Chain problems
Gets worseThrottle-heavy riding stretches Super73 chains fast, and single-speed drivetrains hide the wear until the chain skips on the sprocket. Check every 500 miles.

What goes wrong on Super73 e-bikes
Super73s are ridden hard, often by younger riders, and it shows in the repair mix: bent rims and blown tubes from curb hits, brake pads gone in months, and stretched chains from throttle-heavy riding. The moto-style tires are a specialty size worth booking ahead for. Electrically the platform is robust, but aftermarket controller and firmware modifications are common and cause many of the faults we see. Un-modified bikes are far more reliable. Battery packs are large and expensive; diagnosis before replacement matters.

Tire replacement
MaintenanceSuper73's moto-style 20x4-plus tires are a specialty size. Mention your model when booking so the right tire is on the van; standard fat-bike tires do not always fit the rim profile.
