Who is this bike suitable for?

The 2018 Moustache Samedi Trail 8 is the top spec alloy frame model built using decent XT components and Fox suspension with 140mm travel for trail and single track riding. A great all rounder for both UK trail centres and nimble enough to hit bigger stuff too.

Moustache know a thing or two about fusing performance with style. Their new Hidden Power project takes the high performance Samedi platform and integrates the battery inside the frame to produce an achingly beautiful E-MTB range!..  - E-Mountain Bike Magazine

New Features

The hugely popular 'Hidden Power' eMTB's from Moustache in 2018 incorporate the Bosch battery in the frame, but still easily removable for charging both on or off the bike. 

From drawings on paper to 3D printing to alloy frames in reality, Moustache developed this new setup for 2 years to create the perfect solution to Bosch eBike integration. 

The new Bosch CX motor is tilted and mounted in gravity castings within the Alloy 6061 frame with the perfect 'Q factor' and playful geometry for 2018.

Moustache 2018 Electric Bike Frame Hidden Power

Whilst the Bosch Performance 500Wh battery is cleverly located in the Trail 8's down tube, offering a lower centre of gravity and 'Hidden Power' seamless look over the longer Bosch 'InTube' batteries. They ride as nice as they look!..

Trail 8 Wins eMTB of the Year Award

Moustache 2018 Trail 8 eBike

The new 2018 Moustache Trail 8 electric mountain bike wins eMTB of the year award. The Judges said:-

 The Samedi gets the highest score on all criteria related to the motorisation. The suspension provides the Samedi ultra-performing abilities whatever the terrain encountered. It allows great pedalling, grip, traction and, on its own, brings tremendous performance to the bike, making it extremely versatile. Almost all the jury has put forward its performance and the way the engine is sublimated by the technical choices to offer unmatched performance. In the end, it is considered so effective and efficient because of its geometry and its suspension, that nothing can block the single track to victory. The Samedi is just fun & the jury says it! Being the cheapest of all these finalists, the feat is even greater! 

Moustache have also updated the new 2018 Samedi frames to 27.5+. What's PLUS all about? This revelation hitting the cycling industry by storm offer a wider 3" tyre for ultimate traction, comfort & grip. Without compromising on rolling resistance. 

Moustache have developed their own exclusive 35mm wide rim for the Trail 8, to take the new tyre size which is fully tubeless compatible and capable of achieving the perfect balance between stability and cornering ability.

Moustache Trail 8 2018 on Magura MT Sport Brakes

Moustache have fitted the Trail 8 with Magura's new MT trail brakes. Designed with a twin piston for extra stopping power at the front. Combined with a single piston at the rear.

This offers great power to the rear and more to the front where 70% of your overall stopping power comes from.

Built on 200mm rotor at the front and a 180mm at the rear.

Minimal maintenance and fuss. Aside from changing the brake pads from time to time you can fit and forget, just concentrate on the ride!

Moustache have developed their own specific air shock with 140mm travel for the Trail 8 which offers a 2 position lockout with dynamic rebound control and their special 'Grip Control Evo' which allows for better traction at the rear. All of this is of course air adjustable to the riders preference and weight.

Up front we see the new FOX Float 34 Performance forks, for 2018 in 'eBike Optimised' specific format with a solid crown and enhanced head tube. This offers superior control and steering on a slightly heavier eBike. The 140mm travel and 34mm stations offer lightweight and agile handling over bigger forks.

This top spec alloy model is equipped with Shimano's top end XTR 11 speed drive train, featuring a clutch mech so no chain slack is offered and a wide 11 - 46t range cassette for plenty of gearing. The XTR is the cream of the crop when it comes to mountain bike trail shifting, it doesn't get better!

Moustache couple this with their optimised 14t sprocket up front for the perfect combination of descending and hill climbing capability on all the 2018 Samedi eMTB's.

Also offered up with their newly designed and reinforced cranks with a better Q factor and ultimate stiffness.

Shimano XTR on 2018 Moustache Trail 8 eBike

The new Moustache Samedi Trail 8 is effectively the alloy frame version of the Carbon Trail 9. Both lightweight and agile, matched with top end components, from FOX's eBike optimised fork to Shimano's top end XTR.

Bosch CX & Purion eBike System

The new Moustache Samedi Trail 8 2018 eBike's feature the latest Bosch Performance CX crank drive motor, so you can be sure it's fitted with the latest kit and setup for optimum performance. 

The 250w CX system outputs 75Nm of torque & peaks at 500w! It certainly packs a punch, it will also offer up to 300% assistance in turbo mode. Featuring 4 levels of assistance & remember you can always turn the power off and ride it as a normal bike! In addition, the new eMTB mode allows the user to set in one assistance mode and the system itself will determine the assistance offered.

This machine rolls just the same as a normal cycle. In fact the quality in the design, geometry & build make it a true performer! The Samedi Trail 8 eMTB features the larger capacity Bosch 500Wh Battery for 2018 so it hosts the most range possible on any Bosch powered electric mountain bike.
