05 Audience points
Due to the influence of the new corona virus, the number of general visitors is small, so we have not adopted it.
06 Ride (Hill Climb Time Trial)

1 | 10 | GRAND BOIS ebike | 1:40:00 |
2 | 6 | GRAND BOIS | 1:45:00 |
3 | 9 | Panasonic | 1:48:00 |
This is a hill climb time trial with an altitude difference of 1,302m and a horizontal distance of 23km.
“GRAND BOIS ebike”, which makes full use of electric assist, is ranked first despite being a rider in 60s. “GRAND BOIS ebike” showed us the potential of an electrically assisted touring bicycle. “GRAND BOIS” by the same builder is second and they get 1st and 2nd finish. The third place was “Panasonic”, which seems to have slowed down the pace consideration of the later route.
07 Inspection after Ride
Verify the condition of the bicycle after riding all routes and deduct points for damage.
Probably because of the experience of the previous 2019 tournament, only 3 teams were detected to be damaged. It can be said that not only the weight reduction but also the high reliability was confirmed.
08a “Rinko” Time Trial
Ranking | Number | Team name | Time |
---|---|---|---|
1 | 9 | Panasonic | 0:10:00 |
2 | 1 | TODABASHI cycle works | 0:19:00 |
2 | 8 | NAGARA Self-build Bicycle Secret Research Institute | 0:19:00 |
Measure the time it takes to disassemble the bicycle and pack it in a “Rinko” bag, and the time it takes to take the disassembled bicycle out of the “Rinko” bag, assemble it, attach equipment, etc., and it is ready to run.
Taking advantage of the reflection of the 2019 tournament, “Panasonic” has a unique rear rack that doubles as a ”Rinko” rack, and as a result of the divisible fender specifications, it ranked first in an amazing time.
“Todabashi Cycle works” ranked second due to the effect of the bicycle with a unique “Rinko” mechanism built into the seat tube.
“NAGARA Self-made Bicycle Secret Research Institute”, which realized a short-time “Rinko” with various ideas in an orthodox style, came in second place.
08b “Rinko” Examination
Ranking | Number | Team name | Points |
---|---|---|---|
1 | 1 | TODABASHI cycle works | 500pt |
2 | 8 | NAGARA Self-build Bicycle Secret Research Institute | 475pt |
3 | 10 | GRAND BOIS ebike | 450pt |
Compete with the total of the judging points by the five judges for the ingenuity and technique for “Rinko”. Each judge will evaluate each team’s “Rinko” demonstration on a five-point scale from A to D. The total was calculated as A: 100point, B: 75Point, C: 50Point, D: 25Point, E: 0Point, and the ranking was calculated.
“Todabashi Cycle Works”, which realized easy and reliable packing by the wheel shaft and the wheel holding hole provided in the seat tube hidden under the BB, got the perfect score and ranked first.
The second place is “NAGARA Self-made Bicycle Secret Research Institute” which realized smooth “Rinko” by a devised attachment / detachment mechanism while equipped with a traditional style mudguard.
Despite being an electrically assisted bicycle, the “GRAND BOIS ebike”, which realized a Landner-style “Rinko” and showed hope to veterans, came in third.
Overall ranking

1 | 4 | KAWAKAMI TITANIUM | 8.595pt |
2 | 2 | Tension Silk | 8,435pt |
3 | 8 | NAGARA Self-build Bicycle Secret Research Institute | 6,845pt |
The two bicycles, which were lightweight in terms of bicycle weight, occupy the top position. “NAGARA Self-made Bicycle Secret Research Institute”, which was 4th in terms of weight, is in 3rd place with well-balanced scores in each item.
The result is that the three teams that adopted the new material (1st place: titanium, 2nd place: chemical fiber, 3rd place: carbon fiber) are the best three.
It should be noted that the 1st place “KAWAKAMI TITANIUM” and the 3rd place “NAGARA Self-made Bicycle Secret Research Institute” attracted the ingenuity and technical ability comparable to the professional builder despite being an amateur builder.
