Bicycle Guidelines

  • Bikes ride for free with any paying transit riders!
  • Please remember you are responsible for the loading and unloading of your bicycle
  • Remove all loose items not attached to your bike (e.g. bags on handlebars, lights, helmets, etc.)
  • For extra security, lock your wheel to the frame of your bike before the bus arrives. DO NOT lock your bicycle to the bus rack.
  • Each MTS bus can accommodate two bicycles in the rack on the front of the bus. Wait for the next bus if the bike rack is full.
  • Exit the bus through the front door and let the operator know you will be removing your bicycle from the rack
  • Rapid Express routes have lower-storage compartments for bikes  
  • One bicycle is allowed per Trolley car during peak travel times, and two are allowed at all other times. Please stand with your bicycle for the entire trip.

Bus Rack Capacities


  • Traditional bicycles under 55lbs and with wheel sizes from 20-29 inches.
  • Electric bikes with sealed gel, lithium Ion or NiCad batteries
    • You may carry the battery onto the bus if it cannot be secured to the bicycle or it exceeds the weight limit of the rack (55lbs)
    • Electric bikes with liquid lead acid batteries are not permitted


  • Tandem and recumbent bicycles
  • Gas powered bicycles

Inside the Bus

Bicycles are only allowed inside the bus if:

  • It’s a non-motorized, folding bicycle with wheels smaller than 20 inches that can be stored under a seat.
  • The bike rack is full and it’s the last trip of the evening or the frequency of service is more than 60 minutes and the operator determines it’s safe to do so

Bike Lockers

Many transit centers and trolley stations have bike lockers to securely store your bicycle while you commute and work. More bike locker information.
