ROTHBIKE FITCheck eligibility

Guided online bike fit

Four simple steps from setup to real rides.

Roth guides you to place your phone, record one side view twice without moving it, try one measured change you can undo, and evaluate it on real rides.

The complete loop

One clear next step at a time.

01

PREPARE

Get the phone ready before pressing record.

Roth shows the one setup correction that matters most. Recording begins only after the required checks pass.

CAMERA SETUP CHECK4 / 5 ready
  • Bike secure on an indoor stand or rollersReady
  • Full rider and bike in frameReady
  • Main camera on the back of the phoneReady
  • Phone straight and levelMove left
  • Clear light and steady pedalingReady
02

COMPARE

Repeat one side video without moving the phone.

The repeat recording is not busywork. Roth checks whether the same camera position and riding setup produce a consistent result.

03

CHANGE

Make one small change you can undo.

Your result shows what was noticed, why one change comes first, what to measure, what warnings apply, and how to return to your starting position.

CHECK RIDES

Learn what happens beyond the indoor setup.

Short, medium, and normal-duration rides reveal whether an observation holds when fatigue, terrain, and real riding time enter the picture.

A useful stop is a result

If the information is not clear, Roth stops.

  • Video is unclear or the two side recordings disagree
  • Symptoms worsen or control is affected
  • The bike cannot make the change safely
  • The situation needs a fitter, mechanic, or healthcare professional
