Trek District 4 Equipped Hybrid Bike 2022
Take to the city streets on Trek's District 4 Equipped Hybrid Bike. It perfectly blends style, fun, and versatility, making it ideal for exploring and commuting, with an Alpha Smooth aluminium frame and aluminium fork, and a stable and comfortable upright geometry. It uses a Gates CDX belt drive system that is far more durable than a standard chain, alongside being super quiet and low maintenance. The 8-speed internal hub creates a super smooth shifting experience, and the hydraulic disc brakes bring confidence-inspiring stopping power into the mix.
The Cruiser handlebar is fitted with ergonomic grips for good control no matter the conditions and the bike rolls on tough Bontrager wheels and H2 Comp 40mm tyres, with the combination well able to handle rougher roads. There's a Dynamo hub up front that that will power your lights. The bike comes packed with useful accessories, including front and rear lights, a kickstand, a rear rack and mudguards, so the bike is well equipped for longer adventures.
