Comparing HappyRun G300 Pro and Freego Nova 5? Both belong in the high-output 72V adult electric dirt-bike category, but they solve different buyer problems. The G300 Pro is a lower-cost hub-drive route into high-output riding, while the base Nova 5 offers a larger 40Ah pack and more powerful mid-drive off-road package at greater weight. This guide focuses on published model facts, ownership tradeoffs and intended terrain—not invented firsthand ride testing.
Quick verdict: G300 Pro for value, Nova 5 for the mid-drive platform
The HappyRun G300 Pro is the natural starting point for an adult rider who wants high-output 72V performance without committing to the more expensive mid-drive category. It uses a 3,000W rated rear hub drive with up to 6,500W advertised peak, a removable 72V 30Ah battery, and a published 136.8-pound bike weight.
The Freego Nova 5 is a more substantial off-road-focused mid-drive machine: 4,000W nominal, up to 8,000W peak, 72V 40Ah battery, forged aluminum-alloy frame and approximately 159-pound weight. If the drivetrain design, larger energy reserve and hardware package are what you want, those features may justify the higher price. The two models should not be chosen only by a claimed top speed.
Published G300 Pro vs Nova 5 specifications at a glance
These figures come from the current WattWheelz model listings and manufacturers' published product specifications. They are not independently measured laboratory results or guaranteed performance on the same test course. Always compare the base Nova 5 to the base G300 Pro; the Nova 5 Pro is a materially different variant with its own motor and speed claims.
Both use a 72V nominal battery system, but the pack size and drivetrain are different. Wh (watt-hours) gives more context than amp-hours alone: 72 × 30 = 2,160Wh on the G300 Pro versus 72 × 40 = 2,880Wh on the base Nova 5. Higher stored energy does not directly predict the same percentage increase in range when load, gearing and power use vary.
| Specification | HappyRun G300 Pro | Freego Nova 5 (base) |
|---|---|---|
| Drive system | Rear hub motor | Mid-drive motor |
| Rated / peak output | 3,000W / 6,500W | 4,000W / 8,000W |
| Battery | 72V 30Ah / ~2,160Wh | 72V 40Ah / ~2,880Wh |
| Published top speed | Up to 50 mph | Up to 53 mph |
| Manufacturer range claim | Up to 70 miles | Approx. 40–70 miles |
| Bike weight | 136.8 lb | About 159 lb |
| Published load | 350 lb | About 264 lb |
| Front/rear brake rotor | 180mm / 203mm | 220mm / 200mm |
Why hub drive versus mid-drive is a bigger difference than peak watts
A hub motor drives the wheel directly through the rear wheel assembly. It has fewer bicycle-drivetrain power-transfer demands, but motor speed and wheel speed are linked. A mid-drive is positioned closer to the center of the bike and sends power through its final drive, with performance shaped by the motor, transmission configuration and controller. Not every e-moto mid-drive uses a normal bicycle chain and derailleur, so do not assume it shifts like a commuter e-bike.
The G300 Pro is a rear-hub system with single-speed gearing. Nova 5 is a higher-output mid-drive off-road platform. For some buyers, the mid-drive architecture and related suspension/brake package justify consideration more than a 3 mph headline speed advantage. For other buyers, those advantages are not relevant to the terrain they ride or their available budget.
Battery energy: does 2,880Wh mean one-third more riding?
The Nova 5 pack stores about 720Wh more nominal electrical energy than the G300 Pro's 2,160Wh pack—one-third more. That is a meaningful energy difference, but it does not guarantee one-third more distance. The Nova 5 may use more energy while accelerating or riding aggressively, and the machines do not share a verified real-world test protocol.
For additional battery context, see our 60V versus 72V dirt-bike voltage explainer. Both product pages use optimistic or broad published range language. The G300 Pro advertises up to 70 miles; Nova 5 around 40–70 miles depending on circumstances. Consider a route with climbs, soft soil and high throttle demand as a different task from gentle low-assist cruising. Protect a return-trip reserve rather than planning to use a full advertised maximum.
HappyRun G300 Pro: why its value positioning matters
The G300 Pro gives adult buyers 72V battery voltage, claimed 6,500W peak output, hydraulic brakes, an inverted front fork and 19-inch front/17-inch rear off-road motorcycle-style tires. It is not a lightweight commuter, yet its lower advertised purchase price can make the entry into high-output off-road riding less expensive than Nova 5.
The manufacturer lists a 31-inch seat height, rider-height guideline of 5 feet 4 inches to 6 feet 3 inches and 350-pound payload. Check the fit before ordering. For route planning, brake upkeep and ownership concerns, read our HappyRun G300 Pro review and the electric dirt bike buying guide.
Freego Nova 5: who benefits from the bigger chassis and powertrain
The base Nova 5 uses a published 4,000W nominal/8,000W peak mid-drive, 72V 40Ah removable battery and a forged aluminum-alloy frame with front and rear hydraulic suspension. WattWheelz lists four-piston hydraulic disc brakes, approximately 210mm front travel and 78mm rear travel for the base configuration. The manufacturer-published weight is around 159 pounds.
