HiKeep MA-S Review: A 40 MPH Electric Dirt Bike With Pedals

A 40 MPH electric dirt bike with pedals? That's an unusual combination—and exactly what makes the HiKeep MA-S worth a closer look.

With a 4,000W peak motor, a 60V 40Ah battery, fat tires, and full suspension, the MA-S is built around performance-oriented riding. But unlike many electric dirt bikes that focus primarily on throttle-powered riding, the MA-S also includes pedals and a pedal-assist system.

So why combine bicycle-style pedals with a machine capable of reaching 40 MPH? And does that combination actually make sense for everyday riders?

Let's look beyond the headline specs and explore what the HiKeep MA-S offers, where it fits, and what buyers should consider before making a decision.

1. The 40 MPH Question: Why Does It Have Pedals?

The pedals are arguably the most interesting part of the MA-S design.

At speeds of up to 40 MPH, this isn't what most people imagine when they think of a conventional electric bicycle. The MA-S combines a high-power motor with a pedal-assist system and Shimano 7-speed gearing, giving riders the option to pedal with motor assistance rather than relying entirely on the throttle.

That combination may appeal to riders who want a more flexible riding experience. Pedal assist can help reduce reliance on throttle power in suitable conditions, although the actual energy savings depend on the riding mode, terrain, and how much effort the rider contributes.

There's an important distinction, however: pedals don't automatically make a high-powered electric vehicle a conventional street-legal e-bike. With a claimed top speed of 40 MPH and a 4,000W peak motor, the MA-S may fall outside standard e-bike classifications in many locations.

For buyers, the real question isn't simply whether a bike has pedals. It's how those pedals function, what riding modes are available, and where the vehicle can legally be used.

2. Motor Power and Speed: Built for More Than Casual Cruising

The HiKeep MA-S features a 3,000W rated motor with up to 4,000W peak power, with a claimed top speed of 40 MPH.

Those figures place it firmly in the high-powered end of the electric dirt bike market. For riders interested in recreational off-road riding, the motor output is a key part of the MA-S appeal.

Of course, maximum speed doesn't tell the whole story. Acceleration, braking, handling, and stability all matter when evaluating a powerful electric ride. Actual performance can also vary with rider weight, battery charge, terrain, and riding conditions.

Without controlled ride-test results, it's better to treat the advertised figures as a starting point rather than a complete picture of real-world performance.

3. A 2,400Wh Battery and a Claimed 160-Mile Range

Battery capacity is another major feature of the MA-S.

The 60V 40Ah battery provides 2,400Wh of energy, and HiKeep advertises a maximum range of up to 160 miles in Eco Assist mode.

That's an ambitious range figure, so context matters. Maximum range depends heavily on how the bike is ridden. Higher speeds, steep climbs, heavier loads, low temperatures, and frequent throttle use can all reduce the distance available from a single charge.

Riders planning longer trips should therefore consider their expected riding style rather than assuming they'll achieve the maximum advertised range.

The pedal-assist system gives riders another way to use the bike, potentially improving efficiency when conditions and effort levels allow. Still, actual range should be verified through real-world testing under clearly described conditions.

4. Fat Tires, Full Suspension, and Off-Road Capability

Motor power may grab attention, but the equipment around it matters just as much.

The MA-S comes with 20 × 4.0-inch fat tires and a six-point full-suspension system. The wide tires are designed for traction across varied surfaces, while the suspension is intended to help manage bumps and uneven ground.

These features make the bike worth considering for riders interested in dirt paths, gravel, and recreational off-road environments.

However, specifications alone can't establish how well a bike handles technical trails or rough terrain. Tire pressure, suspension setup, braking performance, and rider skill all influence the experience. A genuine hands-on review should examine these factors rather than assuming that fat tires and full suspension automatically guarantee superior handling.

The MA-S also weighs approximately 95.2 pounds (43.1 kg). That's an important practical consideration. Although a heavy frame may suit a performance-focused design, it can make lifting, transporting, and maneuvering the bike more difficult when the motor isn't helping.

5. Smart Features Beyond the Motor

The MA-S also includes technology designed to make access and riding more convenient:

APP connectivity: Supports compatible smart functions.

NFC access: Offers a keyless access option.

LCD display: Provides riding information.

Shimano 7-speed gearing: Adds flexibility when pedaling.

These features help distinguish the MA-S from simpler electric bikes. Buyers should still check the current product specifications to confirm the exact functions available on their selected configuration.

6. Who Is the HiKeep MA-S For?

The MA-S may appeal most to riders looking for a powerful, off-road-oriented electric ride with a distinctive pedal-equipped design.

Its combination of motor output, battery capacity, fat tires, suspension, and pedal assist offers several features to compare when shopping for an electric dirt bike.

It may be less suitable for someone who simply needs a lightweight commuter bicycle. Its weight, high performance, and legal classification deserve careful consideration, especially if the intended use involves public roads or shared bike paths.

Before buying, consider three questions:

Where will you ride? Check whether the bike is permitted on your intended trails, roads, or riding areas.

How much range do you actually need? Compare your expected riding conditions with the advertised Eco Assist maximum.

Do you need the pedals? Understand how the pedal-assist system works and whether it suits your preferred riding style.

These questions are more useful than choosing a bike based on top speed alone.

Final Verdict: Is the HiKeep MA-S Worth Considering?

The HiKeep MA-S stands out because it combines the performance-focused design of an electric dirt bike with pedals and pedal assist—a combination that naturally raises questions about how the vehicle is meant to be used.

Its headline specifications are notable: up to 4,000W peak power, a claimed 40 MPH top speed, a 2,400Wh battery, 20 × 4.0-inch fat tires, and full suspension.

But the most useful buying decision comes down to more than numbers. Real-world range, braking, handling, comfort, weight, and local riding regulations all deserve attention. Independent testing would help establish how the bike performs beyond its advertised specifications.

For riders seeking a powerful electric ride with off-road-focused equipment and a pedal-equipped design, the MA-S is worth exploring. For commuters, it's especially important to verify that the bike's performance and classification match their intended use.

The pedals may be what gets your attention. The real question is whether the entire package fits the way you want to ride.
