Electric vs Gas Dirt Bikes: Power, Cost and Maintenance

The dirt bike market now runs two full ladders in parallel. Here is how they compare at each step, using the models documented in the HIGHPER catalogue.

Ten years ago the electric dirt bike was a toy-class novelty. In this catalogue it is a full parallel range: electric models run from a 250W 24V kids' mini to the 8000W HP136E and HP131E, while the petrol range runs from the 52cc two-stroke to the 250cc four-stroke group. The best electric dirt bike for a given buyer is therefore not a single model — it is a step on a ladder, and the honest comparison is ladder against ladder.

Power and performance, step by step

At the bottom, the petrol starter is the 52cc two-stroke: 25–30 km/h, 19 kg, an automatic clutch. Its electric counterparts are the kids' minis (250W–500W class), similar in spirit — light, limited, supervised. In the middle, petrol offers the 125/140cc four-stroke group (maximum speed listed as 60–80, four gears) while electric offers the HP116E (33 km/h, around 20 km per charge) — the petrol table lists the higher maximum speed, while the electric table is the one that publishes a range figure; the two tables do not measure the same things, and the electric model's case at this step rests on simplicity.

At the top the positions reverse. The petrol flagship group on this site, the 250cc adult pit bike group, is a geared four-stroke with a 6.5L tank. The electric flagship HP136E lists a 95 km/h maximum speed and a 100 km range per charge from a 72V36Ah lithium battery; the HP131E lists 88 km/h and 65 km or more. The petrol flagship's table lists no maximum speed, so the tables support no like-for-like verdict at the top of the range; what they do show is the electric flagship publishing complete performance figures in a class where the petrol flagship's published data stops at gearing and tank size. All of these figures are the manufacturer's table figures, and real-world results vary with rider and terrain.

Running costs and maintenance

A petrol dirt bike's maintenance list is familiar: engine oil, air filter, spark plug, chain and sprockets, carburetor or fuel-system care, and periodic valve and clutch attention on four-strokes. An electric dirt bike deletes the engine list entirely — no oil, no plug, no filter, no fuel system — and keeps the shared list: chain (all three high-power electrics here are chain drive), brakes, tyres, suspension and bearings. Charging replaces fuelling: the HP137E's table lists a 6–7 hour charge, the HP131E's 7 hours, against minutes for a petrol refill.

Cost per hour of riding follows the same split. Electricity for a 2–3 kWh charge is cheap anywhere; petrol is priced per litre everywhere. Against that, a lithium battery is the electric bike's big wear item and its replacement cost is real, while a petrol engine's wear is spread across many small parts. Fleets that ride daily usually find electric cheaper to run; riders who ride rarely and far from power usually find petrol simpler to own.

Range, noise and access

Refuelling is the petrol bike's structural advantage: a tank refills in minutes and a jerry can extends the day again, while the electrics here list 20 km (HP116E) to 100 km (HP136E) per charge with hours to recharge. The petrol tables published on this site list no range figures, so no range verdict is offered — the documented difference is how each fuel is replenished, not a measured comparison of how far each bike travels. Noise is the electric bike's structural advantage: an electric dirt bike can be ridden in places where a two-stroke would end the venue — near housing, indoors, on shared land — and that access argument decides more purchases than any specification.

So the decision is situational, and both ladders deserve to exist. Choose petrol for refuel-anywhere use, geared-bike feel and the lowest purchase price at a given size. Choose electric for quiet access, minimal maintenance and instant throttle response. The electric and gas pages lay out both ladders with their tables; compare the steps, not the slogans.

Charging, battery care and the real cost split

Battery care is the electric ladder's one discipline: the high-power tables list charge times of 6–7 hours (HP137E) and 7 hours (HP131E), and lithium packs prefer partial, regular charging over deep discharge and long storage at full or empty. A home charger and a routine — ride, charge, ride — suits the electric bike's design centre; a bike stored for months needs its battery stored at partial charge, which is the single most common ownership mistake in the class. Petrol's equivalent discipline is fuel freshness and oil intervals; neither ladder is discipline-free, they just schedule it differently.

For training schools and rental fleets the split sharpens: electric bikes simplify supervision (no hot exhaust, no fuel handling, adjustable output on the documented HP-I42S-style controllers is a scooter feature, but the HP116E's automatic transmission makes the same point for young riders on dirt bikes), while petrol bikes simplify logistics on multi-day trail operations. The fleets that run both usually assign electric to the school and the yard, petrol to the trail — the ladders are complements at fleet level too.

The one-line summary

Petrol wins on refuelling and purchase price at a given size; electric wins on maintenance, noise, access and the fullest published performance figures at the documented top of this range. The ladders are parallel, so the practical method is to fix your size step first (starter, 125-class, or flagship), then choose the fuel that matches where and how the bike will actually be ridden. Both ladders, with every table, are on the dirt bike family page.
