2019 BULLS E-STREAM EVO AM 4 27.5+ Review

Nov 2019

Price: $6299.00 | Model Year: 2019, 2020 | A full suspension all mountain bike with plus size tires, hydraulic disc brakes, high capacity battery, and a lightweight Brose S Mag mid-drive

Observations
  • A full suspension all mountain bike with plus size tires, hydraulic disc brakes, high capacity battery, and a lightweight Brose S Mag mid-drive

  • 27” x 2.8” plus sized tires provide increased traction, great float, and improved comfort while remaining stiff and responsive because of thru-axles and Boost hub spacing

  • Ergonomic locking grips from Ergon, remote seat post dropper from Kind Shock, quad piston front and rear hydraulic disc brakes from Magura, 11-speed Shimano XT drivetrain with Shadow Plus clutch

  • Additional cost if you want the lights and bottle setup, $170 for the lights, and $46 for the bottle, this seems kind of high, especially since the bike is already at $6,299, optional rear light inhibits full range of dropper seat post
