If it's not a big nail, does that make it...a flat minor?

You should see my rim, its off my Townie Electra 21D. Anywayzzzzzz grinding v-brake pads tore through sidewall then on flat tube and tire for 4km another 4km just on rim itself. Wouldnt have been if I had the valve adapter, only been 4km. Heck I even had a studded tire hanging off me.

A few days ago, sidewall of tire tore, had the thorn proof tube, save me. Rode on that puppy for a few days. :lol: :lol:

Stocked up on more thorn proof tubes today :wink: :wink:

Slapped in a bolt on wheel, pop that out for the QR on my Townie.

This thread is from 2015.

Change to moped rims and tires, way fewer flats.

That is the plan, slowly but surely!

TBH I did not see the year, I do remember this thread though that is why I posted here. I thought that it was a year old thread maybe. Time flies by so fast these days. Was rough going, idiots driving, flat, riding rim, slipping, sliding, students going home, rush hour, train was too full. Tomorrow's another day.

I bet dogs were barking miles away... :lol:

I used to see a guy down in Ventura (CA) riding a bike sans tires on the rims... for about 2 years!

definitely garnered some looks passing by

i myself couldn't hear dogs barking or much of anything.

timbre of noise/sound changed considerably between asphalt vs concrete

vibration throughout the bike felt like an engraver

mid drive made quite a difference being easy wheel to remove roadside and strong power to this abomination

main accomplishment is that it worked better than pushing/walking long distance

This explains my rescue call, thankfully a bus was nearby, 3rd bus had a rack. With a rear flat, and a stretched out cruiser, the bike barely fit in the rack. Thankfully the bike stayed on the rack. There is another one or two cracks on other spoke holes on the rim. This needs to hold up for another week.

You know that's how it goes when you have Lincoln Logs instead of proper spokes.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.

Yup, I know, and to top it off it cost me C$85 for the spokes and nips.... locally, another C$40 for the guy to lace it because I just wasnt feeling the joy. The cherry on top, the the spokes crossed over at the valve LOL Was all done last year. Reminds me gotta find another backup rim. 2 of everything! LOL

Been having much great success of not having any flats, for quite some time now, with a front generic 1kw direct drive, laced into a 26" with a tire that has extra padding on the tread, its not the expensive one, but the alternative cheaper one. All I currently have is a very slow leak, which I just air up every fort-day.

With my weight all on the back tire, all 375lbs must've been pinching like crazy when I was doing rear hub motor, I really never really knew the cause of 50 flats, easy!

Feeling deflated.

Was riding very casually, and I got a flat. The Hemmroid flat. I was totally bummed out, 3rd flat in 5 days. Luckily today I had a spare tube kit.

Two flat tubes today.

When I switched the hemm tire from rear to front, it blew within a mile. 5 miles on a flat front, riding slow. Luckily rim stayed on tire. Rim wasnt chewed up much at all if any. Didnt really look, so muddy, so tired and felt deflated.
Made it Canadian Tire to buy two tubes and a tire.

Motorcycle/Moped tire/tube/rim time.

Treatland TV is expensive to ship.
Problem with motocycle stores, is you need a make and model to get a rim, thats all their computer systems take, so need to find brand and model of scooters with 1.20-1.40 rim widths, 24" bicycle diameter is 19" mc dia.
....or bite the s/h cost from Treatland.

Honda CRF150F 19" x 1.40 Front random guess from seller on Kijiji at yrs 2003-2017
Honda Hobbit PA50 is 17x1.20 from Treatland.

2.25 should fit balloon cruiser frame.
