Giant Dirt E+ 2 2018 Electric Bike

This trail-ready Giant hardtail electric mountain bike's 80Nm torque motor has the power to boost you up hills you would have previously pushed the bike up.

Not to be confused with hybrid-style electric bikes, the Giant Dirt E+ is designed to deliver the pure exhilaration of riding technical trails on a bike that makes the climbs almost as pleasurable as the downhills.

Giant Dirt E+ - the e-bike part

  • Power assist comes courtesy of the Giant SyncDrive Performance 80Nm torque motor, which is the smallest, lightest, quietest and highest power motor Giant have ever fitted to an e-bike
  • The Giant PedalPlus 4-sensor precisely measures the amount of force you're applying to the pedals and delivers a seamless power boost
  • The system combines speed and torque sensors with motor and pedal rotation sensors to produce even power across the entire gear range
  • The result is predictable power that feels totally natural
  • Centre Drive - the motor unit is mounted at bottom bracket level to power the crank (in contrast with most e-bikes which are front or rear hub drive)
  • Most riders find Centre Drive power assist feels more natural than a hub-drive system.
  • With its lower centre of gravity a Centre Drive e-bike feels more stable and balanced than one with a motor integrated with the front or rear hub
  • Giant RideControl LCD - this bar-mounted cycle computer is the bike's speedo/odometer and the motor's on/off switch
  • The RideControl computer makes it easy to set the riding mode as required: standard power assist, sport mode (maximum power assist) or eco mode (maximum run time)
  • The Giant EnergyPak 36V Lithium-Ion 13.8Ahh battery is enclosed inside the frame down tube, so riders you pass won't necessarily realise that you're enjoying 80Nm torque power assistance
  • The battery can be charged in situ or can be quickly removed from its (key-accessed) compartment
  • Giant reckon a fully charged battery will be good for 30-plus miles of power assist in the most challenging conditions (that is a heavy rider, cycling hilly terrain in max power-assist sport mode)

Giant Dirt E+ the mountain bike part

  • The SL-grade AluxX frame is strong and true as we've come to expect from Giant
  • Shimano hydraulic disc brakes enjoy a reputation for being the most reliable
  • Shimano Acera 2x9 Rapidfire shifters and Shimano Deore derailleurs (Shadow rear) deliver slick gear shifts
  • The 24/38 chainset and the 1i-36 cassette offer a really wide range of gears in a simple 2x9-speed format.
  • Maxxis Ardent 27.5x2.4" is a favourite all rounder MTB tyre

Why Giant and E-mountain bikes are a perfect fit

  • Giant have 30 years experience manufacturing some of the worlds' best mountain bikes
  • Giant hybrid electric bikes are among the most reliable we've tested over the past decade
  • Marry these two technologies and you get a trail-ready hardtail mountain bike, turbo-charged with an 80Nm torque central motor, which helps guarantee climbs will no longer be grinds
  • To put 80Nm in perspective, that's around one fifth the torque of the engine of a small car, which will weigh 50 times more than this bike
  • Like every Giant, their Dirt E+ bikes are made from scratch
  • Its AluxX frame is manufactured in-house from the raw aluminium ore, via the smelting process, to the tube shaping, butting, hydroforming, welding and heat treating, to the final highly-protective paint finish
  • Every Giant electric bike is made in their own e-bike dedicated factories
