=================== ANNOTATION: ====================
IN HAND TEST OF SCOOTERS Y-SCOO 205 AND Y-SCOO 230
Contents: (possibly download: https://yadi.sk/i/Wv_WP7JSiRnSR )
================= PART1: Y-SCOO 205 =================
02:40-05:15 - short review of Y-SCOO 205 with the air wheels
06:28-10:15 - pumping up the tires. Key moments:
1. Pressure must be at least 4 Bar (4 atmospheres). Smaller pressure makes rolling worse.
2. Leakage of air in the moment of disconnecting pump can significantly decrease pressure in the tires as result of the very small volume of tires.
10:30-13:40 - driving to test section; description of test.
13:40-15:10 and 52:52-54:12 Y-SCOO 205 rolling test.
Results of 3 attempts: 62 steps (omited in video),
68 steps and 73 steps, where 10 steps = 9 meters (even little more: 1 my step prove to be equal 1 yard :-)
15:10-19:18 - test on road: first part of road: good asphalt but with
cracks and dents; second part: bad asphalt with gravel etc.
19:18-20:14 and 54:36-55:40 - motion on gradual descent without
pushing. Both times Y-SCOO 205 was stoped exactly
than asphalt is over. Tilt was over in 56 sec. and 64 sec.
20:30-22:25 - conclusion. Key moments: with the full pressure
(4 Bar) scooter practicially gives dual benefit of motion
speed vs walking. But with 3 Bar pressure benefit is
smaller and it's more difficult to push it.
22:40-24:20 - explanation, that jolty and rattle in video are effects of
amateurish shooting. Really Y-SCOO 205 moves very
smoothly and quietly even in jaggies.

================= PART2: Y-SCOO 230 =================
25:03-35:46 - short review of Y-SCOO 230 with the hard
(maybe polypropilen) wheels
35:47-37:00 - driving to test section; on the bad asphalt this
scooter rattles significantly more.
37:22-38:59 and 39:00-41:34 Y-SCOO 230 test of rolling.
Results of 3 attempts: 75 steps (omited in video),
77 steps and 99 steps; 10 steps = 9 meters or 30 foots (or feet?... How right? :-).
Distance strongly depends on starting;
41:35-45:21 - return way on the good and bad asphalt.
45:22-46:06 - motion on gradual descent without pushing.
At the end I had to use brake because speed still was
hi enough. This tilt was over in 44 seconds.
46:30-49:10 - conclusion: hard wheels give a little benefit of speed,
distinctly easyer to push it, but scooter strongly jolted in
tile or bad asphalt with gravel.

= PART3: SHOOTING IN 6 DAYS AFTER PUMPING (Y-SCOO 205) =
49:35-52:48 - conclusion and additional test of this scooter
(without additional pumping up)
52:52-55:45 - additional tests Y-SCOO 205 on rolling and gradual
descent. Rolling even better!
===================== SUMMARY: =====================
1. Both of these scooters are suitable not for children only but for adults also (my weight with my bag is about 100 kg).
2. If at least 80% of road has a good asphalt the Y-SCOO 230 more preferable. As this procent decreases air wheels of Y-SCOO 205 become more preferable.
3. Time to get to my job: by feet - 22 min, Y-SCOO 230 - 10 min, Y-SCOO 205 - 11 min with 4 Bar pressure in tires and 14 min with 3 Bar. But to push Y-SCOO 230 a bit easier than Y-SCOO 205 anyway.
4. Pressure in tires of Y-SCOO 205 In 6 days after pumping up still hi enough. Rolling became not worse.
