Price: $3599.00 | Model Year: 2020 | 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

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
