Moustache J in the test: Different… but also better?

Test / E-bike: The Moustache The J has caused quite a stir since its unveiling at last year's Eurobike. The innovative frame manufacturing, which takes place entirely in France, is a particular focus. But this full-suspension step-through bike has much more to offer.

The already extensive e-bike portfolio of Moustache The J model is being added to the lineup. This full-suspension bike, available exclusively with a low step-through frame, offers 120 or 115 mm of travel and, with its three basic versions, covers a wide spectrum from urban everyday companion to comfortable off-road tourer.

The framework: innovation from France

The most striking feature of the Moustache J is undoubtedly its frame. Unlike conventional aluminum frames, which are welded together from various parts, it uses Moustache This model uses a casting process. The frame consists of only two parts without any welds, which is a novelty in the bicycle industry.

Manufacturing process

Production takes place entirely in France, from the sourcing of aluminum from France and Italy to final assembly. This underscores the company's regional commitment. Moustache and also sets standards in terms of sustainability. The special powder coating in three colors, which does not require the solvents otherwise commonly used, fits perfectly into this picture.

Design and weight

Visually, the frame of the Moustache It's quite old and differs significantly from other e-bikes. Organic shapes, no welds – from a distance, it resembles a carbon frame much more than conventional aluminum counterparts. However, the innovative casting process comes at a price: the frame's weight is higher than that of classic aluminum frames due to the necessary thicker walls. Despite optimizations, such as the use of an internal honeycomb structure for weight reduction, the frame remains relatively heavy. Moustache The J.All is a comparatively heavy e-bike. Our J.All test bike weighed in at well over 30 kg, several kilos more than similarly equipped SUV e-bikes with traditional frames. Unfortunately, this also reduces the bike's payload to only about 105 kg.

basic concept

The Moustache The J is designed as a sporty touring bike suitable for both road and light off-road terrain. With 120 mm of front and 115 mm of rear suspension travel, it offers more than enough reserves for everyday use and even the occasional rough forest track.

Different variants and configurator

Moustache J offers the e-bike in three basic versions: On, Off, and All, each covering different areas of use. The On-Road version is primarily designed for urban use, while the Off-Road version features sportier equipment focused on off-road riding. The All-Road version combines elements of both worlds and positions itself as a versatile SUV e-bike. To meet the diverse needs and preferences of riders, Moustache A configurator is available on its website. This allows customers to customize their bikes, with the main choices being between derailleur and hub gears, as well as different battery sizes. A Shimano 11-speed derailleur system or a continuously variable Enviolo hub gear with belt drive are available, the latter offering a low-maintenance and quiet alternative. However, it comes at a hefty €800 surcharge.

Moustache J with drive swingarm

An interesting detail is the placement of the engine in the drive swingarm instead of in the main frame. This is intended to ensure efficient power transmission as the drive train is directly connected to the rear wheel. This means that less energy is lost when pedaling, which should translate into a slightly better range. The disadvantage of this design, however, is that the crank and motor are part of the unsprung part of the bike. Anyone who gets up from the saddle on terrain will clearly feel the unevenness.

Equipment

In the test we had the Moustache J.All with the 625 Wh battery. Other features include a Suntour air suspension fork and the in-house system. Moustache Magic Grip Control shock absorber. The braking system is from Alhong and consists of rather slender two-piston calipers and small 180 mm discs front and rear. The choice of drive system is quite unusual: the bike is powered by the Bosch Performance Line motor, which, with 75 Nm of torque, offers a balanced mix of power and smoothness. In contrast to the more powerful Bosch CX motor, the Performance Line is characterized by lower noise and a more natural riding feel, which is particularly advantageous for everyday use. The new, large Kiox 500 display is also included in all equipment variants.

Pricing and configuration options

The price range of the Moustache The J starts at €5.199 and can reach up to €6.399 depending on the chosen configuration. The most significant price driver is the choice of drivetrain, with the Enviolo internal gear hub adding €800 to the price compared to the Shimano derailleur system. Customers can also choose between a 500 Wh and a 625 Wh battery (an additional €200). A larger battery capacity of 750 Wh is unfortunately not available due to space limitations within the frame.

It is also possible to choose an alternative luggage rack. This is attached to the main frame, so it is protected from shocks and offers more space than the standard carrier. There is also an additional charge of 200 euros for this.

The Moustache J All in practice

In practice, this can Moustache The J will impress above all with its very high level of comfort at a relaxed pace. The suspension allows the bike to glide smoothly over poor bike paths and easy forest roads, which should make many touring cyclists very happy. However, if you venture onto real trails, the bike quickly reaches its limits, partly due to the rigid swingarm that limits performance in these conditions.

The Enviolo hub gear installed in our configuration showed both light and shadow in the test: On the one hand, there was its high level of shifting comfort and the carefree operation in conjunction with the carbon belt. On the other hand, its comparatively small range limits the area of ​​application somewhat, especially in combination with the slightly weaker Performance Line motor, the J runs out of breath quite quickly on steep inclines. In our opinion, the ergonomics of the twist grip are also not optimal. So if you live in hilly regions or are looking for a companion for the mountains, you should choose the cheaper derailleur gear.

The decision for the Bosch Performance Line motor turns out to be the right choice in most situations: Quieter, more harmonious and more natural than the CX, the small difference in performance is then bearable.

We were positively surprised by the very pleasant ergonomics of the bike: Surprised because the frame of the J is only available in one size - the sizes that can be ordered only refer to the length of the installed seat post; But even at 1,87m, the J was still comfortable to drive. However, it should be noted that the step-through of the bike is very high for a low-entry rider. If necessary, you should try this out before purchasing.
