Giant Roam E+ Review

Jun 2022

Price: $2750.00 | Model Year: 2022 | A hardtail cross country hybrid that comes in two frame styles, four sizes, and one color: gloss black. It's the most affordable electric bike model from Giant, is sold through dealers, and comes with a two-year warranty plus lifetime frame.

Observations
  • A hardtail cross country hybrid that comes in two frame styles, four sizes, and one color: gloss black. It's the most affordable electric bike model from Giant, is sold through dealers, and comes with a two-year warranty plus lifetime frame.

  • Efficient and quiet SyncDrive motor is a collaboration between Giant and Yamaha. It offers up to 50 newton meters of torque and measures wheel speed, cadence, and pedal torque for smooth natural operation. Optional smartphone app for tuning.

  • Good battery placement with ability to charge on or off the frame. Quality ergonomic grips and saddle, 63mm travel suspension fork with basic preload adjustment, tubeless-ready tires with range of PSI options. Smooth hydraulic disc brakes.

  • Minimalist button pad LED display is durable and easy to use but limited on readouts. Bike does not come with a kickstand, but the dealer might include for free. No lights, fenders, or rear rack stock but plenty of mounting options to add post-purchase. Limited 100 RPM cadence support from motor and no shift detection. Mid-step frame doesn't have bottle bosses.
