Super73 Z Adventure Series

The first Super73 here with GEARS: 8 speed rather than the single speed the rest of the range ships, which matters because these are heavy bikes and a single speed leaves you with nothing to pedal once the battery is flat. VEE GRZLY tyres and a non-adjustable fork. 73 lb on the same 480Wh pack, so the 25-35 mile claim comes with 14 lb more to push than a Z Miami. Brakes are Tektro, 2 piston, hydraulic; suspension is front non-adjustable; seat height 31 inches; charge time 5 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.
