Is the Jasion EB5 Ultra worth it?

It offers a lot for the money: a 1040Wh battery, 750W motor, hydraulic brakes, and rack, fenders, and lights included. It suits riders who want range and fat-tire capability more than a light, nimble bike.

What real-world range should I expect?

The 90-mile figure assumes low assist and ideal conditions. Expect meaningfully less at higher assist, in cold weather, or on hills, and plan charging around that.

Can I ride it without the motor?

Yes, but it is heavy with fat tires, so unassisted pedaling is tiring. Treat the motor as the primary power source.

Is it legal where I ride?

It is a Class 3 bike with a 28 MPH top speed, which some trails and states restrict. Check local rules before riding on shared paths.

What comes in the box?

The bike ships with the battery, charger, mirror, phone holder, fenders, rear rack, headlight, taillight, and kickstand. Assembly of major parts is typically required.

Our take on the Jasion EB5 Ultra

The Jasion EB5 Ultra is a fat-tire electric mountain bike with a 750W rear hub motor, a 52V 20Ah (1040Wh) removable battery, and a Class 3 top speed of 28 MPH. It pairs 26 x 4.0-inch tires with a reinforced fork and a 160 mm rear shock, plus hydraulic disc brakes, a 7-speed drivetrain, throttle, cruise control, and walk assist. Practical extras include full fenders, a rear rack, a headlight, a brake-activated taillight, and a kickstand. It is a heavy, long-range trail bike rather than a light commuter.

About the Jasion EB5 Ultra

Description: Go farther on mountain trails and spend less time charging with the Jasion EB5 Ultra electric mountain bike for adults. Built primarily for mountain riding, gravel paths, snow, sand, and outdoor recreation, this long-range fat tire e-bike combines a 750W rated brushless rear hub motor with speeds up to 28 MPH and at least 75 Nm of torque for responsive acceleration and climbing support. Its removable 52V 20Ah / 1040Wh lithium-ion battery delivers up to 90 miles of manufacturer-rated range under suitable conditions, helping riders enjoy extended trail rides, longer commutes, and multi-stop outings with fewer charging interruptions. The 26 x 4.0-inch fat tires provide a wide contact patch for improved traction across uneven terrain, while the reinforced front fork and 160 mm mid-mounted rear shock help absorb bumps for a more controlled and comfortable ride. Front and rear hydraulic disc brakes support confident stopping, while the 7-speed drivetrain, selectable 3- or 5-level pedal assist, throttle, cruise control, walk assist, and LCD speedometer give riders flexible control on changing terrain. Full fenders, a rear rack, front headlight, brake-activated taillight, and kickstand add practical convenience to this capable electric mountain bike.
