Technology
Intuitive Controller
The integrated top tube controller lets you turn the system on, select your assist level and see your battery charge, all at the touch of a button, keeping your handlebars clean and uncluttered.
Dialed Endurance Fit
Offers a perfectly balanced riding position: upright enough for comfort over the long haul and control when tackling off-road terrain, yet still low and forward enough for speedy efficiency.
Big Tire Clearance
Plenty of room, even with big 700x42mm tires.
Easy Charge
A simple to use, easy access charging port makes topping up a breeze. Or, plug in the optional range extender for a total battery capacity of 450Wh and take your rides even farther.
