GOTRAX Mustang Review | Good Looks, Great Fun & Giddy Up

In case you missed our list of Pros and Cons above, the Mustang’s performance in our Range Test was particularly impressive, and the reason for its success is relatively simple.

We usually test e-bikes using both their highest and lowest (or lowest practical) PAS levels. With moped-style e-bikes like the Mustang, however, we test their range on throttle-only power, as described in the graphic above. Our test rider traveled 28.7 miles on a single charge—one of the longest results we’ve recorded from this style of e-bike.

While, at the time of writing, this is one of our smallest categories, a group of similar moped-style models traveled an average of 24 miles on throttle power under the same conditions.

On average, these e-bikes carried smaller batteries than the GOTRAX Mustang. In comparison to its 720-Wh battery, this group used power packs that averaged 608 Wh in capacity. As such, the Mustang had more energy to use, allowing it to stay on the path where we performed our testing for a longer time.

Interestingly, the Mustang’s energy consumption was similar to that of its peers. By dividing battery capacity by the distance each bike traveled, we can determine the watt-hours it used per mile (Wh/mi). The Mustang expended 25.1 Wh/mi, while other bikes averaged an even 25.0 Wh/mi.

Considering that most riders we interact with usually travel under 20 miles per round trip, the Mustang’s throttle range should accommodate users enjoying the bike for leisure, commuting, etc. Based on its status as one of the longest-range moped-style e-bikes we’ve tested, the Mustang is ideal for anyone seeking relief from range anxiety—this bike can go the distance!

Our only point of critique relating to this test is the bike’s bar-based battery charge indicator. While it matches the display’s power meter and motor temperature readout in appearance, we find that bar-based systems make it tough to estimate remaining range. As such, we feel that a percentage-based charge meter would be more user-friendly.

Otherwise, the Mustang performed well in this test. Additionally, it should charge in a manageable time frame; GOTRAX included a 3-amp fast charger that should recharge the 15 Ah battery in around 5 hours.

Continuing its trend of strong performance, the GOTRAX Mustang matched the Hill Test averages among similar models we’ve reviewed, and showed some potential for even better results.

We tested the bike at our standardized location, called the Devil’s Backbone, as explained above. Our test rider, Justin, rolled to a stop after throttling uphill in 1:53, while pedaling in PAS 5 reduced his climbing time to 1:48. He maintained an average speed of 16.0 mph in the throttle portion of the test and 16.8 mph with the addition of leg power.

Similar e-bikes we’ve tested, including many of the best moped-style e-bikes on the market, completed their tests in 1:53 and 1:50—nearly identical to the Mustang.

This is an impressive showing of the Mustang’s power, especially when considering that its motor is slightly less powerful than average. The 750W motor GOTRAX selected peaks at 1000W and can produce 90 Nm of torque, while our relatively small group of comparison e-bikes averaged 1190W of peak power and 92 Nm.

A key factor seems to be the Mustang’s lower-than-average weight. Compared to similar models we’ve tested that weighed 85 lbs on average, the Mustang’s 78-lb weight meant that its motor had less bulk to move up the hill. As such, it was able to do more with less—equal or slightly faster climbing with a small step down in power.

Ultimately, our testing showed that the bike is just as capable as other, sometimes more expensive, models. Its 750W motor is powerful enough to give riders the option to pedal or throttle, but not so powerful that it’s intimidating to ride.

After three Brake Tests done using the method explained above, the Mustang’s average stopping distance was a solid 20’6”. This final result is exactly a foot beyond the moped category average of 19’6”, but still an excellent score. Let me explain.

The first point to cover is that the GOTRAX Mustang is equipped with a capable, common hydraulic brake system: the Tektro HD-E3520 model. This two-piston brake system, which includes a motor cutoff function and 180mm rotors on both wheels, appears often on e-bikes that we review. It has proved to be safe, reliable, and effective.

Second, our comparison group includes e-bikes with stronger 4-piston brakes; these systems have larger brake pads and apply more distributed force on them when engaged. As such, these bikes had significantly shorter than average stopping distances that skewed our average results somewhat.

Third, a bike’s feel is often more important than its data. In my experience, the Mustang’s brakes felt powerful, and even somewhat aggressive, but not so much that they were hard to control. The calipers applied plenty of force with a moderate squeeze of the brake levers, easily modulating speed when riding down hills and stopping the bike quickly on flats.

