The Jasion EB5 Roamer ST is a step-through electric commuter bike. The low frame makes mounting and dismounting easier. It has an 80mm front suspension fork, mechanical disc brakes front and rear, and 26 × 1.95-inch tires.
A 1,200W peak brushless hub motor provides up to 60 Nm of torque. The removable 48V 11Ah (528Wh) lithium-ion battery quick-releases for charging. Top speed is 28 MPH and maximum range is up to 62 miles. Speed and range depend on rider weight, terrain, riding mode, weather and battery condition, and the 62-mile range is not guaranteed in everyday riding.
The bike has five pedal-assist levels with a cadence sensor, plus a thumb throttle. A Shimano 7-speed drivetrain handles gearing. An LCD display shows riding information. Integrated left and right turn signals, a brake light and a rear light add visibility. A rear cargo rack adds carrying capacity, and a chain guard helps protect the chain and clothing from dirt and oil.
