At Ribble Valley E-Bikes, we recently got our hands on the latest e-Mountain Bike (e-MTB) from Moustache, known as the Clutch. We were eager to take it out for a test ride to evaluate how well the new gearbox system performs in real-world conditions.
The Moustache Clutch embodies a remarkable evolution for the brand, featuring a unique Pinion MGU gearbox motor and a smooth belt-drive system in place of the traditional Bosch mid-drive. With its robust aluminium frame, impressive 170 mm front travel, and 160 mm rear travel with 150 mm front and rear on the Clutch SUV, along with mullet wheels, this e-bike is expertly crafted to conquer the most challenging enduro terrains. Prepare yourself for an unforgettable ride!

At its core is the Pinion MGU, which delivers torque ranging from 85 to 160 Nm and up to 600 W of power. This system is integrated into a sealed gearbox that completely eliminates the need for a derailleur.
This setup results in cleaner and quieter trails, as there’s no chain slap or grime to deal with. Maintenance becomes straightforward—mainly limited to oiling the gearbox every 10,000 km and rinsing the belt.
The Pinion MGU offers a broad gear range of 600% across 12 speeds, and it features coast-shifting through buttons, allowing you to change gears without pedalling – a significant advantage.
Despite weighing around 27 kg, the Clutch offers a surprisingly smooth ride. The rear suspension is praised for its supple yet controlled action, which is enhanced by the reduced unsprung weight at the rear hub.

The Clutch e-Mountain Bike truly excels during high-speed descents, where it feels stable, confidence-inspiring, and composed. On technical climbs, the motor provides solid support; however, inconsistencies in gearing can interrupt momentum. While the auto-shift feature is helpful, manual shifts tend to be smoother.
The bike’s weight becomes more noticeable in slippery or tight conditions, so you’ll need to employ active riding techniques to navigate these terrains effectively.

Less Ideal For:
The Moustache Clutch and Clutch SUV are electric mountain bikes catering to different riders. The Clutch is a high-performance enduro eMTB with 170mm front and 160mm rear suspension, a mullet wheel setup (29” front, 27.5” rear), and aggressive geometry for technical trail riding, focusing on performance with advanced components.
In contrast, the Clutch SUV offers versatility and utility with 150mm suspension, a more comfortable geometry, and practical accessories like mudguards and an integrated rack. Both models use the low-maintenance Pinion MGU motor-gearbox, but the Clutch SUV is belt-driven while the Clutch provides chain and belt options.
The Clutch is ideal for experienced mountain bikers seeking performance, while the Clutch SUV is perfect for adventurers, commuters, and leisure riders looking for rugged capability and everyday practicality.
The Moustache Clutch is an innovative electric mountain bike (e-MTB) that redefines performance with its unique gearbox-belt architecture, integrated battery system, and rugged construction. It caters to riders who value:
While it is important to consider personal preferences, those who enjoy slack trails, playful handling, or frequent exploratory rides may find a lighter frame with a derailleur more suitable for their style. However, for riders focused on fast descents and year-round touring, the Clutch presents an outstanding blend of low-maintenance convenience and high performance, making it an excellent choice for adventurous biking.
