Trek Powerfly Sport 7 EQ Electric Mountain Bike 2021
The Trek Powerfly Sport 7 EQ Electric Mountain Bike is a practical, go-anywhere hardtail bike capable of roaming on roads or off the beaten track with a handy 250w assistance at the ready at up to 25km/h. The powerful and compact Bosch Performance CX Motor comes into play when an extra kick is needed to speed up the commute or spin up climbs a little more easily, and the Bosch PowerTube battery is stored neatly within the frame for protection and to preserve a clean outline, as well as leaving room for a bottle cage. As an added bonus, the user-friendly removal of the battery requires no tools.
The RockShox 35 Gold RL 80mm travel fork can be locked out to stay put on smooth surfaces for an efficient ride, and provides shock-absorbing capability on rougher stuff where bumps and rocks prevail. When descending or carving round corners, the TranzX dropper seatpost can be lowered whilst in motion to enable weight to be kept back and low, and Shimano M6120 4-piston hydraulic disc brakes deliver surefire stopping power for confident riding unshaken by tough terrain or attritional conditions. The addition of practical accessories such as the battery-powered lights, kickstand, mudguards and rear rack make this eMTB a useful choice whether commuting or planning a longer day in the saddle. The high-quality Shimano SLX/XT 1x12-speed drivetrain keeps shifting sharp and snappy, providing enough gearing options to keep grinding at bay regardless of how steep the gradients get, as well as making for easier maintenance thanks to the single front chainring.
