Description
TRA 4
The TRA 4 is a hardtail eMTB that’s at home on gentle trail centers and flowing blue grade trails. Great for beginners, the aluminum frame is equipped with a 120mm RockShox fork to track through the rough stuff with ease. Reliable and dependable, the mid-mounted Yamaha PW-S2 motor aids traction when cornering, while the 630Wh battery goes the distance. The TRA 4 is available in both 27.5” and 29” wheel sizes, plus two colorways.
