The Junction Powertrail 27.5” is an electric hardtail mountain bike that features a powerful pedal-assist hubdrive motor that only kicks in when you’re pedaling the bike. The hub-drive motor utilizes a cadence sensor that detects when the pedals are moving and then provides power from the 10.4Ah battery mounted to the downtube. With assistance up to 32 km/h and 5 levels of assistance to choose from, using the LCD display on your handlebar, it is easy to control the amount of power output desired. The Powertrail has a performance-oriented design and is equipped with a durable 6061 aluminum frame, Microshift Advent 8speed shifting system with 42T cassette, Tektro disc brakes, Vaxa E-type suspension fork, performance saddle and alloy stem with Prowheel burner crank. (Note: Bike still operates when battery is discharged).
