E-Lines combine our strongest rim, the Mainline with stiffer, more torque-resistant rear spokes to deliver the power transfer, lateral stiffness, and durability demanded by E-Bike applications.  Like our Mainline wheels, E-Lines are backed by our Lifetime Guarantee.

Built for the rowdiest conditions, E-Lines are laterally, vertically, and torsionally stiff featuring a deep profile and robust cross-section designed to support the most aggressive tires.

Ride quality is tuned & improved through the use of SPM™ straight-pull hubs and 28 spokes per wheel, laced three-cross (while straight-pull hubs from many other hub makers count the spoke lobe as one of the cross points, SPM™ hubs are truly 3x, maximizing torsional strength) . The front wheel employs the same D-Lite Spokes as the Mainline to help mute small-bump chatter, While the rear wheel utilizes, thicker gauge, Sapim Race spokes to prevent "wind-up" that can result from the higher torque output created by an electric motor.  

The 34mm internal width of the E-line is ideal for tires ranging from 2.4" to 3" When paired with a 2.5" (or Maxxis WT) tire, E-Lines deliver the best traction/power transfer and most capable tracking in high speed chunk and hard cornering of any wheel we build.

Performance by design

The Difference is in the Details

At RF, we're obsessed with the belief that the "whole" should be greater than the sum of its parts.  It's why we build our wheels in-house, by hand.  It's also what leads us to design and manufacture almost all of the components that we use to build our complete wheels.  From hubs & rims, to tubeless tape & valves, we design each and every part to work together flawlessly as well as to excel individually.

I can't believe how much I've enjoyed these Livewire wheels...I'm glad I was introduced to this small, SoCal company because these cross-country wheels have been a revelation to me!  MTBR.com Gear of the Year
