This CNC machined aluminum electric mountain bike is an exceptional piece

Using the CNC machining technique, the German brand Alutech has created an aluminum E-MTB frame in just two parts which has the advantage of being lighter than an assembly of tubes welded together. The result is a superb, premium enduro electric mountain bike.

In the bicycle industry, recourse to CNC (computer numerical control) machining is still a rarity due to its complexity and high cost. But a few brands venture there and produce exceptional bikes. This is the case of Alutech, which has just launched an E-Fanes electric mountain bike whose main triangle has been machined from 6061 aluminum in just two parts. The two halves have been welded together using shielding gas which allows working at a lower temperature so that the metal deforms less at the weld point. On the top tube, Alutech succeeded in polishing the weld bead so as to make it invisible.

Besides the very raw and industrial rendering which makes the charm of this E-MTB (it’s a matter of taste), the advantage of this machining technique is that it saves a lot of weight compared to a frame in aluminum welded element by element. In the highest-end assembly offered by Alutech, the E-Fanes displays 21.15 kg on the scale. This is the equivalent of what is found on the most expensive electric mountain bikes with carbon frames. And that’s pretty impressive for a bike with 170mm of travel front and rear.

An ultra elitist price

Of course, the weight saving also owes a lot to the components used for this assembly. The handlebar and wheels (29 inches at the front and 27.5 inches at the rear) are carbon, the brakes are Shimano Xtr and the electronic transmission is a Sram XX Eagle AXS. The suspension is entrusted to a Fox Float 38 Kashima and Fox Float X2 Kashima fork set for the shock absorber. On the powertrain side, Alutech has used the brand new Shimano EP8 engine which weighs 2.6 kg. It is associated with a 504 Wh battery (630 Wh optional). There, connoisseurs already tell themselves that the bill promises to be salty …

And indeed, this E-Fanes is sold for a whopping 16,000 euros! There is no doubt that at this price there is no risk of crossing it often on the trails. Fortunately, the manufacturer offers a version with a less opulent assembly for “only” 7,000 euros and which weighs 1.4 kg more (22.5 kg).
