    Well let me start by saying I should have known better.

    I knew the flat tire thing was going to be a bummer if I got one while too far from home. I ordered thorn proof tubes, tuffe tire liners and put tire slime in the tubes and installed Velox rim tape. I did my wife's bike front and rear but just had time to get only my rear done. I figured the rear was the worst one and I do Carry a patch kit in my back pack.

    Well on my way home from work at 3am I got a flat on the front. To say It was disastrous is an understatement. You see the seam in the Tube split. It went from air to flat in a nanosecond at twenty plus miles per hour. The tire flopped side to side on the rim and became almost impossible to control. If I used the rear brake it was worse. I slid my body back over the rear tire and slowed with only the throttle and did my best to keep it going some what straight. When I got to less than 5 miles per hour the tire violently would bunch up and flop side to side with literally no delay between swapping sides of the rim.

    I got down to under 2 mph and the tire bunched up and acted as if I was applying a brake to only one side of the fork. It turned the tire abruptly right and I steered it left but to my horror the stem turned in the fork. Over I started to go with the handle bar trapping my left leg against the fuel tank. I caught myself with my hands a hung there like I was going to do a push up with a half twist. I tried to determine how to get free of the handle bar and my whizzer and finaly wiggled my way out.

    I had no injuries other than where the compression release lever on the handle bar drug down my leg causing a scrape 8 to 10 inches long going down my left thigh.

    I am telling you this story so you will not need to learn the hard way like I did. I hope that you may learn from my error.

    1. Use a thorn proof tube at a minimum
    2. Use Tuffe tire liners
    3. Use a new proper sized cloth rim tape (Velox)
    4. Consider tire slime

    Consider better quality tires and ensure your stem is tight and will not slip when you hold the tire between your legs and turn the bars. Yes test it do not consider the allen bolt to be tight enough to be OK. My bolt seemed tight enough but took a full turn to lock the bars solid.

    I was very lucky and only scraped my leg, scuffed the tac housing, edge of the front fender and edge of the left brake lever. I did not break or damaged anything else. I did not even scuff myself on the pavement since I was effectively stopped when I went over.

    Learn the easy way, from my stupidity!

    PS: I am going to try the new airless tires. I read about some that are being tested to be DOT certified for motorcycles and cars. I called the manufacturer and even spoke with the owner Kai. I found out they have these available for bikes now. I ordered them and will report back my findings.

    thank you Kep1a --- for reminding us --- to be ready at all times --- blowout !!

    sometimes while riding down this mountain with next to no bike lane
    cars and buses are passing very close at high speeds
    there was a thread around here about threading the needle - someTHING like that
    stating that those known dangerous riding places
    become better in time -- as we ride them more -- riding experience gains

    I am not very sure about that
    this mountain riding scares the heck out of me
    and if I would have a blow out such as you explained -- MAY BE A KILLER

    my first crash on a motor bike was at the age of 6 or 7
    7 1/2 hp -- over the handle bars at 35 or 40 mph
    woke up some minutes later my grandfather said

    as you did -- we got to walk away -- that's always a blessing

    have fun as you ride that THING

    Glad ya got er shut down, as well as you did! (minimal injury & damage....coulda been really bad)

    Thanks for posting this "Wake Up Call".
    Lots of good points to think about!!

    I am copying this thread to "General Discussion" as these issues effect ALL of us & not just the Whizzer riders

    thanks again, Kep... & glad you are ok!!

    OK Folks,
    I believe my tube was rotten and was likely the cause of the failure. I can tear the tube with little effort or stretch. This is not how a rubber tube should react to being stretched or pulled. My wake up call to the real hazards of a flat tire motivated me to look for a solution that would be fool proof.

    I ordered the solid urethane tires 26 X 1.95 all terrain tires on Friday. I will give it some time to tests them before I report my findings. I will also post pictures before and after I mount them. Price was $33.60 plus shipping and $2 for the installation tool. I doubt the tool is needed but I ordered it just to be sure.

    They told me that they ride like a 55 psi firm rubber tire and I can expect about 6000 miles of tread life. The tread is not the limit of wear however. You can run the tire much longer than that if diameter and the disappearance of tread is not an issue for you since the material is the same all the way through.

    They have 16", 20", 24", 26" and 700c for bikes. all but the 700c have 3 tread and two width sizes (1.75, 1.95 in ribbed, all terrain and knobby)

    I am very hopeful that these tires work out. My blow out was very scary and I want to avoid the possibility of another incident if at all possible. My fingers are crossed.

    Can you post a link to these solid tires? I have heard good things.

    I also had a flat a couple days back.... I had to push my bike the last 2 blocks home....coulda been worse!
  6. I looked into them for my motorized road bike. Saw a lot of complaints about the feel. It was described as running on slightly flat tires. Not a trait I wanted in a bike. I hope your experience proves otherwise, because it sounds like a "solid" idea.

    hey you all -- motor bike riders

    Large Filipino has a thread regarding solid tires ----- No More NoMoreFlats

    might wish to check it out --- pretty interesting

    ride that THING on good tires

    personaly never used them because im afraid they will grow with speed, diameter, i hit 47mph+ regularly on one hill going down and if a tire came off the rimm at that speed i dont think my DOT helmet will save the rest of me. will they grow?

    I think those "no more flats" are solid tubes, that go inside tires.

