Super73 has spent the better part of a decade building one of the most recognizable bikes on the street. Started in 2016 out of Irvine on a Kickstarter that raised nearly half a million dollars, the brand turned a fat-tired, bench-seat minibike into a full-blown lifestyle movement. Now, approaching its ten-year mark, the company is making its biggest product move yet with the A-Series, a ground-up redesign that takes direct aim at one of the brand’s longest-standing criticisms: fit.

Back to the Drawing Board

Super73 rebuilt its A-Series from the ground up. For a brand that’s spent years iterating on a proven formula, scrapping the platform’s essence entirely is a real commitment. What came out the other side is a six-model lineup structured around three seat height platforms: 27″, 30″, and 33″. The MZFT at 27″ carries over from its recent debut as the compact model. The M1D at 30″ is the new sweet spot, and the B1G at 33″ is the first Super73 that earnestly works for taller riders who previously had to contort themselves to fit the brand’s characteristically low geometry. That sizing issue has been a major criticism of users for years, and addressing it across three distinct platforms shows how well they listened to the feedback.

The Modular Battery

At risk of burying the lede, we need to discuss one of the more technically interesting additions of the A-Series: the secondary, modular battery system. Built on a 52V platform, each battery pack offers 520 Wh and weighs in at about 8 lbs. Stack two of them and you’re just over 1 kWh of capacity, which is notably high for any pedal-assisted vehicle. You can essentially ride on one battery for shorter commutes and then add range incrementally if need be. Other e-bikes force you to opt for heavier, permanently larger batteries, even if you only occasionally push that range. Now it’s in a much smaller package, and gives you flexibility as well. Combined with newly integrated onboard storage, the A-Series is clearly trying to close the gap without sacrificing the signature Super73 aesthetic.

Standard vs. SE

Each platform offers a base and a Special Edition version. The SE trims earn their price with larger batteries, adjustable front suspension, and a new digital display that lets you activate pedal-assist and the headlight, and gives you information on current range and battery life.

Super73 A-Series E-Bike Line

Super73 just dropped its most ambitious lineup yet with the A-Series, a ground-up redesign that finally tackles the brand’s long-running fit problem by offering three distinct seat height platforms, a modular battery system, and enough commuter-friendly upgrades to make these bikes as practical as they are cool to look at.
