The Lowdown on High Performance

Lightning strikes again with the super light suspended R-84. The sub-3-pound frame is aerospace-grade carbon fiber, titanium, and oversized aluminum. The seat is positioned a bit lower than the P-38 and Phantom II for even more aerodynamic advantage.

Can this light bike climb hills? Better than any other recumbent. Take a look at the video on our Cyber Test Page. Because of its lightweight design and aero components, the R-84 will even outperform the F-40 in very hilly areas or on rides that are mostly climbing.

“This bike accelerates and climbs great!”