    Regardless, Kep1a's comment about going at least to a thorn-proof is very sound advice. I went to a thorn-proof on my rear tire after two flats in a month's time. Changing out a tube on a Whizzer's back tire is a bit more complicated than it is with either of my HT-engined bikes, so I went to the thorn-proof there.
    But making sure that you minimize the chance of a catastrophic blowout on the front tire is indeed sage advice. A blowout on the rear is an annoyance and an inconvenience. A blowout on the front that could cause loss of control can be far worse than an inconvenience. This is another thing to add to my winter "To Do" list.

    "i hit 47mph+ regularly on one hill going down and if a tire came off the rim at that speed"

    I don't think that will be an issue because he was telling me that they sponsored a trike land speed record that hit a max speed of 78 mph. The only issue he had concerns about was long sustained speeds over 30 mph with our summer heat with 117 air temperatures. Our road temperatures can exceed 160+ here in Tucson. I have seen motorcycles fall over because the asphalt gets so hot it melts and allows the side stand to sink and the bike just falls over.

    They sent me cutaway samples that you use to check the fit on your rim with and I was impressed with the fit on the Whizzer rim. I can't see it coming off on it's own under any stress loads seen by a motor scooter or bike. I will take photos of samples and how it fits tomorrow and post them.

    I am not yet able to test them and as of yet can not recommend them. I will however post a link when I post the pictures of the samples. I got the link from an article that was covering their product DOT certification testing for use on passenger cars trucks and motorcycles. They did not however have an estimate on when the tires (Tyre) would be available for use on cars and trucks.

    Link name came to me so here it is...


    Bike tire info is a little hard to find so here is the easy way to get it.

    PDF catalog:

    Go to the last page of the PDF and you will find the bike tire information.

    I am told the tread selections are a little different and availability of the size and tread needs updated as well. He said it is an old PDF and needs to be updated. He also said they are putting all their time and resources into their product development and the DOT certification process.

    Here are the samples I spoke of. The rim is my front rim but the rear is the same. They only sell black now so yellow is no longer available. Once the entire circumference is on the rim it will squish the bead in even tighter and essentially make it necessary to cut the tire to remove it. the sample when squeezed seems close to my 26 X 2.225 with 65 PSI although the tread feels stiffer. I imagine it will have lower rolling resistance too.

    I can't wait to try it and see if it is going to work as antisipated. Photos were rushed so if you need better resolution let me know and I will put more effort into getting lighting, distance and focus better.

    Well the tires came in today.
    Although I came down ill yesterday I just had to pop the front tire on since the tire and tube were already off and I had the wheel already off the bike.

    I must say it was a little more than just pop it on though. I finally gave up and asked the wife to help hold my progress on the one side while I worked it on from the other side. I was chasing my tail going around and around dismounting just as much as I mounted as I tried to work it on the rim.

    Note; It will not fit unless you have the bead/lip seated in the rim everywhere as you go around it in an attempt to mount it. With the wife holding my progress I was able to force the tire on by hand. It did take quite a bit of force though.

    The tire seems like all I had hoped for although I wont get to ride it until I'm feeling better. In my condition just mounting the one tire made me want to go back to bed :sweatdrop:

    good looking tire..... a tight fit should insure it won't move around.

    Kudos to the Missus, for helping!! :2thumbsup:

    Hi Kep1a, Hurry up and get well. Can't wait to hear your test results.

    Merry Christmas & Happy New Year
  16. I think there is something going around Tucson. I got it too.

    Didn't notice before that you were here in town. I'm always up for a ride and would like to see those tires first hand.

    Yes for sure I will update as soon as I put it all back together and ride it. I'm feeling better now but the weather is not cooperating right now. Rain, snow or both and way too cold for this fair weather rider to venture out on a bike. Hey I don't like cold weather one major reason I live here where it rarely gets cold. :)

    I do notice the tire is considerably narrower in appearance once inside the fender. More easily noticed with the OE 2.125 still on the rear and the new 1.95 on the front. Otherwise the new tire is a perfect fit. Tire still feels a little pliable even a 30 degrees.

    I doubt I will get time for a recreational ride. I have not even had time to do that with the wife all this year. My riding is somewhat restricted to my commute to and from work when time and weather permits me to that is. My full time job plus being the general contractor and cheap laborer on our new home keeps me very busy. I might be able to leave a few minutes early for work on a day a ride and meet up with you so you can check it out. PM Me so we can swap information and see if our schedules will permit us to meet up.

    OK first update,

    The tire if left in the sun an hour or two goes on very simple and with no help if you ensure the bead is fully locked in as you go around the rim with the tire. The fit on the rim seems perfect to me.

    My first impressions after a quick loop around the block before I had to go to work.

    1. The tire has a very firm but not at all harsh ride.
    2. The rolling resistance is noticeably less. (Like a high pressure tire)
    3. Turns and feels almost sporty.
    4. The narrow tire gives the bike a board track racer look.

    This narrow tire gives the bike a board track racer look has lots of room inside the fender now. At first I was put off by the little tire appearance but that look along with all the positives that go with that smaller tire grew on me very quickly.

    I need more ride time before I give it a full seal of approval. So far though it has been a great choice for me.

    I do not see where to buy these tires on their website. I would be very interested.

    I just called their toll free number and they immediately sent me out the samples via first class mail. I just called back and ordered the size and tread I wanted via the phone. Bike tires seem to be a we also sell product for them. I had my tires in 3 days.
