Business in the front, party at the back. That's how the combination of a 29-inch front wheel and 27.5-inch rear wheel is often referred to. The Decoy CORE 4 MX also has such a wheel setup. Paired with plenty of suspension travel, it wants to provide downhill fun in particular.
In the automotive and motorcycle world, Japan has always had a reputation for being a breeding ground for excellent engines. Shimano is doing its utmost to live up to this reputation in the e-bike world with the EP8 engine. Even angriest ramps the Shimano motor easily climbs up well Although the EP8 isn't the strongest when it comes to maximum power, it still has its advantages.. The Shimano EP8 provides a well-rounded riding experience with a gentle power delivery. The short range unfortunately limits the tour radius quite significantly.

At a glance

The most importanten ratings of the Decoy CORE 4 MX in comparison to the competitor bikes of following categorie: (7000) .

At the chassis, YT were generous and gave the Decoy CORE 4 MX a golden shine Kashima chassis from the house of Fox with 170 mm of travel at the front and 165 mm at the rear. Setup-Nerds can squeeze out the maximum performance from the chassis thanks to the many setting options. The thick 38mm stanchions on the fork provide an extra dose of steering precision and performance. At the brakes, YT instals upper class brakes with four pistons and 2 millimeter rotors from SRAM. The shifting and the rest of the components are always in the shadow of the engine when it comes to electric mountain bikes. Nevertheless, YT doesn't skimp here and instals very good components. The moderate head tube angle provides a good compromise between stability and agility when going downhill. The reach is also right there in the middle ground. The bottom bracket is high, which costs handling points. This tends to make the rider stand on the bike. On other EMTBs it feels better integrated. Short chainstays and and a slack seat angle make the front end light in steep climbs. To keep the front wheel on the ground, you need to consciously lean forward. With its 21,7 kg, the Decoy CORE 4 MX is one of the lighter E-bikes. The competition is often significantly heavier.
