451 wheel models? 22"

How soon, if Tern markets one, will we see a folder with the "451" spec, so called 22" wheels that might fit in a standard 62" suitcase? i was noticing that even Cruzbike has a model, the Quest, that fits in the Flite cases. I detest paying an outrageous fee to check an oversized bike or being hit with a bicycle luggage fee.

As a dealer I realize the issues with 451 tire availabiltiy but I think a rider that has the 451s will have a spare along in ares where they are hard to find. I would. Perhaps Tern has a 451 in the lineup and I missed it!

As you can tell by my posts the bikes that travel as checkable baggage are important to some of us and I think it will be growing trend. America is not like Europe where you can ride between "cities" or even nations in half an hour or 45vminutes in some cases. This is a huge land where I frequently fly over 1000 miles and then use the bike. I think this is pivotal.

Folks in large urban areas can and do cycle-commute locally but:

What about those trips to far away places where you want a very "roadable" machine after you arrive? So far 20" wheels is all that we had....until now.

Your thoughts?

We’re happy with our 20” and 24” wheel sizes. We’re working really hard not to have model creep and end up with lots and lots of finely differentiated bikes with all different sorts of custom parts. We want fewer models, really well engineered.

Josh and Thor,

Nice to now what you want Josh. I just hope something less exotic will come along in a 22" or so with Big Apples for suspension. It has to fit in a 62" suitcase though. It makes no sense to the average pesron to pay ridiculous oversize fees to carry a checked bicycle within the states. Removing the wheels, seat, bars and pedals is no problem.

The custom "solutions" like Friday that are out there are not so great, are overpriced, and they do not all fit in a standard, checkable case. I do not want to see 22" fatties introduced to complicate "model creep" or the ease of tire replacement issues but because they simply make more sense than 20" for stability and comfort. Brompton is very poor on low speed stability. Smaller wheels=wrong direction to go, Especially for folks well over 6 feet tall.

Pardon my use of Western style tire sizes but the metric numbers do not tell the entire story at least to me. A so called 22" metric may be almost as small diameter as a 20".

Thor can you run Big Apples with sufficient clearance on your slightly larger rims? In what TERN frames? With fenders?

 

Ciao!

Hi Thor the 451 show as a 20"equvqlent in the ISO charts. I am talking about 22" equiv or 457. 22x1.75x2.125.

Is there a Big Apple that fits the 457 wheel? I may just construct or modify a frameset for a test.

451 are indeed 20 inch tires,  just taller ....


roughly 50 mm difference in every complete turn of the wheel ......  which is not insegnificant... 


All the conversions we made are for "racers" the last thing they want is fenders or anything else of weight, so I have to admit that I dont know if fenders will fit.


The same about big apples ...I doubt they even exist .... they might ... but again everybody with the conversion to 451 loves skinny high pressure racing tires ... 


 


getting tires for real 22 inch wheels will be almost impossible... :-(


 


Happy Thanks Giving Thor

Hi Thor,

Thanks for the reply. I will work on this and see what is up. I just do not see a practical 24" wheeled folder that will fit in a 62" case without total disassembly. It does not hurt to wonder.
