North Superior Street in Appleton is where Chain Reaction Cyclery, Niki’s shop, does business — and her hands-on approach defines it. She once stayed late to change an inner tube so a rider would not miss a ride, and the staff mixes solid knowledge with honesty and a sarcastic streak the regulars enjoy. The service bench ranges from quick tube changes to full custom builds: an ancient Schwinn got a tune-up, a recumbent trike got a custom-built rim and tire, and one rider moved from a hardtail into a Transition Sentinel with the shop’s guidance. E-bike work is part of the bench’s range, and a Bianchi gravel bike found its match through a conversation about riding style. The brand lineup includes Fuji, Rocky Mountain, Bianchi, Biria, and Breezer, and the advice stays straight — no upsell, no jargon. The address is 818 North Superior Street on Appleton’s north side, reachable at (920) 733-1141. For cyclists who want a shop with personality and a mechanic willing to stay late to keep them rolling, Chain Reaction fits.