The 159-pound chassis is roughly 22 pounds heavier than the G300 Pro, yet the Nova's published payload figure is lower, around 264 pounds. Bigger output is not the same as bigger carrying capacity. Prioritize riding fit, handling and the real route instead of judging these bikes by peak wattage. When shopping the Nova 5 product page, explicitly select the base 'Nova 5' model, not 'Nova 5 Pro', for this comparison.
Nova 5 versus Nova 5 Pro: do not confuse the variants
WattWheelz presents Nova 5 and Nova 5 Pro as selectable model options under the Nova product family. The base Nova 5 is listed at 4,000W nominal, 8,000W peak and approximately 53 mph; the Nova 5 Pro is advertised at materially higher power and up to around 62 mph in manufacturer comparisons. Those figures are not interchangeable.
A product page that displays a higher-priced Pro option should not be used to justify a recommendation for the base Nova 5. Check the model selection, battery type, current stock, motor rating and the actual cart line item before checkout. This guide focuses on the base Nova 5 only.
Real off-road braking and suspension: what buyers should inspect
Both bikes have hydraulic disc braking but the published rotor sizes differ. HappyRun lists 180mm front and 203mm rear. WattWheelz lists 220mm front and 200mm rear for the Nova 5, with four-piston calipers. Larger rotors can affect heat capacity and leverage, but braking distance also depends on tire grip, rider weight, terrain, mechanical condition and rider skill.
Nova 5 lists a front hydraulic fork with approximately 210mm travel, while the G300 Pro advertises an inverted suspension system and a vertical rear shock. Evaluate suspension adjustment, replacement parts and dealer support for your terrain. Manufacturer specification alone does not prove that one machine is faster or more comfortable on your particular trail.
Handling and transport: neither bike is small
The G300 Pro at 136.8 pounds is already far heavier than a typical pedal-assist e-bike. Nova 5 is heavier at around 159 pounds. Those weights make parking, transporting and recovering a dropped bike substantially different from moving a commuter bicycle. Choose a transport carrier and loading equipment rated for the actual machine.
The seat height and standover also matter. A person may fit the manufacturer's height range but still struggle to balance a heavy bike on sloped, uneven ground. Consider your strength, protective equipment, intended riding area and ability to load the model into a truck or trailer safely.
Off-road legality: do not treat a high-power machine as a Class 2 bicycle
Both machines advertise off-road speeds far above the commonly used assisted-speed limits for ordinary electric bicycles. Public-road and trail access depends on jurisdiction, motor classification, registration rules, land-manager policies and actual configuration. A manufacturer-assigned 'class' display setting does not automatically create legal permission to use every road or bicycle path.
Before buying, check whether the property or trail permits the exact vehicle type. If your primary purpose is a legal city commute, compare appropriately classified pedal-assist e-bikes instead of assuming you can operate an e-moto anywhere a bicycle is allowed.
Maintenance and replacement-part planning
The G300 Pro's hub-drive arrangement and the Nova 5's mid-drive design can lead to different service demands, including controllers, final drive components and specialized motorcycle-style tires. Both machines will consume brake pads and tire tread faster under hard riding, especially on abrasive terrain. Confirm availability of the exact replacement parts.
Large lithium-ion packs also deserve careful ownership planning. Use only the manufacturer-approved charger and follow storage and charging temperatures. Inspect brake lines, rotor condition, chain or final-drive hardware and tires regularly. Use our battery care guide as a general starting point, but defer to the exact model manual on compatibility and service intervals.
Who should buy each one?
Choose G300 Pro first if you want a 72V adult electric dirt bike with a comparatively accessible purchase price, can handle its 136.8-pound weight, and are comfortable with a rear-hub system. Consider Nova 5 if you can justify a heavier 159-pound mid-drive machine and want the 2,880Wh pack, higher manufacturer output rating and its off-road component package.
If you are still unsure which performance tier is right, compare the 79Bike Falcon Pro as a premium third option. Our three-bike G300 Pro versus Freego X2 Pro versus Falcon Pro comparison adds a pedal-equipped and a premium alternative.

How to compare purchase value without being misled by promotions
Compare the exact selected variant and final checkout total rather than screenshots of different sales events. Price, free-shipping eligibility, warranty coverage and financing disclosures may change. The G300 Pro and Nova 5 can serve different budgets, but a temporary discount cannot resolve whether you need the larger battery or a different powertrain.
Confirm that a lower displayed price is for the single machine you intend to buy, not a two-bike combo or a Pro configuration. Read each manufacturer's written warranty and return terms and ask WattWheelz for confirmation when a spec sheet conflicts with a product selector.
A simple dirt-bike selection checklist
Write down the precise terrain and legal access, your height and preferred seat feel, the weight you can move safely, the range you need with a return reserve, and the complete delivered cost. Then compare rear-hub versus mid-drive service support and whether the listed payload suits you and your equipment.
If the answers point to a lighter, less-expensive entry into adult 72V dirt bikes, inspect HappyRun G300 Pro. If your route justifies a heavier, more expensive mid-drive and bigger battery, inspect Freego Nova 5. If neither works, use the adult electric dirt-bike buying collection and wider electric dirt bike selection to compare alternatives.
