An A-Series moto frame at 88 lb on a 520Wh pack, and Super73 quote the consequence plainly: 20 miles. That is the shortest range on this site by some distance, and the honest reading is that the modular second battery is not really optional if you ride more than a neighbourhood loop. Hydraulic brakes and a rigid frame, single speed, 250 lb rider limit. Brakes are Super73, 2 piston, hydraulic; suspension is rigid; seat height 30 inches; charge time 5-6 hours; horn fitted. SENSOR SOURCE: Super73 publish the sensor type on no product page. Their own guide at https://eu.super73.com/blogs/guides/cadence-and-torque-sensor says "The SUPER73 Z-MIAMI, ZG, and ZX are equipped with a cadence sensor. The rest of the SUPER73 models have a torque sensors." Super73 describe the pack as "UL2271 Compliant", which is a battery claim and a weaker word than certified; there is no UL 2849 system claim.

| As the maker states it | Batteries described as UL 2271 compliant (compliant, not certified) |
Safety certification: UL 2271: battery only. Super73 states: “Batteries described as UL 2271 compliant (compliant, not certified)” (source). That is the manufacturer’s own claim, not something we verified, you can check a specific model in UL’s Product iQ database. Why this matters.
