In an effort to generate quick distribution and product awareness, we have set aside a very limited number of frames at the incredible price of $299 (plus shipping). These frames are smoother riding than any rigid frame bikes on the market; and they are fast.

The Sling Shot Bicycle inventor, Mark Groendal is introducing a new, smoother riding, lighter weight  7005 Aluminum frame that is perfect for many of today’s riders. Mark's new Energy Return Bicycle company has no affiliation to or with the Sling Shot Bicycle Co.

You are looking at a 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.

Frame size & color
Set up your bike as an urban/commuter rocket ship with 29” wheels, disc brakes and 700c tires.The firm, mid-frame suspension reduces vibration and makes your ride to or through town quicker and more enjoyable.
Or set up your bike as a dirt-road/trail bike with 29" wheels, disc brakes and 700X35c cycle cross tires. The mid-frame suspension improves traction, reduces vibration and noticeably improves acceleration and ratchets up your overall speed. 
Finally set your bike up as a full on 26" mountain bike. The ERB suspension will help you climb hills better and faster than you ever thought possible. This frame delivers more of your precious pedal energy to the ground. All frames are equiped for disc brakes and we have some that also have bosses for V-brakes. Our frames are also set up so you can add a suspsnsion fork if you desire.

Composite Rods

Coil Spring Technology
BUY LIMITED TIME ONLY $299
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 .
