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!


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.

Trek Domane + LT 9 Electric Road Bike in Purple Information

Season : 2021

Brand : Trek

Code : 325782020GLSPURFlip

The Trek Domane+ LT 9 is a high-end carbon drop-bar electric bike designed for roadies who want an authentic road bike experience with an extra boost.

The sleek and efficient Fazua drive system kicks things up a notch when you need it – like riding into a headwind or beating your buddy up a climb – but doesn't drag or hold you back when it's not in use. You also get the high-performance benefits of a 500 series OCLV Carbon frame, road-smoothing front and rear IsoSpeed which absorbs fatiguing bumps and Shimano Dura Ace Di2 components.

The light, fast and efficient Fazua Evation motor and a 250 Wh battery that assists up to 25 km/h. You can easily remove the Fazua drivepack (the battery and motor) from the frame and ride the bike with or without it. Plus, a Fazua controller, Bontrager Aeolus Pro 3V carbon wheels, and hydraulic disc brakes.
The road-smoothing Domane+ frame paired with a streamlined and efficient electric drive system, plus the precision of 2 x 11 Shimano Dura Ace Di2 electronic shifting, is the best of two worlds – a true road bike feel with an additional thrust of power when you want to crush a climb or push yourself to pop off a few more miles.
