Feb 2020

Price: $2499.00 | Model Year: 2020 A purpose-built fat tire electric bike designed with hunters and campers in mind. The frame and fork are painted with matte Kryptek camouflage to blend into wilderness environments while nearly all accessory hardware is black. Comes with a sturdy rear rack and front basket system, both capable of supporting pannier bags (up to four in total). Extra large 26

Observations
  • A purpose-built fat tire electric bike designed with hunters and campers in mind. The frame and fork are painted with matte Kryptek camouflage to blend into wilderness environments while nearly all accessory hardware is black. Comes with a sturdy rear rack and front basket system, both capable of supporting pannier bags (up to four in total)

  • Extra large 26" x 4.5" fat tires provide traction and float, lower the PSI to navigate on loamy terrain or soft sand. Powerful fat-bike specific Bafang hub motor offers 80 newton meters of torque and is activated quickly and naturally through a rear-mounted TMM4 torque sensor. You get five levels of pedal assist and trigger throttle with full support at all times... Bike can be unlocked to exceed 20mph for off-road use

  • Available in two frame sizes for improved fit. Optional battery capacity upgrade is only $200, and both packs are cross compatible with all other 2020 Surface 604 models. Optional custom fit 120mm wide steel fenders look great and keep you dry. Large color LCD display is intuitive and the button pad is well thought out, it dims when the headlight is activated. Nice 180mm hydraulic disc brakes and 15mm quick release thru-axle

  • No chain guide, narrow-wide chainring, or slap guard here. Front rack is fork-mounted and impacts steering, could dump over when parking or making sharp turns. Straight 1-1/8" headset is less compatible with aftermarket suspension forks. The bike is fairly heavy and the throttle isn't as powerful as the highest pedal assist level, which surprised me a bit
