Trek Allant+ 8S Review, 2024

Feb 2024 · John S. Bozick

This comfortable commuter combines cool tech with a responsive, dialed-in feel. As a legacy brand with nearly 50 years of experience, Trek is a well-established company trusted by riders worldwide. Based on the experience we had when we reviewed the FX+ 2 city e-bike, we had high expectations from the brand’s Allant+ 8s commuter. We

Highs
  • Aside from the increased speed, it’s hard to tell you’re riding an e-bike thanks to the impressively smooth yet powerful 250W Bosch Performance Line Speed mid-drive.

  • Quick access to navigation, music, contacts and more when using your phone as a display; the Bosch system pairs with the brand’s COBI.BIKE app.

  • Feels planted and stable – yet nimble – with 27.5”x2.4” tires, a rigid fork, solid construction, and an overall weight of 57 lbs.

  • Capable of extended rides thanks to its 36V, 625 Wh battery. A supplemental range extender battery can also be added for more miles.

  • A truly refined and elevated feel that comes as a benefit of being a Trek product.

  • Keeps up with traffic more easily as a Class 3 e-bike with pedal assist up to 28 mph.

  • Pedals effectively on hills and at high speed thanks to a versatile 11-42T cassette.

  • Great modulation and responsiveness from the 4-piston Tektro Orion hydraulic disc brakes.

  • Four levels of pedal assist for a streamlined, easy to use system.

Lows
  • We like the Bluetooth functionality and COBI.BIKE app, but the bike’s integrated universal phone mount felt flimsy. We’d prefer something more durable.

  • We appreciate the visibility granted by the pulsating tail light, but we challenge Trek to include brake lights on the next iteration of the bike.

  • The Allant’s lights are always on, though servicers of Bosch systems can adjust this setting.

Observations
  • A great all-around electric bike that's capable on city streets and light trail, it replaces the Trek Dual Sport+ from earlier years. Proven Bosch Peformance Line CX motor with shift detection. The high-step frame has mounts for adding a second battery pack (Bosch Range Boost) to double capacity, but the step-thru does not

  • Durable and quiet plastic fenders, sleek and sturdy Racktime rear rack, bright integrated lights with side windows to maximize visual footprint, reflective tires and high-contrast paint accents keep you seen.

  • Excellent weight distribution, clean integrated battery pack with Trek RIB casing for easy handling (because it has a built-in handle). Powerful smooth 180mm hydraulic disc brakes. Highly adjustable coil spring suspension fork with lockout, preload, and rebound

  • The bike only comes in one color, but each frame type has three sizes for optimal fit. Trek has a vast network of dealers and is recognized as one of the "big three" ebike manufacturers. The Bosch Purion display is a bit limited but leaves plenty of room for Trek Blendr stem mounted accessories. Bosch CX motor is powerful, but louder than some competing products
