GASGAS ECC 4 Review

Sram is aiming to elevate system integration in E-Bikes to a new level with its own Eagle Powertrain engine. For this, the Americans are technically relying on hardware from the German manufacturer Brose and mainly scoring points with innovative software that completely relieves the rider of the need to shift gears through its Autoshift function. If desired, the 12 gears of the Transmission drive can still be manually shifted. As is customary with Brose motors, the Eagle Powertrain motor operates very quietly. The power development is $dynamic and the 9 Nm torque takes the fear out of even the steepest inclines. The average range can become a problem especially for long mountain bike rides.

Carbon frames are rather the exception in the price range of about 7€. With the carbon fibre chassis, GASGAS thus sets clear accents compared to the aluminium competitors. Even nasty descents get smoothened by the good Rock Shox chassis. The thick 38mm stanchions on the fork provide an extra dose of steering precision and performance. The mid-range brakes from SRAM do their job but could be a bit firmer. The power of the four pistons setup is only average. The average shifting components and accessories leave some tuning potential open. For most e-bikers, this should be an acceptable point. With a high Reach value, GASGAS follows the calls of end-users for modern geometries. But the engineers don't lose sight of the remaining geometry measurements. When considering the whole picture, it must be said that the remaining geometry values very good harmonise.
