Fix the two big positions
Begin with the wheel centres and compare their distance apart with the wheel diameter. Observe the angle at which you see each wheel; the shapes may be ellipses rather than circles. Place their lowest contact points on the same ground plane. If those relationships are wrong, beautifully drawn handlebars will only make the disagreement easier to inspect.
Look through the frame
Treat the triangular spaces within the frame as shapes. Draw one gap, then the bars that define it. Notice which parts overlap and which disappear behind other components. Simplify the chain, spokes and cables into a few selected marks. A bicycle can be readable without reproducing every wire. You are making a sketch, not assembling a machine from a particularly unhelpful instruction leaflet.
Give the whole thing a gesture
A bicycle leaning against a wall has a stance. Compare the saddle, handlebar and frame angle as one arrangement. Use a darker contact or cast shadow to connect it with the surroundings. If it is a small part of a street view, retain the wheel relationship and a convincing diagonal, then let the rest remain suggested. Save a separate close study for the mechanical details that interest you.

Take it to the page.
- Mark wheel centres and contact points for one stationary bicycle.
- Draw the main negative spaces inside its frame.
- Add only the lines needed to explain its lean and overlaps.
Look back: Would the frame still read if the spokes disappeared?
