Berria has made a big bet on this new bicycle. Here’s why: both the trends in the gravel biking sector and those in road cycling are moving toward extremely lightweight carbon frames that don’t differ much from “muscular” bikes, supported by motors that provide light power assistance (known as “light” motors) to offer minimal power while maintaining a very natural riding feel.

Well, Berria’s new Mistral Essential isn’t quite like that. They’ve created an excellent aluminum frame that, admittedly, hasn’t managed to reduce weight compared to a carbon frame, but it has lowered the price: this Mistral Essential is available starting at 3,499 euros. It’s worth noting that there was already a Mistral in the catalog, one with a carbon frame and a Bosch Performance Line SX motor.

Continuing with the new Mistral Essential: it’s equipped with an Avinox M2 motor that is anything but lightweight in terms of power output—1,100 watts with a maximum torque of 110 Nm, which can reach up to 125 Nm in boost mode.

The frame is versatile

Berria has been looking for a versatile and efficient bicycle that doesn’t have to compete with either e-gravel or more sporty e-road bikes. This Mistral Essential, which comes in models for both approaches, is an excellent bike for riding, giving riders the peace of mind that a highly powerful motor is backing them up—allowing them to undertake long trips with complete confidence.

Moreover, gravel bikes are also being widely used in cities, so a powerful engine will allow us to navigate the big city safely: the black asphalt of cities is also a possible setting for the new Mistral. Its aluminum frame features enough threads to attach various accessories. The wheelbase measures up to 50 mm.

Both models feature the use of various carbon components, such as the stylish fork or the saddle stem (Avantforce Tibia), which has a crossbow-style design that helps absorb road irregularities. It should be noted that the weight of the new Mistral Essential has increased due to the use of aluminum as well as the installation of a powertrain like the Avinox: the bike now weighs 17.7 kg.

Motor: abundant power

The Mistral Essential won’t have any issues on uphill terrain: the Avinox M2 motor delivers up to 1,100 W of power with a maximum torque of 110 Nm, which can reach 125 Nm in boost mode (for up to 60 seconds).

A 600 Wh battery (non-removable), the Avinox FS600, has been installed. We believe it’s more than sufficient for the Mistral Essential’s design. On the top tube, there’s a surprise: Avinox’s DPC100 display, which is color-based and very comprehensive. We call it a surprise because it’s also common these days not to equip e-Gravel or e-Road models with any display that indicates they are electric bicycles...

Gravel and road models at the same price

The new Mistral Essential models are available in gravel and road versions, both priced at 3,499 euros. The main difference between the two lies in the tires installed (gravel or road), as all other components, including the SRAM single-speed transmission, are identical. As typical Berria bikes, various components can be customized through their website, with an additional cost associated with that.

An additional model released on the market with Avinox, and in this case it holds special significance because, on one hand, there was already a Mistral in Berria’s catalog featuring a carbon frame; the easiest option would have been to keep the design and engine while using an aluminum frame.

On the other hand, it’s significant because gravel bikes equipped with Avinox engines are starting to appear. Could this mark a shift in trend? For more details: Berria Mistral Essential
