The RT-B-A18 is an 18-seater electric shuttle bus bridging the RT-B-A14 and RT-B-A23 — delivering mid-size, zero-emission mass transit for large campuses, corporate parks, and institutional facilities.


The Roots EV RT-B-A18 is an 18-passenger electric shuttle bus positioned between the RT-B-A14 and RT-B-A23 in the Roots EV bus range, built for operations that have outgrown a 14-seater but don't yet need full 23-seater capacity. It is designed for large IT parks, university campuses, industrial complexes, and township developments where efficient mass transit of staff, students, or residents is a daily operational requirement. The RT-B-A18 pairs a high-torque 3-phase AC induction motor with a high-current BLDC controller to handle the demands of 18-passenger operation across varied campus terrain, while the large-capacity LFP lithium battery pack ensures sufficient range for full-day duty cycles without a mid-shift recharge. Passenger comfort is prioritised throughout the spacious interior, with comfortable seating, generous headroom, and proper ventilation for India's varied climate conditions. The smooth, vibration-free electric ride is a marked improvement over diesel alternatives, reducing driver fatigue and improving the passenger experience across repeated daily shuttle routes. Built for Indian operating conditions, the RT-B-A18 uses robust components rated for the heat, dust, and varied terrain found across the country. It meets all relevant safety standards and is backed by Roots EV's pan-India service network.
