Euphree Solar Sparrow Review | This Bird Can Fly

Euphree advertises up to 50 miles of range on the Solar Sparrow, and in our testing, that claim held true. Riding on local bike paths with the bike set to Class 2 compliance and its default torque sensor mode, we recorded solid results.

In Eco mode, the Solar Sparrow lasted 56.5 miles before the battery tapped out. On the opposite end, Turbo mode delivered 22.2 miles. For context, our current averages for similar lighter-weight cruisers are 56.7 miles in low assist and 27.8 miles in high assist. That puts the Sparrow right in line with its peers, with slightly less range at full power but stronger climbing performance to balance things out.

A helpful feature here is the ability to reprogram assist levels. Riders who want to stretch mileage further can tone down the output aggressiveness in each PAS mode, effectively trading a bit of punch for increased endurance.

Where the Sparrow could improve is its battery gauge. While it uses a percentage display (our preferred format), the readout drops in large increments of 7–9%, which makes it harder to track usage accurately. Familiarizing yourself with your daily route is advised.

Charging is handled by a standard 2-amp charger, bringing the 10.5Ah battery to full in just over five hours.

Lightweight cruisers often equip 500W motors, but the Solar Sparrow goes bigger than most with a 900W peak output and 75Nm of torque—and it shows on the hills.

On our Devil’s Backbone test climb (a half-mile, 8% grade), the Sparrow proved one of the quickest cruisers we’ve tested. Using throttle only, it reached the top in 2:01 at an average of 15 mph. When pedaling in Turbo (torque mode), it clocked in at 2:06.

Confused by a slower pedal time than throttle one? That’s not unusual as torque sensors sometimes register a touch slower since they modulate power to match rider effort, whereas throttle-only is giving the bike permission to go full bore, and often a good stand-in for how a cadence sensor would perform (we used the torque sensor on this test).

For context, the current average among cruisers at our new test hill is 2:22 on throttle and 2:20 when pedaling. The Sparrow handily outpaces those benchmarks, making it one of the peppier options in this category.

Speaking personally as a larger rider (235 lbs), I tend to brace for “lightweight” e-bikes to feel underpowered. The Sparrow didn’t. It delivered steady, confident climbing power that felt every bit like a full-strength cruiser. Having a bike with that kind of power is great for single-speed systems, too. It helps you feel less nervous with a lack of gearing options.

For a bike that emphasizes comfort, easy handling, and a lower weight, it’s impressive to see that you don’t have to trade away power. You really can have both.

The Solar Sparrow uses the Tektro E350 hydraulic system with 2-piston calipers and 180mm rotors. It’s a common and proven setup found on plenty of e-bikes. It delivers reliable stopping power and is easy to service at most shops.

In our brake test, the Sparrow averaged 22’8” from 20 mph. That’s just slightly longer than both the cruiser average (22’5”) and the all-bike average (21’8”) in our database.

The reasons why it went longer are unclear. There’s nothing unusual about the geo or tires, and weight is on the low side, too.

While a touch above average, the results are still well within a safe and dependable range. The brakes felt consistent and predictable—no unpleasant surprises, which is ultimately what you want most out of a braking system.

Euphree has a knack for nailing the finer details, and the Solar Sparrow shows that off while also getting the basics right. I have a couple of wishlist items, but when it comes to feel and overall ride quality, this is a well-executed bike.

The Sparrow weighs a manageable 60 lbs and comes in a single frame size, but it’s fairly adaptable. With a 16” standover height and a fit range of 4’11″–5’10”, it should suit most riders comfortably. At 6’1”, I still felt fine—leg extension was adequate and the adjustable stem kept handlebar height in a good place. The reach felt slightly cramped for me, but not enough to be a dealbreaker. Within the quoted size range, fit shouldn’t be an issue.

The Kenda Kwik Six 26” x 2.4” tires add to the approachable feel. Their semi-slick street tread rolled efficiently and gave dependable traction, with no flats during our testing. The reflective sidewall strip is a nice touch for visibility.

The monoshock fork is the “takes the edge off” type; the suspension won’t soak up everything, but it smooths out road chatter without the weight and complexity of a full suspension fork. The SR Suntour NCX suspension seatpost, on the other hand, was excellent. I find this rocker-style post more effective than cheaper spring posts, and with adjustable preload, it can be tuned to match rider weight.

Contact points are also well thought out: a plush saddle and ergonomic, soft grips made longer rides comfortable. Handling felt balanced—responsive without being twitchy, steady without being sluggish. It moves with purpose and confidence.

From a commuting standpoint, the Sparrow delivers. It includes a headlight, taillights, full fenders, and a 30-lb MIK-compatible rear rack. That rack earns bonus points since it makes swapping accessories quick and easy; the basket with a liner we tested snapped on and off in seconds.

The display is simple to read but loaded with customization options—more than you typically see. Riders can choose torque or cadence sensors, set throttle top speed, fine-tune PAS output levels, and adjust acceleration behavior. If the battery gauge were more precise, I’d call it excellent.

The Gates Carbon Belt Drive is another highlight: clean, quiet, and virtually maintenance-free. With a single-speed setup, riders using the torque sensor will need to spin a little faster at top speeds, but the gear ratio feels well-balanced—easy enough to start from a stop yet still comfortable up to 20 mph. Class 3 riders, however, might find better luck with Cadence mode.

Aesthetically, the Sparrow looks sharp. Multiple color options (our blue was stunning), braided cable housing, and even a built-in phone mount on the stem to cleanly carry your phone vs a bulky phone mount all add polish to the design.

As for value, I think you’re getting your money’s worth and then some. A slightly larger battery wouldn’t hurt (504Wh is on the modest side for a bike near the $2k mark), but the range still holds up well, and the extra punch from the motor helps balance it out. With its thoughtful details, comfort features, and adaptable performance, the Solar Sparrow feels like a win in the value department.

There’s no shortage of cruiser-style e-bikes on the market, but the Euphree Solar Sparrow stands out by matching—or exceeding—similar rides on performance, while adding thoughtful touches in style and comfort.

It delivers solid range and braking, with hill-climbing ability that outpaces most cruisers. Comfort features like two forms of suspension and an adjustable stem make it adaptable for a wide range of riders, and the motor’s customizable output gives you the freedom to tailor how the bike responds.

The styling is another highlight. With bold color options, a clean frame design, and the premium look and operation of a Gates belt drive, the Sparrow feels refined. At the same time, it’s practical, with standard lights, fenders, and a MIK rack system ready for daily use.

Riders seeking a capable, well-rounded cruiser will find a lot to like here. It’s not the cheapest option, but in terms of value for the price, the Solar Sparrow is one of the stronger total packages in its class.

Happy Riding! Make sure to let us know if you have any questions or if you think we left anything out in this review of the Euphree Solar Sparrow down in our comments section.
