Q: Didn’t you used to be called Cyleagle? Why did you decide to rebrand to Propel EV?

Yes. As a company heavily focused on research, development and engineering, branding was initially something we didn’t prioritize to the same degree as all other aspects of our business. The original logo, for example, was designed by our CEO! After taking feedback from our riders and working with consultants and designers we realized the Cycleagle name and design language actually weren’t reflective of the kind of company we are. The style didn’t capture our style. Propel EV isn’t just a name to us; it’s an ethos. We’re confident we will propel personal electric vehicle technology forward. Our riders trust our products to propel them across any terrain. Never content. Never concerned about what used to be the norm. We will always propel forward.

Q: Are you marking down older Cycleagle stock to make way for the new?

Yes. We are marking down all remaining Cycleagle X4S stock almost exclusively due to visual aesthetic design change. Our 2021 X4S will also have nearly 50% more watt hours in battery capacity stock than our original 2020 Cycleagle X4S did.

Q: If I miss out on the 2020 markdown of the Cycleagle stock can you make more at the same price?

No. Once our 2020 models are sold out that’s it! If you wish to own a part of Propel EV history with a Cycleagle board from our Indiegogo era you will need to act swiftly.

Q: How are you able to lower pricing on the new 2021 and the 2020 edition?

Primarily through economies of scale. The research and development that went into building the X4S and the company was initially expensive but as sales have grown we have been able to leverage that growth through economies of scale and pass those savings onto you.

Q: What’s the difference between the X4S and X2S?

The X4S has 4-wheel drive with four 1000W brushless motors. The X2S has 2-wheel drive with two 1000W brushless motors. The top speeds of each board can both reach 45kph/27mph, but the 4-wheel drive version provides better acceleration and more torque for superior off road riding and hill climbing. The 2-wheel drive version is capable of  a 30% hill grade climb, while the 4-wheel version can achieve a 35% at maximum output. We highly recommend 4WD; however, the purchase is totally based on your preference and demands.

Competitive Advantages

Q: What are your core mechanical advantages?

Propel EV engineers have automotive backgrounds and we’ve brought that level of engineering sophistication to our product line. The X4S has a high ground clearance of 155mm/6.1”, surpassing that of its closest competitor by 2.6 inches, and ensuring a vastly superior pass-through. What good is an AT board that regularly bottoms out on rocks, tree roots, or even ruts in the earth? An X4S propels over just about anything that gets in its way! Its patented independent suspension shock absorption system allows for maximal tilting, as the dampening is exerted separately over each wheel individually. This also gives our boards unparalleled control and safety over any terrain you encounter. With an X4S any terrain is fresh pavement. Our adjustable springs allow for maximum flexibility and our customizable configurations allow for agile steering. The combination of these features gives the X4S an incredible turning radius of 130cm-230cm, making 3 point turns a thing only for other boards.

Q: What are your core electronics advantages?

Where many in esk8 make their batteries entirely inaccessible for easy change our philosophy at Propel EV is to make batteries removable and easily upgradeable in the future. We want you to have options to suit your own unique lifestyle. Have you ever wanted to leave your AT board in the trunk of your car for easier access later but worried that the temperature of your environment might impact your battery? With Propel EV’s removable batteries you can charge your batteries in your home and leave everything else in a location that’s convenient for you later. Forget the days of pulling ATs with muddy tires through your home to get to your chargers. With Propel EV you charge on the board or separately wherever it’s best for you. With the ease of a backpack or a rear storage rack mounted to an X4S range simply can’t be viewed the same way. You’re limited only by what you or your board storage solution is willing to carry. Battery accessibility goes beyond range options though. We’ve all seen the posts online from other riders who own other products from other companies that experienced battery issues. Those riders are stuck with an inoperable board, waiting for a replacement battery, and required to remove enclosures and more to resolve. A Propel EV rider with two or more packs doesn’t only have extended range; they have added assurance of uptime.

Q: Why is Propel EV not focused as much on max speed as some others in the industry?

Propel EV loves speed but we also value torque, comfort of ride, high pass through ground clearance, maneuverability, stability and safety and we believe we’ve created one of the world’s best esk8 and personal vehicles because we’ve found an incredible balance of each.

Q Is your esk8 strong and built to last?

Many of Propel EV’s engineers have backgrounds in automotive R&D where the expectation is that vehicles must be built to last. We have done force analysis of each part, and have established our own quality management standards in accordance with the standards of the automotive industry. We strictly control the precision of our products to avoid unnecessary wear and tear of the parts. Each of our non-consumable parts has passed the 20,000-kilometer endurance test. For consumable easy-wear parts, such as tires and belts, we utilize quality components to extend wear life. For some moving parts, such as bearings, we use SKF NSK high-quality bearings.

