In a 14 inch dirtbike rim with a nice fat tire this motor would look right purdy on my rediculously over built 70lb full suspension recumbent. Not to mention that I have an 18 fet lyen controller that has been itching for a good modding for some time now, and this looks like just the excuse to finally go through with it.
What is your source for the 14" rim and is it 36 hole? Im looking for one myself for a fast wind motor particularly if it will take a 14" road tire. What will the overall height of the wheel and tire be?
Well, the rim is easy enough, that you can grab off of eBay from any dealer of chinese dirtbike parts ( I tend to favor the "chinese motor parts" eBay store but I think they may only sell built wheels). There is actually a whole wealth of cheap super light generic chinese dirtbike parts that are a little too flimsy to be taken serious by any hardcore motocross buff, and way too over built for any serious bicyclist to consider weighing down their 17lb $3000 carbon fiber tour bike with, but perfect for people like us who are building rediculously over powered ebikes. I just put a pair of dirtbike forks on my semi-recumbent cruiser build, and although the extra 12lbs stings a little on the hills, there is nothing quite like 5+ inches of travel to put the fun factor back in your daily commute (curbs have effectively lost all meaning to me at this point, and thats running a 5302, who knows what shenanigans will ensue once I get my hands on something with even a modicum of low speed torque). I figured, hell, at $60 for the pair, I can always put them on a different bike if I don't like them on this rig.
At any rate, my plan was to rig something custom out of aluminum plate since your spokes would be probitively small in a 14 inch (read 16" in bicycle terms, with a tyre my total wheel diameter should be about 18") dirtbike rim. If it weren't for the motors coming out cockeyed this run I probably would have experimented with attaching the tyre directly to the hub itself, but that will likely be a bit difficult at this point unless I want to upgrade to a motorcycle swing arm to give myself some play in the wheel position. As it stands, I'm still looking at some sort of custom hack to almost directly interface the rim with the hubany way I slice it, and the cromotor will probably obliterate the first few attempts, but this kind of thing is not that uncommon with scooter hubs so it should be doable all the same.
