Trek Domane+ LT Disc Electric Road Bike 2021

Trek’s Domane+ LT Disc Electric Road Bike is a great option for anyone looking to commute more easily, ride hilly routes more enjoyably or just have some of the sting taken out of travel by bicycle. The 500 Series OCLV Carbon frame features internal cable routing, a Ride Tuned seat mast and mudguard mounts. Trek’s IsoSpeed technology adds adjustable compliance to the frame that is controlled by an elastomer so that the ride characteristics can be altered depending on the route or rider.

The Fazua Evation Drive Pack seamlessly adds to the rider’s power up to a maximum speed of 25kph but doesn’t cause any extra drag when coasting or when no assistance is being provided.

The Shimano 11-speed Ultegra R8000 mechanical groupset pairs an 11-34 cassette with a 34/50 tooth chainset to give a very wide range of ratios sufficient for any hill, whilst the Ultegra hydraulic disc brakes provide confidence-inspiring stopping power.
