A road we could bring into the lab.

I pitched the bicycle-testing treadmill, gained leadership approval and established the Woodway relationship to define specifications and develop the custom machine. I also presented the system to dealers.

My role

Developing the testing capability

My role connected the proposal, the specialist manufacturer and the equipment specifications. The road-molding work is also part of the project history documented in Trek’s published account.

The published sequence

From road surface to machine

The development team’s sequence as Trek published it. Team work, not a list of Reggie’s individual tasks.

  1. Molds taken from ride-test roads.Trek Bicycle, published development account
    01

    Make the molds

    Capture roads used in ride testing.

  2. The reproduced surface laid as a track.Trek Bicycle, published development account
    02

    Explore a concrete track

    Reproducing the surface still left variation in riding line, speed and conditions.

  3. Scanned surface geometry.Trek Bicycle, published development account
    03

    Scan the terrain

    Laser scans supplied digital geometry for consistent line selection.

  4. The rigid-slat running surface.Trek Bicycle, published development account
    04

    Evaluate the platform

    A drum proposal was judged insufficiently realistic; Woodway’s rigid slats offered another route.

  5. The bicycle-specific machine in development.Trek Bicycle, published development account
    05

    Develop the treadmill

    Trek and Woodway collaborated on the bicycle-specific machine.

The testing setup

What changed in the testing setup

Before: separate strengths

Road testing supplied realistic terrain. Laboratory testing supplied more consistent comparisons. Each had limitations.

After: another research tool

The custom treadmill added terrain replication under controlled conditions, with high-speed imaging available. Conventional lab and road testing continued.

A change in available capability, not a measured improvement.
