Looking for a cheap electric dirt bike that doesn't sacrifice performance? Most budget options top out at 500W and struggle to hit 30MPH. The Jansno S50 is different — and at $1,849 (with a $150 coupon off $1,999), it delivers specs that rivals charge $3,000+ for.
Here's everything you need to know.
What Makes a Good Cheap Electric Dirt Bike?
Before we dive into the S50, let's talk about what separates a worthy budget electric dirt bike from a cheap one.
- Motor Power — Anything under 1000W will leave you struggling on hills. Look for 3000W or more for real off-road performance.
- Battery Quality — Lithium-ion batteries (especially ternary lithium) last longer and perform better than sealed lead-acid alternatives.
- Braking System — Hydraulic disc brakes are the gold standard. Mechanical brakes are a major downgrade, especially at high speeds.
- Waterproofing — If you're riding off-road, you'll hit mud, rain, and puddles. IP67 or higher is a must.
- Weight Capacity — Many budget bikes max out at 100kg. If you're a full-grown adult, that's a dealbreaker.
The S50 checks every single one of these boxes.

Motor & Speed
The S50 runs a 4000W brushless motor paired with a 72V system — this is the kind of setup you find on bikes twice the price. Three riding modes (40/60/80 KM/H) let beginners ease in before opening it up to full 50MPH performance.
Battery & Range
The 72V 30AH ternary lithium battery is a standout feature at this price point. Ternary lithium holds charge better in cold weather and has a longer lifespan than standard lithium-ion. Charge time is 6–8 hours from empty.
Safety & Braking
Hydraulic disc brakes bring the S50 to a stop in just 6 meters — critical when you're flying through trails at speed. Front and rear hydraulic damping suspension absorbs rough terrain and keeps you in control.
Waterproofing
IP68 is the highest common waterproof rating — meaning the S50 can handle full submersion, not just rain splashes. Ride through puddles, mud, and wet trails without worrying about electrical damage.
Who Is the Jansno S50 For?
The S50 is built for:
- Adult riders who need a bike that handles their weight (up to 330 lbs / 150 KG)
- Off-road enthusiasts who want real climbing ability and trail performance
- Budget-conscious buyers who refuse to compromise on power and safety
- First-time electric dirt bike owners who want a complete, ready-to-ride package
It's not a toy. It's not a kids' bike. It's a full-performance electric dirt bike priced for real people.
