2025 Forestal

Cyon Diode PRO

Andorran brand Forestal’s trail-focused SL ebike

Read Review

A newcomer on the scene, young upstart Forestal is aiming to mix it up with the best electric mountain bikes on the market. And in this test we take a look at its trail bike offering; the Cyon against three of its peers (see below). Specialized S-Works Turbo Levo SL  Trek Fuel EXe Pivot Shuttle SL Need to know Lightweight e-bike with 150mm travel, front and rear 60Nm torque from the Bafang-built EonDrive motor, paired with a 360Wh battery Carbon frame with asymmetric reinforcement strut, single pivot swingarm and linkage driven shock Full colour display integrated into top tube gives GPS mapping and enough data to make your head spin With only three models, the Forestal range is pretty easy to navigate. It’s an e-bike only brand from Andorra where the Hydra is the full-power bike, the Siryon is the 170mm travel mid-power bike, which we’ve already tested, and the Cyon is essentially a 150mm trail bike version of the Siryon.  Forestal then splits each platform into tiers, lowest to highest as follows: Halo, Neon and Diode, so the Cyon Neon tested here is the mid-range, mid-powered, mid-travel model. Simple, right? It shares the exact same full carbon frame as the other two bikes in the Cyon lineup, a frame that’s designed around a powerful 60Nm Bafang-built EonDrive motor (1.95kg). Geometry and sizing is modern for a 150mm travel 29er trail bike, bar the 480mm seat tube length that limits the amount of drop you can run on your seat post. Also, it rides a little high in its travel and is the only bike in this test without geometry adjustment. So we’d like to see Forestal add a low geometry setting to bring its vital stats a little closer to the Trek Fuel EXe, which has arguably the best geometry of the mid-power bikes we’ve tested.  With a bright, clear display nestling in the top tube the user interface on the Forestal is certainly hi-tech, but takes longer to boot up. It has GPS for maps and tracking, so if your bike gets stolen you should be able to find it as easily as tracking down your phone. The handlebar remote offers five modes – off, walk, eco, sport, race and nitro.  Powering all of the electronics on the Cyon and tucked neatly inside the down tube is a 360Wh battery (1.8kg). Forestal will also offer a 250Wh aftermarket range extender when it’s ready, bringing the total battery capacity to 610Wh. And while that sounds like a lot of juice, the Forestal is one energy hungry bike. As such, it fared worst in our range test, only just offering an hour of ride time before the lights went out. So you’ll need the range extender, once available, if you plan on venturing further afield.   Which raises an interesting dichotomy. The 250Wh range extender is going to weigh roughy 1.5kg, which will bring the total weight of the bike close to 20.5kg. So almost the same as the lightest full …Continue reading »

The Forestal Cyon Halo is a lightweight emtb from Andorra. The size Large testbike weighs in at 18.8 kg without pedals. Many emtbs run a 160 mm travel fork, the Cyon comes with a 150 mm fork. Going down just 10 mm usually means we’re dealing with a less agressive bike. Watch our video review, or keep reading below. Specs The Forestal Cyon Halo comes with the Rockshox Pike Select fork.
