The GT73 is a mid-range electric dirt bike built for trail riding and light off-road use

The GT73 is an electric dirt bike manufactured by Goplus, a company that makes consumer outdoor equipment and recreational vehicles. It sits in the mid-price segment — typically between $400 and $600 depending on the retailer and any current discounts. The bike is designed for recreational riders on trails, packed dirt, and light off-road terrain, not for racing or extreme downhill use.

The GT73 runs on a rechargeable lithium-ion battery and uses a hub motor mounted in the rear wheel. It has a seat height of around 28 inches, making it accessible for riders of varying heights, and a maximum weight capacity of roughly 220 pounds. The frame is steel, and the bike comes with front and rear disc brakes, suspension forks, and all-terrain tires.

Because it is an electric bike rather than a gas-powered dirt bike, it produces no emissions, requires no fuel, and generates minimal noise — a practical advantage if you ride on private land or in areas with noise restrictions. The trade-off is that battery range and power output are lower than what you would get from a gas engine of similar price.

Key Takeaways

  • The GT73 is a budget-friendly electric dirt bike best suited for casual trail riding and light off-road use, not racing or steep terrain.
  • Battery range is typically 20 to 30 miles per charge under normal riding conditions, depending on terrain, rider weight, and throttle use.
  • A full charge takes 4 to 6 hours using the standard charger that comes with the bike.
  • The GT73 requires basic maintenance — tire pressure checks, brake pad inspection, and battery care — but far less than a gas-powered dirt bike.
  • Assembly is required when the bike arrives; most riders need 1 to 2 hours and basic tools to complete it.

Battery range and charging time

The GT73 battery is rated for a range of 20 to 30 miles on a single charge under typical riding conditions. This range varies based on several factors: your weight, the terrain (flat ground gives longer range than hills), how much throttle you use, and the battery's age. A new battery will perform better than one that has been charged and discharged hundreds of times.

The standard charger supplied with the GT73 takes 4 to 6 hours to fully charge the battery from empty. Some owners purchase a faster charger separately, which can reduce charging time to 2 to 3 hours, though this may shorten the battery's overall lifespan over time. Most riders charge overnight or between riding sessions.

If you plan to ride for more than 30 miles in a single day, you will need to either charge mid-ride (if you have access to an outlet) or purchase a second battery. A spare battery typically costs $150 to $250 and allows you to swap in a fresh one without waiting for a charge.

Motor power and speed

The GT73 is equipped with a 500-watt hub motor in the rear wheel. This motor delivers moderate acceleration and a top speed of around 25 to 30 miles per hour, depending on terrain and rider weight. On flat ground with a lighter rider, you may reach the higher end of that range; on hills or with a heavier rider, speed will be lower.

The motor is direct-drive, meaning it is always engaged when the bike is powered on. There is no clutch or transmission to shift. You control speed using a twist throttle on the handlebar, similar to a motorcycle or scooter. The motor has no pedals — the GT73 is a throttle-only electric bike, not a pedal-information model.

For comparison, a gas-powered dirt bike in the same price range typically has a higher top speed and better hill-climbing ability, but the GT73's quieter operation and lower maintenance often make it preferable for recreational riders on private property or in noise-sensitive areas.

Maintenance and battery care

The GT73 requires far less routine maintenance than a gas dirt bike. You do not need to change oil, replace spark plugs, or maintain a carburetor. The main maintenance tasks are checking tire pressure (typically 20 to 25 PSI), inspecting brake pads for wear, and keeping the chain clean and lubricated if your model has a chain drive.

Battery care is the most important part of ownership. Lithium-ion batteries last longer when they are not fully drained on every ride. Ideally, you should recharge when the battery reaches 20 to 30 percent capacity rather than waiting until it is completely empty. Avoid leaving the battery in extreme heat or cold for extended periods, as temperature affects battery chemistry and lifespan.

