on their website they have the same picture for different sizes. But i think you may find the tires with C-179 7 1 1/4 maxxis in google. At the moment i make my self some plans to build a Street/Offroad board. So no hardcore offrod. Just want to take my dog out in the woods on easy walking paths. So mainly they should perform well on the road. But i am conserned about the durability. So is there any good tyre which performs well on the road and lasts long?
Do you have a specific number how much wh you need per km. With my 90mm ABEC 78a dual drive enertion R-spec 6355 i need around 10 - 11 wh per kilometer. With my single drive 90mm ABEC 75a SK3 6374 i need around 9-10 wh per km. But i would not say that the dual needs 10% more. I would say i drive the dual harder because it is so sick.
Some other peple already suggested that with mountainboard you get about 40% less range… So if you got 10km, we would only get 6km… or so…
I still have to take more precise measurements but last time I tried to calculate the wh per km, it was in 19-20wh per km (this was done by taking the distance driven and dividing it with Ah put back into the cells, so there might be quite a big deviation, for example, If I did not charge the batteries fully, or they were already a little bit empty before I started to measure the distance…)
I also took it for a ride yesterday (with working wattmeter)… riding 2km quite fast (average speed 23kph), It consumed about 1900mah. i dont remember the exact number but it was less than 2000mah… So yeah, quite close to 20wh/km (actually ~23/24wh, when converted (24.6 assuming max voltage x 1.9ah)
So, for avg speed of ~15kph, consumtion is ~19wh/km, with average speed of 23kph = ~24wh / km
The calculation might be a little bit off, as I said - I need to do more tests
For now I do know it consumes about 10-20A when normally cruising (~10-15kph)… As I looked into the screen while riding and it showed such consumtion.
If you have a VESC it would be the best to start the board and ride a track with a specific speed. Maybe adjust the max speed to have the same speed for different tests to have a good value to compare it. And then don’t switch off the board when you are finished. Instead connect the vesc to your laptop and read the wh draw and wh charged and the tacho ABS value. Then you can calculate
Yeah, that would put some extra effort, so will see If I can manage to take a few little tests before I add pressure to them… Portable pump would be the best, I believe… as all the fuel stations around my place does not have a good runaway / straight road to test the parameters in safe / steady environment.
These are the ones we could offer. Most people don’t dare to inflate them to 65+ PSI. They roll like a dream, when inflated to that pressure. Tyre pressure makes all the difference! If you really clean your bearings and use speed cream + sack off the inner rubber seal, you will have a board rolling very efficient. Make sure your hubs can handle that pressure! Ours do.
Thanks for the great info! Can you tell how much 65 psi is in bars? Idont want to make the same mistake again - I already overinflated my wheels once and the hubs just did not hold the pressure of the inner tube… walls started to show bend marks… had especially bad it with one hub where the screw holders just broke off…
4,5 Bar = 65 PSI. Google it! Some questions can be answered by yourself, using search engines.
Speed cream is basically a thin teflon based lube.The rubber bearing shields can be removed, using a small screw driver to peal them off. Only the outer ones are really needed. Re-lube once a while. Pressure and lube make all the difference.
Your board will roll 200% better.
