In this year's most unsurprising electric mountain bike news, YT has just revealed that its Core 4 model has returned to its Decoy line-up with full 29-inch wheel and MX options filling the gap between the Core 3 and Core 5 bikes.
The two different wheel size options share much of the same componentry but differ in their suspension setups. The mixed wheel MX model is designed for enduro and bike park action with Ohlins’ top-tier enduro suspension offerings of a 170mm RXF38 M.2 air fork and TTX22 M. 2 coil shock. The trail/all-mountain 29er version gets a RockShox pairing of a 160mm Zeb Ultimate fork and Vivid Ultimate shock.
We've reviewed the previous Shimano EP8-powered Decoy Core 4 model with a 720Wh battery and said, "The reach is short compared to more recently updated rivals, but the playful yet capable Decoy offers great spec for the price and is a blast on everything from flowy to technical trails.".
The new Core 4 bikes join the rest of the Core range in being upgraded to Shimano's latest EP801 motor with the same 720Wh battery. In our tests on other e-MTBs, the new motor is noticeably quieter than the older version, it offers improved peak power output (500 vs 600 watts), and the Di2 equipped Decoy Core 5 comes with Shimano's Free Shift option which lets you change gear without pedaling.
You can see full specs for both bikes below. Pricing for the 29-inch version is US $7,999 / £7,499 / €7,499 / CAD $11,999, while the MX bike will cost you US $7,599 / £6,999 / €6,999 / CAD $10,499. Both options are available to buy now from yt-industries.com
