    How Does BodyFloat™ work?

    Firstly, with our design you are able to maintain a smooth, comfortable and efficient pedal stroke without bounce, flex or wasted energy. Our non-damped spring design allows for the natural vertical compliance necessary to encourage an efficient pedal stroke. It does this intuitively with your body weight and movement to allow for circular and efficient pedaling.
    Secondly, our design allows the system to truly isolate you from the terrain below, greatly reducing the amplitude of surface vibrations and small bumps, thus making your ride more comfortable.


    Why no damping?

    Good question...and this is the genius of BodyFloat™. Damping slows frequency response by definition. No damping allows for the best possible isolation of the power plant (ie: you...the motor) and allows for the best transmission of energy into forward motion. So you can be more comfortable, conserve more energy and put that energy into getting you from A to B quicker and more comfortably.

    There are two small end-range dampers in the BodyFloat™. A small top-out elastomer and a progressive bottom-out elastomer. These two small elastomers work to soften the endpoints of your specific travel range.

    How much travel does it have?

    Up to 1.5" (38mm) of true vertical travel, pre-loadable down to less than 1/4" (6.4mm) if desired. Somewhere in the middle is your ideal 'sweet spot' that works best for you and your needs. Just like fine tuning a car or motorbike suspension; performance and comfort can only be maximized once the suspension is tuned for all the variables.

    What is the "Sweet Spot"?

    The 'sweet spot' is the ideal combination of spring rate and pre-load that allows the rider to be most effectively isolated from the terrain below without negative movement or action. Your 'sweet spot' is easy to find and easy to change based on your weight, riding style, bike and selected terrain.

    What is "pre-load"?

    Pre-load refers to the force applied to spring component before external loads, such as rider weight, are applied. For instance: on a comfort based bike you may want less pre-load offering a more plush feel. For performance, add some pre-load to maximize efficiency and minimize travel. Adjusting pre-load can be done on the fly with the simple turn of the pre-load hex bolt located on the rear of the unit.

    Can I adjust the springs?

    Yes! Adjustment of the spring is easy. BodyFloat™ comes pre-configured based on your weight and riding characteristics. As mentioned above, you adjust the spring with the pre-load screw. This reduces the effective travel of the unit. If you find that you often bottom-out or it's too stiff, you can change the spring out with a spring of a higher or lower spring rate. This is done by removing the lower spring/spring guide and replacing the spring with one that better suits you.

    How and why to get additional springs?

    Swapping different springs allows you to customize your BodyFloat™ to your needs. You may prefer stiffer springs for a more upright position, carrying a messenger bag/pack or for less isolation. Use a lighter spring for more plushness and/or with more pre-load, for high performance applications like racing or stationary bikes. Springs are available for sale directly through our website and at retailers.

    What is its size ?

    The Aluminum model 2.0 comes in a 350mm length. The Carbon model 3.0 is available in 330mm and 380mm lengths. The Titanium model 3.0 is available in limited quantities in a 450mm length.

    All models have a post diameter of 27.2mm.

    How much does it weigh?

    The weights are as follows:

    • Model 2.0 - 350mm Aluminum = 493g
    • Model 3.0 - 330mm Carbon = 428g
    • Model 3.0 - 380mm Carbon = 465g
    • Model 3.0 - 420mm Titanium = 548g

    What is the difference between the 2.0 and 3.0 models?

    The difference is in the post material. the 2.0 comes in Aluminum and the 3.0 comes in either Carbon or Titanium. The top mechanism is the same for both.

    Will BodyFloat™ fit my bike?

    BodyFloat™ is designed to work on just about any bike with a round seatpost of at least a 27.2mm diameter. BodyFloat™ also works with any standard twin rail bike saddle. It is currently offered in 27.2mm seat post diameter, with shims available for larger sizes. We are not currently offering the BodyFloat™ with an aero or non-round post due to the many specialized sizes and shapes on the market.

    What is the rider weight range?

    BodyFloat™ is designed to work with riders from 100 to 260 lbs. (45 to 118 kg.) While we have had heavier riders successfully tune and use our product, we cannot honor the warranty past 260lbs.

    How much clearance is needed between my bike frame and the saddle?

    The BodyFloat™ requires a minimum of 120mm and a maximum of 250mm (as measured from the saddle rails to the top of the seat tube) to work effectively.

    Where is it made?

    We are currently producing them in our Bellingham, WA facility.

    When will my BodyFloat™ be available?

    The BodyFloat™ is available now!
