SUPER73 S2: Class 2 electric bicycle

01 / What it is

The machine, in the manufacturer’s own terms

SUPER73 calls the S2 (CORE / SE / LE (2026 U.S. factory Class-2 configuration)) a Class 2 electric bicycle. The manufacturer programs and labels it as a Class 2 electric bicycle. A manufacturer’s class label is shown here, but it never bypasses the spec check below.

02 / Cited specifications

Every figure traces to a fetched source

The facts that decide the verdict

Motor — nominal (rated)

Not publishedThe fetched official handbook does not state a motor wattage. SUPER73's product page (super73.com), which lists 750 W nominal, was not machine-fetchable. 750 W nominal is widely reported and consistent with the Class-2 programming, but is not confirmed from a fetched primary source, so the engine relies on the verified Class-2 programming, top speed, throttle, and operable pedals rather than an asserted wattage.Unverified — no fetched source states this.

Motor — peak / maximum

Not publishedNot stated in the fetched handbook.Unverified — no fetched source states this.

Vehicle top speed

20 mph2026 U.S. factory Class-2 configuration (motor-powered assistance to 20 mph). The SUPER73 App can reprogram ride modes; only the factory Class-2 mode is in scope here.SUPER73-S2 Owner's Handbook (Assembly & Maintenance, EN 2025)

Pedal-assist cutoff

20 mphHandbook: the S2 comes programmed in Class-2 ride mode, which allows throttle operation and pedal-assist riding up to 20 mph.SUPER73-S2 Owner's Handbook (Assembly & Maintenance, EN 2025)

Throttle-only cutoff

20 mphHandbook: Class-2 ride mode allows throttle operation up to 20 mph.SUPER73-S2 Owner's Handbook (Assembly & Maintenance, EN 2025)

Throttle present

YesHandbook: once the display is illuminated, "the throttle or pedal assist" will be active (thumb throttle).SUPER73-S2 Owner's Handbook (Assembly & Maintenance, EN 2025)

Fully operable pedals

YesHandbook: the S2 ships with a set of pedals (marked L/R) installed on left/right cranks, and a pedal-assist sensor (levels 0–4) that activates when pedaling; the bike is pedalled for pedal assist.SUPER73-S2 Owner's Handbook (Assembly & Maintenance, EN 2025)

Nominal (rated) and peak power are kept separate — never merged into the statutory motor rating. Facts marked Unverified could not be confirmed from a fetched manufacturer source and are excluded from the per-state defeating-fact logic. Classification facts (Class-2 programming, 20 mph, thumb throttle, operable pedals + pedal assist 0–4, fixed seat, two wheels) taken from SUPER73's official S2 owner's handbook (EN 2025), retrieved from a dealer-mirrored copy of the manufacturer document. Motor wattage is not stated in the handbook and SUPER73's own product page was not machine-fetchable. This is a multi-configuration / app-updatable gray-zone model: this page covers ONLY the 2026 U.S. factory Class-2 mode. Re-verify monthly.

03 / Why it is — or isn’t — an e-bike

The definitional facts that decide it

Every state’s electric-bicycle definition turns on the same handful of facts: operable pedals, motor power, and how fast the motor keeps assisting. This machine’s cited figures — a throttle, motor assistance to 20 mph, and fully operable pedals — are run against each state’s electric-bicycle definition below. Where a state isn’t verified here yet, the row says so rather than guessing.

04 / State by state

The cited S2 verdict in all 50 states + DC

This addresses electric-bicycle classification only. It does not by itself decide whether a machine can be registered or operated as another vehicle type; where a primary agency source resolves that, it is noted in the row.
