Benno Bikes Boost Performance Step-Through e-Bike. Designed as a utility-focused option for commuting, cruising, and lifestyle activities, the Boost Performance Step-Through e-Bike is among our top picks for getting to work and hitting the farmers market on the way home. It provides pedal-assist power with an integrated Bosch Electric Drive system, delivering a range of up to 85 miles. With a wide range of compatible attachments (sold separately) we also use this bike for weekend fun, whether taking our little one for a joy ride with the compatible kid carrier or strapping on our surfboard for a trip to the beach. This Step-Through version provides a lower top tube than the standard version that’s perfect for smaller riders. Thanks to its adjustable seat and one-size-fits-all design, Benno confidently recommends this bike to riders ranging from 5’1″ to 6’3″.
