Sorry if this is a newbie question but where did you get the motor? Was it a kit?
It looks sweet, but how does it ride? Could you possibly post a video?
Thanks for the positive feedback. No kit here. This thing is built from sweat and tears. The motor is a Honda / Lifan 97cc 2.5hp four stroke, flathead, sidevalve. The clutch is a Hillard #35 12T. The motor mounts and related are hand made. The rest of the parts are 90% vintage Schwinn. It rides great. I'm going to swap out a sprocket to give her a little more low end power. Right now the top speed is around 33-35mph. I'm going to scale it back a little. I'll get some video footage on youtube next weekend if I can.
Wow 30mph? thats awesome!!
wheres my welder? i am now officially gona build a 5 horse bike like this 8) once i get my welder working and some steel then ima buy a cranbrook so i dont feel bad about chopping up a jaguar :mrgreen:
That is one sweet ride man. Where did you pick the motor up from?
Here are some pictures from last weekend. I think she's all dialed in. I changed the jack shaft output sprocket from 10T to 9T. I've also added a modern rear V brake, and a chain tensioner.
The motor is a 2.5HP 97cc four stroke flathead. I bought it on ebay for $90.00. It's a Honda Lifan. I wanted a vintage Briggs, but they were too expensive for my budget.
Nice looking bike..did you fab those rear brake bosses, or where did You get them those are sweet.
man sweet build!! how did you figure out the gear reduction ,a four stoke engine would be cool on my bike not to mention way more reliable and sound better!
Very nice. Good lines on that bike.
A red tank would really set off your bike
is your sprocket mounted to a free wheel ? how did you pull that off?
The right side is pedal assist with a free wheel.
The left side is motor assist with a free wheel.
The gearing is all math. My blueprint drawing calls out the sprockets and ratios. I ended up making my jackshaft output sprocket 9T vs 10T to gear the bike just a little lower. Perfect.
The speed is now 29.4mph at 4,200 rpm.
nice job ...yourthe only other person besides me that i have seen use that motor .
i did a jessie james chopper bike with the same engine ( sounds good ) .
About those rear brake bosses?????
Yes. I did make the rear brake bosses. Here is a tread I started showing how to make them.
Just put on my tank decals. Next is custom exhaust, heat shield / guard.
I like it. Can you take a picture of the right hand side of the bike please?
Here are some pictures of the right side of the bike.
