Our take on the Gravity eBullseyeMonster EaglePro Mid Drive Electric Fat Bike

The Gravity eBullseyeMonster EaglePro is a fat-tire electric bike built around a Bafang M600 mid-drive motor rated at 500W and 120Nm, with assist up to about 28 mph. It pairs a hydroformed 6061 alloy frame with a RockShox Bluto air fork, Shimano hydraulic disc brakes and a SRAM SX Eagle 1x12 drivetrain with an 11-50T cassette. The 26x4.9 Big Daddy tires on 80mm rims make it a true soft-surface bike. Its best new price is $2,456 at Bikesdirect.com as of November 3, 2026, the only price seen since October 31, 2026, so there is no lower recent price to wait for.

Best forRiders who want a torquey mid-drive for steep climbs and soft groundFat-bike fans riding sand, snow and rough trailsBuyers comparing against pricier brand-name e-fat bikesRiders who want a wide 12-speed gear range for mixed terrain
Pros
  • 120Nm mid-drive torque is strong for climbing and loaded riding
  • Mid-drive layout usually gives better range and balance than a hub motor
  • RockShox Bluto air fork with lockout and 150mm thru axle
  • SRAM SX Eagle 1x12 with 11-50T cassette gives a wide gear range
  • Shimano hydraulic disc brakes with 160mm rotors
  • Bundled pedals, throttle, kickstand and upgraded sprung saddle
Cons
  • Only one store lists it, so there is little price competition
  • Heavy fat tires and 80mm rims slow acceleration and drain battery faster
  • 160mm rotors are modest for a bike this heavy at speed
  • SRAM SX Eagle is an entry-level 12-speed group
  • No rear shock, so it is a hardtail on rough ground

Questions and answers

Is the Gravity eBullseyeMonster EaglePro worth it?
At $2,456 at Bikesdirect.com as of November 3, 2026, you get a 120Nm mid-drive, air fork and 12-speed drivetrain that cost much more on brand-name e-fat bikes. It is a strong value if you can handle the weight and do your own setup.
How fast does it go and how far on a charge?
Gravity rates assist up to about 28 mph. Range depends on rider weight, terrain and assist level; fat tires and a heavy frame cut range, so expect noticeably less than a comparable skinny-tire e-bike.
Is it good for sand and snow?
Yes. The 26x4.9 tires on 80mm rims are made for soft surfaces, and the 120Nm mid-drive helps keep momentum. Run lower tire pressure for float, and expect slower steering on hardpack.
What comes in the box?
The bike ships with pedals, an electric throttle control, an e-bike-rated kickstand and an upgraded Mango Ultra Cruiser sprung saddle. Battery and charger are included as part of the e-bike build.
How does it compare with a hub-drive fat bike?
The mid-drive motor drives through the gears, so it climbs better and is usually more efficient than a hub motor. Hub-drive bikes are often cheaper and simpler, but they feel less balanced on technical terrain.
When is the best time to buy?
The price has been flat at $2,456 since October 31, 2026, with only one store listing it. Watch for holiday sales, but there is no recent lower price to wait for.
