Step-Through frame
Many people associate the step-through bicycle as being for women, however, they are convenient for any gender. The big advantage of step-through bikes is that they make it easier and much more comfortable to mount the bike. Your feet will be able to touch the ground and there are no worries about losing your balance and possibly falling while trying to get on it.
Powerful 750W motor
The powerful hub-drive motor features 750 watts of power and 80Nm of torque. This allows you to span cities, climb hills, and explore places you want to go with ease.
Hydraulic disc brakes and fat tires
The hydraulic disc brakes supply firm, safe and smooth stopping power, and get extra traction from the 4" Fat Tires. Choose 27.5×3 MTB wheels for less drag and a great commute on and off-road.
Drivetrain
From climbing hills to holding maximum speed on the flats, the Shimano 9-speed drivetrain has you covered.
LCD display
The LCD Display shows you all kinds of important information about your ride including speed, battery life, range, odometer, pedal assist level, and more.
RST guide suspension fork
The RST Guide fork provides 80mm of traveling pre-load, lockout, and rebound adjustability.
Integrated headlight
A bright LED will light your way when the sun goes down. It's powered by the bike's battery and can be turned on/off with a button on the handlebar control pad.
Rear Light
The bright rear light helps you ride with more confidence at night.
