Our bio

Trek Bicycle Lake Grove is your destination for the latest products from Trek and Bontrager, 24-hour service and tune-ups for bikes of any brand, and professional bike fit services. We’re conveniently located on the outskirts of the Smithaven Mall in Lake Grove where we’re proud to service the communities ranging from St. James all the way out to the North and South fork of Long Island. We’re also lucky to be located near some awesome places to ride, like Laurel Ridge Preserve, Glacier Ridge Preserve, and Manorville Hills. Our team is passionate about getting more people on bikes, which is why we offer maintenance clinics of all kinds, road and trail group rides, mountain bike trail-work days, and Trek women rides. We’re also proud to support the local cycling community through fostering a relationship with Suffolk Bike Riders Association (SBRA) and Concerned Long Island Mountain Bicyclists (CLIMB). Whatever your experience level and however you like to ride, we welcome you to stop in, meet our team, and see what we have to offer. We can’t wait to ride with you!
