Jasion EM1 Ebike

The Jasion EM1 is a moped-style fat tire electric bike designed for riders who need more range, more payload, and more capability than a standard e-bike delivers. Key features include:

• Moped-inspired frame with full suspension
• Dual 48V 15Ah battery system (720Wh × 2)
• 250W brushless motor with 65 N·m torque
• 20 × 4.0" fat tires for all-terrain grip
• 200 kg maximum load capacity
• Up to 150 km range per charge

It is positioned as the long-distance, heavy-duty flagship of the Jasion e-bike family.

The Jasion EM1 officially launches on 21 September 2026 on jasionbikes.eu. Full specifications and product details are already available on the EM1 product page.

The EM1 is equipped with a dual battery system — two 48V 15Ah packs (720Wh each) — for a total energy capacity of 1440Wh. The official maximum range is up to 150 km.

Real-world range depends on:

• Rider weight and cargo
• Terrain gradient and surface type
• Pedal-assist level (PAS 1–5)
• Ambient temperature and wind
• Frequency of throttle / motor starts

Even at higher assist levels, the EM1 comfortably covers 20–30 km one-way commutes on a single charge.

Yes. The EM1 is fully compliant with EU EPAC (Electrically Power Assisted Cycle) regulations:

• Motor: 250W continuous-rated brushless motor
• Max assisted speed: 25 km/h

The EM1 delivers 65 N·m of torque through a high-efficiency brushless motor, paired with 5 levels of pedal assist (PAS 1–5).Hill-climbing tips:Use PAS 3–4 for short, steep climbsUse PAS 2–3 for long inclines (better range)Start pedalling before engaging the highest assist level to protect the drivetrain

A single 48V 15Ah battery charges from 0 to 100% in approximately 5–6 hours.

The EM1 supports a maximum payload of 200 kg, making it the strongest model in the Jasion lineup. This opens the door to riders and uses that standard e-bikes can't serve well:

Riders above typical e-bike weight limits

Grocery runs, market hauls, and shopping trips

Carrying a passenger, pet, or backpack

Camera gear, camping kit, or work equipment

Touring with panniers and rear cargo

The EM1 is designed for riders between 165 cm and 195 cm tall.

The EM1 features 2-piston hydraulic disc brakes with a built-in power-off function. Advantages over mechanical brakes:

• Stronger, more consistent stopping power — less fade on long descents
• Better wet-weather performance — water is shed from the rotor surface
• Power-off safety — the motor automatically cuts when you brake, preventing unintended acceleration
• Lower maintenance — self-adjusting pads mean less frequent tuning

This makes the EM1 a confident choice for mountainous routes, rainy commutes, and stop-and-go city traffic.

Yes — the EM1's electrical components (battery, motor, and controller) are sealed to a level suitable for everyday riding in light to moderate rain. Best practices:

• ✅ Riding in light rain or on wet roads
• ✅ Riding through small puddles (water below battery level)
• ❌ Do not submerge the battery or motor
• ❌ Do not pressure-wash the bike
• ❌ After wet rides, dry the battery compartment and connectors with a clean cloth
