I picked up this bike about a decade ago in Newport Beach, CA from a personal friend of Horst Leitner. It was pretty dirty and in serious need of maintenance, but the kid in me that used stop by the LBS every chance I got to ogle the Mongoose Amplifier sitting on their showroom floor insisted I pick it up as a restoration project.

Once I started the restoration I noticed something unique I haven't seen on any other B2. Take a look at the way the chainstay is attached to the front triangle. On every other B2 I've seen there is a mount point/pivot welded to the main triangle, but on this frame there's a removable bracket. Also, I thought it was pretty cool that the serial number under the BB is obviously hand stamped.

Take a look at all the pictures and let me know what you guys think. Interested in hearing thoughts on value and if anyone has ever seen a similar B2.

The original grips were trashed so when I finished the restoration I picked up some classic Ourys that I thought fit the time period of the bike. Also, the tires don't match at all but are on there just so I can occasionally take it for a spin around town.

I'm a newb here so I can't post photos yet but I did upload an album you can see on my profile. Maybe a more seasoned user can post them for me?

You may be able to look up LEitner himself -- If that is truly a one of a kind prototype, it would be tough to put a value on it

I also dabble in motocross and raced in the days when Horst LEitner was an active designer. He was a mad scientist of sorts. That is a very nice bike you have

I own a B-2, but mine is more pedestrian, Black and only for rim brakes. the disc mounts are cool.
Only trouble I found was that the removable rear brake bridge gets in the way of tires over 1.9" wide on mine.
I bought it over a decade ago and never built it up, belonged to a "bike of the month" rider. I think he bought an ibis with the flat strip chainstays, "bowtie?"

Thanks for the pic assist!

That would be cool to get some feedback from the man who designed it. Didn't know his roots in motocross ran that deep, thanks for the article link!

Yeah, I remember the brake mounts on the seat stays were a bit of a weak spot with such thin and light tubing. And that little 'butterfly' brace wasn't nearly enough to keep the flex down. I'm not sure I've seen another B2 with rear disc brakes either. The rear hub is just an off the shelf Shimano with drilled and tapped holes and then there's a machined aluminum mount that is attached to the hub. I was able to track down a digital copy of the original owners manual when I was doing the restoration which helped a ton when rebuilding the brakes and rear shock. Both of them were spec'd with plain old ATF instead of shock oil or brake fluid.
