SUPER73 S2 / R / ZX: Everything You Need to Know
Three families, not one bike. The US S2 card is $2,995, 960Wh, and 73 lb, with an off-road mode past Class 2. A US Z Adventure card is 600W and 480Wh. An EU ZX presale is 250W and 615Wh.

The short answer
These are three families, not one $2,000–$4,000 moped. The live US S2 card is $2,995 with a 960 Wh pack, and 750 watts nominal in the class modes. Z Adventure Core is $2,895 and 480 watt-hours. The EU ZX presale is €2,799 and 615 watt-hours. A July grid’s 720 Wh S2 is not this live card.
SUPER73 S2, R, and ZX are three families, not one moped at $2,000–$4,000. The US S2 page prints $2,995, a 960 watt-hour pack, 73 lb, and 750 watts nominal in the Class 1, 2, and 3 modes, with a 1,200 watt peak in those modes. Off-road mode on that page is 1,200 watts nominal and a 2,000 watt peak, with a note that a later update would raise the peak to 2,300. Class 2 is 20 mph. Class 3 is 28 mph with the throttle off. Off-road is “28 mph +”. A US Z Adventure Core card, the bike SUPER73 now points at the old ZX idea, is $2,895, 20 mph, 600 watts nominal, and 480 watt-hours. An EU ZX presale is €2,799, a 250-watt EPAC motor, and 615 watt-hours. The RX is a different argument, and the US catalog still does not title an RX. The row on this desk’s list links here.
What each live card actually prints
Three SUPER73 pages opened for this note. A July 2026 shopper table said an S2 SE was 720Wh and 71 lb at $2,995. The live US S2 page says 960Wh and 73 lb at that same dollar. EU R Adventure Core and SE were €4,799 and €4,999. This crawl did not open a US R dollar.
| US S2 | US Z Adventure Core | EU ZX presale | |
|---|---|---|---|
| Price | $2,995 | $2,895 | €2,799 |
| Motor | 750W nominal / 1,200W peak in class modes. Off-road 1,200 / 2,000, later note 2,300 peak. | 600W nominal | 250W EPAC |
| Speed | Class 2: 20 mph. Class 3: 28, throttle off. Off-road: 28+. | 20 mph | Not a US class menu. Range is given in km. |
| Pack | 960Wh | 480Wh, called 48V 10Ah | 615Wh, called 48V 12.8Ah |
| Mass | 73 lb | 73 lb | 28 kg |
| Pedals | Yes. Throttle plus pedal assist, and class modes. | Yes. 8-speed. | Yes. EU note: no throttle, 8-speed. US photos are called out as the wrong spec. |
Forty-eight times 10 is 480, so the Z Adventure label is consistent with itself. Forty-eight times 12.8 is 614.4, so the EU 615Wh line is that product rounded. The S2 page prints 960 watt-hours and does not print the amp-hours beside it. A 720 watt-hour S2 in a July roundup is not this live card. Do not average 480, 615, and 960 into one battery. Off-road mode at 2,000 watts peak is still a SUPER73 sentence. It is not what Class 2 means. Class 2 on the S2 page is the 20 mph default. The EU ZX at 250 watts is a different legal object from the US S2’s off-road map. The R family is the third name in the list slash. European collection prices are not a US R MSRP, and this note will not invent one.
The Instagram shape is a family. The legal object is whichever mode the bike ships in, and these three cards do not ship as one mode.
Who it is for
Buy an S2 if you want that $2,995 US card and you will leave off-road mode off the street. Buy the Z Adventure card only if 480 watt-hours and 20 mph is the bike you meant by ZX. Buy the EU ZX only if you want the 250-watt presale, not the American photo. None of this is the class chart in a single cell. The chart is the page that says which mode is a bicycle and which mode is not.
Questions people ask
What ships as the street mode?+
Class 2, 20 mph, throttle on, is the default the US S2 page describes. Class 3 is 28 mph with the throttle deactivated. The off-road map is a third choice. Do not describe the third choice as how the bike is legal.
Which ZX is for sale?+
In the US, read the Z Adventure Core card: 20 mph, 48 volts, 10 amp-hours, 73 lb. In Europe, read the presale: 28 kg, cadence sensor, no throttle, eight speeds. Same nickname, two builds.
Did you find a US R price?+
No. The EU collection showed R Adventure Core at €4,799 and the SE at €4,999. Those euros are not a dollar MSRP. This note will not convert them.
Why mention 960 and 720 together?+
A July 2026 shopper grid put 720 Wh and 71 lb on an S2 SE at the same $2,995. The live page puts a larger pack and 73 lb on that dollar. Hold the page you opened.

SUPER73 RX: Everything You Need to Know
SUPER73’s US catalog does not list an RX. Dealers still print a Mojave at $3,695 with a 2,000-watt peak. A Blackout card is 750 watts nominal, 90 lb, and 20 mph.

What Is a Class 1, 2, and 3 E-Bike?
Class 1 is pedal-assist to 20. Class 2 adds a throttle to 20. Class 3 is pedal-assist to 28. A Tuttio is none of these. The sticker is not the trail.

Florida This Week: Jacksonville’s 15 MPH Cap, and an Oviedo Stop
The 19-0 vote is a Duval sidewalk rule, not a new state law. In Oviedo, police say 4,500 watts and no pedals. The father says 20 mph. Do not average them.
