Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Trek District+ 4 R10 LS eHybrid Bike in Dark Star

Season:2027

Brand:Trek

Code:81591BLK

District+ 4 R10 Lowstep is a well-rounded city e-bike built for recreation, commuting, and everyday versatility.

Its comfortable geometry and touchpoints pair with a powerful Bosch Performance Line Smart System motor and a 10-speed Shimano CUES drivetrain for smooth support on everything from city streets to weekend paths. Trek began removing high-emission aluminium from manufacturing in 2024, replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike Trek makes, including this one, has made the switch. These e-bikes are designed by riders for riders at Trek's e-bike hub in The Netherlands and assembled in the factory in Saxony, Germany.

Features:

  • Lockable and removable battery: Allows you to lock the battery securely in the frame or remove it when needed for charging flexibility.
  • SP Connect integrated phone mount: A mount on the stem lets you securely attach your phone to your bike and provides wireless phone charging while you ride.
  • Comfort for every mile: Features like the suspension seatpost and ergonomic grips are designed to smooth out your ride.
  • Shimano CUES 10-speed: Reliable, smooth-shifting 10-speed drivetrain.
  • MIK HD rear rack: Supports weight up to 27kg (60lbs), making it compatible with child seats, side panniers, baskets, and pet carriers.
