About Super73
Super73 was founded in 2016 in Irvine, California, and launched through a Kickstarter campaign with a $25,000 fundraising goal. The design was deliberately provocative: instead of a sleek, forward-looking e-bike, the founders built something that looked like it came out of a 1970s garage, with a low-slung chromoly steel frame, fat tires, a thick padded seat, and proportions borrowed from mini-bikes and mopeds. Backers responded by funding the campaign to over $441,000, more than 17 times the original goal.
The moto-inspired aesthetic was not purely visual. Super73 bikes occupy a size and silhouette between a bicycle and a motorcycle, a category that barely existed before the brand helped create it. That distinctiveness made Super73 a natural subject for social media, and the company grew largely through organic content and video sharing rather than traditional advertising. A series of viral videos in the brand’s early years drove awareness faster than most e-bike companies could achieve through conventional marketing.
All Super73 bikes are Class 2 e-bikes with both pedal assist and a throttle capable of reaching 20 mph. The company sells direct to consumers online and through select retail partners. The lineup expanded from a single original design to three distinct lines covering entry urban riding, premium commuting, and full-suspension off-road capability. Super73 has also released limited-edition collaborations with brands and artists, reinforcing the cultural identity that has set it apart from more utilitarian e-bike competitors.
Most popular Super73 models
The Z line is Super73’s entry tier, built around lightweight alloy frames with mechanical disc brakes on the Z and hydraulic brakes on the upgraded ZX. Both models are compact and lower to the ground than the S line, making them popular with urban commuters who want the Super73 aesthetic at a lower price. The Z is the more affordable option, and the ZX steps up with a slightly higher spec and better braking feel.
The S line is the core of the range. The S1 is the original platform: a single-speed drivetrain, fat tires, and the chromoly steel frame that defined the brand’s silhouette. The S2 builds on the same chassis with a more powerful motor, a wider gear range, and hydraulic disc brakes. Both carry the moto-inspired proportions that made Super73 recognizable, and the S2 is where most riders land when stepping up from the Z.
The R line is the performance tier. The R is Super73’s first full-suspension model, adding front and rear suspension for a noticeably more capable ride over rough terrain and light trails. The RX is the upgraded version, with a higher-output motor and adjustable suspension for more demanding riding. Both R models handle surfaces that would be punishing on the rigid S or Z frames. All three lines are throttle-equipped Class 2 e-bikes, and e-bike insurance from Velosurance covers any Super73 model against theft, crash damage, and loss in transit.
The new A-Series flagship launched March 2026 — a 30-inch seat height moto-styled commuter with redesigned frame, modular battery system, and updated tech. SE trim adds a larger battery, adjustable front suspension, and a new digital display.
The A-Series taller-rider platform — 33-inch seat height for riders over 6 feet, same modular battery and tech as M1D. SE trim adds a bigger battery, adjustable suspension, and a digital display.
The A-Series entry — 27-inch seat height for shorter riders, the most accessible Super73 in the new lineup. SE trim adds larger battery and adjustable front suspension.
The original Super73 — simple frame, front suspension, comfy bench seat, no shifters. Raw, powerful e-bike that defined the moto-style category. Legacy production continues alongside the A-Series.
S1’s big brother, it is driven by a brushless motor with a 2,000 watt peak output and a 960 watt-hour battery. S2 features an improved, larger seat, integrated headlight, twist throttle and 4 piston disc brakes.
Sometimes, simpler is better, and the Super73 Z is a perfect testament. It comes with a 500 watt nominal, 1,000 peak power hub motor, an integrated 417 watt-hour battery, a rigid fork, and mechanical disc brakes.
This BMX-inspired bike comes with a lightweight aluminum frame, a removable 615 watt-hour battery and a 750 watt nominal, 1350 watt peak power motor. The bike has an upright seating position, and is configurable via bluetooth using a mobile app.
Riding on 20 inch fat all-terrain tires, this go-anywhere e-bike oozes quality and design. It can operate in Class 1, 2, and 3 modes, so it can be ridden on bike trails and go offroad, in Unlimited mode which provides 1,200 watts of normal and 2,000 peak power, enough to propel you up the steepest of hills.
Instantly recognizable as a Super73, RX is equipped with a 960 watt-hour battery that gives it 38 miles of range in the most motor-assisted of the four power modes. If you wanted to hyper mile this bike, you’d get 75 miles of range in the full pedal assist mode.
