Teodor and Anjali watch a first lap

Teodor & Anjali — a 17-year-old who rides the track after school and helps new riders

The idea in play: push your weight down only on the back of a roller, where the wheel runs downhill.

A new rider pushes down hard on every roller, up and down alike, and runs out of speed by the fourth roller. "I am working harder than anyone here," she says, "and I am the slowest."

Teodor: a push down while the wheel runs down the back of a roller turns your weight into speed along the track.

Anjali: the same push on the way up a roller fights the slope, so it brakes you. On the way up, let the bike come up under you.

What should she change on her next lap?

The people at the track

  • Solveig built the track, and asks one question: where does the speed come from?
  • Teodor pushes down only on the back of each roller, running downhill.
  • Anjali lets the bike come up on the way up a roller, and never pushes there.
  • Joon tried pedalling on the rollers and found pumping faster.
  • Sefa carries speed round a banked turn by leaning in.
  • Zainab spaces the rollers so a rhythm exists at all.
  • Mateus reads the speed trace after every ride and points at the push that paid.
  • Liesel walks every new line before she rides it.
  • Emeka knows where the speed leaks away: tyres and the surface.
  • Thandiwe designs the easier line for someone on their first lap.
  • Caio trades height for speed and back again, and keeps count of both.
