Moustache Wide 4 2021


With its refined aluminium frame and brand new Bosch Performance CX line motor equipped with a 625Wh PowerTube battery, the 2021 Moustache Wide 4 is at the forefront of eMTB technology.

Sporting 130mm of front travel matched with 120mm of rear travel, 27.5+ tyres, 11 speed drivetrains and powerful Shimano brakes, the Samedi 27 Wide 4 is ready to roll straight out of the box onto your favourite trails.

The Moustache Wide was specifically designed for recreational riders who’re looking for comfort and control when riding off-road. The WIDE’s geometry is predictable and responsive, meaning you don’t need to exert as much energy when maneuvering the bike as you do on more aggressive mountain bikes.

The 27.5+ tyres offer traction and control in spades. With these predictable tyres you know you’ll be in control when riding off road, no matter the surface. These tyres are also extremely comfortable, meaning you can stay in the saddle for longer.

The 2021 Moustache Wide 4 features the new Moustache Magic Grip Control shock. This shock features 2 pedalling platforms and rebound damping, allowing the rider to fine tune the shock’s feel to their terrain and riding style. The new shock is matched with 130mm travel forks throughout the range, providing a balanced overall ride feel.

The finishing touches across the Wide range show this truly is the trail rider’s eBike, with size-specific dropper post lengths and sturdy Maxxis rubber specced throughout the range.


The new Bosch Performance Line CX system features 85Nm of torque, faster responses to pedalling and a reduction in weight and size. This is matched with the elegant new PowerTube battery, which features enhanced cooling technology to keep you riding for longer.

Though we’re a bike shop that sells, builds and fixes bicycles, they’re really just the means to an end; albeit a beautifully designed means to an idyllic end. Our job most importantly is to encourage as many people as we can to get out and ride for transport and enjoyment. We'd love to make riding a bike as commonplace as your morning cup of coffee, which by the way is our other obsession.
