Japan Bike Technique 2022 Tournament Composition

● Presentation

The presentation will be given in 10 minutes per team based on the concept, production technology, practicality, and design. There is a question and answer session by the referee for 5 minutes.

● Ride

This is an event where you can compete for your skills and ideas in search of a bicycle that allows you to enjoy a safe and comfortable trip.
(JBT2022 is not all about competing for speed and arrival order).

Emphasis is placed on the production policy of the bicycle itself and the “work” itself.
Weight is a big factor in the burden on the rider, so it is the key to scoring.
Set a hill climb section and set points (the specific weight is not so high).
For the downhill section, set the specified transit time.
Pass the section on time. A penalty will be imposed for early and late arrivals.

● RINKO demonstration

After the goal of the ride, will have a RINKO demonstration.
After the goal, disassemble the bicycle, pack it in a bag, and carry the loading equipment on your back to make it ready for RINKO.
In that state, get off the stage, walk the prescribed route, and return to the stage again.
After that, assemble the bicycle and load the equipment. Measure the time until you can ride.

If the rider is very tired, the frame builder or team representative may act on behalf of the RINKO demonstration only.

The ranking is calculated based on the measured time and used as a point.
