Questions are welcome. No pressure, no bike jargon required.
The ride, not just the specs
FX is the bike we recommend for getting fit, running errands, and riding just because. It's light, comfortable, and easy to ride.
Whether it's a morning loop or a ride to the coffee shop, it makes it easy to get out the door.
What makes it special
Press the thumb throttle and go — whether you’re starting from a stop or climbing a hill, you’ll get a boost right when you need it. Plus, the throttle works with your assist level, so the extra support feels smooth, natural, and fun.
A rear brake light with integrated turn signals helps alert others of your next move, while the fork-mounted headlight turns with you to light the way around every corner.
The EasyMag charger uses a directionless magnetic connection to easily snap into place every time. LED lights clearly show your battery level at a glance, and the optional wall mount keeps your setup clean and ready to grab and go.
