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

Hassle free returns

We want you to be completely happy with your purchase. If for any reason you're not satisfied, we accept returns within 30 days of the date of delivery, provided the item is unused, in its original condition, and returned with all original packaging and tags intact.

To initiate a return, please contact our customer service team who will provide you with a returns authorisation and instructions on how to send your item back to us. Please do not return items without contacting us first, as this may delay the processing of your refund.

Return postage costs are the responsibility of the customer unless the item is being returned due to a fault or an error on our part, in which case we will provide a prepaid returns label. We recommend using a tracked service when returning items, as we are unable to accept responsibility for parcels lost in transit.

Once we have received and inspected your return, we will process your refund within 5 working days. Refunds will be issued to the original payment method used at checkout. Please note that original delivery charges are non-refundable unless the return is due to a fault or error on our part.

Certain items are exempt from our standard returns policy. For hygiene reasons, items such as socks, gloves, and base layers cannot be returned once opened unless they are faulty. Gift cards are also non-returnable.

For safety reasons, helmets and other protective equipment cannot be accepted as a return or exchange unless covered under warranty. If you believe any item is faulty or covered under warranty, please contact our customer service team with details of the issue and supporting photographs where possible, and we will assess this on a case-by-case basis and look to offer a repair, replacement, or refund as appropriate.

Giant Defy Advanced E+ Elite 2 25km/H eRoad Bike in Mercury

Season:2026

Brand:Giant

Code:6400002Mercury

With its smooth-riding composite frame, lightweight battery, and new SyncDrive Move Plus integrated rear hub motor, the Defy Advanced E+ is the ideal choice for performance-minded road riders who want to tackle steep hills, maintain higher speeds, and experience road riding with no limitations.

Features:

  • SEAMLESS POWER
    The SyncDrive Move Plus motor is integrated into the rear hub and delivers 30Nm of power (equivalent to 75Nm with a mid-drive motor) directly to the rear wheel. Weighing just 1.7kg, it’s specially tuned for the pedaling pattern of performance road riding, with minimal energy loss and more torque at higher speeds. The result is a natural feel when accelerating or maintaining steady power at speed, and no motor drag while freewheeling or coasting.
  • SYSTEM INTEGRATION
    The down tube integrated EnergyPak 400 battery system weighs just 2.3kg and is purpose-built for the specific needs of E-bikes. A top tube mounted RideControl Go button makes it quick and easy to turn the E-bike on or off and change power modes. Smart Assist technology uses three sensors to precisely measure the power being applied to the pedals and produce just the right amount of support for a smooth, natural ride experience. All models feature SRAM wireless electronic shifters and an integrated taillight.
  • PURE ROAD PERFORMANCE
    A lightweight composite frameset and high-performance components including a D-Fuse seatpost and handlebars for compliance, integrated WheelSystems with tubeless tires, and a wireless electronic drivetrain all add up to a smooth, efficient ride quality that mirrors the award-winning performance of the Defy endurance road bike range.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
