How to Work
: How B3F Works

The B3F Seatpost incorporates the Formega, a '3-Way Stabilization' technology that allows the bike saddle to rotate together with the thigh and hip muscles in three-dimensional direction, significantly reducing friction between the saddle and the hip

Existing Bike Seatposts and Saddles

Problems with fixed saddles

Existing bike saddles are in fixed position. In this case, riders will feel discomfort, which is generated by pedaling on the fixed saddle, causing the interruption of pelvic movement. Also, riders feel pain and discomfort because of the impact from the ground deliverd to the pelvis diretly.
When a rider's right foot pushes downward, pelvis tilts to the right as the center of gravity moves to the right and left pelvic leaves the saddle at the same time. It reduces power output from pedalling because friction is generated from the inside thigh muscles trying to push the right-side of saddle towards back. Meanwhile, riders experience pelvic pain from left pelvic because the fixed saddle bumped against each other while pedalling from the left.

The problem of shock absorbing seatposts and saddles

Existing seatposts with dampers were designed to absorb impact from the ground by declining the whole saddle position. But dampers also absorb and reduce power transfer that needs to be deliverd to the pedal. And existing saddles with dampers can absorb impact from the road because of its inflection point of movement located at the back of saddles. But the dampers also absorb and reduce power output generated from pedalling.

When we walk, the width between our left and right foot is narrow, so when we step forward, our pelvis, knees and feet are aligned straight in the direction of gravity.
Pedals、the pelvis, knees and feet are not aligned in the direction of gravity. Causing the angle of the knee bends inside bcause the knee gets stressd. In this case pedaling can cause knee pain and reduce power output.

B3F Seatpost

The birth of a perfect solution

The B3F Seatpost is equipped with Formega. The patented technology with elastic rubber called 'Formega' which enables bike saddle to move in triaxis (X,Y,Z) from the center of the saddle. This patented technology resolves all power absorption problems when pedaling.

B3F 3-Way  
* Although the gap between pedalling is big, flexibility of Formega allows the saddle and pelvis move together. This allows pelvis, knees, and foot aligned to the direction of gravity and increases power without injuries.
* It allows extra safety to riders in cornering because it moves the center of gravity naturally either to the left or to the right.

1. When the crank arm rotates from 12 o'clock position to 3 o'clock position.
Rotating from Pedalling 12 to 03   When a person walks, the upper and lower body move forward simultaneously. So the pedalling is moving just like walking. When the foot position falls, the position of the hipbone moves from the rear of the saddle to the center of the saddle, causing the power of pedalling pass to the bike.
2. When the crank arm rotates from 3 o'clock position to 6 o'clock position.
Rotating from Pedalling 03 to 06   The power of pedalling reaches to the maximum output to deliver the whole bike to move forward and this causes body to move backwards, meanwhile the position of the hipbone moves to the back of the saddle again. The saddle tilts to the right with the body and the left pelvic bone stays on the saddle as the right foot pushes downward. When inner thigh muscles pushes the side of the saddle, the saddle rotates to the right and this reduces friction between the leg and the saddle, which increases power from pedalling. B3f seatpost has it's inflection point in the middle of the Formega which is designed to prevent absorbing power from pedaling. The elasticity of Formga allows the back of the saddle to move downward with riders weight so it prepares to bounce off to create more power.
3. When the crank arm rotates from 6 o'clock position to 9 o'clock position.
Rotating from Pedalling 06 to 09   AS the rider's body weight and the center of body moves to the left. The elasticity of Formga simultaneously bounces to create more power by lifting right pelvic bone when the pedalling starts on the left. This increased pedalling of power reduces muscle fatigue because less body energy is needed for pedalling. Also, rider are relieved from saddle pain because left pelvic bone and the saddle stayed together. And "From 12 o'clock position to 3 o'clock position" will connect the same movement.
4. When the crank arm rotates from 9 o'clock position to 12 o'clock position.
Rotating from Pedalling 09 to 12   Due to the elasticity of Formga, the occupant's weight naturally moves to the left. And "From 3 o'clock position to 6 o'clock position" will connect the same movement. Pedal operation ends with the left pedal and resumes from 1 starts.

Benefit of B3F

Reduction of Friction   Bounding Pedaling  
Reduction of Friction
Bounding Pedaling
The bike seat mounted on b3f significantly mini mizes friction and increases speed and reduce pain when the hip and bike seats move together. The bound pedalling created by the combination of elasticity of FORMEGA and triaxial movement of saddle helps increase power and speed of the bike. It also reduces muscle fatigue.
Prevent Wear on Clothes   Reduction of Fatigue  
Prevent Wear on Clothes
Reduction of Fatigue
The reduced friction minimizes the wear and tear on bike clothes. Moreover, it is economical since it is compatible with the existing bike seat rail already being used. Formega absorbs the vibrations and shocks created from the irregular road surface, minimizing pain and fatigue.
Cornering   Nose Down  
Nose Down
Because the bike seat moves accordingly with the user's center of gravity, the slant angle can be minimized during cornering, allowing for increased safety and speed (as pedaling while cornering becomes possible). If riders have done urgent breaking, when the bike stops but the rider moves forward by action of inertia. So it keeps a rider from rollover accidents by pressing Formega of the saddle forward with bodyweight of the rider.
