AMSTERDAM (BRAIN) — Gates Carbon Drive and Enviolo have collaborated on a drivetrain for high-speed e-bikes, also called speed pedelecs, which require taller gearing to achieve speeds of up to 28 mph.
With input from Gates, Enviolo re-designed its stepless and automatic shifting groupsets to allow product managers to spec a 22-tooth Gates rear sprocket on all e-bike categories–city, trekking, sportive, cargo and commercial. Due to clearance limits, bicycle manufacturers were previously limited to using a 24-tooth Gates sprocket with a larger front sprocket to achieve the higher gear.
The new product also eases fitment issues for front sprockets mounted on mid-drive motors, enabling the use of a smaller front sprocket to improve frame clearance on models equipped with larger tires and with shorter chainstays.
“Gates is committed to expanding the e-bike market and facilitating the adoption of Gates Carbon Drive belt systems across all bicycle market segments by developing strategic applications and working directly with manufacturers to develop new products that serve consumers and bicycle brands,” said Chris Vasiliotis, global product engineering manager for Gates Carbon Drive.
“The combination of the Gates Carbon Drive system with an Enviolo internal gear hub, which creates a quiet and very low-maintenance solution …read more
