Trek Powerfly 5 Electric Mountain Bike 2021
Durable, trail-ready components and a tough aluminium frame ensure the Trek Powerfly 5 Electric Mountain Bike is highly capable off-road and able to adventure further afield with assistance at the ready should it be needed. The Bosch Performance CX motor is compact yet powerful, assisting with up to 250W and 25km/h when some extra support is in order, and the Bosch PowerTube 625 charges fully in a little under five hours. This battery is fully shielded within the frame when in use, and removed easily without the need for tools. The RockShox Recon Silver RL fork provides 80mm of travel, staying responsive whilst also absorbing shocks and bumps on rougher terrain for a smooth ride.
The 1x12 SRAM Eagle components make for snappy shifting and enough gearing options to keep the legs spinning no matter how steep gradients ramp up, and the single chainring also means easier maintenance post ride. The powerful Shimano 4-piston hydraulic disc brakes ensure unwavering descending and confident braking that's rapid and consistent.
