Not so Budget build

This is my first post, but my second motorized bike. The first was a Kent mb with a 66cc that i bought completed. It was great, but I gave it away a few years ago before ever doing anything to it.

I've built a 48v/1600watt scooter for running my dogs that I gave to my nephews, and a 48v/1000watt fat tire mb that i still own at another property. my main complaint about electric bikes has always been up-front cost, don't store well, and break-fix cost. It seems if you let the ebike sit for a few months and come back, something is now not working... moisture got to something... your $400 battery is half the ah or totally bricked... something.

So I decided last month to try a cheap yd100 budget build for going 8mi back and forth from the store. Here's my initial plan.
150 for schwinn sidewinder
115 for ebay yd100 kit
53 for 56t+adapter
12 for double brake lever
6 for shorty cnc intake
Plus a few bolts/etc

Total $350. Now the "but".
I ran the bike over backing out to go get the packages. I destroyed the front wheel and fork... so updates costs:
50 for a solid fork with disc brake mount
20 for Craigslist 26" wheel set

we're now at $420 and haven't even got it started yet, but finally... it started.

The shorty cnc intake on this bike puts the carb in a angle that seems to flood the motor, so the carb either leaks wildly or won't start after float adjustments. I'm currently waiting for an offset intake that I'm hoping I can bent enough to get the carb to sit level, and while I wait I ordered an nt carb, air filter and 10mm circle clips.
12 for nt carb
8 for circle clips
7 for offset intake
5 for cone air filter

~$480

Still waiting...

Friction????

Chain drive triple chainring shift kit.

Jerry has a chain drive! hell chime in, a second to rip ya one.

Hahahahaha...My bad...lol...I even knew it was a chain drive just from other pics...I just always think FD when motor is in the rear...lol...lol.

I have an older Ranger, its about as tight.

I took the standard intake, chopped, used a 5/8 copper elbow, joined it with fiberglass wrap and JB Weld. Added a shim jb welded to wrap carb end and work the tip to mate the O-ring.

Tore up a lot in 800 miles but that part is solid.

Common myth, most people think all rack mounts are friction drives.

Jerry won't be able to answer that one for ya...lol...He's a four stroker, rear mounted motor with friction drive, not a two stroke guy...lol...Here is a pic of his build.

Ah! Saw it in the grocery getter thread. Just didn't put the name to it. I've only seen 2 sidewinder with 80cc 2strokes, both are older bikes with more room to mount the 80s

I should have got a cruiser, but wanted gears and disc brakes

I didn't want the gears but I did want the disk brakes...I also did not want the hassle of always adjusting spokes and truing spoke rims so I went with a Hyper Bike Company beachcruiser and did this to it...lol.

Awesome job! I hope to bent the offset intake to get level, but I've been thinking about having it come out the side exactly like that rather than fight the seat post.
I may use the cnc shorty flange as a shim too, and grind it to whatever angle I need.
Thanks for the inspiration

That's a really nice bike, but wheels alone cost what my entire bike cost.

 

[DAMIEN1307]

but wheels alone cost what my entire bike cost.

They only cost me $119.99 when I bought them in 2020...Thay also included the disk rotors, the calipers, brake pads, 36 tooth sprocket, and spacer for in between sprocket and disk rotor...They now sell for $149.95 with everything I just mentioned...Just pick the rim colour...lol.

Many of us here don't mind spending what it takes to make our bikes safe and reliable.

To be fair, the engine Damien and I run costs nearly as much as your initial build all on its own. 270 to 300 bucks depending on it they have a sale or not. It's also at least 2 to 3 times as powerful, hence the price tag.

Neither of our bikes are budget builds other than the frames we started with.
