in this video I'm going to be showing you guys how you can build a weed whacker bike alright so the scene I'm showing you right now is one of my earliest weed whacker bikes this design is terrible so one recommend doing it but I'm showing a different design in this video as well cleaner design and vehicle so this is the different design it's the mount here that I'm showing and this is how we do a car engine that is also on display here and what I have is on the bottom bracket there it's bolted in once you take off the plastic covers you'll see two bolt holes and that's where you'll bolting bolted onto the metal and in that same area there's also flywheel so you'll have to cut a curve into the steel so that the engine fits properly and here I'm showing you guys how you can cut a curve into the steel you can see the black marker that's where the flywheel would go and what you do is you just cut a bunch of tabs into deal and then what you do is after you cut all the tabs into the steel you break them off as a large ring and here I have cut all of the tabs into the steel and I'm going to be breaking them off with a wrench and it takes a bit of force to get the first few out but once they come out you just wiggle and looks and they break off pretty easy that looks to it and here I have just broken off all the tabs and I'll be cleaning up to the edges with named grinder here here you can kind of see where it mounts into the bike this is where most of my designs have mounted in to see where the brake that's not good fat but conceal the brakes kind of hook up I have u-bolts covering the bolt bring that that's how it mounts to the bike and yeah that's it for this bike just thought I put in a quick little clip of me riding the bike um its friction drive so to start it's a just pedal to start and I'll go up and down the street a couple times so this is the bike done in a design software I'm using Sketchup the engine is mounted to the bike the same way my bike from before was where I'm hooked up into the brake caliper I'll show a better shot of that but this is just a quick panning around of bike there you can see where the two mounts for the engine mic up and go into the bolt or well it's just white on here but I usually use a 5/8 threaded bolt and X kind of as a hinge for the tension here I'm zooming in on where it's knocked it to the bike and I usually use u-bolts in that area and that is the 5/8 boat that I was talking about there highlighting the linkage prison or hinges and is the bar and back there that's what I use to keep the tension or the weight on the wheel it's bolted to the end of the mount I'm going to zoom in here not really zoom in but there it just goes down to the axle on the bike and you just make sure it's got enough pressure on the tire so you can start it in middle keep running without less problems and I'll be showing what this looks like in real life here in a couple seconds so here's that bike and I use a bicycle peg that's what the drivers on the wheel you can see where I had it mounted onto the bike use u-bolts and the engine mounted and then I use that bar on the left or now on the right that goes down to the axle and keeps tension on
