I agree with Onur, fixing A-bike typre punctures will never be my favorite. I had 2 punctures in 2 days in the rear tyre and had to fix it without removing the rear wheel. The bolts counter and clockwise were set dead thight. The videos on this site are however helpfull.

Dear MAtt Chapmann, Alex Karogroulis

I am an A-bike owner more than 8 months. Age 49 and 82 kg, own two kick scooters, a brompton and a-bike for urban commuting, I barely use car in the city, combine public transportation or cab. Among all of them a bike has a good niche that the others do not have.
In 3 miles range, on wet surface, a bike runs nicely, kick scooters do not.
Brompton is heavy to carry in and out, but best with high load and longer journeys, indoor carrying to building is possible.

Every day ahead of time I have to plan what I want to do, what the weather is, which commuter is the best, it is fun.

My biggest problem is flat tires with a-bike, scooters have PU tires and never puncture. Brompton has reliable tires never punctured in late 8 months.

==One of the reason lose air by the time and puncture on the metal rims of the wheel. ---I bought the schock pump and learned to pump weekly,
==Second reason may be my weight and close to range ---------I began to diet, lost only 2 yet.
==Third reason may be the wheel design. This is a 15 mm high pressure as said by contributors, tire is harder than people use in the video, it takes longer to build it back than video, sometimes inner tube punctures although you do all the steps on the video, because of hard job.
Now days although I repair the punctures, I experience more re-flats from the repair site.
------I am wondering is it possible to increase the back tire diameter to have sturdy design?
------What do you recomend me rather than loose weight?
------Trikke scooters designed PU and Air tires for interchangeable usage is it possible to have PU rare wheels? Like Xcootr scooters has nice 18 cm wheel with narrow rubber touch on the street, why you do not use such a tech.

Finally, this is a nice machine, but rare power tire is problematic,
punctures offen, heats more and decreasing the stability during move.
Sometimes it flats during air travel in the bin doing nothing.(a-bike is
the only bike you can take to the cabin with you without restriction).
What do you recommend for problem free driving like scooters and brompton? May be rubber back tires no air in it. Why air? 90 PSI makes them like a rock, sometimes inner tire makes bubble you shake on the road.

Best regards
