E-Mountainbike Magazine

The YT DECOY MX CORE 4 is a great companion for all eMTB surfers who love to descend on their rear wheel and don’t need a bigger battery for long days in the saddle. Falling somewhere between the Light and all-round eMTB categories, the DECOY proves that...

  1. capable suspension
  2. high fun-factor on flowing trails and jumps
  3. excellent comfort for long rides
  1. short-travel dropper post
  2. tires with fragile casing
  3. long seat tube restricts choice of frame size

Outdoor Gear Lab

The sleek-looking YT Decoy 29 Core 4 checks nearly all of our boxes and is among the best eMTBs we've tested. With 29-inch wheels, 150/145mm of front/rear travel, and modern moderate geometry, it's a balanced trail/all-mountain bike that performs well on a...

  1. Very competitive price
  2. Awesome build
  3. 3 build options
  4. Versatile and well-rounded
  5. High fun factor
  1. Only 540Wh battery option
  2. Shorter distance range

There are still two versions of the Decoy, where the mixed wheel size option now carries the MX tag and still boasts 170/165mm travel

  1. Looks with ride quality to match
  1. The price has gone up

Review - 2022 YT Decoy MX E-Bike Plenty of range for plenty of good times.

  1. Eats up the steep, nasty downhills
  2. Battery life and performance
  3. FOX Factory suspension is a solid performer
  4. Parts to price/Value
  5. Faster is more fun
  6. Shimano E-Tube app
  1. Struggles on techy climbs
  2. Not an easy jumper
  3. Sluggish in sprints
  4. Voluminous, EXO rear tire

Last year YT released its Decoy 29 eMTB, a steeper-angled option to its original e-mullet Decoy first introduced in 2017. The original 29/27.5” Decoy was Enduro focused and branded toward young talented rippers with a tagline about replacing the shuttle....

The YT Decoy 29 Core 3 remains a force! In terms of development, the YT Decoy 29 has been around for a while now and may have gathered some dust for some. However, in our opinion, counting it as old and outdated would be a mistake because...

  1. Modern geometry - fast and precise to ride
  2. High-quality processed carbon frame with a stiff rear end
  3. Unique design with high recognition value
  1. Rubber grommets at the cable entries are shifting

  4. No local distributor nearby in case of problems

Here’s the YT Decoy Shred: mid-priced mullet bike that comes with a coil-sprung Fox DHX2 shock that’s guaranteed to make it the life and soul of any party

  1. Shreds every trail
  1. The saddle’s a little firm


Alan Muldoon

The carbon YT Decoy Elite is a divertingly sleek enduro bike that just happens to have a motor

  1. Standout in every regard: looks, finish, ride quality and value.
  1. If you’re upsizing for increased reach, you’ll need a lower-rise bar, or at the very least flip the stem. Rear end collects mud.
