Descriptions

ERB Mountain Bike Frame with an innovative mid-frame suspension that actually delivers 100% of your pedal energy 100% of the time. Two short, incredibly tough composite rods that lie within the frame just behind the seat mount, allow the frame to absorb shock and vibration. The stainless steel cable you see can support 2500 lbs. The cable is attached to an extremely stiff vanadium coil spring that is attached under the head tube. The cable segment and the rods work seamlessly together to deliver a more favorable riding condition.
Designed originally as a 26” mountain bike these frames are extremely durable and a blast to ride.

A Triple Threat

29 wheel compatible700c Urban Commuter

Smart and Simple is what's behind the Energy Return Bicycle.
ERB's Energy Return System gives you a mechanical pedaling advantage by storing and releasing energy with every pedal stroke.
Along with pedal power transfer that is even better than on rigid frame bikes, on road or off, you get a smoother ride with unmatched handling.
The precisely machined Composite rods allow the frame to move slightly up and down helping the bike maintain superior traction and providing a smoother ride. Fastened side by side, the two incredibly resilient and durable rods work together adding comfort, control and performance. The rapid response coil spring is what gives the ERB the energy return near the end of your power stroke. The vanadium coil spring coupled to the stainless steel cable is like the heart of the Energy Return System. These springs are the same as those used in industries where springs are required to respond hundreds of thousands and into the millions of cycles under extremely heavy loads. That means your spring will literally last you FOREVER. Not only does the spring return energy, it is also what controls the amount of travel in the suspension and what continually pulls the wheels to the ground quickly and firmly after slamming bumps.
