Chassis components and frame design

The Surron X is using a pressure forged aluminum chassis with an aluminum alloy swing arm for a lightweight and durable construction. Additionally, the front fork is an inverted with about 8″ of travel. The triple trees are common with many mountain bikes and use a similar axle design.

The owner’s manual explains few of the features well.

Few things to note: The side stand has a kill switch. This prevents the bike from giving power when the side stand is down. A common feature in street bikes and still easy to forget. You also need to wait few seconds when powering on and twisting the throttle to let the computers to run its initial calibration.

Another thing worth mentioning is that the model is equipped with a headlight, a rear light, and a horn, so it can be made street legal with ease. Check other street legal dirt bikes here.

Surron X Review

When you order the bike online, it is delivered in a box requiring final assembly. Fear not, it is not hard at all and requires no special skills.

Unboxing and Assembly

The box includes all tools needed for the assembly with instructions. Additionally, you can easily follow this great unboxing and assembly video for more details.

Putting the bike together is a fairly simple process. In case you’re wondering, you really do not need any special skills or tools to finalize the assembly. The package comes with the electric dirt bike mostly assembled and should take less than 30 minutes to finish.

The rear wheel is already installed. Furthermore, the only parts you need to install is the front end with the front wheel, handlebars, forward controls, headlight, and the display. Finally, you need to install the foot pegs and recharge the battery and you are good to go!

First Impressions

The form factor and chassis reminds me more of a mountain bike than a dirt bike. Surprisingly, the front end is identical to a mountain bike and the handlebar feels like in a high-end mountain bike. It’s a good feeling.

The chassis is narrow and lightweight aluminum and it makes the eBike feel overall very light. The Surron X weights around 104lbs without the battery and the stock battery adds another 20lbs, totaling the overall weight to 124lbs.

Forward controls include rear brake level on the left and front brake lever on the right. As a result, both engage a 4-piston disc brake. Other controls include a large speedometer that includes odometer, trip meter, and total distance. You can also toggle the menu to view the current battery charge.

You also have a switch on the left hand side, which works as a power mode selector between ECO and SPORT mode, and a separate horn.

The dirt bike comes with a key that powers it on and also is used to lock the replaceable battery in place.

Test Ride

Riding the Surron X is a great experience. I have tested several electric cars, mountain bikes, scooters, and one wheels but this one is by far the most fun I have had with any electric powered vehicle.

Powering on the bike is simple. Simply, turn the key on, wait a few seconds for the controller to cycle, and power on. Next, switch the display lights on and you are ready to go.

After getting used to the throttle response and new lever configuration, the first feeling is similar to a trials bike or a mix between a mountain bike and a trials bike. Furthermore, it feels very light, narrow, and very easy to balance with.

Overall this dirt bike is easy to control and the motor feels strong enough to easily pull a slow wheelie. During the test, the suspension felt very soft and needed to be tweaked to my weight and riding style. I used the front fork clickers to stiffen both the compression and the rebound until the suspension had enough dampening.

Trail Test

Next, we took these eBikes to a local trail and put them to the test.

The riding reminds me more of mountain bikes than dirt bikes. This is mainly because the handlebars, forward controls, and no sound is very similar to a mountain bike. The overall lightweight and narrow chassis makes the bike very nimble and fast.

Cornering, especially maintaining speed throughout the corner, is easy and very predictable, at least in good dry conditions. The stock suspension does feel a little slow or maybe too soft and would benefit from a better suspension setup for more advanced riders.


The throttle response needs improving. There is a noticeable delay or slack on the throttle. When you get on the gas, I am used to an immediate raw power that comes on immediately when using the clutch and flywheel in gas powered dirt bikes.

This is completely different with the stock Surron X. I had to teach myself to get on the gas about 1 seconds sooner. The power also comes on slower and is more mellow. It was specifically noticeable when braking hard and getting on the gas. Surprisingly, I almost went over the handlebars the first time I was cornering while waiting for that power to come on and leaning too much forward. This feeling never fully went away and would be the first thing I would fix on the eBike.

Overcoming obstacles, roots, and rocks is easy with this eBike. Basically, after learning how to use the power in combination with the brakes, things got easier. Additionally, using the rear brake with your left hand enables fine tuning the power delivery and helps to increase traction.

Last year, I had a chance to ride behind a skilled rider with a tuned SurRon on a very technical single track. Surprisingly, he was very fast around the slow speed sections and cornering to a point that I really struggled keeping up with him on my gas dirt bike. The only places where I was catching up were high speed straight sections over a grass pastures when his bike was limited with its maximum speed.

Surron X Top Speed

The Surron X has a top speed of 47mph, which is very well adequate for most trail riding. Bypassing the max power and top speed is easy by cutting a wire in the controller, however, most beginner riders really would not even need to do that. If you ride single track, the top speed should not really matter. Speeds over 50mph rarely happen in most trail riding but more power is always welcome.


I also tested the same eBike with few important upgrades. First of all, I like how the stock model can be upgraded with many aftermarket parts. And that they have opted to use parts from mountain bikes, such as the triple trees, handlebars, and other front fork parts. This makes it easy to configure and upgrade to your liking.

The tuned version had upgraded battery, controller, suspension, and tires.

First of all, the throttle response is where it needs to be. Using the new controller, the throttle response was crisp and had basically no delay. This made riding much more predictable and easier.

The upgraded suspension together with a new trials style tire choice definitely made the Surron X much more fitted to my riding style. The stock front suspension felt too slow to response to some repeated heavy bumps and felt frequently like bottoming out. Basically, this feeling was completely gone with the upgraded suspension and it made the eBike float over any bumps with ease.

All in all, I would like to take the tuned version to some very technical and hard terrain with big climbs to fully test the capability of these electric dirt bikes and how well it would perform without clutch and gears.

Overall the difference is noticeable compared to the stock version and if you are an advanced rider, be prepared to upgrade at least the suspension to enjoy this eBike to the fullest.
