11 reasons not to buy

Pedal assist takes one revolution to kick in when starting from a stop, and over two revolutions to reengage after coasting.
An expert says the motor struggles on steep hills, requiring a lot of input from the rider.
The narrow 635mm handlebars reduce rider control, in one expert’s opinion.
A tester says the frame geometry creates a higher center of gravity, which decreases stability.
Reviewers complain the color display is difficult to see in the sunlight.
The 120mm suspension fork is too stiff and does little to improve ride quality, according to several testers.
The display is integrated with the stem, so the stem can’t be swapped to improve fit.
An expert receives the bike with heavy scratches due to poor packaging.
The minimum seat height of 35.4” is too tall for riders at the low end of the 5'2" to 6'5" height range.
The Spark X is heavy at 84lb.
Eskute owners say customer support is difficult to contact and not very helpful.

Bottom line

The Eskute Spark X is a 750W fat-tire e-bike with a large 960Wh battery. Reviewers praise the range, speed, brakes, and tech features such as cruise control and companion app, though phone compatibility is limited. The ineffective suspension fork and instability at high speeds draw criticism. Additionally, all testers complain of delayed pedal assist activation when setting off, changing assist level, or switching from throttle to PAS. Contrary to Eskute’s marketing, this is not an actual mountain bike. Overall, the Spark X fails to stand out in a competitive fat-tire e-bike segment. Alternatives include Ride1UP’s Rift and Aventon’s Aventure 2.

Eskute Spark X Electric Fat Tire E-Bike

Level 1 expert

It’s the suspension that got me, it’s a little tough, it doesn’t give as much as I would’ve liked… Overall, I thought Eskute did a pretty good job of making the X stand out with the built-in LCD screen and app.

Cheapest Electric Bike on Amazon for Long Range – Eskute Spark X All-Terrain E-Bike Review

I really like this bike. So, I like that this is of course a big beefy bike that can handle off-road very well, [and] handles the curves very well. The suspension could be a little better.

2023 Eskute Spark X Review

When you start pedaling there’s a bit of a delay between throttle and pedal assist. I’ve got the throttle on and if I pedal then it cuts off a little bit and then it comes back with the pedal assistance.

Eskute Spark X Electric Bike Review / E-Bike Range Test in North Jersey

Overall, the build quality was superb, it rode amazing. The brakes [are] better than any e-bike I’ve ever ridden. If you’re in the market for a fat tire bike, this is definitely a contender.
