I am looking for a hub 110/20 for 3 mm spokes?

Those tires will fit your rim, however, a 90/90 tire is going to be closer to 3.75 inches wide. Thats a big tire. You would really be better off going with a Shinko SR244 2.75-19 tire which is about a 60% road 40% dirt tire for motorcycles, but for ebikes, it can be a 100% road tire with no problems.agedashidofu wrote:Hi folks,
Was wondering if anyone can help (apologies in advance if this question has been answered)
I currently have a QS205/50H V3 motor set up on a 19" X 1.6" rim. Does anyone have any recommendations on which "road tire" will fit? Will be mainly using this to commute, so looking for a good road tire that will fit.
I've currently stumbled on a Dunlop D401 90/90-19 (width between 2.75 - 3.00) which has great reviews - but says recommended rim is 2.15.
The other one I found was a Pirelli MT66 90/90-10 (width between 2.75 - 3.00) - but also says recommended rim is 2.15
Do you think they will fit into the 19X1.6 rims?
I can't for the life of me, find any "road tires" that will fit on these rims (can only find offroad tires)
Many thanks in advance for your help!
By "wheel" and "rim", do you mean tire and rim? Or do you mean wheel and frame?DasDouble wrote:Have just tried to put a 80/90-21 wheel on my 24" rim.... This does not fit... Bullsh*t!
I meant a 21" moto tire on a 24" bicycle. Now I will go with the 70/100-19 F546. Looks quite neat and seems like it will fit on my 24" mtb rim.Chalo wrote:By "wheel" and "rim", do you mean tire and rim?

Whichever you mean, a 24" bicycle rim measures 20" at the bead seat. So hypothetically, it would fit a 20" moto tire (though spooning it on might damage the rim).
It wont fit on a 24MTB rim, the bead will blow off the rim as soon as you exceed 5 PSI. Traditionally 24MTB rims are 20" OD, your typical adult size dirt bike rim is 21"x1.60 wide.I meant a 21" moto tire on a 24" bicycle. Now I will go with the 70/100-19 F546.

Also there is a thread here on ES about the Myth, its long, but it mostly makes sense to me now.One false and oft-repeated conclusion is that therefore the 409 is a higher torque motor than the 406 because it can produce the same torque with fewer amps, or likewise more torque with the same amps. This is not the case. All 400 series motors can deliver exactly the same torque at exactly the same efficiency. The lower winding count motors just need more current to do this, but because they have fewer turns of a shorter length of heavier gauge wire, they can handle high currents with minimal loss. To use a concrete example, lets compare a 404 with a 408. The 408 has twice the number of turns than the 404, so the copper wire in the windings has 1/2 the cross sectional area and twice the length, for a total of 4 times the winding resistance of the 404. For a given torque output, the 408 needs only 1/2 the amps, but because it has 4 times the resistance the net electrical loss (I2R) is exactly the same.
Another consequence of having a larger number of turns around each stator is that the voltage induced in the winding by the passing magnets is increased in direct proportion to the number of turns. So for instance, at a certain speed of rotation, the 408 motor will produce twice the back-emf voltage as a 404 motor rotating at the same RPM. To power a motor, the battery pack voltage needs to be greater than the back-emf voltage, and so the 408 motor needs twice the voltage to spin at the same speed as a 404. However, it will only draw 1/2 the current, and you can see that the net power input (Volts * Amps) remains the same.

A 19 is the closest match to the mtb 24" wheel.

Looks great!
Where did you buy your tire and tubes? Trying to source some over here...
Got a michelin 70/100/19 tube,and the 2(.)75x19 trail tyre of ebay or u can get 3.00x19 tyre.
I have tried a 21" moto tire before and it is way to big to fit on my 24" bicycle rim. Now order is already made.. Lets have a look what a 19" moto tire looks like on a 24" bicycle rim...Rix wrote:It wont fit on a 24MTB rim, the bead will blow off the rim as soon as you exceed 5 PSI.

What about this dude? He has done that. Also motorcyle tires last way longer then bicycle tires. I have tried the 24x3 one from LMX I think it was and its now already done, down to 1mm while my rear motorcycle wheel still looks like it has 80% of its rubber left. And I never brake with front break by the way..brumbrum wrote:Trying to fit a motorbike tyre on a bicycle wheel is ridiculous. Its not going to happen, and will lead to disaster. Would you really feel confidnt going 50mph on an ill fitting tyre and rim combination?
