The top of the Super73 range and the only one with both full adjustable suspension AND 8 speed gears, on the 960Wh pack for 45-55 miles. At $3,895 it is the most expensive bike from this brand on the site; against the R Brooklyn SE the $300 buys the gears and costs 5 lb. If a single speed at 88 lb sounds like a bad day when the battery dies, this is the one to look at. Brakes are Tektro, 4 piston, hydraulic; suspension is front and rear adjustable; seat height 32 inches; charge time 6-7 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.
