Four great reasons to buy your bike from Sigma Sports
Sigma Sports has one objective - to help you find your perfect bike. Our friendly, knowledgeable staff ask you a series of questions to understand what type of rider you are and the type of riding you do. We can then identify the style of bike that best suits your needs.
Riding a bike that fits you perfectly will help keep you injury-free and ensure you enjoy riding further for longer in total comfort. We check your measurements on a jig to ensure your optimal set-up.
When you collect your new bike we'll double-check your position and make any micro-adjustments if required. We'll also discuss the controls on your bike as well as maintenance tips.
We offer a free safety check after six weeks or 200 miles, so you can keep riding in confidence. Visit us now in-store to discuss your new bike.
Trek Powerfly FS 9 Equipped Electric Mountain Bike 2022
Comfortable, fast, and efficient - the Trek Powerfly FS 9 Equipped Electric Mountain Bike is highly versatile and suited to various riding styles, whether it's a daily commute or racking up the singletrack miles. With a powerful Bosch motor system and 100mm of rear suspension, the bike combines comfort with efficiency and functionality.
With a durable aluminium frame and high-end Shimano components, the Powerfly is a reliable option to get you from A to B. The downtube neatly conceals a removable Bosch PowerTube 625Wh battery, that packs enough power for all-day riding and is chargeable both on and off the bike. It utilises a compact Bosch Performance CX motor providing 250 watts of climb-crushing power, while the onboard SmartphoneHub computer features a walk-assist setting, making it easy to manoeuvre in off-bike situations.
A 12-speed Shimano Deore XT drivetrain offers a wide range of gears, and powerful hydraulic brakes provide ample stopping power both on and off-road.
This equipped edition focuses on everyday riding and comes pre-fitted with essential ride accessories to improve your ride experience. Mudguards help to defend against road spray and splatter, keeping you dry for the duration of your ride. Front and rear lights help improve visibility in low-light situations, utilising power from the battery to ensure simple charging. A rear pannier rack and stand add daily convenience, while a dropper seatpost adds flow on mixed gradient trail rides.