Finally, moped-style e-bikes are often great performers. Many e-bikes in other categories—that we consider safe—often exceed the 22’ mark, making the Mustang’s result well within our expectations.

In short, the Mustang is well-equipped and safe, with a common, easily-maintained system that provides effective stopping power.

The Mustang’s overall ride quality, which is a measure of its comfort, user-friendliness, responsiveness, etc., was generally solid. I found much to appreciate about the bike, including its overall simplicity and ease of use, though there may be some important considerations for some riders to keep in mind.

GOTRAX offers the bike in a single frame size that is designed to fit riders from 5’4” to 6’2”, so my height of 5’11” places me near the top end of its recommended range. I found the bike generally comfortable when throttling, though it could be somewhat cramped when pedaling.

As I mentioned previously in this review, e-bikes of this style often feel somewhat inconvenient to pedal due to their low positioning and non-adjustable saddle. In my experience, scooting back on the saddle improves comfort, but the Mustang’s flared, relatively short seat limited my ability to do this.

As such, riders on the taller end of the spectrum may find themselves in my shoes, but those on the lower end—or those who plan to throttle most of the time—should be fine.

I enjoyed the overall smoothness of the ride, made possible by a combination of the Mustang’s suspension, saddle, and tires. Its dual-crown fork, which matches the bike’s edgy aesthetic, offers a respectable 80mm of travel, while its thickly padded seat and 20×4” fat tires add an additional layer of cushioning.

Most moped-style e-bikes I’ve tested previously were larger and heavier than the Mustang, so I appreciated this bike’s uncommonly nimble, more playful feel. It’s not a lightweight e-bike by any means, but its size and weight create a great balance between agility, stability, and plantedness.

I primarily rode the bike on paved trails, but I also ventured off-road for some brief testing. The bike performed well on hard-packed dirt and loose gravel, making it appropriate for limited adventuring off the beaten path.

As I referenced previously, I found many qualities to appreciate about the Mustang’s torque-sensing pedal assist system and 7-speed drivetrain, including its controllable power and easy pedaling. That said, I believe a properly-programmed cadence-sensing PAS paired with a single-speed drivetrain could potentially deliver the same benefits while reducing cost and weight.

A setup such as this would also complement the Mustang’s already low learning curve and easy to grasp user interface. The display is probably the most complex aspect of the bike; its large color screen packs in a lot of data with bold, unique presentation and good organization.

I greatly enjoyed the bike’s overall simplicity. Many e-bikes on the market are loaded with an abundance of features (Bluetooth apps, complicated settings menus, etc.) that increase their functionality, but their higher learning curve may be intimidating to some riders. The Mustang takes the opposite approach by sticking to the basics and keeping its operation simple and effective.

This approach extends to its components and accessories; the Mustang is outfitted with just enough to be useful, not overwhelming or overcomplicated. It includes integrated lights and fenders, and a small, frame-mounted cargo box. GOTRAX offers a handful of additional accessories for those who wish to outfit their bike further

An e-bike’s price often sets the bar for our expectations, and after testing the GOTRAX Mustang, I can confidently say that the bike offers strong value for its cost. It looks cool, it’s fun to ride, and it’s powerful enough to satisfy those riders who will likely find it appealing, while still feeling easy to manage, understand, and operate.

The bike demonstrated impressive performance capabilities in our testing, with five incrementally-spaced power levels and excellent throttle-only range. It also proved every bit as capable as its peers in its hill climbing power, and showcased safe, strong stopping ability.

Clearly, this is an e-bike for riders who want a moped-style ride with personality, power, and range without spending a boatload of cash. It’s backed by a relatively standard two-year warranty, and while it wasn’t UL certified at the time of our testing, our contact stated that consumers should expect to see this status changed soon after.

Our largest points of critique concerned the throttle’s speed control and the display’s battery charge readout—both relatively small potatoes in the grand scheme of things. Considering the bike’s geometry, we encourage GOTRAX to tie throttle speed to the same five limits as the pedal assist system. And, while the display looks cool, we tend to prefer percentage-based charge meters for easier estimation of remaining range.

Otherwise, the Mustang was a strong addition to the ever-growing list of models we’ve tested. I had a lot of fun riding, testing, and reviewing it! Based on my experience, I’d recommend it the most to riders of relatively average height who want a moped-style e-bike to commute and cruise on.