Battery/Remote control

Q Some esk8  companies don’t take battery safety seriously. Is it true that Propel EV batteries are UL safety certified?

All models of Propel EV products, including our battery packs, have passed the UN38.3 certification, the compulsory standard required by the US Department of Transportation. UN38.3 is found in many countries’ shipments of dangerous goods regulations and is relevant for the transportation safety of all lithium metal and lithium-ion cells and batteries. While the UL2272 standard is incorporated in some countries, UN38.3 is the most universal standard for most balance vehicles in most countries. We take battery safety very seriously at Propel EV.

Q: I realize that Propel EV believes in flexible replaceable battery concepts for riders but what’s the capacity of your quick swap batteries?

In 2020 our standard battery offering was a 14Ah/522Wh pack. In 2021, we have upgraded our stock battery to a Samsung battery with 21Ah/756Wh. A nearly 50% increase in watt hours.

Q: Can I buy more than the one stock battery?

Yes! Of course! Our entire reason for quick swap batteries of this type is to give you options and flexibility. Regardless of whether you own a 2020 X4S or a 2021 X4S you have access to our 756 Wh quick swap packs. We offer an additional battery pack as an optional accessory, which features a longer battery life. The battery life of 756Wh in 4WD is able to sustain up to 25km/15.5miles and on the 2WD version it’s 28km/17.4miles. This was tested on a rider of 165lbs. Carry as many packs as you wish to extend range.

Q: Will the battery fall during off-roading?

Propel EV planned for and tested for precisely this concern. The unique fixing and locking design can ensure that the battery is still very firmly fixed in the battery compartment regardless of terrain.

Q: Can I control the speed remotely?

You can control the board remotely with the function button on the remote controller and switch to different board speed.

There are four speed modes LOW/MIDIUM/HIGH/PRO that you are able to choose from, with speeds of 5,14,30,45 km/h in respective.

Q: Can the board be controlled in reverse?

Yes, the esk8 has a reverse control option. You can press the power button twice quickly to switch forward and backward.

Q: What should I do if the remote control is out of power (how long will the battery last)?

You can charge the remote control with a USB cable at 5V/1A for an hour to its full battery level.

Q: What if I’m a developer rider? Is there anything on the board to help me develop confidence?

Yes. There are four-speed modes LOW/MIDIUM/HIGH/PRO that you are able to choose from, with a speed of 5,14,30,45 km/h. Feel free to switch to low speed for a safer ride if you are a beginner. As you gain in confidence you can increase the speed modes, acceleration curves, and braking modes. Always wear a helmet and protective equipment to ensure safety.

Pass-through design

Q I love the high ground clearance for roots, rocks, ruts and other unexpected obstacles but does it influence stability?

Propel EV’s engineers sought to build the ultimate off road board with an industry best pass-through rate so that our products could go places without bottoming out where other boards can’t. However, our unique independent shock absorption system, along with the steering linkage system and self-balance stabilization system also provide unparalleled control and stability. While the tech is heavily convoluted, the experience for riders is highly intuitive.  Once our riders try our products they quickly become at ease on them.

For those who enjoy customization, we have applied a cushioning spring under the deck, which can be adjusted to better suit individual heights and weights.


QWhat kind of terrain can I ride on?

Propel EV’s X4S supports an absolutely massive 6.1”/155 mm ground clearance, which is almost double other all-terrain boards, letting you glide right over obstacles, and into some ruts without bumps or scratches. That makes it uniquely suited to multiple terrains; perfect for campsites, exploring mountain trails, gravel, hills, and more. With Propel EV products you can explore and enjoy scenery you’ve never experienced before while enjoying unrivaled comfort and agility.


Q: Can I do backflips with the board?

Unfortunately, we can’t support backlips. The X4S is designed for heavy-duty off-road riding. The net weight of the board is 19.5kg/42lb and 17.5kg/38.5lb for 4WD and 2WD respectively. Therefore, it’s not well-suited to aerial stunts.

Q Is it waterproof?

The X4S allows for riding in the snow; however, due to the unexpected track slips with the snow, we would recommend a safer ride under dryer conditions. In regards to the water splash-proof, although our components are sealed, there is still the possibility of water ingress, so we do not promise or recommend wading through the waters.

Q: Can children use it? What is the age range

In regards to the most suitable users of our products, we recommend users older than 14, so that the average payload would be sufficient for the riders to press on it, thus assisting better handling and turning. It's mainly for the purpose of the most optimal experience for the riders.

Q Do you have any color options?

At the moment, we offer a largely neutral color scheme so that the rider can introduce the color spash of their preference. We are considering color splash options to sell as accessories, including different spring colors and logo color options.

Q What are the load bearing parts of the board made of?

The load-bearing parts of the vehicle are made of aluminum alloy, including the upper and lower cantilever, mainly considering the strength and weight.
