HC Bicycle Shop is a bike shop on the first floor of 661 Yishun Avenue 4, selling bikes and doing bicycle repairs, with inner tube replacement and foldable bikes among the common jobs. Repairs are the main draw. One customer came in only for an inner tube, and the owner's helper also removed a broken screw with patience, checked the brakes, and adjusted the stand and gears. Shoppers who bought a bike in person say the staff set it up properly before they left, and that the owner explained how to look after a foldable bike and how often it needs maintenance. Customers describe the staff as patient, friendly and knowledgeable. Buying in person is what they praise most, compared with ordering online. The nearest other bike repair shop, 7cycleworkshop, is 0.5 km away and rated lower. The address is 661 Yishun Avenue 4, #01-427, Singapore 760661.