Most GT73 batteries are rated for 500 to 1,000 charge cycles before capacity begins to noticeably decline. At an average of 25 miles per charge, that translates to roughly 12,500 to 25,000 miles of riding before you would consider replacing the battery. Replacement batteries are available from Goplus and third-party sellers.

Assembly and setup

The GT73 arrives partially assembled in a box. You will need to attach the handlebars, front wheel, pedals (if included), and seat. Most owners complete assembly in 1 to 2 hours using basic tools: a wrench set, a screwdriver, and an Allen key set. The instruction manual walks through each step, though some owners find online video guides helpful for clarification.

After assembly, you should check that the brakes are properly adjusted, the wheels spin freely, and all bolts are tight. The first charge should run for the full 4 to 6 hours to properly condition the new battery. Some owners report that the bike feels sluggish until after the first few charge cycles.

If you are not comfortable assembling the bike yourself, some retailers offer assembly services for a fee, typically $50 to $100. Local bike shops may also assemble it if you bring it to them, though not all shops are familiar with electric bikes.

Terrain and weight limits

The GT73 is designed for packed dirt, light trails, and flat to gently rolling terrain. It is not built for steep downhill riding, rocky mountain trails, or mud. The suspension is basic — a front fork with limited travel — and the frame is not reinforced for extreme impacts. Pushing the bike beyond its intended use can damage the frame or motor.

The maximum weight capacity is approximately 220 pounds. This includes the rider's body weight plus any gear or cargo. Exceeding this limit stresses the motor, battery, and frame, reducing their lifespan and potentially causing failure. If you weigh close to or above 220 pounds, the bike's performance will be noticeably reduced, especially on hills.

Riders under 150 pounds will see the best performance and range. Heavier riders should expect shorter range, slower acceleration, and reduced top speed. Some owners in the 200+ pound range report that the GT73 struggles on any incline steeper than a gentle slope.

Where to buy and warranty

The GT73 is sold primarily through online retailers including Amazon, Walmart, and Goplus's own website. Prices vary by retailer and season, typically ranging from $400 to $600. Some retailers offer free shipping; others charge a delivery fee. Because the bike arrives in a box requiring assembly, shipping costs are often higher than for smaller items.

Goplus typically includes a one-year manufacturer's warranty covering defects in materials and workmanship. This warranty does not cover damage from misuse, accidents, or normal wear. The battery is sometimes covered under a separate, shorter warranty — often 6 months. Read the warranty terms carefully before purchase, as they vary by retailer and region.

Return policies also vary. Most online retailers allow returns within 30 days if the bike is unused and in original condition. Once assembled and ridden, returns become more difficult. Check the specific retailer's policy before ordering.

Frequently Asked Questions

Can I ride the GT73 in the rain?

The GT73 has basic water resistance, but it is not waterproof. Light rain is generally fine, but you should avoid riding through deep water or heavy downpours. After riding in wet conditions, dry the bike and let it sit before charging. Water can damage the motor and electrical connections if it enters the wrong places.

What is the difference between the GT73 and other budget electric dirt bikes?

The GT73 competes with models like the MotoTec and Minimotors brands in the same price range. The main differences are motor power (500 watts is mid-range), battery capacity, and frame durability. The GT73 is known for being reliable for casual use, though it is not the most powerful or fastest option at its price point.

Can I upgrade the battery or motor?

Some owners have replaced the battery with a higher-capacity unit from third-party sellers, though this is not officially supported by Goplus and may void the warranty. Motor upgrades are more difficult because the motor is integrated into the rear wheel hub. Most owners do not attempt this.

How long does the GT73 battery last before it needs replacement?

A typical GT73 battery lasts 500 to 1,000 charge cycles, which translates to roughly 2 to 4 years of regular recreational use. After that, capacity declines noticeably. Replacement batteries cost $150 to $250 and are available from Goplus and aftermarket sellers.

Is the GT73 street-legal?

Street legality depends on your state and local laws. Most states classify electric bikes under 750 watts as legal for certain paths and roads, but rules vary widely. Check your local regulations before riding on public streets or bike paths. On private property, there are no legal restrictions.
