Super73-ZX Review: Stylish Urban Electric Bike with Pedal Assist

Electric bikes are charged, and this fact is not missed by Irvine-based Super73. The five-year-old brand offers a line of pedal assist electric bikes that aim to make the riding experience as easy and intimidating as possible, combining some motorcycle influence with classic elements of the 70s beach lifestyle. and 80. And it’s a new take on the larger two-wheel world, one that naturally gravitates towards performance, as shown by the growing offerings available for commuters, roads and pedal-assisted mountain bikes. It’s at one end of the spectrum, as things like the new Super73-ZX all focus on one thing: fun.

Super73-ZX review: MSRP

To date, the brand has released three distinct lines of single-speed e-bikes that all follow its sleek, retro-cruiser theme. The main differences are in components and suspension, with the R series offering full suspension, the S series only offering front suspension, and the Z series semi-rigid.

Super73-ZX Review: Price

Well, someone at Super73 has exquisite taste because they managed to roll out the red carpet at the illustrious Peterson Automotive Museum, where I spun the new ZX amid one of the finest collections in cars and motorcycles to the world. The BMX-inspired ZX barebone features a lighter aluminum alloy frame, a removable 615 watt-hour battery and a pleasant upright riding position.

Super73-ZX Review: Specifications

As someone with a BMX background, the inherent simplicity of the ZX speaks to me personally; What you see is what you get. A long, well-padded bench seat measures 31 inches, and with no actual bulk on the ZX, smaller riders will never have a problem putting their feet up. Meanwhile, the placement of the pedals and the high handlebars encourage a moped-like riding position. The set is light, easy to handle, and the only real requirement is to know how to ride a bike.

What separates the ZX from traditional e-bikes I’ve ridden is that it offers electric pedal assist, as well as a thumb throttle to let the hub motor run at 750 watts (1350 watts of power). peak) accompany you without ever a drop of sweat.

New to the ZX is a Bluetooth-enabled LCD screen that lets you choose between Class 1 (pedal assist, top speed 20 mph), Class 2 (on-demand throttle, top speed 20 mph), Class 3 (pedal assist, 28 mph top speed) or Unlimited mode (28 mph top speed). This ensures compliance with e-bike regulations for your streets and trails. Additionally, there are four power modes – Eco, Tour, Sport and Super – which must be selected from the Super73 app, available on iOS and Android.

To be clear, the ZX is sold as a Class 2 electric bike, which means it’s legal for road use in California without motorcycle approval, registration, or insurance – your state may vary. However, the different modes give you more leeway with maximum power.

Regardless of the mode, the available power is carefree and inviting, gently accelerating the line before reaching the impressive 28 mph limit in unlimited mode. I usually pedaled a bit to help the ZX get started, and then shifted from the thumb throttle to the old-fashioned crank while hopping sidewalks and skidding as I liked. Everything about the ZX is laid-back and inviting, lacking the kind of low-speed or top-speed torque that might intimidate those with no e-bike or motorcycle experience.

Of course, range is a sensitive issue for all e-bikes, and it depends on how they are used. Super73 claims the ZX can go around 30 miles at 20 mph with the throttle alone, while still hitting an impressive 50 miles in Eco mode with pedal assist. Charging times are approximately seven hours with the standard 2A charger. That drops to just two hours with the optional 5A charger.

The large 20 x 4.5 inch LZRD Street tires not only provide sufficient grip and are your only means of suspension on the ZX hardtail. They do a great job of grip on asphalt and do their best to hide most of the rough elements in the road. Suspension is only missing when you’re ambitiously riding the 63-pound e-bike and not absorbing the landing properly. Then again, that’s a bit outside of his Causal Cruiser area of ​​expertise, but that didn’t stop me and the ZX. When it comes time to clean up all that gear, you’ll have cable-actuated brakes attaching to a 180mm rotor front and rear; they are functioning properly.

The price starts at $ 1995, which is not to be sneezed at, although this is not uncommon in the emerging market for e-bikes. In the spirit of customization, a plethora of options are available for the Super73-ZX, ranging from lighting, fenders, suspension and more.

At the end of my quick foray with the Super73-ZX, the possibilities seemed wide open. Neighborhood grocery store? Sure. Fast shuttle buddy? To verify. They’re great in groups, and it’s a wonder why every Airbnb or beachfront hotel isn’t stocked with a fleet of them. Performance doesn’t say everything. Sometimes it’s just about having fun.
