Trek Powerfly 7 Electric Mountain Bike 2022
Tremendously versatile, the Trek Powerfly 7 Electric Mountain Bike helps the rider conquer any off-road trail. The Bosch Performance Line CX motor combines with its PowerTube 625Wh battery to deliver a reliable, long-lasting and natural feeling pedalling boost when the terrain is technical and energy-sapping. The motor is neatly integrated into the frame’s silhouette to grant a clean aesthetic, and the battery is hidden inside the downtube, completely shielding it from impacts and inclement weather. When the battery is flat, it can be easily removed from the frame, plugged in and recharged from flat within hours. Controlling the motor’s assistance level while riding is simple, thanks to the handlebar-mounted Kiox unit. This system includes an easy to read display that shows key ride metrics such as speed, distance and time and also activates the bike’s built-in anti-theft device.
The Alpha Platinum aluminium frame is cold-extruded and butted to afford maximum strength, and its top tube is shaped according to the bike's size to guarantee comfortable standover clearance for smaller riders. Additionally, the bombproof, rugged wheels are also bike-size specific, with 27.5” rims featuring on the smaller sizes and 29” on the larger offerings to ensure balanced handling whatever the rider’s stature. These wheels are shod with wide, tubeless-ready tyres that afford traction, control and reliability.
A RockShox fork affords plush suspension over rough terrain, while a Shimano 12-speed drivetrain grants super-smooth gear shifts and a wide range of ratios for varied topography. Four-piston hydraulic disc brakes stop with aplomb in all weather conditions, and a dropper post bestows extra confidence on fast, winding downhills.
