Made for cruising, the Marin Sausalito ST is an urban, electric bike that's as suited to your daily grind as it is your weekend adventures. The Sausalito ST has a powerful Shimano STEPS electric motor to boost you up those hills and get you where you're going cool, comfy and composed. 650b wheels and wider tires smooth out the bumps and there are heaps of options for fenders, frame bags and lights making it the perfect customizable commuter. Whether you're in a rush or taking in the scenery, the Sausalito will get you there looking and feeling fresh. 
The Marin Sausalito ST is the step-through version of this bike, built with a lower frame top tube than the standard version. Many riders find step-through frames easier to hop on and off and they're particularly suited to riders who need to mount/dismount their bike frequently, for riding with heavy bags and gear where slow-speed balance can be an issue or for those with reduced mobility.
