lazy? Honestly, it doesn't happen. If anything you'll find yourself riding your bike more knowing you have that electric support - think those occasions when you need to do a small grocery shop or pop into town for a dinner. Easier to grab the bike than the car. Plus you can still push it just as hard! You'll just get places faster.

Do I always need to fully charge my e-bike?

No! If you just need a top-up to cover your ride, charging to 50% is fine. A good rule of thumb for prolonging battery life is to avoid consistently running it flat. We suggest charging before it drops below 20%.

Modern e-bike batteries are managed by a Battery Management System (BMS), which protects the cells against overcharging, deep discharge, and overheating - so you can charge with confidence.

In most cases, the battery can also be removed from the bike and charged indoors, which is convenient in winter or if you don’t have power access where you park your bike.

Yes. Most electrics bikes - especially ones for commuting - come equipped with a rear rack. Pannier bags or child seats can easily be fitted in most cases.

When riding an e-bike there is no need to be tucked down low into the wind as the motor simply pushes you through it, but if you’re an experienced rider you may find that a sporty riding position is more familiar and comfortable. If you’re new or newly returning to cycling you might prefer an upright step-thru bike, generally new riders feel safer riding upright. Perhaps you’d like a mix of both in which case a mid-step frame will typically give you that semi upright riding position. The riding position on most bikes can be customised somewhat with adjustable handlebars and seat positions. We can help you with this in-store. Use the frame style filters in our shop pages to choose your desired riding position.
