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.

Giant - Reign Advanced E+ 1 Electric Mountain Bike in Mercury/Carbon Smoke

Season:2026

Brand:Giant

Code:6461001MercuryCBNSMK

The Reign Advanced E+ is designed to be the best descending E-MTB ever.

From the bottomless feeling Maestro suspension with 170mm of rear travel (and a 180mm fork) to the punchy new SyncDrive Pro 3 motor and its lightweight, stiff, and ultra-adjustable composite frame. This bike includes a titanium skid plate, robust frame protection, and an innovative bash-guard with an elastomer damper, so you can ride with confidence on the most rugged, technical terrain.

Features:

  • DOMINANT ON DESCENTS - Featuring a modified Maestro suspension system with a new integrated lower link and 170mm of rear travel paired with a 180mm fork, this is the best descending E-bike ever from Giant. Maestro’s floating pivot design means it is always active and efficient under pedaling. Its progressive leverage curve makes the rear shock easy to compress at the top of the stroke and super-supportive near the end range, producing a plush, bottomless feel that uses every bit of its travel. The result is unmatched confidence and control for big hits, steep drops, and technical rock gardens.
  • LIGHTWEIGHT YET POWERFUL - Upgrading from a 36-volt to 48-volt system results in better performance with reduced heat and energy loss. With 90Nm of torque and 800 watts of peak power, the new SyncDrive Pro 3 motor lets you sustain a high torque level, even at higher pedaling cadences, so you feel powerful, consistent support in any riding situation. The added power combined with a lighter composite frame and overall weight of just 22.3kg (size medium) means the Reign E+ Advanced packs a punch when you need it most. The 48-volt system also produces less stress on the EnergyPak 560 battery, which has a nearly endless lifespan of up to 2300 charge cycles.
  • PREMIUM PROTECTION - Designed to shred hard and take a beating, the Reign Advanced E+ features a tough, dual-density battery cover that doubles as a full-length protector on the underside of the down tube, perfect for chairlifts, trailers, or pickup truck shuttles. A new integrated skid plate protects the motor with corrosion resistant titanium that is twice as strong as aluminum. With less friction, the skid plate also helps keep you from getting hung up on rocks, roots, or other obstacles. Finally, a unique MRP active bash-guard, with an elastomer damper and suspended design, gives you unmatched chain and chainring protection.

    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.
