The Rail+ 5 is an alloy enduro e-bike that delivers huge value for big adventures. Its rugged Alpha Platinum Aluminium frame partners with a RockShox Deluxe Select+ RT shock and Psylo Gold RC fork (160 mm rear/front) to charge through the roughest terrain on the mountain. A Shimano Deore 12-speed drivetrain and 4-piston MT4100 brakes deliver clean shifting and brake modulation that doesn't break the bank. It's topped with a TranzX dropper post and tubeless-ready Bontrager Line TLR 30 wheels for charging into anything.
