Giant Explore E+ 4 GTS Review

Nov 2019

Price: $2500.00 | Model Year: 2020 | A hardtail cross country gravel oriented ebike with possibilities for not only light trail riding and off-roading, but as a commuter setup because it offers mounting points for lots of accessories, high quality at a value price point

Observations
  • A hardtail cross country gravel oriented ebike with possibilities for not only light trail riding and off-roading, but as a commuter setup because it offers mounting points for lots of accessories, high quality at a value price point

  • Comes with hybrid tires, suspension fork, rear rack bosses, fender bosses, kickstand provisions, bottle cage bosses, and even extra threaded eyelets on the seat stays for a cafe lock

  • Uses a Yamaha PW series motor with pedal torque and pedal cadence sensing response, very quiet, efficient and reliable, has a nice 9 speed Shimano Deore setup with hydraulic disc brakes, larger 180mm front rotor provides great stopping power

  • No shift detection, no battery integrated lights, minimal display is easy to use and hides the electric aspect of the bike, but may not be for everyone
