Iv aligned every thing correctly and it all fits.
The boosted board motor pull is a 16t 15mm wide cog. The wheel is a 5inch 1.5inch wide pneumatic with a 70t 15mm wide cog. Top speed will be only a little higher but it’s nice gearing so it will retain a similar performance.
The problem I am having is the belt is rubbing on the inside on the cap as the angle is greater then the original small 50t pulley.
My plan is to use a belt roller of some sort or a modify the cap.
What do you think?
I have no advice to give but just want to say that this definitely belongs here. That is a sick DIY! Hoping you’ll post some more pics down the line when you complete it!
where did you get those 5inch pneumatics? Personally I would just Dremel on the cap until it fits - but I have never seen one live so can’t confidently say that is actually a good idea.
Richard from alien drive systems use skike wheels they have discontinued there 5inch but they have an 6.25inch that’s sweet, would give 30mph but would cut into the torque. They also need modification but they have a very low road resistance.
@jacobbloy@Maxid The search for good AT wheels is tough! I currently used modified 5 inch skike wheels and they are pretty good, here are some thoughts on them:
The high psi means low rolling resistance so they are fast, but still smooth out the roads. I don’t fear every pebble or crack on the road.
The tires aren’t very robust so the drive wheel tire burns up pretty fast (I get about 120 miles per drive wheel tire).
The QA for the tires and tubes is not very good, so it’s common to get a tube or tire that is not true and has significant wobble even though it’s new. I’d say about 30% of tires or tubes have a problem.
Skike stopped making them. Once I use up the spares I have, I’ll need to look for a new AT wheel.
I think that 5 inches is the sweet spot between good road performance but still compact enough to carry around like a skateboard; 6" might be OK as well. The new 7" Evolve wheels look OK. My first choice if I could start over would be @psychotiller’s hubs.
Yea guys back on topic, apparently it looks like the boosted board original belt actually rubs on the inside of the belt cover, it looks like it’s been machined like this.
I don’t know how much this would effect belt wear but maybe it will be ok if it’s touching on this wheel also, I’m buying new belts tomorrow so I can test it.
