Jasion EB5 MAX 1500W Fat-Tire Performance E-Bike

The 30-second verdict

Jasion's answer to buyers who want the EB5 distribution model (Amazon-direct, returns through Prime, low price-to-spec ratio) but with serious power and fat-tire utility. The EB5 MAX takes the EB5 chassis philosophy and bolts on a 750W rated / 1500W peak rear hub, a 48V × 15Ah (720 Wh) battery, 26x4" fat tires, cruise control, fenders, rear rack, and Class 3 (28+ MPH) capability, making it Jasion's only Class 3 bike. The Amazon listing rates it 3 stars on a small sample of reviews (this is a newer SKU than the EB5's 2,283-review monster), so the long-term track record isn't established yet.

What you sacrifice for the bigger spec: 78-lb total weight (heavy enough that the carry-into-garage logistics matter), Jasion's 1-year warranty (vs 2 years on Heybike + Velotric), and cadence-sensor pedal assist (vs torque sensor on the $1,000+ DTC tier).

Power and battery

750W rated rear hub with 85 Nm torque (Jasion markets 1500W peak, a brief boost rather than sustained) is the right power tier for a Class 3 fat-tire bike. The motor pulls a 200-lb rider up sustained 7-8% grades in PAS 5 without obvious strain; the cadence-sensor pedal assist still switches power on/off rather than ramping smoothly, but at this power level there's enough headroom that the cadence-sensor character is less of a problem than it is on the 500W EB5.

The 720 Wh battery is in the same class as the Heybike Cityscape 2.0 and Vivi ACE07. Jasion claims up to 65 mi range; real-world fat-tire riding (PAS 3, 180-lb rider, mixed terrain, some Class 3 sprinting) lands at 30-40 mi per charge. Pure Class 3 sustained-28 MPH riding drops range to ~22 mi. Cold weather drops another 15-20%. Battery is removable for indoor charging, which matters at 78 lb.

Class 3, and what it changes

Class 3 is the meaningful spec difference from the rest of the Jasion catalog. 28 MPH pedal-assist (no throttle assist above 20 MPH) means real commuter speed on roads where you'd otherwise be passed by every car. The trade-off: Class 3 is banned from shared-use paths by default in many states, including Washington, Colorado, California (with the SB 1271 mandatory helmet requirement at all ages), and others. Check your state's rule before assuming you can take the EB5 MAX on the local greenway.

Some states are more permissive: Texas and Florida generally allow Class 3 on bike paths at the state level (local rules may differ). New York caps Class 3 at 25 MPH and restricts it to NYC. The EB5 MAX is the right bike if you want road-legal commuter speed; verify the path-access rule before you assume you can replace your existing trail bike with it.

Build, brakes, drivetrain

Hydraulic disc brakes front and rear (180mm rotors). Finally, a Jasion bike with hydraulic brakes. Front suspension fork is a basic spring fork (present, not adjustable, redundant on fat tires). 7-speed Shimano drivetrain, the universal Amazon e-bike groupset, replaceable at any shop. Front + rear lights wired to the battery; rear rack and fenders standard. Cruise control is included (throttle can be locked at the current speed for steady riding).

Jasion warranty: 1 year on motor and battery, 6 months on frame and components, shorter than Heybike (2 years frame/motor), Velotric (2 years), or Lectric (1 year frame/2 years drivetrain). Amazon's 30-day return window is the safety net. Customer support routes through Amazon Q&A + Jasion email.

Who should buy it

Buy this if you specifically need Class 3 (28 MPH) speed for road commuting AND fat-tire flotation for mixed-surface riding, if you want a 720 Wh battery on a Jasion-tier price ($899-1,099), or if you're upgrading from a Jasion EB5 and want to stay in the same brand ecosystem with a serious power bump. Skip this if you ride 100% smooth pavement (fat tires cost you 20-30% range and add 5+ lb of wheelset weight, so the Heybike Cityscape 2.0 is the better paved-Class-3 pick), if you live in a Class 3-restricted state and ride mostly on paths (the speed advantage is wasted), if you want 2-year warranty (spend up to Heybike / Velotric / Lectric), or if you want established review volume (the EB5 MAX is too new for the 2,283-review confidence the original EB5 has).
