Sounds like a lineup for a good project.

Thank you, took some time selecting the parts, from what i can tell it should move my 160lb ass decently lol

Re: 78 Maxi full build

Good luck! But you are gonna regret those low bars.

Re: 78 Maxi full build

i've ridden on low bars. not very comfy. much prefer high/stock bars

Re: 78 Maxi full build

do you by chance have any pictures or another set you would recommend? (edited)

Re: 78 Maxi full build

I’ve ridden a maxi for years with the long seat slammed all the way down and bars like you have listed.

It was comfortable for me and I’m 5’11” and 200lbs. I was having too much fun to notice if it ever got uncomfortable. Even on hour long rides.

Just do it if you like the looks and if you don’t like how it rides later, change it.

Leaning forward on the bars is good for weight distribution and control.

Old pic. But you can see the shape of things.


Re: 78 Maxi full build

If you're doing a top down rebuild then you should consider replacing brake shoes (depending on wear), rebuilding and greasing the brake plates, and repacking and re-greasing the wheel bearings (or better yet switch to sealed bearing axle conversion, especially for the rear wheel at least)
