Electric Bike Review
Trek Domane+ SLR 9 eTap Review

Nov 2022

Price: $12999.00 | Model Year: 2023 | An ultra light weight 28.5lb electric road bike with endurance comfort geometry and iso speed vibration dampening seat post interface. The first ebike to feature Trek's OCLV carbon fiber. Available in five colors and seven frame sizes.

Observations
  • An ultra light weight 28.5lb electric road bike with endurance comfort geometry and iso speed vibration dampening seat post interface. The first ebike to feature Trek's OCLV carbon fiber. Available in five colors and seven frame sizes.

  • This particular build uses top of the line SRAM components with a 1x12 drivetrain, flared drop bar, and 40c wide gravel tires. Alternative builds offer narrower road tires and a 2x12 Shimano drivetrain. SRAM Red electronic shifting and 160mm hydraulic disc brakes.

  • Hidden fender mounts add utility, integrated top top tube display panel works well and is easy to read, optional smartphone app provides motor tuning settings, optional range extending 160wh bottle shaped battery pack provides 40% more range and off-bike charging.

  • Excellent control pad button placement on left and right hood. Includes 4 amp fast charger despite having a lower capacity 360wh battery. Main battery not removable for charging and storage. Seat post is a proprietary shape so upgrade options are limited.

Trek Domane+ SLR 6 2023 first ride review: how discreet can an e-road bike be?

Oct 2022 · Martin Staffa

With a new TQ-HPR50 mid-drive motor hidden inside its frame, the Trek Domane+ SLR 6 2023 goes e-ncognito, promising to deliver an authentic road bike feeling despite its electric motor. But does it actually work?

Highs
  • Balanced weight distribution and good handling

  • Excellent motor integration

  • Hardly perceptible noise level

  • Generous tire clearance

  • Mudguard mounts ensure good everyday suitability

Lows
  • Disproportionately thick down tube looks awkward
