More from Seatylock

From Viking Chain Locks to Foldylock Compact Cases, U-lock mounting brackets and more, the Seatylock brand offers anything and everything a security-conscious cyclist needs.


Funded by a successful Kickstarter campaign in 2014, Seatylock is a startup created by four friends in New York – a manufacturer, a product designer, a lawyer and an MBA grad. Driven by their love of urban cycling and a concern about bicycle and saddle theft in the city, they combined their skills to create a comfortable, ergonomic bicycle seat that turned into a super sturdy one-meter-long lock. The team continues to work on alternative, new lock designs, as they believe many of the innovative locks on the market aren’t innovative or strong enough.
